Carbohydrate metabolisms in Yu17S seedlings subject to chilling stress. A Heat maps illustrate transcript levels of representative cold responsive genes. The total soluble sugar (B), trehalose (C), raffinose (D) and galactinol (E) contents in the seedling of MH63 and Yu17S under cold stress (2–48 h) and recovery for 24 h after 48 h treatment. F-K Transcript levels of LOC_Os08g36910, LOC_Os10g41550, LOC_Os11g07440, LOC_Os01g07530, OsTPP1 and WSI76 in the seedling of Yu17S under cold stress (2–48 h) and recovery for 24 h after 48 h treatment. Error bars indicate the SD for three independent replicates. * and ** indicate a significant difference between MH63 and Yu17S at P < 0.05 and P < 0.01 levels, respectively (two tailed T-test). Different letters indicate significant differences among treatments (P < 0.05, ANOVA). FW, fresh weight; AMY, a-Amylase; BMY, b-amylase; GWD, glucan water dikinase; DEP1, disproportionating enzyme; SUS, Suc synthase; SPS, Suc-P synthase; HK, hexokinase; CWI, apoplastic invertase; A/N-Invs, alkaline/neutral invertase; TRE, trehalase; TPP, trehalose-6-phosphate phosphatase; TPS, trehalose-6-phosphate synthase; RS, raffinose synthase; GS, galactinol synthase
