Phakopsora pachyrhizi triggers the jasmonate signaling pathway during compatible interaction in soybean and GmbZIP89 plays a role of major component in the pathway

摘要: The biotrophic fungus Phakopsora pachyrhizi is currently the major pathogen affecting soybean production worldwide. It has already been suggested for non-host interaction between P. and Arabidopsis thaliana that in early infection induces jasmonic acid (JA) pathway to detriment of salicylic (SA) as a mechanism establishment infection. In this study, we verified might also be occurring during compatible (Glycine max L. Merril). was demonstrated triggers JA late stages susceptible cultivar. expression GmbZIP89 induced biphasic profile, similarly other responsive genes, which indicates new marker gene signaling pathway. Additionally, plants silenced (iGmZIP89) by virus-induced silencing (VIGS) approach present lower severity higher pathogenesis related protein 1 (PR1). disease showed iGmbZIP89 became more resistant These data corroborate hypothesis may resistance negative regulator. conclusion, mimics necrotrophic activates JA/ET soybean. possible suppose its direct penetration on epidermal cells or fungal effectors modulate target genes aiming activation inhibition SA defense.
