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 Modern Plants Show More Insect Damage Than Fossilized Plants /blog/modern-plants-show-more-insect-damage-fossilized-plants <p>Despite widespread insect declines, plants are experiencing “unprecedented levels of insect damage” in comparison to their fossilized counterparts, according to new research by a trio of scientists including ٺƵ entomologist&nbsp;<a href="https://entomology.ucdavis.edu/people/emily-meineke">Emily Meineke</a>.&nbsp;</p> October 14, 2022 - 4:26pm Andy Fell /blog/modern-plants-show-more-insect-damage-fossilized-plants Study Challenges Evolutionary Theory That DNA Mutations Are Random /food/news/study-challenges-evolutionary-theory-dna-mutations-are-random ٺƵ researchers have found that DNA mutations are not random. This changes our understanding of evolution and could one day help researchers breed better crops or even help humans fight cancer.

Root-associated microbes help plants take up nutrients from the soil, so the finding could help in understanding how rice responds to dry spells and how it can be made more resilient to drought.
