Biotic and abiotic stress responses
WebMar 30, 2012 · ABA is now considered a global regulator of stress responses that can dominantly suppress pathogen defence pathways, thus controlling the switch in priority between the response to biotic or abiotic stress and allowing plants to respond to the most severe threat (Asselbergh et al., 2008b). ABA production may therefore be the … WebNov 6, 2024 · Biotic and Abiotic Stress Responses in Crop Plants 1. Introduction.

WebThe abiotic stress ultraviolet-B (UV-B) light induces the production of UV-protective flavonols in Arabidopsis Col-0 cell suspension cultures and this accumulation is attenuated by concurrent application of the bacterial elicitor flg22 (simulating biotic stress). This inhibition correlates with strong suppression of the flavonol biosynthesis genes.
