The queen’s crown: Team-building the stigma at the top of the pistil

Ballester et al. reveal how stigma development in Arabidopsis requires the formation of different higher-order transcription factor complexes of increasing complexity. https://doi.org/10.1093/plcell/koab236  By Cristina Ferrándiz Instituto de Biología Molecular y Celular de Plantas, CSIC-UPV Background:…

Winter is coming: It’s time to “CRY”

Li et al. reveal how the cryptochrome CRY2 regulates freezing tolerance in Arabidopsis. https://doi.org/10.1093/plcell/koab215  By Youping Li Background: Cold acclimation via exposure to non-lethal low temperatures enhances frost resistance in plants. This process requires light; however, we know…

NF-YCs mediate plant growth during the dark-to-light transition

Zhang et al. uncover the roles of NF-YC transcription factors in repressing brassinosteroid biosynthesis and signaling to mediate photomorphogenesis in Arabidopsis. Background: Seedlings, which germinate in the soil, generally undergo rapid hypocotyl elongation to seek light for growth and development.…
