Nuestra más reciente publicación del lab! El genoma del Toloache

Genomic signatures of the evolution of defence against its natural enemies in the poisonous and medicinal plant Datura stramonium (Solanaceae) Tropane alkaloids and terpenoids are widely used in the medicine and pharmaceutic industry and evolved as chemical defenses against herbivores and pathogens in the annual herb Datura stramonium (Solanaceae). Here, we present the first draft genomes of two plants from contrasting environments of D. s...

Nuestro estudio sobre como la selección natural impuesta por los herbívoros impulsa diferentes respuestas químicas defensivas y moldea la composición genómica de las poblaciones del Toloache esta ya disponible "en prensa" en la revista Evolution. Una larga pero agradable jornada! Muchas gracias a tod@s l@s involucrad@s en este estudio y felicidades!!

Genomic and chemical evidence for local adaptation in resistance to different herbivores in Datura stramonium Since most species are collections of genetically variable populations distributed to habitats differing in their abiotic/biotic environmental factors and community composition, the pattern and stren...

Presentar un cartel en un congreso puede ser o es mucho mejor que una presentación oral, esta nota describe muy buenos puntos sobre esto

Respect the poster Anila began to work on her poster 1 week before the conference. The quality didn't matter that much, she thought. After all, hers would be one in a sea of other boring posters, each nervously guarded by a grad student. “No one is even going to look at it,” she told herself. Anila—a third-year ...

Asymmetry in Herbivore Effector Responses: Caterpillar Frass Effectors Reduce Performance of a Subsequent Herbivore Multiple species of phytophagous insects may co-occur on a plant and while plants can defend themselves from insect herbivory, plant responses to damage by different species and feeding guilds of...

Evolutionary response to herbivory: population differentiation in microsatellite loci, tropane alkaloids and leaf trichome density in Datura stramonium It is thought that natural selection exerted by herbivores on plants has promoted the evolution of plant traits that function as defence. However, such selective pressures may vary spatially...

Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes in the genome. Dissection of the genomic record of sequence change enables broad questions regarding genome evolution to be addressed, even across hyper-diverse taxa within arthropods.

The prevalence, evolution and chromatin signatures of plant regulatory elements By examining chromatin accessibility and modification as well as sequence conservation in 13 plant species, this study characterizes thousands of putative cis-regulatory elements and reveals their prevalence, dynamic evolution and chromatin signatures.
