A proposed model for the role of RH27 in zygote division and stem cell homeostasis. Based on the facts that mutations of RH27 caused a zygote-lethal phenotype (rh27-1) and defective stem cell homeostasis (rh27-2), and RH27 interacts with DDL, HYL1, and SE, associates with pri-miRNAs, and promotes the accumulations of miR164, miR171, and miR165/166, it is proposed that RH27 is a key player in zygote division, stem cell homeostasis and miRNA biogenesis in Arabidopsis. It should be noted that direct evidence for the involvement of miRNAs in zygote division is still lacking; therefore, a question mark is used.
