One of the biggest challenges of 21st century is feeding the growing human population. Plant pathogens cause devastating yield losses in staple crops and pose a serious threat to global food security. According to recent reports, plant pathogens cause crop losses that if alleviated would feed at least 700 million people. To prevent crop loses due to pathogens, we have to understand plant-microbe interactions at molecular and systems level. To facilitate plant colonization these deadly microbes evolved unique infection strategies. They form specialized infection cells that involve tightly controlled spatiotemporal repolarization events. Additionally, pathogens also induce extensive membrane remodeling within plant tissues. They initiate plant infection via invagination of plant plasma membrane and reorient cellular resources to these infection cells. They can occupy up to 80% of plant cell volume without inducing any immune response. We have limited knowledge on the molecular details of infection cell morphogenesis and cellular reprogramming during plant infection. I will present our recent results on rice blast and Irish potato famine pathogen and propose research questions that can be answered using mathematical modeling.
