Abstract
In this paper,the effect of drought stress on drought-induced protein in leaves of Chenopodium album L.is studied using the SDS-PAGE method.The results show that,on the tenth day of drought stress,the polypeptides with molecular weights of approximate 110.3 KD,103.9 KD,24.8KD,22.7KD and 21.0KD on SDS-PAGE gel were remarkably increased under moderate drought stress,and the polypeptides with molecular weights of approximate 22.7KD and 21.0KD were remarkably increased under severe drought stress,but were much lower than that under moderate drought stress;on the fifteenth day of drought stress,the polypeptides with molecular weights of approximate 110.3 KD,103.9 KD,26.4KD,24.8KD,22.7KD,21.0KD and 19.2KD were remarkably increased under moderate drought stress.It is revealed that the expression of gene which is more adaptable to drought stress and more resistant to drought is induced,or the expression of some gene is increased and results in the appearance of some new protein,or the content of some protein is increased and the drought-resistant capacity of Chenopodium album L.is enhanced.
