Blue light, PAS/LOV photoreceptor and GDP-L-galactose phosphorylase (GGP): the Triumvirate controlling ascorbic acid biosynthesis in plants

Bournonville et al. explore which factors control ascorbic acid biosynthesis in plants and its accumulation in fruits. https://doi.org/10.1093/plcell/koad108 Céline Bournonville, Bayer SAS, 1050 Route de Pardies, 40300 Peyrehorade, France Kentaro Mori, Université Bordeaux, INRAE, UMR Biologie…

A Mediator–transcription factor module that regulates fruit ripening in tomato

Deng, Yang, Li, Chang, Sun et al. explore the interaction between EIN3-like transcription factors and subunits of the Mediator complex in tomato fruit ripening. Background: Fruit ripening relies on the precise spatiotemporal control of RNA polymerase II (Pol II)-dependent transcription of thousands…

A molecular framework for ethylene-mediated tomato fruit development

Huang et al. unravel the roles of ethylene in tomato fruit growth and ripening.  Background: Fruit development is an intriguing evolutionary strategy that functions in both seed protection and seed dispersal. Tomato (Solanum lycopersicum) has long been used as a model system to uncover mechanisms…

Stigma retracted into anther tube needs two steps

Shang and colleagues investigated the molecular mechanisms that contributed to stigma insertion during tomato domestication and improvement.  By Lele Shang, Jianwen Song and Yuyang Zhang, Huazhong Agricultural University  Background: In flowering plants, flower morphology influences pollination.…

Marginal differences play a central role in complex leaf development

Development involves a delicate patterning of cell division and differentiation in three dimensions. This is beautifully illustrated in leaves, where three axes are visible: proximo-distal (from base to tip), medio-lateral (from the midvein to the margin/edge of the blade) and adaxial-abaxial (from upper…

MED25 Mediates Shade-Induced Hypocotyl Elongation in Tomato

Tempting Fate: A Guanylate-Binding Protein Maintains Tomato Fruit Cell Differentiation

Tissues are composed of specialized cell types. As a cell matures, it acquires the characteristics associated with a specific identity, or fate. This process is called cell differentiation and is crucial for proper organ development. However, after a differentiation program is initiated, the mechanisms…
