Coupling of leaf economic and hydraulic traits of desert plants of different life forms in the Ebinur Lake Basin

The functional traits of leaves and their internal trade-offs have been the focus of ecologists as a powerful basis for revealing plant physiology and function, and ecological strategies. The consistency of the coupled relationship between leaf economic traits and hydraulic traits among trees, shrubs, and herbs in similar ecological environments has seldom been systematically explored. We explored coupling in desert plants of different life forms and their response to the soil environment in two tree species (Populus euphratica Oliv. and Haloxylon ammodendron (C. A. Mey.) Bunge)), the shrub species (Nitraria tangutorum Bobrov and Halimodendron halodendron (Pall.) Dum. Cours.), and herbaceous species (Alhagi sparsifolia Shap. and Apocynum venetum L.) in the transition zone of the desert in the Ebinur Lake Basin, Xinjiang, China. Leaf and soil samples were collected to determine plant leaf economic traits, hydraulic traits, and soil factors. Regarding leaf economic traits, trees had higher in leaf mass per area and leaf thickness (LT). The leaf nitrogen and phosphorus contents were higher in shurbs than those in trees and herbs. Regarding hydraulic traits, shrubs had higher palisade parenchyma thickness (PT) and vein density (VD), whereas herbs had higher stomatal length (SL), spongy parenchyma thickness (ST), and leaf water potential (Ψ). In herbs, SL, ST, and Ψ had advantages, whereas PT/ST was the lowest. This study revealed an association between leaf economic and hydraulic traits in plants of different life forms in a similar ecological environment and provides a scientific basis for plant conservation strategies and ecosystem services value assessment and use in arid zones.

Resources of Melliferous and Polleniferous Plants of Central Asia and Kazakhstan Based on Melissopalynological Analysis

Abstract—A palynological study of 82 samples of honey from Middle Asia and Kazakhstan was carried out in order to determine the resources of the key melliferous and polleniferous plants. The obtained results made it possible to establish 8 productive beekeeping zones in the studied territory. The most common pollen combinations are identified for each zone. The selected zones can be combined into two large groups: northern and southern, with a transitional area (zone 3, the Dzungarian Alatau mountain ridge) between them, where honey with mixed palynological characteristics is obtained. In the northern part, in zones 1 and 2 (northern and eastern Kazakhstan) Origanum vulgare L., Rubus idaeus L., Salix L. are important wild native melliferous plants, Helianthus annuus L., Sinapis alba L. are agricultural melliferous plants, and Filipendula ulmaria (L.) Maxim. is important polleniferous plant. Further south, in zones 4–8 (south and southeast Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan), the principal wild native melliferous plants are Salvia L., Thymus L., Alhagi Tourn. ex Adans., Halimodendron halodendron (Pall.) C.K. Schneid., Tamarix L., Psoralea drupacea Bunge, agricultural melliferous plants – Gossypium hirsutum L. and Onobrychis Mill., weeds – Echium vulgare L., Onopordum acanthium L., Sophora L., and polleniferous plants – Hypericum L., Artemisia L., Plantago L. and Chenopodiaceae.

Effects of Leaf Hydrophilicity and Stomatal Regulation on Foliar Water Uptake Capacity of Desert Plants

Foliar water uptake (FWU) is one of the primary water sources for desert plants. Desert plants’ water uptake capacity is essential in maintaining the balance of carbon and water. However, there are few studies on FWU capacity in desert plants and the physiological and ecological characteristics that lead to differences in FWU capacity. In order to clarify FWU strategies and the influencing factors of plants in desert ecosystems, this study measured the contact angle, FWU parameters, and hydraulic parameters to explore six desert plants’ FWU capacity and the effects of leaf wettability and hydraulic parameters on FWU capacity. The results showed that all six plants had FWU capacity, among which the leaves of Nitraria sibirica Pall. and Halimodendron halodendron (Pall.) Voss had a high foliar water uptake rate (k) and high foliar water uptake accumulation (FWU storage), and the leaves of Glycyrrhiza uralensis Fisch. had a high k and low FWU storage. The leaves of Populus euphratica Oliv., Apocynum hendersonii Hook. f., and Alhagi sparsifolia Shap. had a low k and low FWU storage. Additionally, FWU capacity was mainly affected by stomatal regulation compared with leaf wettability and leaf structure. The results of this study will help to improve the understanding of the physiological and ecological adaptability of desert plants.

Nitrogen-fixing potential of Halimodendron halodendron (Pall.) Voss in arid and semi-arid areas of Iran

Nitrogen content was estimated in rhizosphere of legume Halimodendron halodendron (Pall.) Voss along with Berberis integerrima Bunge as control in sandy loam soils of arid and semi-arid areas in Middle East every 2 years (2013–2019). Lepidium sativum seed was also cultivated in soil of shrubs rhizosphere for monitoring its performance and N content. Maximum rates of 1.05% year−1 and 1.54% year−1 for soil organic nitrogen (ON) and 0.50% year−1 and 0.66% year−1 for mineral nitrogen (MN) were observed in H. halodendron rhizospheres in arid and semi-arid areas, respectively. Moreover, the highest L. sativum performance occurred in H. halodendron rhizosphere. Significant relation also was observed between N content of L. sativum and N content of shrubs rhizosphere (p < 0.02; R2 = 0.606 and 0.585 between SON and MN of soil, respectively, and L. sativum N content).

A new species of Neolycaena de Nicville, 1890 (Lepidoptera, Lycaenidae)from the Dzhungarian Gobi desert, Mongolia.

Neolycaena enkhnasani sp. n. is described from the Dzhungarian Gobi desert. The food plant is Halimodendron halodendron (Fabacea). The new species is distinguished from the related taxa known from East Kazakhstan by small size, dense gray suffusion on the hindwing underside, a delicate and partly reduced submarginal underside pattern as well as the characters of the genitalia: the shape of the valva in males and the shape of the antrum in females. Important new data about the distribution and distinctions of N. zaisana (Zhdanko, 2013) and N. balchaschensis Zhdanko, 1998 are published together with photos of the genitalia of all the three taxa.

We used a sample plot method investigation to explore the response of plant niche to the soil water and salt gradient of the Ebinur Lake Basin. Based on a study of moisture, salt content, and plant niche characteristics for arid desert areas, the changes in community composition and niche responses to soil water and salt at different gradients were analyzed. The results showed the species composition of communities had a reverse "V" pattern along the water and salt environmental factor gradient (from high to low); these phenomena indicate that the interaction of water and salt concentration was the main reason the distribution of vegetation types was restricted. The niche breadth of Populus euphratica, Reaumuria soongorica, and Haloxylon ammodendron were larger than those of Tamarix ramosissima, Alhagi sparsifolia, and Glycyrrhiza uralensis at high saltwater soil environments. The niche breadth of Nitraria schoberi and Reaumuria soongorica were larger than those of Halimodendron halodendron, Glycyrrhiza uralensis, and Halocnemum strobilaceum at moderate saltwater soil environments. The niche breadth of Haloxylon ammodendron, Karelinia capsica, and Reaumuria soongorica were larger than those of Halocnemum strobilaceum at low saltwater soil environments. These phenomena indicate that the ecological niche of a population was not only determined by soil moisture and salinity, but also the ecological characteristics of the species in the desert area. At the species level, the niche overlap of the populations with large niche breadth between other species was generally large, but the niche overlap with smaller niche breadth species was not necessarily small; however, at the community level, there was a positive correlation between niche breadth and niche overlap. These phenomena indicate that a similarity in resource latitudes increased the niche overlap between the low niche breadth species, and the relationship between them was redundant when there was a transformation of niche breadth and niche overlap from the species to the community scale. The soil water and salt gradient showed a nonlinear correlation with community ecological amplitude. The distribution pattern of high water and salt in the soil had a certain promoting effect on the niche breadth of the community, while the distribution pattern of low water and low salt had a limited effect on niche breadth. The synergistic effect of soil water and salt determined the status of species in the community and determined the direction of community succession to the positive and negative poles. 参考文献 相似文献 引证文献

Distribution regularity and habitats of Salt Tree [Halimodendron halodendron (Pall.) Voss] in Georgia (South Caucasus)

Abstract The studies have been made on the area, habitats and condition for the rare species of the flora of Georgia - Halimodendron halodendron. Its main area is the Iori plateau, including the North side territory of David Gareja monastery complex and Jangiriskhevi gorge (Karaduzi). H. halodendron is spread on the banks of ravines, terraces, plain places and slopes, elevation - approximately 530–650 msl. Growing in moist and semi-moist, as well as in dry and semidry ecotypes. Its main habitats are mesophilous and xeromesophilous shrubberies, where it is represented as a dominant-edificator. H. halodendron also invades hemixerophilous shrubberies of shibliak type. It is rarely in hemixerophilous communities of steppe. The studies on density, distribution, height and life condition of H. halodendron has been done according to the habitats. The accompanied species, main physical-geographical and phytosociological characteristics, use and level of disturbance for each habitat are given below. The conditions and vitality of H. halodendron is discussed in connection with various biotic and abiotic factors (vegetation, topography, soil, moisture and grazing).

Review of Saproxylic Beetles in Tugai Forests of Kazakhstan

AbstractIn the review, the data about the saproxylic beetles in the tugai forests of Kazakhstan is described. The main tree and shrub species related to saproxylic beetles are reported and the beetle species diversity is presented in a table. Of the species listed in the table, 36 species of saproxylic beetles are related toPopulussp. (Populus diversifoliaandP. pruinosa), 21 species toElaeagnus angustifolia, 20 species toTamarixsp., and 17 species toSalixsp. The least number of saproxylic beetles was related toFraxinus sogdiana(2 species) andHalimodendron halodendron(3 species). The author detected data about the representatives of the following families of Coleoptera: Brentidae, Bostrichidae, Buprestidae, Cerambycidae, and Curculionidae on the territory of tugai forests and the arid zone of Kazakhstan. According to the used references, the most numbered family of saproxylic beetles in the tugai forests is Buprestidae: 41 species have been known. The author found out data about 17 species of Curculionidae and 10 species of Cerambycidae. Other families have a lower number of species. It means that Buprestidae is the most studied family in the tugai forests of Kazakhstan. Further research is necessary to extend knowledge about the diversity of saproxylic beetles in the tugai forests of Kazakhstan.

Simultaneous Overexpression of the HhERF2 and PeDREB2a Genes Enhanced Tolerances to Salt and Drought in Transgenic Cotton.

A desert-grown Halimodendron halodendron ethylene-responsive element binding factor gene (HhERF2), which encodes a 245 amino acids protein containing a conserved AP2/EREBP domain, was isolated through the rapid amplification cDNA end (RACE) method. Sequence and phylogenetic analysis indicated that HhERF2 was classified into the B-2 group of ERF subfamily. Semiquantitative RT-PCR showed that HhERF2 was greatly induced by treatments with high-salt, drought and low temperature in H. halodendron seedlings. The expression vector containing HhERF2 and Populus euphratica dehydration- responsive element binding protein (PeDREB2a) genes driven by rd29A promoter was constructed and transferred into cotton (Gossypium hirsutum L.) by non-tissue culture Agrobacterium-mediated genetic transformation system. The transformation and expression of HhERF2 and PeDREB2a were identified by PCR and RT-PCR. Analyses of physiological function indicated that transgenic cottons had improved seeds germination, tolerance to drought and highsalt stresses. Agronomic evaluation in the field exhibited that transgenic lines presented a dwarf phenotype and improved further in the yield and characters. These results demonstrated that overexpressed both HhERF2 and PeDREB2a transcription factor genes in cotton induced elevated tolerance to drought and high-salt stresses.

A novel DREB transcription factor from Halimodendron halodendron leads to enhance drought and salt tolerance in Arabidopsis

A new member of the APETALA2/ethylene responsive element binding protein (AP2/EREBP) transcription factor family, HhDREB2, was isolated from Halimodendron halodendron. Based on the similarity of the AP2/ERF domain, HhDREB2 was classified into A-5 group of the DREB subfamily. The expression of HhDREB2 gene was induced by drought, high salinity, and low temperature, but not by exogenous plant hormones. Trans-activity assay demonstrated that HhDREB2 gene encodes a transcription activator. Furthermore, over-expression of HhDREB2 gene under the stress-inducible rd29A promotor in Arabidopsis resulted in enhanced tolerance to salt and drought stresses. The overall results reveal that HhDREB2 functioned as important transcription factor in regulation of stress-responsive signaling in plants and may be used for improving plant tolerance to abiotic stresses.

Phenolic Compounds from Halimodendron halodendron (Pall.) Voss and Their Antimicrobial and Antioxidant Activities

Halimodendron halodendron has been used as forage in northwestern China for a long time. Its young leaves and flowers are edible and favored by indigenous people. In this study, eleven phenolic compounds were bioassay-guided and isolated from the aerial parts of H. halodendron for the first time. They were identified by means of physicochemical and spectrometric analysis as quercetin (1), 3,5,7,8,4′-pentahydroxy-3′-methoxy flavone (2), 3-O-methylquercetin (3), 3,3′-di-O-methylquercetin (4), 3,3′-di-O-methylquercetin-7-O-β-d-glucopyranoside (5), isorhamentin-3-O-β-d-rutinoside (6), 8-O-methylretusin (7), 8-O-methylretusin-7-O-β-d-glucopyranoside (8), salicylic acid (9), p-hydroxybenzoic acid (ferulic acid) (10), and 4-hydroxy-3-methoxy cinnamic acid (11). They were sorted as flavonols (1–6), soflavones (7 and 8), and phenolic acids (9–11). Among the compounds, flanools 1–4 revealed a strong antibacterial activity with minimum inhibitory concentration (MIC) values of 50–150 μg/mL, and median inhibitory concentration (IC50) values of 26.8–125.1 μg/mL. The two isoflavones (7 and 8) showed moderate inhibitory activity on the test bacteria. Three phenolic acids (9, 10 and 11) showed strong antibacterial activity with IC50 values of 28.1–149.7 μg/mL. Antifungal activities of the compounds were similar to their antibacterial activities. All these phenolic compounds showed significant antimicrobial activity with a broad spectrum as well as antioxidant activity based on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and β-carotene-linoleic acid bleaching assays. In general, the flavonol aglycones with relatively low polarity exhibited stronger activities than the glycosides. The results suggest the potential of this plant as a source of functional food ingredients and provide support data for its utilization as forage as well.

Antimicrobial and Antioxidant Activities of the Flower Essential Oil of Halimodendron halodendron

The essential oil obtained by hydro-distillation from the flowers of Halimondendron halodendron (Leguminosae) was analyzed for its chemical composition by gas chromatography-mass spectrometry (GC-MS). Undecane (16.4%), dodecane (15.3%), tridecane (12.5%), decane (8.2%), 6,10,14-trimethyl-pentadecan-2-one (6.3%), methyl palmitate (6.0%), methyl linolenate (4.1%) and ethylcyclohexane (4.1%) were the major compounds of the thirty-five identified components of the oil. The essential oil was shown to have a broad spectrum of antimicrobial activity with MIC values ranging from 100 to 250 microg/mL, and IC50 values from 40.4 to 193.8 microg/mL. The oil also showed strong antioxidant activity, with an especially high metal chelating capacity of ferrous ions with an IC50 value of 7.4 microg/mL on ferrozine-Fe2+ complex formation.

Halimodendrin I, a new acylated triterpene glycoside from Halimodendron halodendron (Fabaceae)

Halimodendrin I, a new acylated triterpene glycoside ( 1), was isolated and chemically characterized as 3β- O-palmitoyl-28-[3′-palmitoyl-β- d-glucopyranosyl]-olean-12-en-28-oic acid from the aerial part of Halimodendron halodendron (Fabaceae) by IR, 1D and 2D NMR, HR-ESI-MS and LR-ESI-MS experiments. In addition, seven known compounds were isolated and identified as: palmitic acid, glycerol-2-linoleneate, glycerol-1,3-dilinoleneate, ferulic acid, 3- O-methylquercetin, β-sitosterol, and β-sitosterol-3- O-β- d-glucopyranoside. Nine fatty acids were identified and quantified in the saponifiable matter of the hexane extract. These fatty acids are: myristic, n-pentadecanoic, palmitoleic, palmitic, linoleic, oleic, stearic, arachidic, and behenic acids. The volatile oil was isolated by hydrodistillation (0.013%, w/w) with unpleasant smell. Twenty-seven components were identified in the oil by GC/MS.

New Triterpene Glycoside from Halimodendron halidendron (Fabaceae)

The genus Halimodendron is a monotypic genus of legume containing the single species halodendron, which is known by several common names (Caragana argentea, Halimodendron argenteum, and Robinia halodendron) [1]. The chemistry and pharmacology of this plant have not been studied before. This encouraged us to carry out the phytochemical and biological studies on the aerial parts of the plant Halimodendron halodendron. New compound (1) was isolated and chemically characterized as 3β-O-octadecanoyl-28-[3'-octadecanoyl-β-D-glucopyranosyl]-olean-12-en-28-oic acid from the aerial part of Halimodendron halodendron by UV, IR, ID and 2D NMR and HRESIMS experiments. In addition, seven known compounds were isolated and identified to be: palmetyl alcohol, Glycerol-3-linoleneate, Glycerol-1,3-dilinoleneate, ferulic acid, 3-O-methylquercetin, β-sitosterol, and β-sitosterol-3-O-β-D-glucopyranoside. Nine fatty acids were identified and quantified in the saponifiable matter of the hexane extract. The identified fatty acids were: myristic acid, n-pentadecanoic acid, palmitoleic acid, palmitic acid, linoleic acid, oleic acid, stearic acid, arachidic acid, and behenic acid. The volatile oil was isolated by hydrodistillation [0.013% (w/w)] with unpleasant smell. GC/MS analysis of the oil resulted in the identification of 27 components. The components of the oil were identified by comparing their retention time and mass fragmentation patterns with those of the available references and/or with published data as well as through GC/MS library search. This is the first report of the composition of the volatile oil of Halimodendron halodendron. The volatile oil showed moderate antimalarial activity.
