OAF is a DAF-like gene that controls ovule development in plants

We previously found that the RING-type E3 ligase DEFECTIVE IN ANTHER DEHISCENCE1- (DAD1-) Activating Factor (DAF) controls anther dehiscence by activating the jasmonate biosynthetic pathway in Arabidopsis. Here, we show that in Arabidopsis, the DAF ancestor was duplicated into three genes (DAF, Ovul...

description We previously found that the RING-type E3 ligase DEFECTIVE IN ANTHER DEHISCENCE1- (DAD1-) Activating Factor (DAF) controls anther dehiscence by activating the jasmonate biosynthetic pathway in Arabidopsis. Here, we show that in Arabidopsis, the DAF ancestor was duplicated into three genes (DAF, Ovule Activating Factor (OAF), DAFL2), which evolved divergent partial functions from their ancestor through subfunctionalization. In this case, DAF-DAD1-JA signaling regulates anther dehiscence, whereas OAF controls ovule development by negatively regulating cinnamyl alcohol dehydrogenase 9 (CAD9) activity and being negatively regulated by miR847 itself in Arabidopsis. Downregulation of OAF or upregulation of CAD9 and miR847 caused similar abortion of ovule formation due to precocious ovule lignification in transgenic Arabidopsis. Interestingly, only one DAF-like gene, PaOAF, exists in the monocot orchids, which has likely evolved through nonfunctionalization and maintains a conserved function as Arabidopsis OAF in regulating ovule development since defective ovules were observed in the virus-induced gene silencing (VIGS) PaOAF Phalaenopsis orchids. The absence of the DAF ortholog and its function in orchids is likely due to the evolution of stamens to a unique pollinium structure that lacks the feature of anther dehiscence. These findings expand the current knowledge underlying the multifunctional evolution and diverse functionalization of duplicate gene pairs within/among plants.
