Zhang and Jian et al. reveal an epigenetic regulatory mechanism underlying gibberellin signaling-mediated flowering. https://doi.org/10.1093/plcell/koad166 By Chunyu Zhang and Xingliang Hou; South China Botanical Garden, Chinese Academy of Sciences, Guangzhou, China  Background: The timing…

Light and temperature are important external signals required by plants for flower initiation. These external signals along with some internal cues (plant age, gibberellins, etc.) are established factors for floral initiation, but the factors required for end-of-flowering time are not yet established.…

Flowering time is determined by both endogenous factors and environmental cues to ensure successful reproduction. ETHYLENE INSENSITIVE 3 (EIN3) and EIN3 LIKE 1 (EIL1) are transcription factors which are the key downstream regulators of ethylene signal transduction. Rapid flowering is promoted by the…

Park 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.…

Author(s) and Institutions: Leelyn Chong and Yingfang Zhu State Key Laboratory of Crop Stress Adaptation and Improvement, School of Life Sciences, Henan University, Kaifeng 475001, China Sanya Institute, Henan University, Sanya, 572025, China Leelyn Chong and colleagues provide cues as to how plants…

Gene expression is primarily controlled by transcriptional regulatory proteins able to recognize and bind short DNA sequences in downstream targets. Understanding how DNA-binding proteins achieve high precision and switch on/off the transcription of selected genes at a specific developmental stage or…

Choi et al. uncover the association between telomere length and flowering time variation in Arabidopsis, rice, and maize. The Plant Cell (2021) https://doi.org/10.1093/plcell/koab022   Background: Telomeres are DNA-protein complexes found at the ends of eukaryotic chromosomes that protect the…

The onset of reproductive development is tightly regulated in response to environmental cues as early and delayed flowering greatly affects seed production. In Arabidopsis, the timing of flower formation is controlled by members of the Phosphatidyl Ethanolamine-Binding Protein (PEBP) family: TERMINAL…
