Gene editing of the E3 ligase PIRE1 fine-tunes reactive oxygen species production for enhanced bacterial disease resistance in tomato An E3 ligase helps control plant immune responses and regulates reactive oxygen species production, offering a strategy to boost disease resistance in leav

Excited this MS is out! Here, we genome edited Pire in tomato, a conserved E3 ligase controlling NADPH oxidase accumulation in Arabidopsis. Edited lines exhibited enhanced resistance to foliar bacterial pathogens, but not two root colonizing pathogens. #PlantImmunity

Integrating ‘cry for help’ strategies for sustainable agriculture Plants recruit specific soil microbes through a sophisticated ‘cry for help’ strategy to mitigate environmental stresses. Recent advances highlight the potential of leveraging this mechanism to develop microbe-based approaches for enhancing crop health, but challenges remain in refining the criteria and conceptual frameworks to effectively investigate and harness these plant–microbe interactions.

Let the BOOSTER boost photosynthesis and plant productivity Recently, Feyissa et al. discovered an orphan gene, BOOSTER (BSTR), in Populus species, which has been shown to optimize photosynthesis and enhance CO2 assimilation and biomass accumulation. Integrating BSTR into breeding programs holds promise for boosting crop yields and contributing to food security, increased biofuel production, and sustainable agriculture.

Diagram of a cell (and mitochondrion) cross-section describing how, during salt stress, increased Na+ and abscisic acid activate the transcription factor ABI5 to promote the expression of TaGPAT6, encoding a glycerol-3-phosphate acyltransferase involved in the synthesis of cutin and suberin polyesters, which functions as an apoplastic barrier to restrict the influx of Na+ into cells.

Plants tolerate high🧂salinity by depositing cutin and suberin to form apoplastic barriers that limit the influx of ions. The question is, HOW?
