横坐标大写字母分别代表对照组(CK)、干旱组(D)、热激组(H)及干旱-热激复合组(DH)ꎮ 大写字母后的数字代表两种不同的
生长条件:液体培养基(1)、土壤基质(2)ꎮ 纵坐标数字代表相对表达量ꎮ A. 液体培养基条件下不同组织(根状茎与肉质叶) 中
PwDREB2A/ 2AL1 / 2AL2 / 2D 基因的表达模式ꎬ将 CK1 组根状茎或肉质叶的样品表达量设定为 1ꎻ B. 两种不同生长条件下肉质叶
样品中 PwDREB2A/ 2AL1 / 2AL2 / 2D 基因的表达模式ꎬ将 CK1 / 2 组肉质叶的样品表达量设定为 1ꎮ 不同字母 A-D 代表具有显著性

The capital letters of X ̄axis represented mock group (CK)ꎬ drought group (D)ꎬ heat shock group (H) and drought ̄heat shock combined group
(DH)ꎬ respectively. The numbers after capital letters represent two different growth conditions: liquid medium (1)ꎬ soil matrix (2). The
numbers of Y ̄axis represent the relative expression. A. Expression patterns of PwDREB2A/ 2AL1/ 2AL2/ 2D genes in different tissues (rhizome
and fleshy leaf) with liquid mediumꎬ and the expression level of rhizome or fleshy leaf in CK1 group is set to 1ꎻ B. Expression patterns of
PwDREB2A/ 2AL1/ 2AL2/ 2D genes in fleshy leaves with two different growth conditionsꎬ and the expression level of fleshy leaf in CK1/ 2 group
is set to 1. Different letters of A-D represent significant differences at the P<0.01 level determined by Duncan’s new multiple range tests.
