Expression of male-unique genes from the Y1 and Y2 regions of chromosome 9. The jojoba male-specific genes do not exist in any form in the female genome

Chr Y (9) male-specific region	Total number of genes annotated	Number of genes (CDs) unique to the male genome	Number of genes (CDs) expressed in flowers	Number of genes not expressed in flowers (No reads mapped)	Number of lowly- expressed genes (< 20 reads)	Number of intermediate- expressed genes (20–80 reads)	Number of highly- expressed genes (> 80 reads)
Y1	344	32	19	13	9	4	6
Y2	494	19	13	6	4	3	6
Total	838	51	32	19	13	7	12

The expression level was calculated as the total number of reads mapped per gene (CDS) at three flowering stages (S2, S3, S4) for five biological replicates. The unit for expression profile is number of mapped reads-coverage (per CDS of the gene)
