The 5th Annual PCA Core Network Participant (CNP) Meeting took place this past weekend in St. Louis, MO! It was a great opportunity to celebrate accomplishments from the past year, connect with colleagues from across the network, and discuss the next phase of the PCA.
PCA Members are excited to share our new paper, which outlines a roadmap for tracing the origins & diversification of cell types across green plants using single-cell technologies. From algae to angiosperms, we're entering a new era of comparative cell biology. bit.ly/4eAip2Q

These epidermal cells of tobacco (Nicotiana benthamiana) leaf are expressing cytosolic GFP. The brightest region is the nucleus, which is surrounded by a large central vacuole. The cytosol is restricted to the cell periphery. Transvacuolar strands connect the nucleus with other parts of the cell.

This is a section of juvenile moss (Physcomitrium patens) tissue, called protonemata. The apical cells expand by tip-growth, while subapical cells sometimes divide to make lateral filaments. Cytosolic GFP is in green, and chlorophyll autofluorescence is in magenta. #microscopymonday #moss
An undergraduate student in the lab, Andy Marchant, made this awesome image of a moss (Physcomitrium patens) apical chloronema cell. This is a beautiful example of how the ER network looks in plant cells (in green). The chlorophyll autofluorescence is in magenta. #microscopymonday #moss

🌱💚🎉 Sharing (again 😁) my review on regulation of chloroplast biogenesis. First work of my emerging research group at @cbgpmadrid.bsky.social
Journal of Experimental Botany@jxbotany.bsky.social · 5mo ago🌿🟢 REVIEW 🟢🌿 This review focuses on recent advances in chloroplast biogenesis and chromoplast differentiation, with emphasis on transcriptional regulation, and identifies areas where further progress is needed – Hernández-Verdeja 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪
I pulled this image from the archives of my PhD work, back when I was working with plant and yeast mitochondria. These are two Arabidopsis guard cells, with their cytosol in magenta, mitochondria in yellow, and chlorophyll autofluorescence in green. #microscopymonday, #plantcells, #guardcells
Moss (Physcomitrium patens) protoplasts (wallless cells) transformed with chloroplast envelope protein tagged with mGFP (green). The chlorophyll autofluorescence is in magenta. The protrusions of the chloroplast envelope are called stromules. #microscopymonday, #plantcells, #plantmicroscopy, #moss
Surface (epidermal) cells of many plants are shaped like jigsaw puzzle pieces. 🧩 These are epidermal cells of tobacco (Nicotiana benthamiana) expressing cytosolic EGFP. The bright spherical structures are cell nuclei. #microscopymonday, #plantcells, #plantmicroscopy

We were testing lasers and the spectral ability of our confocal (FV3000) on a zoomed-in section of a Brassica rapa leaf. But when we zoomed out, we saw that the lasers we used photobleached chlorophyll autofluorescence in the square area we had zoomed in on. We used a 10x/0.4 objective for this.
These Brewer's yeast cells were in a hurry! This was captured with a point-scanning confocal microscope, which scans one point (pixel) at a time, moving from left to right and top to bottom. As a consequence, cells moving faster than the scan speed appear as streaks or exhibit distortions.

Happy New Year, everyone. For this #microscopymonday, here is a moss (Physcomitrium patens) protoplast (wall-less cell) transformed with a nuclear marker (in magenta). The much brighter area is the nucleolus. The chlorophyll autofluorescence is in green. #moss #plantcells
Today I made a small but momentous start to work in 2026 by changing a single number. I renamed the file “Papers to write and submit in 2025” to “Papers to write and submit in 2026”. Stay tuned for more file updates on 1st January 2027.

A crucial step towards understanding tip growth in plants. Ivan Radin @radinbio.bsky.social (University of Minnesota) highlights work from Ryken et al. of the Bezanilla lab (rupress.org/jcb/article/...) in Spotlight: rupress.org/jcb/article/... #CellSignaling #PlantBiology #PlantCellBiology
These close-ups of mucilage-covered tentacle tips from the leaf of a carnivorous sundew plant (Drosera spatulata) definitely have a strong holiday vibe, so I am posting them just in time for the holidays. Happy Holidays. #microscopymonday #carnivorousplants
Spotlight: Ivan Radin discusses new work from Ryken and colleagues (rupress.org/jcb/article/...) which shows how localization and function of autoinhibitory calcium ATPases maintains the strength of the tip-focus Ca2²⁺ gradient during polarized plant growth. rupress.org/jcb/article/... #PlantBiology
This is what happens to the moss (Physcomitrium patens) chloroplasts when we grow cells on β-lactam antibiotics. β-lactams inhibit the synthesis of the peptidoglycan in the chloroplast envelope, leading to their dramatic expansion. #microscopymonday #moss #plantcells #plantmicroscopy 1/3
