The chromosome-scale genome and the genetic resistance machinery against insect herbivores of the Mexican toloache, Datura stramonium
Abstract
Abstract Plant resistance refers to the heritable ability of plants to reduce damage caused by natural enemies, such as herbivores and pathogens, either through constitutive or induced traits like chemical compounds or trichomes. Howeve...

Nuclear and chloroplast DNA phylogeography reveals high genetic diversity and postglacial range expansion in Quercus mexicana.
Abstract
PREMISE
Phylogeographical studies are fundamental for understanding factors that influence the spatial distribution of genetic lineages within species. Population expansions and contractions, distribution shifts, and climate changes are...

Inter‐annual variation in the abundance of specialist herbivores determines plant resistance in Datura stramonium
Abstract
Abstract The expression of plant resistance traits against arthropod herbivores often comes with costs to other essential plant functions such as growth and fitness. These trade‐offs are shaped by the allocation of limited resources. Ho...

Long-distance dispersal drives the genetic variation and historical demography of Quercus magnoliifolia and Quercus resinosa (Fagaceae) in the Mexican highlands
Abstract
While hybridization and introgression can have a strong adaptive importance, it can impede divergence of species. Quercus magnoliifolia and Q. resinosa are two endemic oak species distributed across the Mexican highlands. These species ...

A Trip Back Home: Resistance to Herbivores of Native and Non-Native Plant Populations of Datura stramonium
Abstract
When colonizing new ranges, plant populations may benefit from the absence of the checks imposed by the enemies, herbivores, and pathogens that regulated their numbers in their original range. Therefore, rates of plant damage or infesta...

Comparative transcriptome profiling reveals distinct regulatory responses of secondary defensive metabolism in Datura species (Solanaceae) under plant development and herbivory‐mediated stress
Abstract
Abstract Differential expression of genes is key to mediating developmental and stress‐related plant responses. Here, we addressed the regulation of plant metabolic responses to biotic stress and the developmental variation of defense‐r...

Gene family evolution and natural selection signatures in Datura spp. (Solanaceae)
Abstract
Elucidating the diversification process of congeneric species makes it necessary to identify the factors promoting species variation and diversification. Comparative gene family analysis allows us to elucidate the evolutionary history o...

Genomic signatures of the evolution of defence against its natural enemies in the poisonous and medicinal plant Datura stramonium (Solanaceae)
Abstract
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 d...

Tropane alkaloids and terpenes synthase genes of Datura stramonium (Solanaceae)
Abstract
Background Plants have evolved physical–chemical defense to prevent/diminish damage by their enemies. Chemical defense involves the synthesis’ pathways of specialized toxic, repellent, or anti-nutritive metabolites to herbivores. Molecu...
