Nuclear DNA of plastid origin (NUPTs), neglected driver of genome variation and evolutionary innovation

The Plant Journal, Volume 125, Issue 3, February 2026.
Significance Statement Contrary to expectation, NUPTs do not necessarily have a deleterious or ultimately neutral impact, nor are they necessarily purged from the genome. Instead, they can proliferate and eventually become fixed, generating new and novel genes, gene regions and regulatory elements, thereby significantly contributing to plant nuclear ...

Development and Characterization of Copaiba Oil‐Loaded Polymeric Nanocapsules With Enhanced Antitumor Activity Against Breast Cancer Cells

Particle &Particle Systems Characterization, Volume 43, Issue 1, January 2026.
The present study developed and characterized a novel copaiba oil polymeric nanoparticle (NPOC), which was efficiently internalized by breast cancer cells, exhibited greater cytotoxicity and selectivity than free copaiba oil and standard drug doxorubicin. NPOC also reduced tumor growth and migration in 3D models.

Synchrony strategies of six gall inducers that share a superhost, Eugenia copacabanensis (Myrtaceae)

Plant Biology, Volume 28, Issue 1, Page 225-239, January 2026.
Galling insects on the superhost Eugenia copacabanensis have developed different life cycle strategies to synchronize with plant seasonal changes and avoid competition for resources. Abstract The life cycles of galling insects are synchronized with their host plant phenology, allowing them to better explore available resources.

Optimizing fecal DNA collection and storage techniques for noninvasive genetic sampling of river otters

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.
This study compared 2 non‐invasive DNA collection methods for river otters and found that fecal swabbing consistently outperformed DETs buffer storage across both temperate and tropical environments. Swabbing yielded higher PCR and genotyping success rates while reducing genotyping errors, particularly when sampling anal jelly in tropical conditions ...

Polyphenols, antioxidants, and antimutagenic effects of Copaifera langsdorffii fruit

Food Chemistry, 2016
Copaifera langsdorffii (copaiba) is a Brazilian exotic fruit, poorly studied regarding its bioactive composition. The aim of this study was to determine bioactive compounds, antioxidant and antimutagenic activities of copaiba pulp. The samples were extracted with different solvents in order to analyze polyphenol compounds (Folin Ciocalteau and HPLC-DAD)
