Flower heterochrony and crop yield Crop improvement has focused on enhancing yield, nutrient content, harvestability, and stress resistance using a trait-centered reductionist approach. This has downplayed the fact that plants are deve...

Hypothesized scenario for how ecological change (sensu Stebbins, 1970) may initiate evolutionary pollinator shifts, using colonization of novel environments with altered pollinator communities as stand-in for ecological change, and shifts from bee to hummingbird pollination as example for evolutionary pollinator shifts.

Ecological change may be a common initiator of evolutionary pollinator shifts

Cuando la soja necesita ayuda: el rol inesperado de los insectos Un estudio muestra que este cultivo no siempre se autofecunda como se creía. En ciertas condiciones, depende de polinizadores para sostener la formación

Qué lindo cuando la línea de trabajo que te apasiona (y que pensabas que no le interesaba a nadie) puede desafiar preconceptos en el agro. Consulta este link para ver cómo conocimientos básicos de desarrollo en flores pueden dar respuestas en el ámbito aplicado.

Presentando mis últimos trabajos en el congreso de ESEB, donde propongo puentes entre evolución del desarrollo floral, polinizacion y mejoramiento de cultivos 🫛🌾

Contenta de participar en el congreso de la sociedad europea de evolución (ESEB) 2025. Este lunes estuve presentando trabajos sobre evolución del desarrollo floral que llevamos adelante en el labo de Biología Floral del IMBIV (UNC-CONICET). 🌺

Cerrando CLEVOL II con el labo

Contenta de participar en el segundo congreso latinoamericano de biología evolutiva, CLEVOL II, hablando acerca de competencia entre granos de polen y selección sexual en plantas con flores. Sigamos promoviendo la biología evolutiva en la región!!

A space for time. Exploring temporal regulation of plant development across spatial scales Developmental timing in plants is tightly regulated at the whole-organism scale, from germination to flowering. Less is known about when and how local transitions are temporally regulated. Not every ...

Our lab's first review article written with @yadhusankar.bsky.social and @vijayalakshmi.bsky.social is out now in The Plant Journal! 🎉🌱

We discuss temporal regulation of (plant) development. When and how do plants control organ and cell identity progression?

All About Ferns, with Dr. Emily Sessa of NYBG | joegardener® Evolutionary biologist Dr. Emily Sessa of the New York Botanical Garden in the Bronx teaches us all about ferns.

Dr. Emily Sessa, researcher & Director of the NYBG Herbarium, delves into the unique biology & history of ferns on this episode of the Joe Gardener Show podcast. She describes the ferntastic 🌿 world of "underdog plants" further in her book, linked below! #NYBGscience joegardener.com/podcast/all-...

Within-species floral evolution reveals convergence in adaptive walks during incipient pollinator shift - Nature Communications During evolution, how adaptive walks cross fitness valleys remains unclear. This integrative study on monkeyflowers reveals that convergence in large steps (floral color and gene expression) drives a ...

Really excited to say that my lab's paper on color transitions in Mimulus sect. Erythranthe is out! We found that some traits demonstrate evolutionary convergence in phenotype & genotype, while others are divergent, & that - as Bob Vickery found - bees prefer yellow!

Pictures of the flower heads of 15 species of summer-flowering Mediterranean thistles

Despite experiencing high summer temperatures, the interior of the capitula of 15 species of Mediterranean thistles blooming during the hottest time of year was substantially cooler than the air most of the time.

deposited pollen exploding out of a flower when pollinated again

"Pollen Wars: Explosive Pollination Removes Pollen Deposited from Previously Visited Flowers"
Anderson et al. find that explosive pollination may confer a pre-pollination, male-competition advantage to plants.

This research synthesizes my perspective on how plant developmental biology, particularly heterochrony, can be applied to crop improvement.
