Evidence of nitro-fatty acids in microscopic algae and cyanobacteria

Nitro-fatty acids (NO 2 FAs) are pleiotropic cell signalling modulators, playing a role in stress responses, development, and defence mechanisms in many organisms, including plants. However, to date their production in photosynthetic microorganism has not been studied. In this st...

Preferential antiproliferative activity of an oleandrigenin-derived androstane toward prostate cancer cells

Abstract Cardiac glycosides, traditionally used for heart failure, are increasingly recognized for their anticancer potential. This study evaluated the in vitro antitumor activity of ten cardiac glycoside derivatives on androgen-insensitive (DU-145) and androgen-sensitive (LNCaP)...

Introducing relative pollen productivity estimates for Iberian taxa: methodological insights and implications for landscape modelling in the Western Mediterranean

Abstract. Understanding the impact of ongoing global change on plant communities requires long-term quantitative reconstructions of past vegetation dynamics. Fossil pollen records offer one of the most powerful tools to reconstruct past landscapes, yet for their accurate interpre...

Anti-methicillin-resistant Staphylococcus aureus (Anti-MRSA) flavonoids from Iraqi Citrus sinensis (L.) Osbeck

Citrus sinensis (L.) Osbeck (Rutaceae) was investigated as a potential source of anti-MRSA compounds. A bioassay-guided isolation approach afforded fourteen compounds from the peel and leaf extracts of C. sinensis , including a new flavanone glycoside, sinensidin ( 10 ). Structur...

Ajuga reptans L. from Romanian flora as a promising candidate for novel food applications

The increasing demand for natural ingredients with both functional and sensory properties has stimulated the exploration of underutilised plant species as potential sources for novel food applications. Ajuga reptans L. (Lamiaceae) remains relatively underexplored despite its phyt...

Unveiling centromeric retrotransposon dynamics through a high-quality rye genome assembly

Abstract Rye ( Secale cereale L.) is an important cereal crop known for its high yield potential and tolerance to biotic and abiotic stresses. However, its large, repeat-rich, and heterozygous genome has posed challenges for assembly compared to related species such as wheat and...

Single‐Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum

B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue-specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome mai...
