Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1649-1661, September 2026.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1563-1566, September 2026.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

Relationship between pollen morphology and chromosome numbers in Brazilian species of Lippia L. (Verbenaceae)

open access: yesAnais da Academia Brasileira de Ciências, 2013
The pollen morphology and exine structure of 17 species of Lippia L. were investigated in this work using light and scanning electron microscopy. Among the species studied, 14 showed tricolporate pollen grains, two had tri- and tetracolporate pollen ...

Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1567-1571, September 2026.
Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success
