Fen Plantation: Commons, Calvinism, and the Boundaries of Belonging in Early Modern England

AbstractIn the first half of the seventeenth century, several foreign plantations were established on wetlands drained during a wave of ambitious state-led projects across eastern England. The lines of solidarity and separation forged by this little-known episode in the history of migration pose important questions about how emergent notions of nationhood intersected with local and transnational, religious and economic communities. This article investigates the causes and consequences of the settlement of Calvinist refugees on drained commons in Hatfield Level. It argues that fen plantation expands understanding of the relationship between English agricultural improvement and imperial expansion in the British Atlantic, as migrant communities acted in the service of empires and states while forging transnational Protestant networks. As Calvinists and cultivators, however, the settlers were met with hostility in England. While the crown encouraged foreign plantation as a source of national prosperity, Laudian church authorities identified it as a threat to religious conformity, the state, and society, muddying depictions of English governors as guarantors of refugee rights. Local efforts to violently expel settlers from Hatfield Level, meanwhile, were rooted in fen commoners’ defense of customary rights, as parallel communities sought to enact rival environmental and economic models. The settler community interpreted these experiences through the lens of transnational Protestant adversity, entangling their quest for religious freedoms with their remit as fen improvers. Moving beyond dichotomous arguments about xenophobia, this article traces the transnational imaginaries, national visions, and emplaced processes through which collective identities and their sharp edges were constituted in early modern England.

Endophytic fungi: versatile partners for pest biocontrol, growth promotion, and climate change resilience in plants

Plant-associated endophytic fungi (EFs) are emerging as a promising solution to advancing modern agriculture and fostering environmental sustainability, especially in the face of climate change scenarios. These fungi, either naturally residing in plants or introduced through artificial inoculation techniques, improve agricultural production due to their various roles in protecting and supporting host plants. The majority of EFs serve as natural biocontrol agents for a variety of agricultural pests, such as insects, phytopathogens, nematodes, and weeds. Notably, EFs produce secondary metabolites, trigger immune responses, modify plant defense gene expression, confer host plant resistance and/or tolerance, and regulate pest growth, populations, and survival to combat agricultural pests. Beyond controlling pests, EFs promote optimal plant growth, development, and resilience by aiding in the synthesis of vital compounds such as phytohormones and bioactive metabolites, nutrient acquisition, and fortifying plants against environmental stresses and climatic changes. Moreover, the mostly nonpathogenic nature of EFs, coupled with their high yield potential, environmental safety, and cost effectiveness, positions them as eco-friendly and economically viable alternatives to synthetic agrochemicals amidst rapid climate change scenarios. As a result, the promising horizon of EFs in agricultural production necessitates interdisciplinary study and microbial modulation approaches to optimize symbiotic plant-EF relationships and their potential for improved productivity. This review provides current and comprehensive insights into the practical applications and multifaceted benefits of EFs in pest management, plant growth promotion, and climate change resilience for future agricultural production improvements. The analysis reveals the potential of developing EFs into innovative bioformulations such as biofertilizers, biostimulants, and biopesticides, thereby paving the way for their integration into a sustainable and more resilient future agricultural system.

An eco-friendly versatile superabsorbent hydrogel based on sodium alginate and urea for soil improvement with a synchronous chemical loading strategy

In this paper, an eco-friendly versatile superabsorbent material was designed for soil improvement, and a synchronous chemical loading strategy was proposed. In this strategy, urea not only acted as fertilizer but also acted as a crosslinker to construct an alginate network. The microstructure, chemical structure, thermal stability and composition of the obtained SA/urea hydrogel were characterized in detail. Adsorption behavior and application performance in agriculture were evaluated. The results demonstrated that urea had two different conformations in the network. The SA/urea hydrogel had abundant pore structures with excellent water absorption performance. It could not only improve the water retention capacity of soil but also release nitrogen, phosphorus and potassium elements with degradation for as long as 9 weeks. Moreover, the hydrogel could promote plant growth, increase the nutritional composition of plants and inhibit the accumulation of harmful nitrate in plants. With advantages, including biodegradability, high water absorption, controllable degradation, excellent water retention, sustained NPK release and improved plant nutrition value, the SA/urea hydrogel has great potential for soil improvement in agriculture as an eco-friendly versatile water retention agent and can be expected to extend to more fields as a novel superabsorbent material.

High-throughput soybean pods high-quality segmentation and seed-per-pod estimation for soybean plant breeding

Accurately identifying soybean pods is a crucial prerequisite for retrieving multi-phenotypic traits (such as number of pods per plant, number of seeds per pod, pod size, pod color, and pod shape). However, the traditional manual measurement approach for pod phenotype investigation is time-consuming and labor-intensive, particularly when counting the number of seeds per pod. Furthermore, existing instance segmentation methods designed for coarse-grained classification are inadequate for precise seed-per-pod estimation. To address these challenges, we modified an instance segmentation network for high-throughput soybean pods high-quality segmentation and accurate seed-per-pod estimation. We modified the classification branch of the instance segmentation network Mask Transfiner (Ke et al., 2022) by increasing the resolution of feature map of each Region of Interest (RoI) region, incorporating a dual attention mechanism, and leveraging a center loss function, named RefinePod. To overcome the limitation of scarce labeled data, we modified our synthesizing image method to automatedly generate fine-labeled multi-class soybean pods images. We then train RefinePod purely with these synthetic images. Subsequently, we evaluate the trained model on both synthetic and real test images. Experimental results demonstrate a significant improvement in the accuracy of seed-per-pod estimation achieved by RefinePod. Additionally, we conduct ablation experiments to analyze the individual contributions of each strategy employed in RefinePod. In summary, RefinePod achieves remarkable results in seed-per-pod estimation accuracy by integrating advanced techniques and leveraging synthetic images for training. Our findings highlight the potential of RefinePod for accelerating soybean phenotype investigation, enabling more efficient agricultural research and crop improvement initiatives.

Construction of a high-density genetic map for yardlong bean and identification of ANT1 as a regulator of anthocyanin biosynthesis.

Because its long, tender pods supply essential proteins, vitamins, and fibers to humans, yardlong bean (Vigna unguiculata ssp. sesquipedalis) is a commonly consumed vegetable, especially in Southeast Asia. To provide insights into the genetic bases of key agricultural traits in yardlong bean, we here created a high-density bin-map with 2084 bin markers using 514 227 SNPs from a recombinant-inbred line (RIL) population. Quantitative trait loci (QTL) mapping was carried out to identify loci associated with anthocyanin content (ANT), vitamin E content (VE), total soluble protein content (TSP), pod length (PL), hundred-seed weight (HSW), seed length and width (SL and SW, respectively), and seed coat color (SCC). In total, 20 related QTLs were isolated, explaining 7.58-56.03% of the phenotypic variation. Of these, five major QTLs (qANT5, qTSP11, qVE7, qPL3, and qSCC9) were detected in 2020, 2021, and the combined environment, explaining 11.96-56.03% of the phenotypic variation. VuANT1 was identified as a causal gene for the QTL qANT5, which regulated anthocyanin content; VuANT1 was highly expressed in immature purple pods but barely detectable in white pods. VuANT1 overexpression in tobacco leaves and yardlong bean hairy roots resulted in purple coloration as a result of anthocyanin accumulation. These findings suggested that VuANT1 was a key regulator of anthocyanin accumulation in yardlong bean. Our results lay a firm foundation for target agricultural trait improvement and clarification of the genetic mechanisms underlying agricultural traits in yardlong bean.

Using CRISPR/Cas9 Technology to Improve Crops and Address the Global Food Crisis: A Review

By developing a revolutionary method for modifying the genomes of living things, genome editing (GE) has completely changed the biological sciences. Recent years have seen the development of several technologies that make altering complex genomes possible. For agricultural crop production to be sustained and contribute to global food security, a fast and dependable method of raising yield and resilience to different environmental pressures is therefore required. The GE instruments for crop enhancement are explained in detail in this analytical research. Zinc-finger nucleases (ZFNs), transcriptional activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeats (CRISPR) are a few examples of these tools. This category also includes mega-nucleases (MNs). In particular, the most recent advancements in the use of CRISPR/Cas9 for genome editing for major agricultural improvements - like the creation of crops that are more yielding and of higher quality - are covered this paper. When this approach is put into practice, non-transgene crops with desired traits will be produced, which might lead to increased yield capacity under different environmental challenges. To increase agricultural production and guarantee food security, the CRISPR/Cas9 methodology may be used in conjunction with existing and future breeding techniques (such as omics-assisted breeding and speed breeding). The difficulties and restrictions associated with CRISPR/Cas9 have also been covered. Plant breeders and scientists doing a detailed analysis of the use of CRISPR/Cas9 to enhance crops by focusing on the desired gene will find this material to be helpful.

Mitigating soil water deficit using organic waste compost and commercial water retainer: a comparative study under semiarid conditions

Semiarid regions have particularly been confronted with climate change effects reflected by the consistent decrease of rainfall and increase of evapotranspiration. This drought stress constitutes the main constraint for agricultural production improvement, which is aggravated by the fact that strategic (field) crops are mostly grown under rainfed systems. Therefore, the objective of this field study was to improve soil water retention by the application of two conditioners namely, an organic waste compost (DS) and a synthetic water-retaining hydrogel (WS). These amendments were applied to an agricultural soil for the cultivation of fodder maize under normal and deficit irrigation regimes. Advanced analysis showed a general disruption of plant growth parameters under water stress. However, both amendments attenuated this negative effect with respect to control by improving soil water status. More precisely, the measured soil water tension at the start of the dry season was the lowest in presence of DS (48 centibars), followed by WS (61 centibars), then unamended soil (83 centibars). Besides, compost application resulted in higher moisture (13.3%), nitrogen (0.36%), and organic matter (0.56%) in soil than the synthetic hydrogel at the end of the field experiment. Soil and plant characterization highlighted the combined effect of water deficit and conditioner type. Indeed, the consistent increase of soil water content in the presence of DS and WS improved all the addressed plant parameters when compared with untreated soil. Infrared thermal imaging showed that canopy temperature was lower in presence of both amendments while dry biomass yield increased by 38% when water supply was limited. Nevertheless, the long-term sustainability of the soil system appears to be better maintained in the presence of the organic waste compost. The latter has the added advantage of improving soil fertility in contrast to inert polymers.

Does the rural housing land system reform model meeting the needs of farmers improve the welfare of farmers?

The rural land system reform (RLSR) is inseparable from the protection of farmers' rights and profits. The success or failure of the system reform determines the value embodiment of the farmers' subject position. Under the background of continuously promoting the RLSR in China, combining the farmers' demands and welfare change, this study reveals the practice and process of rural housing land system reform (RHLSR) and puts forward three theory hypotheses. Then, four kinds of RHLSR mode are designed based on the outer edge-kernel system theory and Maslow demand theory. Finally, using fuzzy mathematical evaluation and a structure equation model, this study depicts the implementation process and effect of 20 typical cases and puts forward corresponding policy enlightenment. Results show that (1) due to the influence of the system, the RHLSR mode is diversified; the RHLSR mode that conforms to farmers' needs is also conducive to improving farmers' welfare level. (2) The correlation between farmers' living status and welfare level is the highest in the RHLSR process, while the degree of social participation is the lowest. (3) The land investment mode (LIM) has the best effect on the improvement of farmers’ welfare (FW) level, followed by the monetary compensation mode (MCM), and the asset replacement mode (ARM). Meanwhile, the use of land to ensure the life of the aged mode (ULELAM) has the lowest effect. These findings indicate that the government should adhere to the concept of people first, combining the welfare needs of farmers step-by-step. Those needs should be prioritized and optimized appropriately, according to the time and household, so as to realize a better tilt of land policy dividend towards farmers.

Agricultural Land Rights Confirmation, Clan Network, and Farmers’ Investment in Production and Operation

This study is based on micro-survey data on rural household transfers in China. This study uses a multiple linear regression model (to analyze the relationship between variables), an instrumental variable model (to solve potential endogenous problems), and an intermediary effect model to explore the impact of farmland rights confirmation and clan network on farmers’ investment in production and operation and the relationship between clan network confirmation of farmland rights and farmer household investment. The research shows that: (1) The confirmation of farmland rights in China substantially bolsters farmers’ investments in agricultural production and operation. It serves as a secure foundation for land property rights, elevating farmers’ confidence and significantly contributing to the growth of rural economies and the improvement of farmers’ income levels in the Chinese context. (2) In the Chinese context, the existence of clan networks exerts a discernible adverse influence on farmers’ investment decisions in agricultural production and operation. This is primarily attributable to the restricted flow of information within these networks, the enforcement of stringent social norms, and the prevalence of risk-averse attitudes. These factors collectively act as barriers, dampening farmers’ enthusiasm for investment and impeding effective decision-making. (3) Importantly, the confirmation of agricultural land rights in China serves as a counterbalance to the inhibitory effects of clan networks. It achieves this by mitigating information asymmetry and reducing cooperation risks. This proactive approach not only promotes but also facilitates farmers’ investments in agricultural production and operation within the Chinese context. Consequently, land rights confirmation emerges as a key driver of increased rural investments in China. This study conducts in-depth research on the impact of farmland ownership confirmation and clan networks on farmers’ investment behavior and the mechanism of action, which provides a useful reference for formulating relevant policies, such as increasing the authority of cultivated land, promoting the modernization of clan networks, cultivating modern management capabilities, etc.
