Flowering Under Stress
The Plant Cell: In a NutshellPark H.J., Gamez-Arjona F., et al. show how plants reset the time of flowering under salinity stress. Plant Cell https://doi.org/10.1093/plcell/koac289
Background: For plants, extremes in the cardinal conditions of light, temperature, nutrients and water availability are major drivers of natural selection.…
A Lightclub in the nucleus: protein liaisons optimizing plant photo-responses

A Central Role for Genetics in Plant Biology (Annu. Rev. Plant Biol.)
Plant Science Research Weekly
Plant biology as a field of study encompasses a rich plethora of subjects, some of which themselves are their own fields. Maarten Koornneef, in this memoir-style article, describes how genetics in particular shaped his career that saw the rise of Arabidopsis as the lovable poster child of plant biology…

Dissection of cell-type-specific chromatin access
Blog, The Plant Cell: In a NutshellTian et al.
Background: Flowering time plays an important role in plant reproductive success. In the model plant, Arabidopsis thaliana, several flowering time pathways adjust flowering time in response to day length), hormones, and temperature (i.e. vernalization a period of cold). During photoperiodic…
