Biodiversity and soil type modulate the effect of plastic contamination on soil functioning

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings show that the negative effects of plastic contamination on soil functioning strongly depend on soil type and can be partly alleviated by plant diversity. In sandy soils, diverse plant communities buffered functional losses under plastic stress, whereas in clayey soils the benefits of diversity were suppressed.

From recognition to response: integrated signaling pathways determining pollen acceptance and rejection in Brassicaceae

New Phytologist, Volume 250, Issue 2, Page 788-798, April 2026.
Summary Generation of competent offspring is vital for the prosperity of flowering plants. The pistil not only functions as a conduit for pollen tubes to grow to the ovary but also provides a selective venue for facilitating the growth of compatible pollen tubes and discouraging invaders and incompatible pollen.

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, Volume 14, Issue 2, March-April 2026.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Alkaloids from

Natural Product Communications, 2011
The alkaloid pattern of the endemic plant Papaver coreanum Nakai (Papaveraceae) was determined for the first time. Eight alkaloids could be identified by LC/ESIMS/MS and high-resolution mass spectrometry.

Orthoquinone, Cyclic, and Acyclic α‐Diketone Natural Products: From Food Applications to Pharmacotherapy

Phytochemicals in Food and Medicine, Volume 1, Issue 1, March 2026.
The orthoquinone metabolites from plants have antimicrobial, antioxidant, antiviral, cytotoxic, and anti‐inflammatory effects. ABSTRACT The structural diversity of natural products is vast and fascinating, and they have been recognized as an enormously diverse source of new lead compounds.

Multiple Glacial Refugia and Complex Postglacial Dynamics of Primula sikkimensis (Primuaceae) in the Heterogeneous Qinghai‐Tibet Plateau

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Primula sikkimensis persisted in distinct glacial refugia within the Hengduan Mountains and eastern Himalayas during the Last Glacial Maximum. Subsequent postglacial range expansions onto the Qinghai–Tibet Plateau were accompanied by secondary contact and interspecific hybridization, collectively enhancing genetic diversity and adaptive capacity. These

First report of Aylax hypecoi (Hym.: Cynipidae: Aylacini) from Iran with some notes on its biology and parasitoids [PDF]

نامه انجمن حشره‌شناسی ایران, 2012
The herb gall wasp, Aylax hypecoi Trotter, is recorded as new for the Iranian cinipid fauna. The specimens were collected from induced galls on fruit-like pods of Hypecoum pendulum L. (Papaveraceae) in Urmia region. The A. hypecoi-H. pendulum association

Highly different flavonol content explains geographic variations in the UV reflecting properties of flowers of the corn poppy, Papaver rhoeas (Papaveraceae).

Phytochemistry, 2020
Papaver rhoeas, the corn poppy, is a very common weed in cereal fields all over the world. Its flowers generally display a bright red coloration, but their reflectance in the ultraviolet (UV) wavelength range varies geographically.

GeneMiner2: Accurate and Automated Recovery of Genes From Genome Skimming Data

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT With the growing accessibility of low cost genome skimming, large‐scale recovery of target genes in non‐model species has become feasible, providing strong data for phylogenomic and evolutionary studies. However, existing tools for data assembly including Read2Tree, HybPiper, and GeneMiner still suffer from computational difficulty and ...

Climate Change and Alpine Screes: No Future for Glacial Relict Papaver occidentale (Papaveraceae) in Western Prealps

Diversity, 2020
Glacial relicts, especially those with very narrow habitat requirements, are particularly affected by global warming. We considered Papaver occidentale, a glacial relict endemic to the Western Prealps, belonging to the alpine poppy complex (P.
