  • Nature's mirror—the code for chirality

  • On Darwin's birthday, tomato genetics study sheds light on plant evolution
    more resilient crop plants in a time of changing climate by boosting resistance to pests or severe weather using crossbreeding methods rather than genetic engineering Tomatoes were used for the study because they are an ecologically and reproductively diverse plant group said Moyle who was part of a team of researchers that visited Ecuador in May 2014 to collect different populations of tomatoes native to the Andes Mountains a biodiversity hotspot Although better known for his work on finches Darwin also hunted on the Galapagos Islands of Ecuador for wild tomatoes one of the hundreds of plant and animal species collected by the British naturalist during his landmark trip to the archipelago in 1835 Nearly 200 years later these plants are still revealing important new insights into evolution Moyle said By bringing modern technology to bear on these tomatoes the study was able to clarify genetic relationships and assess the flow of genes between these wild plant species as well as reveal the genetic root of specific environmental adaptations Although wild tomato species living in the driest deserts on Earth or high up in the Andes Mountains are very different in many of their traits from the domesticated tomatoes we eat by the millions they are surprisingly similar at the genomic level Pease said The team found evidence to support three major genetic strategies behind the tomato s ability to rapidly adapt to ecological change the recruitment of genes from a common ancestral pool the trading of genes between species through a form of natural crossbreeding called introgression and the rapid accumulation of new genetic mutations This latter category was highlighted by the surprising number of new mutations in genes found in the tomatoes Of the four main groups of wild tomatoes in the study scientists discovered hundreds to thousands
