Is early always better? Assessing soybean planting date in Minnesota

open access: yesAgronomy Journal, Volume 117, Issue 3, May/June 2025.
Abstract Planting date significantly impacts soybean (Glycine max L.) production in the Upper Midwest. Farmers often plant as early as possible, assuming higher risks and costs, to maximize yield potential. However, in drought‐prone, low‐productivity areas, the benefits of early planting, which are attributed to radiation utilization, could be offset ...

Chromosome‐scale reference genome of Pectocarya recurvata, the species with the smallest reported genome size in Boraginaceae

open access: yesApplications in Plant Sciences, Volume 13, Issue 3, May-June 2025.
Abstract Premise Pectocarya recurvata (Boraginaceae, subfamily Cynoglossoideae), a species native to the Sonoran Desert (North America), has served as a model system for a suite of ecological and evolutionary studies. However, no reference genomes are currently available in Cynoglossoideae. A high‐quality reference genome for P.
