Nutrients In Different Tissues Research Articles

Metabolic Changes in Different Tissues of Garlic Plant during Growth.

The accumulation, distribution, and transportation of nutrients in different tissues of garlic during growth are unclear. Thereby, five tissues (leaf, pseudostem, bulb wrapper, clove skin, and clove) collected at 7 weeks were subjected to metabolomics analysis. A total of 84 biomarkers were identified during garlic plant growth. Most organosulfur compounds, amino acids, and dipeptides were upregulated in the clove, while a reversed trend was observed in other tissues. In addition, nucleotides and alkaloids increased because of senescence in the last 2 weeks except for the clove. The results also indicated that the garlic plant at an early stage is an ideal vegetable that is rich in nutrients. When the leaves began to wither, most nutrients were transported from other tissues to cloves, and the content of 7 total flavor precursors and 20 total amino acids in the clove increased by 113% and 65% after week 5, respectively. Therefore, delayed harvest may improve the nutritional quality of garlic bulbs.

Accumulation and translocation of copper in Cu-polluted sierozem in northwest China

ABSTRACT Studies on subsequent effects of Cu pollution on mineral nutrients uptake in different tissues of crops grown in sierozem are limited. A pot experiment was conducted to reveal the effects of exogenous Cu on the accumulation and translocation of Cu and the interaction with nutrients in different tissues of wheat in Cu-polluted sierozem in northwest China. Results showed that the average concentration of Cu in different tissues of wheat was roots > stems and leaves > grains > shells. The bioaccumulation factor (BCF) of Cu in different parts of wheat was roots > stems and leaves > grains > shells. There was a weak translocation of Cu from sierozem to tops of wheat. Furthermore, the translocation ability of Cu from roots to tops of wheat was increasingly weak with increasing Cu stresses. Micronutrients (Fe, Mn and Ca) distribution in different wheat tissues indicated that uptake and upward translocation of these kinds of micronutrients could be affected by high soil Cu concentration. The addition of Cu in sierozem promoted the Mn absorption in wheat tissues, which may also be helpful to solve the lack of Mn in wheat caused by the Cu shortage in sierozem.

Profiling selected phytochemicals and nutrients in different tissues of the multipurpose tree Moringa oleifera L., grown in Ghana

The purpose of this new study was to determine the types and levels of major phytochemicals (non-nutrients) and nutrients in the different tissues from vegetative and flowering Moringa oleifera L. an important multipurpose crop. Rhamnose and acetyl-rhamnose-substituted glucosinolates were found in all of the M. oleifera tissues with different profiles depending on the tissue. In addition the tissues of M. oleifera had a relatively complex flavonoid profile consisting of glucosides, rutinosides, malonylglucosides and traces of acetylglucosides of kaempferol, quercetin and isorhamnetin. Fatty acid profiling of the different tissues showed that leaves were rich in palmitic (16:0) and linolenic (18:3) acid whereas seeds were predominated by oleic acid (18:1). Roots were rich in palmitic and oleic acid, whereas stems and twigs predominately contained palmitic acid. Potassium, magnesium and calcium were the predominant minerals in all of the tissues. Low levels of selenium were detected only in whole seeds.
