The development of maternal egg cells is pivotal for survival – but also precarious. During meiosis, the DNA-containing chromosomes can easily be broken or lost, causing infertility, miscarriage, or genetic disorders. Scientists have struggled to study these crucial cellular events in humans and other mammals.
Rice is a staple food crop for more than half the world’s population, but most farmers don’t grow high-yielding varieties because the seeds are too expensive. 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.
Wolf Dietrich-Heyer, a Distinguished Professor and chair in the Department of Microbiology and Molecular Genetics was among three members of the UC Davis community recognized for their remarkable efforts to steward donors and raise the culture of philanthropy across the university.
The Office of Development and Alumni Relations and the UC Davis Foundation presented the 2024 Faculty and Staff Stewardship Awards during a ceremony on Oct. 19. The recipients are:
Sam Arcement—Director of Graduate Academic Programs for the College of Biological Sciences, and the program coordinator for the Molecular, Cellular, and Integrative Physiology (MCIP) Graduate Group—has been honored with the 2024 Outstanding Graduate Program Coordinator Award from the Office of Graduate Studies. This year saw a record number of nominations. “Sam tirelessly ensures that our needs and concerns are heard and addressed,” said one MCIP student, who praised Arcement’s dedication to student advocacy.
You have likely not spent much time thinking about the uterus of the fruit fly, Drosophila melanogaster. But then, neither have most scientists, even though Drosophila is one of the most thoroughly studied lab animals. Now a team of biologists at the University of California, Davis, has taken the first deep look at the Drosophila uterus and found some surprises, which could have implications not just for understanding insect reproduction and potentially, pest control, but also for understanding fertility in humans.
Commitment.Passion. Empathy. These descriptors were just a few of the plaudits the winners of the 2024 Graduate Program Advising and Mentoring Award received in their nomination letters.
“[This professor’s] mentorship is always the perfect balance of pushing you to your full capacity, while also supporting at a level that fosters independence, creativity and self-ownership.”
“[This professor] combines a deep sense of empathy with a steely commitment to student development.”
For many plants, more branches means more fruit. But how does a plant branch or not branch? New research from the Department of Plant Biology has shown how plants break down the hormone strigolactone, which suppresses branching, to become more “bushy.” Using a combination of structural biology, biochemistry, and genetic engineering, the team confirmed the specific enzymes responsible for dismantling strigolactone, and their mechanism. Understanding how strigolactone is regulated could have big implications for many crop plants.
The college is proud to announce the recipients of the 2024 CBS Faculty Teaching and Research Awards. These two prestigious awards honor faculty members who have demonstrated exceptional dedication to teaching and research, and highlight the integral role each plays in advancing the frontiers of biological sciences.
