From ice age to present: Clonal expansion & genetic variation in the world's oldest #conifer stand New #AJB research by James Marthick, Andrew Phipps, Gregory Jordan, Daiki Takahashi, Yoshihisa Suyama & James Worth doi.org/10.1002/ajb2... #botany #plantscience #genetics
In vitro propagation of woody semi-mangrove species is often constrained by explant contamination, browning and stage-specific morphogenic responses. The authors examined how explant developmental state, basal-medium strength and plant growth regulators affected in vitro establishment and regeneration responses in Heritiera littoralis.

Describing the cones & seeds of extinct #conifer species---using CT and 3D visualization---that co-existed with the dinosaurs 150 million years ago in what is today the state of Utah. New #AJB research by @mariahmhowell.bsky.social et al. doi.org/10.1002/ajb2... #botany #paleobotany #fossils
Using an industrial-strength CT scanner, the authors of this study were able to look inside a new species of a 151-million-year-old conifer cone from Utah to see the three spirals of seeds preserved inside, without having to cut open the precious fossil.

Interesting fungal find: This parasitic plant fungus (Exobasidium karstenii) lives exclusively on bog-rosemary (Andromeda polifolia) and makes some of the leaves much broader, and purple. The green and the purple leaves here are the same plant! #naturephotography #fungifriends

This week, let’s look at plants with skirts. 💃 The “skirts” are the dried, dead leaves that some plants retain rather than drop. The Cuban petticoat palm, Copernicia macroglossa, is a classic example. #Arecaceae #Botany 🌾🧪🌱

Double Claw is the apt common name for the fruit of Proboscidea parviflora. When green, the fruits look like okra, but the epicarp is shed & the two carpels separate, forming a double claw that hooks onto passing legs & feet. 📷: Franck Carey CCBYNCSA2 #Martyniaceae #epizoochory #Botany 🌾🧪🌱
Collage of two photos. The upper photon shows dried fruits among dried grass. The capsular fruits have two long, curved processes like calipers. The lower photo shows how, when the fruit is trod upon, the springy arms of the caliper-like fruit clasp an animal, in this case, a human wearing a hiking boot.
