Complex but different... Jarosz-Ostrówka et al. show that the Elongator complex protein ELO3-6 is required for seedling #photomorphogenesis, mainly playing a transcriptional & translational role during hypocotyl growth & cotyledon development, respectively doi.org/10.1093/pcp/... #PlantScience
Proposed model of Elongator functions in Arabidopsis photomorphogenesis. Taken from Magdalena Jarosz-Ostrówka, Małgorzata Kwaśniak-Owczarek, Natalia Małecka, Magda Mielczarek, Paweł Migdał, Olimpia Gagliardi, Mieke Van Lijsebettens, Paweł Mackiewicz, Magdalena Wołoszyńska, Elongator complex differentially regulates transcription and translation in the hypocotyl and cotyledons during early light-dependent Arabidopsis development, Plant and Cell Physiology, Volume 67, Issue 5, May 2026, Pages 826–846, https://doi.org/10.1093/pcp/pcag005

Brassinosteroid signalling suppresses chlorophyll biosynthesis via BGH2-GLK modules to ensure proper cotyledon greening during de-etiolation
Abstract. Brassinosteroids (BRs) are phytohormones that play essential roles in skotomorphogenesis under dark conditions, coordinating not only development

Happy to share our paper is now online in PCP. 🌱 @plantcellphysiol.bsky.social We found that BR signalling suppresses Chl biosynthesis in the dark via the BGH2–GLK module, allowing seedlings to green properly when exposed to light. @camplantsci.bsky.social doi.org/10.1093/pcp/...
