Identification of genes related to tipburn resistance in Chinese cabbage and preliminary exploration of its molecular mechanism.

ABSTRACT:

Background

Tipburn, also known as leaf tip necrosis, is a severe issue in Chinese cabbage production. One known cause is that plants are unable to provide adequate Ca²⁺ to rapidly expanding leaves. Bacterial infection is also a contributing factor. Different cultivars have varying degrees of tolerance to tipburn. Two inbred lines of Chinese cabbage were employed as resources in this research.

Results

We determined that the inbred line 'J39290' was the tipburn resistant material and the inbred line 'J95822' was the tipburn sensitive material based on the severity of tipburn, and the integrity of cell membrane structure. Ca²⁺ concentration measurements revealed no significant difference in Ca²⁺ concentration between the two materials inner leav
