mRNA expression patterns of different genes in latex during the 1st tapping of trees treated with exogenous phytohormones. a: Gene expression levels in latex of the trees treated with ethephon; b: Gene expression levels in latex of the trees treated with methyl jasmonate. Different lowercase and uppercase letters on top of the bars among different treatment times for each gene indicate significance at the 0.05 and 0.01 levels, respectively. Different capital and lowercase letters in cell grids denote significant differences among different genes within the same treatment time at the 1 and 5% levels, respectively
