摘要
In plants,the stigma represents the initial site of pollenpistil communication and serves as a crucial location for rejection of incompatible pollen.In self-compatible(SC)plants,such as Arabidopsis thaliana from the Brassicaceae family,pollen coat protein B(PCP-B)peptides were reported to compete with stigmatic RAPID ALKALINIZATION FACTOR 33(RALF33)peptides for binding to the FERONIA/ANJEA(FER/ANJ)receptors in the stigma to promote pollen hydration via inhibition of reactive oxygen species(ROS)production(Liu et al.2021).
