Fig. 1From: An insight into the gene expression evolution in Gossypium species based on the leaf transcriptomesStatistics on expressed coding genes in the seedling leaves of cotton species. A Distribution of expression levels of coding genes; B Number of expressed genes; C Relationship between the number of expressed genes and genome size. At1/At2 and Dt1/Dt2 indicate the A- and D-subgenome of the tetraploids AD1/AD2, respectivelyBack to article page
