Fig. 7From: Genome-wide identification, evolutionary estimation and functional characterization of two cotton CKI gene typesExpression profiles of two types G. hirsutum CKI genes in anthers at different development stages under NT and HT conditions. a-b Expression patterns of G. hirsutum CKI genes in 84,021 and H05 at different anther developmental stages under NT and HT conditions from RNAseq (a) and Quantitative RT-PCR experiment (b). 8 N and 8H refer to 84,021 (the HT-tolerant line) under NT and HT conditions, respectively; HN and HH refer to H05 (the HT-sensitive line) under NT and HT conditions, respectively; TS: tetrads stage; TDS: tapetal degradation stage; ADS, anther dehiscence stage; FPKM: fragments per kb of transcript per million fragments mapped. The RNAseq data of the expression profiles was cited from Min et al. [33]. Error bars indicate ± standard deviations of triplicate experiments. Asterisks indicate statistically significant differences (*P < 0.05, **P < 0.01) by Student’s t-test. The GhUB7 (Gh_A11G096) was used as the reference gene to normalize the total amount of cDNA in each reactionBack to article page
