New paper on phenotypic plasticity

New paper on phenotypic plasticity

A new paper from our working group has just been published in New Phytologist journal. In this study we examine the role of phenotypic plasticity in the evolutionary processes of convergence and divergence, and we have done this by focusing on the Brassicaceae plant family. For this, in addition to the work we are developing with our Moricandia study system, we have added an enormous revision work on the characterization of floral traits and pollination systems in the Brassicaceae family. Our knowledge of this important plant family is now much better!

The title is “Phenotypic plasticity guides Moricandia arvensis divergence and convergence across the Brassicaceae floral morphospace“.

Although our work is not about cosmic wormholes, it is true that something has inspired us…

Volvemos a las reuniones “Face-to-face”…

Volvemos a las reuniones “Face-to-face”…

Finalmente hemos podido volver a las reuniones de trabajo personales. Durante dos fines de semana del pasado mes de septiembre los miembros del grupo Evoflor nos hemos podido reunir en el incomparable marco del
Parque Nacional de la Sierra de las Nieves (Málaga) para mantener sendas reuniones de coordinación. Este precioso entorno natural, unido a las ganas que teníamos de volver a vernos las caras, ha favorecido las discusiones y debates intensos, producto de las cuales hemos sido capaces de sentar las bases de la que será nuestra propuesta de proyecto en la siguiente convocatoria del Plan Nacional de I+D y hemos esbozado el siguiente manuscrito que enviaremos a publicar lo antes posible.

Se echaban de menos las reuniones “físicas” para poder recuperar las sesiones maratonianas de discusiones de trabajo sin las distracciones del “modo virtual”.

La verdad es que… es mucho más agradable y productivo volver al trabajo viéndonos las caras “en real”. A ver si esta “pesadilla” pandémica se termina y podemos volver a las rutinas en las que nos desenvolvemos más eficientemente.

Cuando en el año 2008 comenzamos a elaborar vídeos de animación para transferir al conjunto de la sociedad la información publicada en los artículos científicos que escribíamos, uno de los objetivos era trasladar esta información de manera rápida y comprensible a un público no familiarizado con nuestro trabajo de investigación. La realidad nos ha puesto en nuestro sitio y … resulta que no somos capaces de hacer el trabajo de divulgación científica en paralelo al de investigación. Han tenido que pasar unos meses desde la publicación de nuestro estudio sobre plasticidad fenotípica y nicho de polinizadores*, pero… ahora, por fin, podemos mostraros el vídeo que hemos preparado para tratar de incrementar la difusión social de este estudio. Poned pantalla grande, dadle volumen y … disfrutadlo cómo lo hemos hecho los autores con el trabajo realizado.

En este vídeo mostramos qué es la plasticidad fenotípica y cómo la plasticidad individual dentro de las flores de Moricandia arvensis (Brassicaceae) permite a esta especie de planta modificar su nicho de polinización.

Phenotypic plasticity, climate change and pollinators

A drastic change in floral phenotype causes the same plants to attract different pollinators and reproduce in harsh climates

Phenotypic plasticity is the ability of a genotype to produce different phenotypes in response to changes in the environment. This is an essential property of living beings but its role in adaptation and acclimatization to environmental changes is not yet fully known.

As part of a truly multidisciplinary team of researchers from the Experimental Station of Arid Zones (CSIC) and the Universities of Granada, Vigo, Pablo Olavide and Rey Juan Carlos, we have just published an article in the top-ranking journal Nature Communications demonstrating experimentally, both in natural conditions and in the laboratory, the phenotypic plasticity of the flowers of a plant species living in semi-arid environments.

A comparison of the different flower phenotypes this plant produces in spring (left) or harsh summer (right) conditions (Photo by F. Perfectti).

In spring, this species – the crucifer Moricandia arvensis – produces large, lilac-colored, UV-reflecting flowers in the shape of a cross. These flowers attract mainly large, long-tongued bees as pollinators. However, unlike most coexisting species, M. arvensis maintains flowering during the dry, hot summer of the western Mediterranean. This is due to its plasticity in key vegetative traits, including photosynthetic traits, that adjust its metabolism to these extreme temperatures and water deficit conditions. The summer’s high temperatures and longer light hours trigger changes in the expression of more than 625 genes in the flower that lead to these plants to produce different radical flowers. Whereas in spring flowers were large and cross-shaped, in summer they are small and rounded; whereas they were lilac and reflected UV, in summer they are white and absorb UV. These summer flowers attract a different set of pollinators composed of more generalist species. This change in the pollinator set (the pollination niche) allows this plant to reproduce successfully under the challenging summer conditions. Phenotypic plasticity for flower, vegetative, and photosynthetic traits seems to allow M. arvensis to cope with anthropogenic disturbances and climate change.

The phenotypic plasticity exhibited by individuals of the Moricandia arvensis plant promotes the production of large, lilac-colored, cross-shaped flowers that reflect UV and attract mainly large long-tongued bees in spring and smaller, rounded white flowers, which absorb UV, in summer, when environmental conditions are difficult for many organisms to survive. These «summer» flowers are visited by generalist pollinators and this allows the plant to continue to reproduce when environmental conditions are harsh.

New paper published: Kin discrimination allows plants to modify investment towards pollinator attraction

New paper published: Kin discrimination allows plants to modify investment towards pollinator attraction

Two Evoflor’s members (José María Gómez and Rubén Torices) in collaboration with John Pannell from University of Lausanne have recently published a paper in Nature Communications showing that the self-incompatible monocarpic Moricandia moricandioides can adjust its flowering behaviour to the surrounding intraspecific social environment.
