Genome-wide gene expression analysis and ABA insensitive phenotype of the ONSEN-integrated lines.
(a) Venn diagram of differentially expressed genes in 13–7, 19–4 and nrpd1 under ABA stress. Microarray analysis identified significant differentially expressed (expression change was 1.5-fold or 0.67-fold, FDR <0.05) genes of 13–7 and 19–4 compared with parental nrpd1 under ABA treatment (green and red). ABA-responsive genes were identified by comparing ABA treated-nrpd1 with non-treated-nrpd1 (yellow, expression change was 1.5-fold or 2/3-fold, FDR <0.05). (b) Expression heat map of significant differentially expressed genes in 13–7 and 19–4. Genes that exhibited significant differential expression in (a) were used. The heat map shows the expression levels in wild type, nrpd1, 13–7 and 19–4, with or without ABA treatment. (c) ABA-insensitive phenotypes at germination. The phenotype of abi5 and abi4 were similar to 13–7 and 19–4 respectively.
