Effect of seed circulation systems on the spread and diversity of Xanthomonas phaseoli pv. manihotis infecting cassava crops of the Colombian Caribbean

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 353-364, January 2026.
Cassava is a lifeline for millions of people across the tropics, but its productivity is at risk from a disease called Cassava Bacterial Blight (CBB). In this study, we explore how the everyday practices of farmers exchanging cassava cuttings—a long‐standing tradition—can shape how the disease spreads and evolves in the Colombian Caribbean.

Climate and hybridization shape stomatal trait evolution in Populus

open access: yesNew Phytologist, Volume 249, Issue 2, Page 792-809, January 2026.
Summary Stomata play a critical role in regulating plant responses to climate. Where sister species differ in stomatal traits, interspecific gene flow can influence the evolutionary trajectory of trait variation, with consequences for adaptation. Leveraging six latitudinally distributed contact zones spanning the natural hybrid zone between Populus ...

Integrating target capture with whole genome sequencing of recent and natural history collections to explain the phylogeography of wild‐growing and cultivated cannabis

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1771-1788, November 2025.
Cannabis has been used by humans for millennia, resulting in diverse landraces and uses. Its complex legal status and economic importance make sampling wild‐growing populations difficult, limiting past studies to modern cultivars with low genetic diversity. Our research provides crucial insights into the genetic diversity of wild‐growing and cultivated

Genomics and morphometry of herbarium specimens elucidate the origin of the Cape Verde date palm (Phoenix atlantica A.Chev.) and highlight its agronomic potential

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1358-1371, September 2025.
As climate change accelerates, breeding resilient crops is urgent. The date palm (Phoenix dactylifera L.), a crucial 18 billion USD fruit crop, underpins North African and West Asian oasis agroecosystems. This study investigates the genetics and morphology of its closest wild relative, the endemic and endangered Cape Verde date palm (Phoenix atlantica ...
