Description
A plant's own alarm system can amplify the warning raised by a fungal invader's proteins, Imtiaz Ahmad Sajid and colleagues show in a 2026 study. The fungus Sclerotinia sclerotiorum secretes NLP proteins that trigger pattern-based immunity in Arabidopsis. The team asked whether the phytocytokine receptors PEPR1 and PEPR2 help carry that signal.
Treatment with the fungal protein SsNLP1 switched PEPR genes on strongly. Plants missing both receptors responded weakly, with less oxidant burst, fewer defense genes, and poorer resistance to the fungus. Plants overproducing PEPR1 answered more strongly on every count. The results show plant cytokine signaling reinforcing pathogen-pattern immunity against a broad-host-range rot.
