Transcript expression patterns of selected plasticity-responsive candidate genes for root growth and drought tolerance. a Expression within different tissues of wheat represented as root apical meristem_5 (tillering stage), roots_10 (flag leaf stage), roots_15 (30% spike), roots_20 (14-days old), roots_25 (seven leaf stage), roots_30, roots_35 and roots_40 (fifth leaf stage), flag leaf_1 (milk grain stage), flag leaf_8 (12 dpa), grain_10 (ripening stage), leaf_105 (9-days old), second leaf_15 (17-days old), shoot apical meristem_5 (tillering stage), shoots_25 (2-days old) and spike_20 (flag leaf stage). Deep blue color indicates lower and deep coral color indicates higher expression values (log2 TPM). b Expression patterns of candidate genes under 1 h (deep sky blue color bar) and 6 h (black color bar) of drought treatments. RNA-seq data were curated from the Wheat Gmap database and are represented by a heatmap of transcripts per kilobase million (TPM) values. The expression data is also provided in Supplementary Table S2 and S3
