Fig. 4From: Aldehyde dehydrogenase superfamily in sorghum: genome-wide identification, evolution, and transcript profiling during development stages and stress conditionsExpansion of ALDH gene family in different species. Changes in the copy number of the ALDH genes in A sorghum and maize, as well as B sorghum and rice, were analyzed. The values in circles and rounded squares show the number of ALDH genes in ancestral and extant species, respectively. Numbers with plus and minus symbols on branches refer to the number of gene expansions and losses, respectivelyBack to article page
