Figure 3 - Physical position of the ore gene on Cucumis sativus chromosome 3. Blue diamonds below the seven chromosomes indicate the positions of 43 SNPs c Mutation at residue 257 changing the conserved amino acid of a putative β-carotene hydroxylase (CsaBCH1). Xishuangbanna group cucumbers carry asparagine, whereas all other cucumbers and homologous proteins from ten other species carry alanine d CsaBCH1 mRNA levels in Xishuangbanna cucumbers that accumulate β-carotene.
