TL;DR: A comparison of open chromatin landscapes reveals commonalities in transcriptional regulation across species and identifies a transcription factor cascade in the Arabidopsis root hair, which appears to control both cell fate regulators and abiotic stress responses.

TL;DR: It is shown that the circadian clock of cultivated tomato (Solanum lycopersicum) has slowed during domestication, and the EID1 allele in cultivated tomatoes enhances plant performance specifically under long day photoperiods, suggesting that humans selected slower circadian rhythms to adapt the cultivated species to the long summer days it encountered as it was moved away from the equator.

TL;DR: To understand variation in gene regulatory networks activated by submergence, a high-resolution analysis of chromatin accessibility and gene expression at three scales of transcript control in four angiosperms, ranging from a dryland-adapted wild species to a wetland crop, defined a cohort of conserved submergence-activated genes with signatures of overlapping cis regulation by four transcription factor families.

TL;DR: A MYB-driven regulatory module unique to the hair cell is identified, which appears to control both cell fate regulators and abiotic stress responses and shed light on the mechanisms producing cell type-specific transcriptomes during development.

TL;DR: In this paper, the tomato root cell type translatomes were profiled and examples of functional innovation, repurposing, and conservation of transcription factors were described, relative to the model plant Arabidopsis.
