Congratulations @penlindsay.bsky.social 🥳☀️

🌱 Using ‘compelling’ methods, including #CryoET, researchers mapped spinach thylakoid membranes at single-molecule precision, revealing how photosynthetic complexes are organised and settling long-standing debates on chloroplast architecture.

The image shows one straight magenta line and, close to it, another wavy green line.

This might be one of the simplest images I captured, but very fascinating nonetheless, as it shows how tight the cytoplasm in a plant cell is. The cytosol and all other organelles are squished between the plasma membrane (magenta) and the central vacuole (its membrane is green)

Hormonal regulation of cell fate plasticity of xylem-pole-pericycle lineage in Arabidopsis roots In Arabidopsis roots, xylem-pole-pericycle (XPP) cells exhibit dual cell fates by contributing to both lateral root (LR) and cambium formation. Despit…

🌱 What happens when lateral root primordia (LRPs) fail to emerge?
Using our new lineage tracing tool LRTracker, Xin discovered that arrested LRPs don’t just disappear—they gradually switch fate and become part of the cambium, contributing to secondary growth.1/x

Trimezia coerulea from South America is pollinated by oil-collecting #bees. The flowers have oil-secreting trichomes (hairs) – you can see them glistening with oil if you zoom in on the circled area. #oil #bees #pollination #Iridaceae #TropicalBotany #Botany 🌾🧪🌱

Actin perturbation disrupts the alignment between the PPB and the division site.

Time-lapse analysis of dividing trichoblast in root expressing the microtubule reporter IQD8-GFP (green) and the plasma membrane marker 2xmCh2xPHFAPP1 (magenta), after 2h-LatB.

🌱✂️ How do plant cells decide where to divide?

Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.

Would you consider the root apical meristem (RAM) pluripotent or multipotent? RAM can generate multiple tissues of the root, but pretty much just root. So it’s more similar to multipotent stem cells rather than pluripotent stem cells that can develop into multiple organs. Thoughts?

Common #milkweed, #Asclepias syriaca, named by #Linnaeus as he thought this was the same as Calotropis from the Middle East. Now in #flower in #Ithaca. Dark spots on the flowers are part of wishbone-shaped pollinia, packages of pollen; orchids & milkweeds make them instead of free pollen grains
