Biofertilization of canola seeds with Peribacillus simplex and Paenibacillus polymyxa bacteria increases tocopherol content

open access: yesJSFA reports, EarlyView.
Abstract Background Biofertilization with plant growth‐promoting bacteria (PGPB) is a reliable strategy to reduce the amounts of chemical fertilizers applied to crops. Nevertheless, the effects of biofertilizers on plant chemical constituents that influence food quality and human health should be evaluated.

Genome‐Wide Assessment Reveals Ancestral Differences in Homozygosity Patterns Potentially Linked to Parkinson's Disease Etiology

open access: yesMovement Disorders, EarlyView.
Abstract Background Recessive genetic variation and extended runs of homozygosity (ROHs) may contribute to the unexplained heritability of Parkinson's disease (PD), particularly in diverse and understudied populations. Objective We conducted the first large‐scale, multi‐ancestral investigation of PD to examine the impact of genome‐wide homozygosity on ...

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

open access: yesNordic Journal of Botany, EarlyView.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...
