🌲 New article in @aobp.bsky.social highlighting how variation among pinyon pine populations could influence forest regeneration and restoration in a warmer, drier future. Full #openaccess 👉 doi.org/rbkn #PlantScience

Seed sources were located at endpoints of range-wide regional gradients of climatic water deficit (CWD; mm) and amount of annual summer precipitation (June through August; mm). CWD is illustrated by a shading gradient from low CWD (wet) to high CWD (dry). Summer precipitation amount is represented by 25-mm contour lines. SB = San Bernardino (arid/summer-dry); MC = Mt. Charleston (arid/summer-wet); SC = Schell Creek (mesic/summer-wet); DM = Desatoya Mountains (intermediate). Inset: Cumulative CWD (mm) and summer precipitation amount (mm) in the four seed sources. The dots represent the mean 30-year climate normal (1990–2019), and the error bars represent the standard error.

🧬 New article in @aobp.bsky.social exploring the origins of herbicide-resistant Brassica rapa in Argentina, showing that resistant and susceptible populations are closely related and that resistance likely evolved through local gene flow and transgene escape. Full #openaccess 👉 doi.org/q5xx

Maximum likelihood tree (RAxML) of 624 Brassica rapa individuals, including 56 Argentinian samples and 568 accessions from around the world. Colours represent different morphotypes and geographic origins, including weedy populations and cultivated forms. Black circles on nodes represent bootstrap support; only values equal or greater than 90% are shown. The pink background highlights a clade that includes weedy forms and some cultivated types (turnip Europe, rapini, grelos), while the light blue background marks a clade containing the remaining cultivated forms. The label ‘Argentina’ identifies the clade that contains all Argentinian samples except those from San Carlos de Bariloche (SCB) and Tafí del Valle (TAFI), which cluster in separate clades labelled ‘SCB’ and ‘TAFI’, respectively.
