The tomato pan-genome uncovers new genes and a rare allele regulating fruit flavor (Nature Gen.)

The 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,…

MYB21 in Tomato: No Seeds Without Me

https://doi.org/10.1105/tpc.18.00978  Schubert et al. identified a transcription factor that regulates ovule development in tomato. By Ramona Schubert and Bettina Hause Leibniz Institute of Plant Biochemistry, D06120 Halle/Salle, Germany Background: The survival of most plant species depends…

Rhizosphere microbiota structure alters to enable wilt resistance in tomato (Nature Biotech. - $)

Plants 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…

Domestication of wild tomato is accelerated by genome editing (Nature Biotech. - $)

Wild tomato, Solanum pimpinellifolium, exhibits remarkable tolerance to salt stress and bacterial spot disease. Domestication of S.pimpinellifolium requires adjustment of day-length sensitivity, plant compactness, fruit size and the fruit could benefit from increased vitamin C content. Li et al. used…

De novo domestication of wild tomato using genome editing (Nature Biotech - $)

Breeding 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…
