主 题：Lesion mimic mutant ROS accumulation antioxidant enzymes barley
摘 要：A barley mutant,194,was observed to exhibit a leaf spot phenotype over the whole course of its growing *** this study,the phenotype and antioxidant competence were studied in the lesion mimic mutant *** height was slightly higher in mutant 194 than in the wild type(WT).In addition,leaf spot per plant in mutant 194 was significantly higher than in *** competence,as indicated by reactive oxygen species(ROS)accumulation,antioxidant enzyme activity,and the expression of antioxidant enzyme-encoding genes was also assessed in mutant *** to the WT,mutant 194 displayed a relatively higher accumulation of ROS,accompanied by lower activities of some antioxidant enzymes and downregulation of antioxidant enzyme-encoding *** demonstrated reduced antioxidant competence in mutant *** results suggested that this lower antioxidant competence of mutant 194 could lead to the accumulation of excessive *** excess of ROS could induce programmed cell death and has the potential to promote disease resistance in mutant 194.
