Molecular biological studies on mechanisms involved in pathogenicity of citrus pathogens

摘要

Apple stem grooving virus (ASGV) (formerly citrus tatter leaf virus), the type species of the genus Capillovirus in the family Flexiviridae, is the causal agent of citrus bud-union crease syndrome and apple top-working disease. Xanthomonas axonopodis pv. citri (Xac) causes citrus canker symptoms including cell hypertrophy and abnormal division leading to eventual cell death. Here we elucidated the mechanism for viral gene expression that is responsible for ASGV virulence, the plant factors essential for symptom development in response to Xac, and a plant protein candidate involved in both ASGV and Xac pathogenicity during the host–pathogen interactions.
