Aflatoxin-free transgenic maize using host-induced gene silencing
Plant Science Research Weekly, Research0 Comments
/
Aflatoxins are toxic metabolites produced by some species of Aspergillus fungi that can occur on numerous crop plants. When ingested by animals, aflatoxins cause health problems including liver cancer and stunted growth. Thakare et al. used host-induced gene silencing (HIGS) to block aflatoxin production…
Divergent evolution driven by pollinators
Plant Science Research Weekly, ResearchA great variety of plants rely on pollinators to be fertilized successfully. This close relationship is thought to drive evolutionary diversification in plants, making the presence or absence of pollinators in response to climate change an increasingly relevant matter. Gervasi and Schiestl addressed…
Root microbiota drive direct integration of phosphate stress and immunity
Plant Science Research Weekly, ResearchMany of the genes involved in the phosphate-stress response (PSR) have been identified from plants growing on sterile medium. Castrillo et al. examined how the root microbiota affectthe phosphate stress response, and how phosphate affects the association between roots and microbes. Plants deficient…
Reviews: Nature Insight: Plants ($)
Plant Science Research Weekly, ResearchNature journal published a special “Plant Insights” section featuring several excellent reviews. Zipfel and Oldroyd review Plant signalling in symbiosis and immunity (10.1038/nature22009), Bevan et al. write about Genomic innovation for crop improvement (10.1038/nature22011), Scheres and van der…
Review: Quantitative resistance: More than just perception of a pathogen
Plant Science Research Weekly, ResearchSome forms of pathogen resistance function like an on/off switch: if a plant has an appropriate receptor it recognizes a pathogen and shows resistance. Corwin and Kliebenstein review the other kind of resistance, quantitative resistance, in which many genes make small contributions to the plant’s resistance.…
Review: Receptor kinases in plant pathogen interactions: More than pattern recognition
Plant Science Research Weekly, ResearchZhou et al. review the contributions of Receptor-Like Kinases (RLKs) and Receptor-Like Proteins (RLPs) as Pattern Recognition Receptors (PRRs) that contribute to the recognition of pathogens, as well as the contributions of receptor-like cytoplasmic kinases (RLCKs). The authors summarize recent studies…
Plant immune and growth receptors share common signaling components but localize to distinct plasma membrane nanodomains
Plant Science Research Weekly, ResearchSignal transduction in plant and animal cells is often initiated at the plasma membrane (PM) and involves common signaling components, raising the question of how receptor complexes elicit distinct signaling outputs. To address this question, Bücherl et al. investigated physical characteristics of the…
A Salivary Effector Aids in Brown Planthopper Feeding on Rice Plants
Plant Physiology, Plant Physiology: On The Inside, ResearchHerbivory-induced plant cell wall modifications play an important role in deterring herbivory. Modified cell walls not only act as physical defenses against herbivores by enhancing the mechanical hardness of plant tissues but also reduce the digestibility of food for herbivores, thereby functioning as…
Stomatal immunity: Roles of MAP kinases and cytokinin
Plant Science Research Weekly, ResearchWhen a pathogen is perceived, plants have the ability to induce stomatal closure to prohibit the pathogens from passing into the inner tissues; this response is known as stomatal immunity. Two new papers in The Plant Cell investigate mechanisms by which pathogen perception is transduced into stomatal…
