The infection modes of microbes in hosts can be reversible and can range from pathogenic to mutualistic, depending on the environmental conditions. The plant-associated fungus Colletotrichum tofieldiae (Ct) has been shown to promote primary root growth and increase shoot fresh weight of Arabidopsis in…

Many different pathogens attack plants, and many genes have been identified that confer pathogen-specific resistance.  In a recent study, Hao et al. identified a signaling cascade that regulates broad-spectrum disease resistance. This pathway is composed of a rice ubiquitin ligase OsPUB73, a VQ motif-containing…

Tolerance against a pathogen can be achieved by either overexpressing a resistance-related gene, or removing a susceptibility-related gene. Overexpression of defense-related genes generally comes with side effects such as decreased growth and yield. On the other hand, a susceptibility factor might have…

The basic requirements for plant growth are water, nutrients, and light. There are many other factors contributing to plant growth, including the interactions between plants and soil microorganisms. Soil microorganisms produce a large array of volatiles that can affect root architecture (e.g., some volatiles…

Plantae Presents - Sophien Kamoun and Phil Carella Recorded Wednesday September 16 10am EDT, 4pm CET Sophien Kamoun: Evolutionary dynamics of NLR immune receptors in plants Sophien Kamoun is senior scientist at the Sainsbury Laboratory and professor of biology at the University of East Anglia.…

Autophagy is a regulated process whereby select cytoplasmic components are degraded. It is involved in a variety of biological processes, including defense against pathogens. As such, plant pathogens have evolved mechanisms to target host autophagy machinery to gain virulence. However, we still lack…

The plant apoplast is a sea of immune-related proteins that facilitate robust defense against pathogens. Rcr3 is a tomato secreted apoplastic protease that contributes to both basal defense and gene-for-gene resistance against pathogens. Rcr3 is activated by the cleavage of its autoinhibitory prodomain,…
