Powdery mildew, caused by Uncinula necator Burr, is one of the most seriously damaging diseases of grapevine all over the world. To gain the novel gene and investigate the resistance mechanism in Chinese Wild Vitis pseudoreticulata clone Baihe-35-1, mRNA differential display was employed to study
An 888-bp full-length ascorbate peroxidase (APX) complementary DNA (cDNA) gene was cloned from Anthurium andraeanum, and designated as AnAPX. It contains a 110-bp 5'-noncoding region, a 28-bp 3'-noncoding region, and a 750-bp open reading frame (ORF). This protein is hydrophilic with an aliphatic
H2O2 has been found to be required for the activity of the main microbial enzymes responsible for lignin oxidative cleavage, peroxidases. Along with other small radicals, it is implicated in the early attack of plant biomass by fungi. Among the few extracellular H2O2-generating enzymes known are the
