Isolation and identification of casual agent of stems rot on Robinia pseudoacacia.
Abstract
Robinia pseudoacacia is an important plant with economic value and a variety of uses and is widely planted in China. Rot disease investigation found ITS branches, on campus, to pathogen separation, purification, and through the Koch#39;s law to determine ITS pathogenicity, combined with the feature of pathogen morphology and ITS, LSU, Cox Ⅱ gene phylogenetic analysis, to determine ITS classification status.
