Genome contents:
The SDR region is subtelomeric and has a much lower gene density than the genome-wide average with mere 150 genes across the 5-Mb region. The SDR region is enriched for genes involved in reproduction and it contains several candidate sex-determination genes.
Achn342721, a homologue to FBL17 in Arabidopsis, essential for male fertility and germ line proliferation29 and Achn226501, a homologue of Caleosin, involved in lipid storage in maturing seeds.
