🌍💡Why It Matters? Understanding these evolutionary patterns helps us predict plant responses to climate change and informs conservation of biodiversity hotspots like the Cape Floristic Region.

Lifespan outperforms climate as a predictor of wood functional traits, but secondary woodiness shows no clear climatic pattern in Heliophila, a diverse clade from the Cape Floristic Region

🌍🔍Both scenarios require multiple independent gains and losses of pyrenoids over time, showing how dynamic hornwort evolution has been.

New sunflower family tree reveals multiple origins of flower symmetry

The #sunflower family's intricate evolutionary history, showcases the fascinating phenomenon of convergent evolution. Flower symmetry, a key trait, has independently evolved multiple times within this diverse #plant group. Insights gleaned may aid in breeding plants with desirable traits, benefiting #agriculture & #horticulture.

Image: A new sunflower family tree reveals that flower symmetry evolved multiple times independently. Chrysanthemum lavandulifolium, on the upper left, and Artemisia annua, upper right, are closely related species from the same tribe; the former has bilaterally symmetric flowers — the rays — and the latter does not. Rudbeckia hirta, lower left, from the sunflower tribe has bilaterally symmetric flowers, and Eupatorium chinense, lower right, from the Eupatorieae tribe does not; these two tribes are closely related groups. A sunflower, center, shows flowers with bilateral symmetry — the large petal-like flowers in the outer row — and without bilateral symmetry — the small flowers in the inner rows.

Friend or foe? Researchers explore ancient partnership between moss and fungi

Researchers investigated the intricate interactions between moss, fungi, and endobacteria. Through microscopy and genetic analysis, they discovered that endobacteria within fungi influence their relationship with moss. These findings shed light on fundamental aspects of plant evolution.

A new preprint from the lab testing aspects of a hypothesis that lower chromosome numbers may result from selection to reduce independently assorting incompatibilities. In short, we do not find evidence to support the hypothesis in our analyses. Great work led by PhD student Geoff Finch!

Post-zygotic reproductive isolation is not correlated with chromosome number in plants

🌸The study suggests that Tropaeolaceae TCP4L genes initially played a role in epidermal development, and after a gene duplication event, TCP4L2 acquired a new function in spur initiation and elaboration. (6/6)

Nature’s great survivors: Flowering plants survived the mass extinction that killed the dinosaurs

A new study shows that flowering plants escaped relatively unscathed from the mass extinction that killed the dinosaurs 66 million years ago. Whilst they suffered some species loss, the devastating event helped flowering plants become the dominant type of plant today.

Dynamic plants: Origin & geographic evolution of cycads clarified

Paleobotanist have made an important breakthrough in understanding the origin and geographic distribution of cycads. By combining genetic data with leaf morphological data from both fossil and living species for the first time, the researchers created a phylogenetic tree of these fascinating and endangered plants.

Large Encephalartos are highly prized as ornamental plants, and unfortunately many species have been brought to the brink of extinction by poaching. Credit: Mario Coiro

How fossils may rewrite part of plant evolutionary history

Botanists and paleontologists have identified a fossil chili pepper that may rewrite the geography and evolutionary timeline of the tomato plant family.

Dear colleagues studying #PlantEvolution and #photosynthesis
I try to find out how long the transition from C3 to C4 plants took (range or average of years or generations). I found out how frequently it happened (>60 times), when (30Ma to 7Ma ago) and why. But failed to find any information how long it takes to do the full transition to divergence into a clade. Or is this impossible?

Any help is appreciated. Thanks a lot for boosting!

Well i guess this is really happening… looking forward to reconnecting with community of #PlantEcology, #PlantEvolution, and #Conservation folks on this new platform. Already seeing some familiar faces!
I am a plant ecologist based at #SmithCollege focused on questions around plant conservation and #ClimateChange, with some developing projects exploring #CarnivorousPlants as well as #mycorrhizae. My lab involves mostly undergraduates #PUI and often collaborates w/ #SmithCollegeBotanicGarden.

#HelloWorld... it seems that I'm here now.

I'm a #Bioinformatician from #Portugal.

I've worked on #Genomics, #Proteomics and their sisters meta-, with focus on #PlantEvolution and Aquatic #Microbial #Ecology.

I'm currently working as a #PythonDeveloper on a #Genetics and #Patholofy Lab.
