Environmental associations and spatial segregation among coexisting Pogonomyrmex harvester ant species in the central Monte desert (Argentina)

Abstract Background Ant communities are widely considered to be structured by interspecific competition. Seed-harvesting ants are dominant granivores in drylands, and their colony locations influence their spatio-temporal effect on plant communities. Three closely related species...

A pair of duplicated SOC1 genes, DcSOC1-1 and DcSOC1-2, control vernalization requirement in carrot

Abstract Background Carrot vernalization requirement (VR), the amount of cold exposure needed for plants to become vernalized, strongly influences geographical adaptation of the crop and many agricultural practices, and this trait defines annual vs. biennial cultivars. Despite it...

Plastome convergence across endoparasitic plant lineages: genome reduction, high AT bias, elevated substitution rates, and functional persistence in Mitrastemon yamamotoi

In heterotrophic plants, the loss of photosynthesis is often associated with plastid genome (ptDNA) reduction, although the extent of genome decay varies widely among lineages and may culminate in complete genome loss. Of the multiple transitions to heterotrophy among angiosperms...
