Fig. 1From: Integrated analysis of transcriptome and miRNAome reveals the heat stress response of Pinellia ternata seedlingsPhysiological responses of Pinellia ternata seedlings before and after heat treatment. (A) P. ternata seedlings phenotypes in response to heat stress. Plants were grown in soil to the three-leaf stage and subjected to a 40 ℃ stress treatment for 24 h (left, scale bar = 4 cm). DAB and NBT staining from the same part of P. ternata seedlings before and after heat treatment (right, scale bar = 15 mm). (B) MDA and chlorophyll contents, and POD activities in P. ternata seedlings under control and heat treatment for 24 h. Except where noted, all data are presented as mean (n = 3) and standard deviation. Data were analyzed by Student’s t-test and one-way ANOVA. * and ** indicate significant differences between control and heat treatment plants at the P < 0.05 and P < 0.01 levels, respectivelyBack to article page
