摘要: Plant-microbe interactions feature complex signal interplay between pathogens and their hosts. Phytophthora species comprise a destructive group of fungus-like plant pathogens, collectively affecting wide range plants important to agriculture natural ecosystems. Despite the availability genome sequences both hosts microbes, little is known about them during infection. In particular, accurate descriptions coordinate relationships host microbe transcriptional programs are lacking. Here, we explore molecular interaction hemi-biotrophic broad pathogen capsici tomato. Infection assays use composite microarray allowed us unveil distinct changes in P. tomato transcriptomes, associated with biotrophy subsequent switch necrotrophy. These included two early infection necrotrophy transition that may contribute completion lifecycle Our results suggest dynamic but highly regulated programming underpin disease hemi-biotrophy. Dynamic expression effector-coding genes factors involved immunity, suggests modulation immune signaling by pathogen. With new unprecedented detail on reprogramming, can now drive host-microbe basic processes lifestyles. Deliberate alteration lifestyle-associated allow prevention or perhaps disruption cycles limit damage caused epidemics.
