Host preferences of non‐native Acalolepta aesthetica (Coleoptera: Cerambycidae) on the Island of Hawaiʻi

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 2, Page 149-159, May 2026.
Acalolepta aesthetica is a non‐native cerambycid established on the Island of Hawaiʻi. We show its preferred hosts are woody species that are highly valued for agricultural, horticultural and cultural uses. We used a resource selection function to estimate host preferences and found that kukui (Aleurites moluccanus), the state tree, was preferred ...

The parenchymo-vascular cambium and its derivative tissues in stems and roots of Bougainvillaea glabra Choisy (Nyctaginaceae)

open access: yesActa Societatis Botanicorum Poloniae, 2015
In the shoots and roots of Bougainmllaea, the parenchymo-vascular cambium produces thinwalled secondary parenchyma to one side and the secondary vascular bundles embedded in the "conjunctive tissue" to the other.

Reduced snow cover at the alpine treeline: resistance and recovery of saplings

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1492-1509, May 2026.
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

WUSCHEL Transcription Factor: From Stem Cell Maintenance to Crop Improvement

open access: yesAdvanced Science, Volume 13, Issue 24, 27 April 2026.
This review synthesizes emerging insights into WUSCHEL (WUS) as a central regulator of plant stem cell fate beyond Arabidopsis, highlighting its roles in regeneration, somatic embryogenesis (SE), and stress adaptation across crops. It explores how WUS‐centered regulatory networks, genome editing, and AI‐guided strategies can be leveraged for precise ...

Germin and germin-like proteins: evolution, structure, and function [PDF]

open access: yes, 2008
Germin and germin-like proteins (GLPs) are encoded by a family of genes found in all plants. They are part of the cupin superfamily of biochemically diverse proteins, a superfamily that has a conserved tertiary structure, though with limited similarity ...

Functional and Phylogenetic Implications of Canopy Mesophication in Temperate Hardwood Forests

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Mesophication describes the shifting of forests fire‐adapted systems to those dominated shaded‐adapted species, but the functional underpinnings of forest mesophication have received less quantitative testing. Using 20th century legacy datasets of changing forest composition in Wisconsin, USA, we characterized broad declines in drought tolerance, fire ...

Changes in cell/tissue organization and peroxidase activity as markers for early detection of graft incompatibility in peach/plum combinations [PDF]

open access: yes, 2010
9 páginas, 3 figuras, 4 tablas -- PAGS nros. 9-17Changes in cell and tissue organization and in peroxidase activity have been analyzed to find early markers to predict graft incompatibility occurrence in peach/plum combinations (Prunus persica/Prunus spp.

European Ash (Fraxinus excelsior) as a Functional Keystone Species Shaping Woodland Flora in the UK

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Ash trees have distinct ecological attributes—their canopy allows a high level of light to penetrate and their foliage decomposes rapidly. Here we used woodland survey data to explore if the prevalence of ash trees has an impact on associated plant communities at a fine spatial scale.
