Identification and functional analysis of glyoxal oxidase gene from rubber tree anthracnose

Abstract

Hevea brasiliensis Muell is the primary source of natural rubber production. Rubber tree anthracnose caused by hemi-biotrophic phytopathogenic fungi Colletotrichum species is among the most serious leaf diseases affecting rubber tree plantations and limiting cultivation (Liu et al. 2018;Song et al. 2022). This disease frequently occurs in leafing in early spring, responsible for the repeated defoliation of rubber trees and causing huge economic losses (Liu et al. 2018). The C. gloeosporioides species complexes and C. acutatum species complexes are causal agents of rubber tree anthracnose on rubber trees worldwide.
