Pathogen challenge to Arabidopsis cotyledons sets sustained upregulation of a WRKY gene and defense priming at newly formed rosette leaves

摘要

Pathogen recognition by plants can have promoting effects on the degree of disease resistance in subsequent infections. We wondered whether seedlings bearing cotyledons challenged with avirulent pathogens can induce enhanced disease resistance in newly formed rosette leaves (NFRLs) against virulent pathogens. The purpose of this study is to examine disease resistance in NFRLs of plants with cotyledons challenged with an avirulent pathogen.
