Ecology and EvolutionCalligonum species are widely distributed across the arid desert belt stretching from North Africa to Central Asia. Their leaves are nearly fully degraded, and photosynthetic activity is predominantly undertaken by assimilative branches (ABs). Remarkably,

Pest Management Science, Volume 82, Issue 11, Page 10671-10682, November 2026.A 3‐year study across southern Australia aimed to characterize drivers of infection in the Myzus persicae–turnip yellows virus–Brassica napus pathosystem. Identification of key reservoir hosts and the strong association between earlier sowing and increased disease incidence highlight opportunities for targeted weed management, strategic sowing ...

Evolutionary relationship between organellar DNA inheritance patterns and traits of seed plants
American Journal of Botany, Volume 113, Issue 10, October 2026.Abstract Premise In plants, organellar DNA is predominantly maternally inherited, but biparental and paternal inheritance have also been observed. Specific mechanisms, such as plastid exclusion during pollen mitosis or genome degradation, ensure maternal inheritance.

Can DNA from wet, temperate soils be used for palaeoecological reconstruction?
Journal of Quaternary Science, Volume 41, Issue 7, Page 1114-1124, October 2026.ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

Applied Vegetation Science, Volume 29, Issue 4, October/December 2026.This study provides the first integrated evidence of long‐term human impacts in Ethiopia's Bale Mountains, combining modern vegetation transects with sedimentary steroid and bile acid biomarkers. We identified a sharp 200 m settlement edge and reveal sustained anthropogenic influence from the late Pleistocene, with pastoralism intensifying around 6.5 ...

The Plant Journal, Volume 128, Issue 2, October 2026.SUMMARY Specialised metabolism is an important factor in how plants cope with biotic and, to a lesser extent, abiotic stress. Current approaches to identify and study the genes involved in such metabolic pathways mainly leverage genomic and transcriptomic datasets of plants, in order to improve our understanding of plant resilience.
