HpaG_(Xooc)及其功能片段对绿茶产量和生化品质的影响

The Effects of HpaG_(Xooc) and Its Functional Fragment HpaG_(1—94) on Production and Quality of Green Tea

将水稻细条斑病菌HpaGXooc的1—94位氨基酸序列分离,得到片段HpaG1—94.与HpaGXooc相比,HpaG1—94促进作物生长的活性显著提高.在茶园施用HpaGXooc和HpaG1—94后,不仅能促进绿茶新叶生长,提高茶叶产量,而且可以提高叶片中儿茶酚的含量,改善绿茶生化品质.与对照相比,HpaGXooc和HpaG1—94处理的小区茶叶产量分别提高37.3%和50.5%,叶片儿茶酚含量提高64.5%和72.7%.可见,HpaGXooc,尤其是功能片段HpaG1—94,在绿茶无公害生产中可望发挥重要作用.

HpaGXooc is a harpin protein from Xanthomonas oryzae pv.oryzicola.The functional fragment HpaG1—94 which contains the 1—94 site amino acid sequence of HpaGXooc is separated.The two proteins can markedly increas growth and yield of green tea(Camellia sinensis),and increas leaf contents of tea catechols.When tea shrubs are treated with HpaGXooc and HpaG1—94 compared to the control,green tea yields are over 37.3% and 50.5% greater,and leaf catechols are increased by more than 64.5% and 72.7%,respectively.The r...
