Thrilled to have our paper out in @science.org. Cell division guides plant cell wall formation. Does the reverse hold? We show that bimodal pectin methylesterification, via PME5 mRNA nuclear sequestration, influences plant cell division and cell plate orientation. www.science.org/doi/10.1126/...

Out in @science.org this week:
PME5 is sequestered in the nucleus and released during cytokinesis allowing its activity to be timed with cell division.

🍀🔬 Unpublished data from the lab!

The power of doing hardcore genetics, development, and cell biology using plant as model system!

In the movie, you will see the primary root tip (magenta arrow) and lateral root (yellow arrow) coiling constantly in the same way over 3 days.

New Current Biology study from @minyaaa.bsky.social and colleagues shows how early CYC expression patterns establish dorsal identity in Mimulus parishii meristems. A clear step forward in understanding floral symmetry and developmental evolution. 🧪 🧪

My grad student, @ohazel.bsky.social Olivia, started her Scanning Electron Microscope (SEM) exploration recently.

This is the first of many SEM images shared by us. More to share in coming days... 🔬🔬🔬

No Two Plants
YouTube video by Nora Jane Long No Two Plants

A little over a year ago, I co-directed a short film as part of the Symbiosis Film competition, called "No Two Plants". I was paired with a filmmaker and we had a week to make a short film. I also made the score for the film.

I'm sharing it here, please enjoy!

This is the danger of shortcut pretty images. After 5-10 years, when we will look back, we will find everything looks like same.
