Abstract excerpt
SOMATIC EMBRYOGENESIS RECEPTOR-LIKE KINASEs (SERKs), particularly BRASSINOSTEROID INSENSITIVE1-ASSOCIATED KINASE 1 (BAK1) (SERK3) and BKK1 (SERK4), function as pleiotropic coreceptors to transduce extracellular developmental and immune signals in Arabidopsis thaliana. However, SERK5, the closest paralog of BAK1/BKK1, is long considered a nonfunctional kinase due to a mutation in the conserved arginine-aspartic...
