Abstract

Salicylic acid (SA) induces the mechanism of the plant defence and plays a role in plant -pathogen interactions. Following the nematode infection, effects of SA treatment on plant weights and the expression of pathogen related gene have not been fully understood. The present study was aimed to determine the effects of SA treatment on the expression Pathogenesis related 1 gene (PR1 gene) and alteration on plant parameters in tomatoes (Solanum lycopersicum). Plant seedlings were dripped within the SA solution. The expression of PR1 gene achieved using RT-PCR at 1, 3, 7, 14, 21-days post infection (dpi) with Meloidogyne incognita. Upregulation of PR1 gene was determined in early (1 dpi) and late (21 dpi). SA treatment and nematode infection altered plant parameters. SA treatment increased the plant defence mechanisms in tomato against Meloidogyne incognita.

发病机理相关1（PR1）基因在番茄中的表达及水杨酸的暴露对宿主-根结线虫互作的影响

摘要

水杨酸（SA）诱导植物防御机制，并在植物与病原体的相互作用中发挥作用。线虫感染后，尚未完全了解SA处理对植物重量和病原体相关基因表达的影响。本研究的目的是确定SA处理对表达的影响发病机制相关的1个基因（PR1基因）和变更对西红柿植物参数（番茄）。将植物幼苗滴入SA溶液中。PR1基因的表达是通过RT-PCR在甲型根结线虫感染后1，3、7、14、21天（dpi）实现的。PR1的上调在早期（1 dpi）和晚期（21 dpi）确定基因。SA处理和线虫感染改变了植物参数。SA处理提高了番茄对根结线虫的植物防御机制。
