RNAseq of dark dissected, 3 day old Arabidopsis (col0) seedlings, including cotyledons, apical hooks and hypocotyls
Seedling establishment is a critical developmental transition that contributes to survival in the local environment. While light is the primary cue driving de-etiolation, how abiotic stress shapes early development in darkness remains unclear. We show that salinity induces a photomorphogenic-like response in dark-grown Arabidopsis thaliana seedlings, disrupting apical hook formation and soil emergence. This experiment provides an organ specific transcriptome of seedlings showing this response.
