【摘要】:We isolated a mutant showing perturbations in the development of male and female floral organs and fruits. Analysis of the single nucleotide polymorphisms from bulked F_2 pools identified the causative variant occurring in Csa4G126690. Csa4G126690 shows high homology to Arabidopsis SEPALLATA2(SEP2) thus being designated Cs SEP2. The causative variant was located on the splicing site of Cs SEP2, resulting in the skipping of exon 6 and abolishment of the transcriptional activity. Our data suggest that Cs SEP2 is involved in the floral organ and fruits development by conferring transcriptional activity.
