A transcriptomic hourglass in brown algae - Nature Similar to other eukaryotes, brown algae exhibit transcriptome conservation that is consistent with the molecular hourglass model during differentiation in embryonic development.

Fascinating. Identification of a developmental hourglass in brown seaweed (kelp) in mid embryogenesis, like plants & animals

Suggests evolutionary acquisition of multicelluarity relies on ancient genes that become entrenched early in multicellular lineages

Woodcut with black ink on off-white background. A domestic black cat is prowling through vegetation, exuding the look and feel of her wild ancestors. Her eyes have been left free of all detail, making them appear to glow strikingly with the pure color of the light paper.

Happy National Black Cat Day! Should it be international instead of national? Yes. But I'm not in charge so I can't do anything about it. Woodcut by Eileen Mayo, 1938. collections.vam.ac.uk/item/O726847...

Thermomorphogenesis of the Arabidopsis thaliana Root: Flexible Cell Division, Constrained Elongation and the Role of Cryptochrome Abstract. Understanding how plants respond to temperature is relevant for agriculture in a warming world. Responses to temperature in the shoot have been c

Excited our paper on thermomorphogenesis of root growth has been published! Check it out to read up on how root cell division is flexible, elongation is constrained, and cryptochrome2 has a cool role to play in temperature responses. doi.org/10.1093/pcp/...

Phytochrome-dependent responsiveness to root-derived cytokinins enables coordinated elongation responses to combined light and nitrate cues - Nature Communications The authors here investigate information integration in plants using light and nutrient stimuli and identify a novel regulation pathway towards photoreceptor-regulated stem growth.

Cool new work from Pierre Gautrat and @ronaldpierik.bsky.social in Natcomms on root-to-shoot signaling via cytokinin, regulating shade avoidance responses and nutrient acquisition. So complex! 😱

Will the real Robert Hooke please stand up? Dear Editor,

When I wrote my Short History of Plant Microscopy, I wondered when I couldn't find any reference to 'monk's chambers' in Robert Hooke's "Micrographia". Apparently I'm not the only one who wondered:

The swamp-dwelling ‘bald cypress’ is today’s #SpookyScience feature (and Louisiana’s state 🌲)!

The bald cypress is a pneumatophore, with roots growing just below the surface then protruding ⬆️ (believed to help the tree breathe). The tree’s “knees” don’t always look this spooky, but what a shot 📸 🧪
