Abstract
Methyl jasmonate inhibited the harpin-induced defense responses such as cell death, H2O2 generation and gene expression encoding phenylalanine ammonia-lyase in tobacco suspension cultured BY-2 cells. These results suggest that MeJA may act as an endogenous suppressor for plant defense response including hypersensitive reaction.
摘要
茉莉酸甲酯抑制了烟草悬浮培养的BY-2细胞中由harpin诱导的防御反应，如细胞死亡、H2O2产生以及编码苯丙氨酸解氨酶的基因表达。这些结果表明，茉莉酸甲酯可能作为一种内源性抑制剂，抑制包括过敏反应在内的植物防御反应。
