The carbohydrate content of barley (Hordeum vulgare L.) leaves was measured over a 24-hour cycle. Nonstructural carbohydrate accumulation was linear after the 1st hour of light, whereas utilization in the dark was fast initially and slowed as stored reserves were depleted. Sucrose was the most
Starch is the most abundant storage carbohydrate produced in plants. The initiation of transitory starch synthesis and degradation in plastids depends mainly on diurnal cycle, post-translational regulation of enzyme activity and starch phosphorylation. For the proper structure of starch granule the
Acquisition of cell identity requires communication among neighboring cells. To dissect the genetic pathways regulating cell signaling in later leaf development, a screen was performed to identify mutants with chloroplast pigmentation sectors that violate cell lineage boundaries in maize (Zea mays)
The rate of net CO(2) assimilation of mature wheat (Triticum aestivum L.) leaves in ambient air (21% O(2), 340 microbars CO(2)) declined with time of illumination at temperatures lower than 25 degrees C, but not at higher temperatures, and the rate of decline increased when maintained in air with
Leaf respiration is a major metabolic process that drives energy production and growth. Earlier works in this field were focused on the measurement of respiration rates in relation to carbohydrate content, photosynthesis, enzymatic activities or nitrogen content. Recently, several studies have shed
Three new hexose derivatives (1-3), together with two known ones (4,5), were isolated from the leaves of Sauropus rostratus. The structures of new compounds were elucidated on the basis of the spectroscopic methods including 1D and 2D NMR (HSQC, (1)H-(1)H COSY, HMBC and NOESY) and HR-MS analyses.
BACKGROUND
Tea (Camellia sinensis L.), contains high levels of secondary metabolic products with both commercial and medicinal value. At present, most cultivated tea plant have green leaves; although tea plants with purple leaves exist, their supply is inadequate. During leaf growth and maturation,
BACKGROUND
Myrica esculenta (Family: Myricaceae) commonly known as Kaiphala or Katphala is a widely used medicinal plant in Ayurveda. In spite of its numerous medicinal attributes, no published work is available till date on pharmacognostical characterization and HPTLC analysis of its
The effect of wilting on proline synthesis, proline oxidation, and protein synthesis-all of which contribute to proline accumulation-was determined in nonstarved barley (Hordeum vulgare L.) leaves. Nonstarved leaves were from plants previously in the light for 24 hours and starved leaves were from
The polyol myo-inositol constitutes 10-20% of soluble carbohydrates in mature leaves of Actinidia deliciosa (A.Chev.) C.F. Liang et A.R. Ferguson var. deliciosa 'Hayward' and A. arguta (Sieb. et Zucc.) Planch. ex Miq. var. arguta. In contrast with other non-structural carbohydrates, myo-inositol
The oomycete Plasmopara viticola is responsible for downy mildew, a severe grapevine disease. In infected grapevine leaves, we have observed an abnormal starch accumulation at the end of the dark period, suggesting modifications in starch metabolism. Therefore, several complementary approaches,
OBJECTIVE
To investigate nutrient composition in moringa leaves and compare with those of kale (Brassica carinata) and Swiss chard (Beta vulgaris).
METHODS
Laboratory based study, nutrient composition of fresh and cooked leaves of M. stenopetala were analyzed.
METHODS
Gama-Gofa, south-western
Whole-plant carbohydrate partitioning involves the assimilation of carbon in leaves and its translocation to nonphotosynthetic tissues. This process is fundamental to plant growth and development, but its regulation is poorly understood. To identify genes controlling carbohydrate partitioning, we
