During pollen-stigma interaction, pollen coat protein B-class peptides (PCP-Bs) compete with stigmatic rapid alkalinization factor (RALF) for interaction with FERONIA/ANJEA receptor kinases (FER/ANJ), stimulating pollen hydration and germination. However, the molecular mechanism underlying PCP-Bs-induced, FER/ANJ-regulated compatible responses remains largely unknown. Through PCP-Bγ-induced phosphoproteomic analysis, we characterized a series of pollination-related signaling pathways regulated by FER/ANJ.

Studies on MYBs have mainly focused on animals and plants; however, comprehensive analysis across other supergroups such as SAR (stramenopiles, alveolates, and rhizarians) is lacking. This study characterized the structure, evolution, and expression of MYBs in four brown algae, which comprise the biggest multicellular lineage of SAR.
