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

Most evidence is indirect, typically based on the occurence of "leaf mats", which are accumulations of leaves in some sediment layers that suggest seasonality.

Direct evidence can sometimes be seen, by observing if the vascular tissues connecting the leaves to a stem or branch ("leaf traces") end within the first annual ring or cross several rings🪵🍃. But this is dependant on finding specimens with this type of details preserved...
