摘要
作为真菌细胞壁的主要成分之一的壳寡糖 (Oligo GlcNAc)能够诱导水稻悬浮细胞和幼叶细胞发生过敏性死亡 ,并伴有H2 O2 的积累。以 1μg·mL-1壳寡糖处理水稻悬浮细胞 12h后细胞明显死亡 ;诱导水稻幼叶细胞出现明显的死亡所需壳寡糖浓度为 5 μg·mL-1。以壳寡糖处理的水稻抗稻瘟病性也明显增强。
As one of the most components of fungal cell walls, Oligo GlcNAc could induce hypersensitive cell death in rice suspension cells and seedling leaves, and H 2O 2 accumulation simultaneously. In incubation with 1 μg·mL -1 of Oligo GlcNAc, detectable cell death appeared after 12 h in rice suspension cells, which appeared on rice seedling leaves induced by 5 μg·mL -1 of Oligo GlcNAc. And the disease resistance in rice to Magnaporthe grisea was enhanced strongly.
