Leaf protein can be obtained cost-efficiently by alkaline extraction, but overuse of chemicals and low quality of (denatured) protein limits its application. The research objective was to investigate how alkali aids protein extraction of green tea leaf residue, and use these results for further improvements in alkaline protein biorefinery. Protein extraction yield was studied for correlation to...

This present study investigated the potential of Morinda citrifolia leaf aqueous extract to induce osteogenic differentiation and matrix mineralization of human periodontal ligament (hPDL) cells. Human periodontal ligament cells were cultured in complete medium, ascorbic acid with β-glycerophosphate, or Morinda citrifolia leaf aqueous extract. Morinda citrifolia leaf aqueous extract significant...

Many tissues which have been investigated have at least two malate dehydrogenase isoenzymes. One is an organelle form localized in mitochondrial fractions whereas the other does not appear to associate with organelles sedimenting after high speed centrifugation (17). Spinach leaf tissue has an additional malate dehydrogenase isoenzyme localized in the peroxisome or leaf microbody fraction (12, ...

BACKGROUND AND AIMS The hypothesis was tested that pectin content and methylation degree participate in regulation of cell wall mechanical properties and in this way may affect tissue growth and freezing resistance over the course of plant cold acclimation and de-acclimation. METHODS Experiments were carried on the leaves of two double-haploid lines of winter oil-seed rape (Brassica napus sub...

Plant morphological changes mediated by growth conditions are linked to changes in host preference of herbivores. Understanding how these morphological changes inßuence herbivore feeding is critical in the interpretationof results of host evaluationof candidateweedbiocontrol agents in quarantine and improvement of the evaluation system. We determined the effect of plant growth conditions on lea...

Photosynthetic processes in Zostera japonica, an upper intertidal species, were found to be more severely affected by desiccation than Z. marina, a lower intertidal and subtidal species, at comparable levels of tissue water content. The data indicate that photosynthetic responses to desiccation at the level of the individual leaf are insufficient to explain observed patterns of intertidal seagr...

Leaf internal, or mesophyll, conductance to CO(2) (g(m)) is a significant and variable limitation of photosynthesis that also affects leaf transpiration efficiency (TE). Genotypic variation in g(m) and the effect of g(m) on TE were assessed in six barley genotypes (four Hordeum vulgare and two H. bulbosum). Significant variation in g(m) was found between genotypes, and was correlated with photo...

In previous studies, we have shown the relaxatory effect of grape leaf (Vitis vinifera) extract on isolated ileum, uterus and aorta. In rat aorta it was revealed that the NO and endothelium are involved in the relaxation induced by grape leaf extract. The aim of present study was to investigate the effect of the Vitis vinifera leaf hydroalcoholic extract (VLHE) on rat trachea precontracted by A...

Cumin, Cuminum cyminum L., is the king of spices with a plethora of natural compounds with pharmacological features. Drought stress is a well-known factor that influences the production of some metabolites. We studied the impact of drought stress on gene expression and metabolite content in flower and leaf tissue organs of two ecotypes, Taybad and Ardakan populations. Plants were imposed into t...
