Degradation of storage proteins and formation of endopeptidases in precociously germinating peanut embryos


Proceedings of the Fourth International Workshop on Seeds: basic and applied aspects of seed biology, Angers, France, 20-24 July, 1992 Volume 2: 345-350
Degradation of storage proteins and formation of endopeptidases in precociously germinating peanut embryos
After removal of the seed coat, the immature embryos of groundnut Shanyu 71 germinated and reached 98% germination at 40 days after planting (DAP). Benzoylarginine-p-nitroanilide hydrolysing enzyme activity in the cotyledons of 60 DAP embryos increased and had 2 activity peaks after precocious germination. Endopeptidase (gelatin hydrolytic enzyme) activity in the embryos appeared at 1 d after precocious germination. The embryos began to degrade storage protein rapidly at 2 d after germination.
