Glycine max; soybeans; flowering; plant proteins; molecular cloning; gene expression regulation; photoperiod; amino acid sequences
Abstract:
... Soybean is a typical short-day crop, and its photoperiodic response of flowering is critical to its yield. This phenomenon was well studied during the last century, but the molecular mechanism governing it is unknown. The clock-gene homologs, GmLCL1 and GmLCL2 (Glycine max LHY/CCA1 Like 1 and 2) and GmTOC1 (Glycine max TOC1) were cloned from Glycine max L. KN18, and their expression patterns were ...

Abstract:
... The regulation of endogenous level of ascorbic acid in soybean (Glycine max L. Merrill) by cryptic red light signal (CRS) was studied. CRS is a cellular signal induced by red light pre-irradiation that amplifies the action of phytochrome, and is known to enhance anthocyanin synthesis in sorghum. A phytochrome-enhanced endogenous level of ascorbic acid in soybean seedlings was amplified by CRS. The ...

Abstract:
... Exogenous melatonin was applied to etiolated seedlings of wild leaf mustard (Brassica juncea) and the effect on root growth and endogenous indole-3-acetic acid (IAA) levels determined. The results show that 0.1 μM melatonin has a stimulatory effect on root growth, while 100 μM is inhibitory. Furthermore, the stimulatory effect was only detectable in young seedlings (2-d old). Older seedlings (4-d ...

Abstract:
... Farmers' seeds are most often lumped together in one broad category called 'landraces'. But such a category covers variety types that reflect different levels of farmer involvement. Those differences matters when we discuss such issues as genetic erosion, on-farm conservation and seed related policies. The term landrace can be traced to the time when 'modern' varieties of cereals were introduced t ...
