Dataset Summary
| Title | Functional analysis of Salix purpurea genes support roles for ARR17 and GATA15 as master regulators of sex determination |
| Description | The Salicaceae family is of growing interest in the study of dioecy in plants because the sex determination region (SDR) has been shown to be highly dynamic, with differing locations and heterogametic systems across taxa. Previous studies investigating the mechanisms regulating sex in the genus Salix have been limited to genome resequencing and differential expression, which are mostly descriptive in nature, and functional validation of candidate sex determination genes has not been conducted. Here we use functional analysis to test a suite of previously identified candidate genes involved in sex determination and sex dimorphism in the bioenergy shrub willow Salix purpurea. Six candidate master regulator genes for sex determination were overexpressed in Arabidopsis, followed by floral proteome analysis. Eleven transcription factors with predicted roles in mediating sex dimorphism downstream of the SDR were tested using DAP-Seq in both male and female S. purpurea DNA. The results of this study provide further evidence to support models for the roles of ARR17 and GATA15 as master regulator genes of sex determination in S. purpurea, contributing to a regulatory system that is notably different from that of the related genus Populus. Two transcription factors, an AP2/ERF family gene and a homeodomain-like transcription factor, have evidence supporting roles in downstream regulation of sex dimorphism. |
