Abstract d -allose is one kind of rare sugar and its biological functions and metabolic pathways in several organisms have been reported, but its function in plants’ resistance has not been well understood. In this research, we analyzed the function of d -allose in plant immunity in tomato. The plants which were pretreated with 5 mM d -allose increased the resistance to Botrytis cinerea and Pseudomonas syringae pv. tomato (Pst) DC3000 compared with the plants treated with water, with lighter symptom. The d -allose treatment induced the resistance to B. cinerea and Pst DC3000 maybe through regulating reactive oxygen species (ROS) accumulation and the expression levels of defense-related genes.

D-阿洛糖是番茄诱导性植物免疫的关键调节剂

摘要 d-阿洛糖是一种稀有糖类，其在多种生物体中的生物学功能和代谢途径已有报道，但其在植物抗性中的作用尚不清楚。本研究分析了d-阿洛糖在番茄植物免疫中的作用。用 5 mM d-阿洛糖预处理的植物增加了对灰葡萄孢和丁香假单胞菌 pv 的抗性。番茄 (Pst) DC3000 与用水处理的植物相比，症状较轻。d-allose 处理可能通过调节活性氧 (ROS) 积累和防御相关基因的表达水平来诱导对 B. cinerea 和 Pst DC3000 的抗性。
