Double trouble: The Solanum pan-genome shows gene duplication complicates predictability
Plant Science Research WeeklyA pan-genome has been assembled for the Solanum genus, which contains many diverse and economically important crops including potato, tomato, and African eggplant. Genomes were assembled for 22 species, and genes were predicted based on previous reference genomes and from RNA sequences across multiple…

A Mediator–transcription factor module that regulates fruit ripening in tomato
The Plant Cell: In a NutshellDeng, 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
The Plant Cell: In a NutshellHuang 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…

Background: In flowering plants, flower morphology influences pollination.…
Marginal differences play a central role in complex leaf development
Blog, Research, The Plant Cell, The Plant Cell: In BriefDevelopment 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…

Tempting Fate: A Guanylate-Binding Protein Maintains Tomato Fruit Cell Differentiation
Blog, Research, The Plant Cell, The Plant Cell: In BriefTissues 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…
