Fig. 2

Chromosome distribution of the YSL gene family in maize. The location of 19 YSL genes on the chromosome was mapped according to the maize genome. The chromosome numbers are shown at the top of each chromosome, and the scale is in megabases (Mb). Duplicated YSL gene pairs are linked by a brown line between the genes. Blue indicates the first subgroup gene, orange indicates the second subgroup gene, green indicates the third subgroup gene, and red indicates the fourth subgroup gene
