Salad days – tomatoes that last longer and still taste good

The tomato ( Solanum lycopersicum ) is one of the most valuable fruit crops in the world with an annual global value in excess of $50Bn. We eat so many they also play an important role in our diet providing valuable vitamins, minerals and health promoting phytochemicals. Plant breeders are working continuously to supply high yielding, better tasting, more nutritious and longer lasting tomato...

Breeding wildness back into our fruit and veg

Wild tomatoes are better able to protect themselves against the destructive whitefly than our modern, commercial varieties, new research has shown. The study, published in the academic journal Agronomy for Sustainable Development, shows that in our quest for larger, redder, longer-lasting tomatoes we have inadvertently bred out key characteristics that help the plant defend itself...

Wild tomato genome sequence could help improve stress tolerance of domestic tomatoes

The genome of a inedible wild tomato ( Solanum pennellii ) has been published in Nature Genetics, and it is hoped that it may prove useful in improving certain traits, such as drought tolerance and taste, in domestic strains of tomato.   Journal Reference : Anthony Bolger et al.  The genome of the stress-tolerant wild tomato species Solanum pennellii .  Nature...

Genetic discovery points way to greater yields in tomato and other flowering food plants

Every gardener knows the look of a ripe tomato. That bright red color, that warm earthy smell, and the sweet juicy flavor are hard to resist. But commercial tomato plants have a very different look from the backyard garden variety, which can grow endlessly under the right conditions to become tall and lanky.  Tomatoes that will be canned for sauces and juice are harvested from...

Tomato Therapy: Targeting intestinal lipids to improve cholesterol

Researchers at UCLA have discovered that a specific type of lipid in the small intestine may play a greater role than previously thought in generating the high cholesterol levels and inflammation that lead to atherosclerosis. Unsaturated lysophosphatidic acids (LPAs) were previously considered very minor because they are found in far smaller amounts in the small intestine than other lipids,...

You say tomato, I say comparative transcriptomics

Researchers in the U.S., Europe and Japan have produced the first comparison of both the DNA sequences and which genes are active, or being transcribed, between the domestic tomato and its wild cousins. The results give insight into the genetic changes involved in domestication and may help with future efforts to breed new traits into tomato or other crops, according to Julin Maloof,...
