An opportunistic plant pathogen disrupts leaf microbiome through secretion of plant cell wall degrading enzymes
Plant Science Research WeeklyHealthy plants possess a functional immune system, and their leaves harbor a structured microbial community, including opportunistic pathogens. These opportunistic pathogens can trigger plant diseases under conducive conditions, such as when plant immunity is compromised, and the microbial community…
From friend to threat: the mutualist-pathogen transition of plant-fungal interaction is determined by a small gene cluster
Plant Science Research WeeklyThe 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…
Identification of a cell signaling cascade that regulate s broad-spectrum resistance (Cell Reports)
Plant Science Research WeeklyMany 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…
Removing one wheat protein kinase provides resistance to rust fungi (Cell)
Plant Science Research WeeklyTolerance 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 love potion made by soil-borne fungi (Plant Cell Environ.)
Plant Science Research WeeklyThe 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…

An interactome of plant autophagy proteins and pathogen effectors (Cell Host Microbe) ($)
Plant Science Research WeeklyAutophagy 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…
Extracellular proteolytic cascade in tomato activates immune protease Rcr3 (PNAS)
Plant Science Research WeeklyThe 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,…
