In Situ GWAS in Two Range‐Edge Populations of European Beech (Fagus sylvatica L.) Identify Genetic Factors of Adaptation to Climate Change

Molecular Ecology, Volume 35, Issue 15, August 2026.
ABSTRACT In forest tree populations, the timing of budbreak (TBB) depends on several factors, both environmental and genetic. The genomic architecture underlying this trait is still not fully characterized. So far, common garden experiments have highlighted a few genomic regions with little heritability, while the whole spectrum of TBB variation ...

Phytochemical study of Juglans regia L. leaves

Planta Medica International Open, 2017
A methanolic extract of Juglans regia L. leaves was fractioned by various chromatographic techniques yielding a total of 40 metabolites belonging to megastigmane, tetralone, phenylpropanoid, neolignane and juglone glycosides. Ten unknown megastigmane glucoside derivatives (juglanionosides A-K, 1-10) and six unknown tetralone glucoside derivatives ...

, 2016
Common walnut (Juglans regia L.) is a monoecious, herkogamous, anemophilous, heterodichogamous and autofertile plant. Study of the sexual cycle of the walnut is hindered by the presence of a relatively long juvenile period and high genetic diversity ...

Beneath the Bark: Molecular Determinants of Adaptation and Infection in Bacterial Pathogens of Woody Hosts

Molecular Plant Pathology, Volume 27, Issue 8, August 2026.
Bacterial pathogens colonise woody hosts by integrating metabolic adaptation, effector‐mediated immune suppression, cell wall remodelling and EPS‐ and toxin‐supported persistence. ABSTRACT Bacterial pathogens of woody plants represent a pervasive yet underexplored threat to global agriculture and forestry, causing devastating diseases in fruit trees ...

Molecular evolution of terpene synthase underlying the diversification of isoprene emission in Fagaceae

Plant Biology, Volume 28, Issue 5, Page 1315-1329, August 2026.
Isoprene emission in oaks originated from convergent adaptive evolution of terpene synthases, involving a substrate shift from monoterpene to isoprene production within a Fagaceae‐specific TPS lineage. Abstract Plants emit a wide range of volatile organic compounds, among which isoprene is the most abundant and atmospherically influential. Although oak

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

Advanced Science, Volume 13, Issue 38, 9 July 2026.
This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...

Simulating past and future refugia for temperate trees in northern Italy

Ecography, Volume 2026, Issue 7, July 2026.
During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large‐scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost ...
