Researchers from the University of California’s Davis and Berkeley campuses have identified a potential solution: activating two genes in rice egg cells that trigger their development into embryos without the need for fertilization, which would efficiently create high-yielding clonal strains of rice and other crops.</p> November 20, 2024 - 10:53am Andy Fell /news/making-high-yielding-rice-affordable-and-sustainable How Plants Become Bushy, or Not /news/how-plants-become-bushy-or-not <p>For many plants, more branches means more fruit. But what causes a plant to grow branches? New research from the University of California, Davis shows how plants break down the hormone strigolactone, which suppresses branching, to become more “bushy.” Understanding how strigolactone is regulated could have big implications for many crop plants.</p><p>The study was published August 1 in <a href="https://www.nature.com/articles/s41467-024-50928-3">Nature Communications</a><em>.</em></p> August 06, 2024 - 3:50pm Andy Fell /news/how-plants-become-bushy-or-not Plant Biologist Siobhan Brady Named HHMI Investigator /news/plant-biologist-siobhan-brady-named-hhmi-investigator <p>Siobhan Brady, a professor in the <a href="https://www-plb.ucdavis.edu/">Department of Plant Biology</a> and <a href="https://genomecenter.ucdavis.edu/">Genome Center</a> at the University of California, Davis, has been selected as a <a href="https://www.hhmi.org/programs/investigators">Howard Hughes Medical Institute (HHMI) Investigator</a>.

They also need to communicate with other plants and organisms, which they achieve by releasing volatile organic compounds (VOCs), tiny molecules that are often associated with distinct smells. Scientists know a lot about how plants emit these odorous signals, however very little is known about how they receive and interpret them.</p> April 25, 2024 - 4:10pm Andy Fell /blog/how-plants-sense-scents Researchers Identify Microbes That Help Plants Thwart Parasite /news/researchers-identify-microbes-help-plants-thwart-parasite <p><span><span><span><span><span>Bacteria that could help one of Africa’s staple crops resist a major pest have been identified by researchers at the University of California, Davis.

To cope with drought, plant roots produce a water-repellent polymer called suberin that blocks water from flowing up towards the leaves, where it would quickly evaporate. Without suberin, the resulting water loss would be like leaving the tap running.</span></span></span></span></p> January 02, 2024 - 11:32am Andy Fell /blog/how-tomato-plants-use-their-roots-ration-water-during-drought A Mixed Origin Made Maize Successful /news/mixed-origin-made-maize-successful <p><span><span><span>Maize is one of the world’s most widely grown crops. It is used for both human and animal foods and holds great cultural significance, especially for Indigenous peoples in the Americas. Yet despite its importance, the origins of the grain have been hotly debated for more than a century. Now new research, published Dec. 1 in Science, shows that all modern maize descends from a hybrid created just over 5,000 years ago in central Mexico, thousands of years after the plant was first domesticated. </span></span></span></p> November 30, 2023 - 11:00am Andy Fell /news/mixed-origin-made-maize-successful How Sunflowers See the Sun /curiosity/news/how-sunflowers-see-sun <p>Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers “see” the sun to follow it? New work from plant biologists at the University of California, Davis, published Oct. 31 in&nbsp;PLOS Biology, shows that they use a different, novel mechanism from that previously thought.&nbsp;</p> <p>“This was a total surprise for us,” said Stacey Harmer, professor of plant biology at şŮşŮĘÓƵ and senior author on the paper.&nbsp;</p> October 31, 2023 - 11:00am Andy Fell /curiosity/news/how-sunflowers-see-sun
