A novel gibberellin promotes seedling establishment [PDF]
, 2019 A previously unknown biologically active gibberellin present in seeds of Arabidopsis thaliana is formed by hydration of the gibberellin precursor GA12 through the action of GAS2, a 2-oxoglutarate-dependent dioxygenase that decreases sensitivity to ...

Tree Species Vulnerability to Fire Increases at Dry Range Edge
Global Change Biology Communications, Volume 1, Issue 4, December 2026.Following severe drought and fire, some tree species experience increased tree mortality, topkill (death of above‐ground biomass) and lower rates of seedling recruitment at the dry edge of their ranges, while other species maintain resilience, exhibiting low rates of mortality and topkill and high rates of recruitment across their ranges.

Legume Science, Volume 8, Issue 4, December 2026.ABSTRACT Cowpea (Vigna unguiculata L. Walp) is a multi‐use crop highly valued as a food crop, high‐protein fodder, and sustainable cover crop. Yet, it remains underused, and yields in most growing regions are below the crop's potential due to multiple biotic and abiotic stresses.
