The two #systemin #peptide #receptors in tomatoes have opposite functions. While SYR1 activates systemin-induced #immune responses, SYR2 acts as an antagonist. Wounding preferentially induces the expression of SYR2 that attenuates immune responses by outcompeting SYR1 for binding with the co-receptor SERK3a

How minimalist plant immune molecules become activated
A groundbreaking study reveals how phase separation, akin to oil and water mixing, drives the activation of plant immune proteins, shedding light on their vital role in defending against infections. The findings uncover a fundamental mechanism for bolstering plant immunity, with implications for understanding broader immune system dynamics across species.
