To investigate the role of LLM-domain B-GATAs in starch metabolism we performed gene expression profiling analysis of RNA-seq data, obtained with Illumina technologies. B-GATA double mutant gnc gnl and the transgenic line overexpressing GNL were grown in dark conditions to avoid interference from photosynthesis or other light-dependent processes affecting sugar and starch biosynthesis. Overall design: Transcriptome comparison including three replicate measurements of three biological samples.
