Evaluation of Indira Soya-9 [Glycine Max (L.) Merrill] for protein profile variation and desiccation tolerance during germination
Keywords:Protein, quantitative, germination, ocular marker, desiccation tolerance
AbstractIndra soya-9 Glycine max. (L.) Merr. a variety of soybean seed rich in protein, harvested in Chhattisgarh region of India is one of the main cash crops. Physiochemical changes in developing seeds of Indra soya-9 establish relationship between the germination and desiccation tolerance. The quantitative and qualitative profiling of total, soluble and heat-stable proteins was assessed through Ocular comparison and protein extraction from axes and cotyledons at various stages of seed development. The study of variety Indra soya-9 reveals gradual changes of pod colour synchronized to proteins availability. Total protein declined slighty but soluble protein content rose between first two stages compared with heat stable protein which increased gradually from Stage -I to Stage-IV both in the axes and cotyledons. Desiccation tolerance appears to be linked with change in drying induced proteins. Further, these change the water content of the seed which marks the transition from development to germinability.
