%X Mungbean (Vigna radiate L.), a chilling sensitive plant species, was used in this study. Seeds were germinated at 28 C in the dark for 32 H before cold treatment. The seedlings were chilled at 4 C for various durations. Growth, respiration rate, protein synthetic activity, cellular leakages and succinate dehydrogenase activity in isolated mitochondria were then determined.
Chilling at r C suppressed seedling growth, increased solute leakages, suppressed succinate dehydrogenase activity in isolated mitochondria, inhibited general protein synthesis and induced the synthesis of a set of proteins termed chilling-induced proteins. The molecular weights of these chilling-induced proteins were110, 88, 78, 69, 58, 48, 38, 14, 12.5 and 10.5Kd were the major chilling-induced proteins of mungbean seedlings. These chilling-induced proteins were different from the heat shock proteins of mungbean seedlings.
