SERK5 genetically compensates for the loss of BAK1 and BKK1 in regulating elf18-triggered immune signaling in Arabidopsis

Proceedings of the National Academy of Sciences, Volume 122, Issue 46, November 2025. <br/>SignificanceTheArabidopsis SERKfamily encodes key coreceptors that transduce extracellular developmental and immune signals. Previous studies show that concurrent loss of BAK1 (SERK3) and BKK1 (SERK4), two essential coreceptors in PTI, activates ETI. …
