AI Article Synopsis
- - The study investigates the genes linked to sex determination in seabuckthorn, a dioecious plant, by identifying homologous genes involved in floral development.
- - Researchers shortlisted 44 putative genes from model plants and found 29 homologous sequences in seabuckthorn, with 21 showing differential expression in male or female flower buds.
- - Notably, HrCRY2 was strongly expressed in female buds, while HrCO was specific to male flowers, indicating that understanding these genes could reveal the sex determination mechanism in seabuckthorn.
Article Abstract
Seabuckthorn is an economically important dioecious plant in which mechanism of sex determination is unknown. The study was conducted to identify seabuckthorn homologous genes involved in floral development which may have role in sex determination. Forty four putative Genes involved in sex determination (GISD) reported in model plants were shortlisted from literature survey, and twenty nine seabuckthorn homologous sequences were identified from available seabuckthorn genomic resources. Of these, 21 genes were found to differentially express in either male or female flower bud stages. HrCRY2 was significantly expressed in female flower buds only while HrCO had significant expression in male flowers only. Among the three male and female floral development stages (FDS), male stage II had significant expression of most of the GISD. Information on these sex-specific expressed genes will help in elucidating sex determination mechanism in seabuckthorn.
