摘要: Abstract Phakopsora pachyrhizi is a rust fungus that causes Asian soybean disease. In the nonhost plant Arabidopsis thaliana penetrated epidermis cells initiate cell death associated with mRNA transcript accumulation of PDF1.2, marker gene for defense against necrotrophic pathogens. PDF1.2 activation occurred after both inoculation A. thaliana leaves P. pachyrhizi spores and upon their treatment spore germination fluid, suggesting by secreted fungal effectors. These are likely (glyco)proteins. Together, seems to feign necrotroph pathogen during early stages infection circumvent biotrophs.
