Fig. 7From: Genome-wide identification and characterization of ABA receptor PYL/RCAR gene family reveals evolution and roles in drought stress in Nicotiana tabacumThe expression profile of 29 NtPYLs in response to drought treatment. The relative transcript abundances of 29 NtPYLs were examined via microarray and visualized as a heatmap. The 6–7 weeks old Nicotiana tabacum seedings grown in the soil were treated by air dehydration. The X axis is represented for the indicated time after drought treatment. The color scale represents Log2 expression valuesBack to article page
