Expression level of NAC and YABBY transcription factor during seven developmental stages of soybean seedling. The graph shows a clear expression pattern for NAC and YABBY transcription factors during soybean seedling developmental stages. (a) NAC family transcription factor expression level measured by RNA-Seq during seedling development. (b) YABBY transcription factor expression level measured by RNA-Seq during seedling development. Their expression gradually increased from germinating cotyledons stage 1 to stage 4. The highest level of expression is found at stage 4. Then it gradually decreased as the germinating cotyledons are advanced to the subsequent stages. RNA-Seq data has been normalized to reads per kilobase of gene model per million mapped reads (RPKM) values and we have made two replicates of each stage.
