I am honored. So many of my scientific heroes are ASCB fellows. Thanks to my nominators, my mentors, and to UC Davis ASCB fellows Mark Winey, Jon Scholey, and Jodi Nunnari. But thanks most to all those who have done science with me, @gwgl.bsky.social and all the graduate students and postdocs

We are deeply saddened to share that Michael Freeling passed away on 7/20/2026 after a year-long battle with cancer. Our deepest condolences go to his family, friends, colleagues, and the many students he inspired. We will share additional memorial information soon.

We are very sorry to share the sad news that Michael Freeling passed away on 7/20/2026 after a year long battle with esophageal cancer. Mike was a long-time faculty member in the Plant and Microbiology Department at University of California-Berkeley, a groundbreaking plant geneticist, and an inspiring teacher and mentor to over two dozen Ph.D. students, four dozen postdocs, and countless undergraduates. He was best known for pioneering work on maize anaerobic metabolism and gene regulation, transposon biology, developmental genetics of the maize ligule, and the discovery of biased gene retention following whole-genome duplications in plants. Mike was hired by UC-Berkeley as an assistant professor straight out of graduate school in 1973, and he was promoted to Associate Professor in 1979 and to full professor in 1984. He was selected as a Guggenheim Fellow in 1980, elected to the National Academy of Sciences in 1994, and won the McClintock Prize for Plant Genetics and Genome Studies in 2017. Mike taught genetics, comparative genomics and scientific reasoning to our graduate students, and he also taught a popular genetics course for non-majors that had various titles over the years but was affectionately known as “Genetics for Poets.” Our deepest condolences go out to his family, friends and many colleagues.

One of our recent papers describing techniques to identify root barriers to parasitic plant infection. Plus we show that lignin in the cortex can block branched broomrape infection of tomato.

Hairy link... Gouran et al. @bradylabs.bsky.social @plantdevo.bsky.social provide an integrated experimental framework that enables holistic analysis of broomrape parasitism, which may be applied at scale to accelerate resistance gene discovery in #tomato & other hosts 🔗 doi.org/10.1093/pcp/...

4 images showing cellular resolution assessment of broomrape infection in tomato hairy roots. two top panels (a & b) show confocal microscopy of the tomato–broomrape interface. two bottom panels (c & d) show cleared tomato hairy roots with an attached broomrape seedling. Images taken from Figure 3, Mona Gouran, Moonglow S De Clarin, Siobhan M Brady, Neelima R Sinha, An integrated framework to elucidate mechanisms underlying host-branched broomrape infection, Plant and Cell Physiology, Volume 67, Issue 4, April 2026, Pages 605–613, https://doi.org/10.1093/pcp/pcaf161

Several folks noted this was unfair. some other unis also don’t top off or require PIs to. Also all the PIs I know are doing their best to resolve this. So perhaps instead of “don’t come to UCD” i should have said “make sure you figure this out no matter where you’re going”.

UC Davis will no longer pay the difference so that GRFP recipients earn the same as other students. So mid-PhD students will lose nearly 25% of salary & new students will make less than their peers. Apply for the GRFP, it’s a wonderful help to your career. Just don’t come here if you get one.

This study identifies epidermal patterning factor (EPF)-processing proteinases as the key activators of EPF1 and EPF2 peptides, establishing their proteolytic processing as the critical missing link f...

Adult monarch butterflies (Lepidoptera: Nymphalidae: Danaus plexippus) will feed on nectar from many different flowers but their larvae specifically need to eat milkweeds (Apocynaceae: Asclepiadoideae) in order to develop properly. Pictured Rocks National Lakeshore, Michigan, 13 Jul 2026.
