Their research revealed that the\u00a0<em>Rider<\/em>\u00a0family is also present and active in other plants such as\u00a0rapeseed, beetroot, and quinoa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Transposons, or jumping genes, are mobile snippets of\u00a0DNA code\u00a0that copy themselves into new positions within the\u00a0genome. Discovered by Nobel prize-winning scientist Barbara McClintock in the 1940s, only now are scientists realizing that transposons are not junk at all but actually play an important role in the evolutionary process, and in altering gene expression and the physical characteristics of plants.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This discovery brings a new potential source of new trait variations that could help plants better cope with more extreme conditions brought by\u00a0changing climate. By identifying that\u00a0<em>Rider<\/em>\u00a0activity is triggered by\u00a0drought\u00a0suggests that it can create new gene regulatory networks that would help a plant respond to drought. This also means that\u00a0<em>Rider<\/em>\u00a0could help develop crops that are better adapted to drought stress by providing them with drought responsiveness\u00a0genes\u00a0from other crops.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For more details, read the news article in the\u00a0<a rel=\"noreferrer noopener\" href=\"https:\/\/www.cam.ac.uk\/research\/news\/harnessing-tomato-jumping-genes-could-help-speed-breed-drought-resistant-crops\" target=\"_blank\"><strong>University of Cambridge website<\/strong><\/a><strong>.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Source: <a href=\"http:\/\/www.isaaa.org\/kc\/cropbiotechupdate\/article\/default.asp?ID=17747\"><strong>ISAAA<\/strong><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers from the University of Cambridge&#8217;s Sainsbury Laboratory (SLCU) and Department of Plant Sciences have discovered that drought stress can trigger the activity of a family of jumping genes (Rider\u00a0retrotransposons) previously known to contribute to fruit shape and color in tomatoes.
