主 题：fruit pathogen strategies
摘 要：Infections by the fungus Monilinia laxa,the main cause of brown rot in Europe,result in considerable losses of stone ***,we present a comprehensive transcriptomic approach to unravel strategies deployed by nectarine fruit and *** during their *** used ***-inoculated immature and mature fruit,which was resistant and susceptible to brown rot,respectively,to perform a dual RNA-Seq *** immature fruit,host responses,pathogen biomass,and pathogen transcriptional activity peaked at 14–24 h post inoculation(hpi),at which point *** appeared to switch its transcriptional response to either quiescence or *** fruit experienced an exponential increase in host and pathogen activity beginning at 6 *** analyses in both host and pathogen highlighted differences in stage-dependent *** example,in immature fruit,*** unsuccessfully employed carbohydrate-active enzymes(CAZymes)for penetration,which the fruit was able to combat with tightly regulated hormone responses and an oxidative burst that challenged the pathogen’s survival at later time *** contrast,in mature fruit,*** was more dependent on proteolytic effectors than CAZymes,and was able to invest in filamentous growth early during the *** analyses of mature fruit infected with *** indicated that,while jasmonic acid activity was likely useful for defense,high ethylene activity may have promoted susceptibility through the induction of ripening ***,we identified *** genes that were highly induced in both quiescent and active infections and may serve as targets for control of brown rot.
