Fruit ripening is a process unique to plants that makes their fruit more appealing to seed-dispersing animals. Ripening involves a combination of physiological and metabolic reprogramming events that lead to…
Tools to unravel the mystery of why some tomatoes are hairier than others
Research, The Plant Cell, The Plant Cell: In a NutshellGaldon-Armero et al. present an image resource that can be used to identify natural variation in leaf epidermal development in tomato. The Plant Cell (2020). https://doi.org/10.1105/tpc.20.00127

Background: Just like our…
The tomato pan-genome uncovers new genes and a rare allele regulating fruit flavor (Nature Gen.)
Plant Science Research WeeklyThe wide variety of shape and flavor in modern cultivated tomatoes is a result of introgressions from its wild relatives. While many genetic studies were successful in the identification of wild alleles that affect tomato aroma, no tools were available to study structural variants affecting the taste,…

Rhizosphere microbiota structure alters to enable wilt resistance in tomato (Nature Biotech. - $)
Plant Science Research WeeklyPlants are frequently attacked by pathogens, but the pathogen-resistance is often attributed to the host. While interactions between the plant and its microbiota are recognized for their role in plant growth, their role in pathogen resistance is unknown. Kwak et al. studied the effect of soil-borne pathogen Ralstonia…
De novo domestication of wild tomato using genome editing (Nature Biotech - $)
Plant Science Research WeeklyBreeding of crops typically focuses on yield increase, and is accompanied with the loss the genetic diversity, reduced nutritional value as well as susceptibility to environmental stress. As many domestication traits exhibit simple Mendelian inheritance patterns, Zsögön et al. targeted known domestication…
Rewiring of the fruit metabolome in tomato breeding
Blog, Plant Science Research Weekly, Research, Research BlogCell. The tomato plant has been of keen interest to mankind for centuries, and its domestication led to delicious fruits much larger than their wild, bitter-tasting ancestors. Domestication of tomato had many intended outcomes (increased fruit size, less bitter taste), and several unintended consequences.…
