FERONIA and ANJEA are not required in the stigma for Arabidopsis thaliana self-incompatible pollen rejection, in SI-Col-0 {psi}srka-1–based transgenic lines.
- Why it matters: SRK-dependent signaling downstream of SI pollen perception is incompletely defined in Arabidopsis, and it is unclear whether FER/ANJ act as conserved stigma components.
- What they did: The authors crossed {psi}srka-1 into SI-Col-0 to avoid SRK transgene silencing, then introduced T-DNA fer and anj-1 herk1-1 mutants and assayed pollen–stigma interactions.
- The result: SI phenotypes in SI-Col-0 fer and SI-Col-0 anj-1 lines indicate FER and ANJ are dispensable for rejection, supporting divergence of the downstream SI pathway in Arabidopsis.
