Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

Distinct Immunomodulatory Strategies Guide Mesenchymal Stromal/Stem Cell‐Mediated Bone Regeneration

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
Bone regeneration by mesenchymal stem cells is strongly influenced by immune signals. This study shows that priming stem cells with regulatory immune cells or an inflammation‐resolving lipid molecule enhances bone formation through distinct immune pathways.

Genetic Diversity, Population Structure, and Environmental Influences in Nepeta glomerulosa: Implications for Conservation in the Irano‐Turanian Region

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Nepeta glomerulosa shows moderate genetic diversity with three main clusters and significant admixture, highest in the Alborz Mountains, suggesting it may be the center of origin. High genetic differentiation (Gst = 0.4199) points to limited gene flow and possible self‐pollination, with geographic isolation shaping population structure.

Genomic Insights Into Species Divergence and Adaptive Evolution in the Grass Genus Orinus on the Qinghai‐Tibet Plateau

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Using population genomic data, we investigated the evolutionary history and genomic divergence of closely related terrestrial plant lineages to test whether speciation proceeded in the presence of gene flow. Demographic modeling and genome‐wide scans revealed divergence with ongoing gene flow, heterogeneous genomic differentiation, and signatures of ...
