Chromosome-scale reference genome of <i>Pectocarya recurvata</i>, the species with the smallest reported genome size in Boraginaceae. [PDF]
Appl Plant SciAbstract 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.

Journal of Ecology, Volume 111, Issue 6, Page 1218-1230, June 2023., 2023 Our results demonstrate that soil nutrient‐based species selection is a prevalent driver of community assembly in tropical forests, a process mediated by key functional traits within the leaf and wood economics spectrum. Functional space size and its filling increase with soil nutrient concentration, whereas niche vacancy decreases.
