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.

Excited to share our latest publication! 🎉 Here @sophiezoe.bsky.social reveals an early developmental time window determining initial growth direction of lateral roots. Wonderful collaboration with @wabniklab.bsky.social and @matesf.bsky.social lab www.pnas.org/doi/10.1073/... @cibss.bsky.social

Plants strategically respond to gravity and actively set defined growth angles. These gravitropic set-point angles (GSAs) shape the width and depth...

Any student who sees this: Please do not use ChatGPT to "check links"! Instead, wherever possible use the DOI URL. When there's no DOI, identify the canonical URL and remove any "?" and anything that follows. For example, doi.org/10.1126/scie... not www.science.org/content/arti....

Hi, this is Holden emerging from my Bluesky hiatus to tell everyone that when checking the links in the piece, I used ChatGPT as my search engine (does anyone use Google anymore?). The piece was written by me and edited by humans. So all the links were checked by me and again by our copyeditors.

I was on a 🇩🇪 reviewing board for postdoc fellowships last week. In the past, the 🇺🇸 was always the No. 1 destination across all disciplines. This time, only 10% of applicants aimed for the US. This year the most popular destination was 🇦🇺 (Australia).

Organelle positioning as a principle of metabolic regulation and stress tolerance 🌿🔋🍃 Looking ahead in this joint perspective 🔮 with the Fernie and Sonnewald labs @theplantjournal.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

PERSPECTIVE: organelle positioning as a principle of metabolic regulation and stress tolerance

Understanding how plant cells coordinate metabolism remains a major challenge, particularly at the level of intracellular organization. This perspective proposes that dynamic organelle positioning ac...

A true giant has left us. Widmar Tanner, a pioneer of plant transporter research, has passed away. He was a brilliant scientist, an outstanding mentor, and simply one of the kindest people one could meet. Rest in peace Widmar, and thank you for everything.
