Abstract

AbstractBroad-spectrum resistance has great values for crop breeding. However, its mechanisms are largely unknown. Here, we report the cloning of a maizeNLRgene,RppK, for resistance against southern corn rust (SCR) and its cognateAvrgene,AvrRppK, fromPuccinia polysora(the causal pathogen of SCR). TheAvrRppKgene has no sequence variation in all examined isolates. It has high expression level during infection and can suppress pattern-triggered immunity (PTI). Further, the introgression ofRppKinto maize inbred lines and hybrids enhances resistance against multiple isolates ofP. polysora, thereby increasing yield in the presence of SCR. Together, we show thatRppKis involved in resistance against multipleP. polysoraisolates and it can recognize AvrRppK, which is broadly distributed and conserved inP. polysoraisolates.
