The leguminous tree Sophora japonica contains a family of closely related, but distinct, lectins. Different members of this family are independently expressed in seeds, leaves, and bark (CN Hankins, J Kindinger, LM Shannon 1987 Plant Physiol 83: 825-829; 1988 Plant Physiol 86: 67-10). The inter-, and intracellular distribution of the bark and leaf lectins was studied by indirect postembedding i...

The functional transition of glyoxysomes to leaf peroxisomes occurs during greening of germinating pumpkin cotyledons (Cucurbita sp. Amakuri Nankin). The immunocytochemical protein A-gold method was employed in the analysis of the transition using glyoxysomal specific citrate synthase immunoglobulin G and leaf peroxisomal specific glycolate oxidase immunoglobulin G. The labeling density of citr...

Background: Leaf protein concentrate (LPC) is a cheap and feasible source of high-quality protein. Researchers found the quality LPC similar to first-class food. Tobacco protein-rich leaf but contains high amount nicotine. According studies obtained from tobacco leaves nicotine-free also useful gaining weight in malnourished rats. Methods: Fresh were blended with distilled water different ratio...

Leaf senescence is a developmentally programmed cell death process that constitutes the final step of leaf development and involves the extensive reprogramming of gene expression. Despite the importance of senescence in plants, the underlying regulatory mechanisms are not well understood. This study reports the isolation and functional analysis of RAV1, which encodes a RAV family transcription ...

The maize (Zea mays) leaf is a valuable system to study the sucrose import to sucrose export transition at the cellular level. Rapidly growing and fully heterotrophic cells in the basal part of the young leaf showed a high sucrose synthase (SS) activity. Leaf SS has been purified to homogeneity. By comparison with purified kernel SS isozymes, the leaf SS has been identified as SS(2). SS(1) prot...

in a pot experiment the effect of water stress on the proteins and proline amino acid content of jam, kurosh, pirooz chickpea cultivars (cicer arientinum) were evaluated using a complete block design with factorial treatments inducing cultivars and watering periods, three, six and nine day intervals in three replications. soluble protein and free proline content of the leaf and the root were me...

postharvest senescence is a major factor, limiting the marketing of many species of cut flowers, including roses. considerable efforts have been devoted to developing postharvest treatments to lengthen the extend of the marketing period. the purpose of this study was to determine the most suitable nitric oxide, and thidiazuron concentrations to increase the antioxidant activity as well as prote...
