In studies on the reproduction and germination of species with indehiscent fruits containing a single seed, it is often assumed that all fruits that reach maturity contain a seed capable of generating a new plant. This i...

Abstract Seed selection constitutes the initial and one of the most critical steps in agricultural productivity. The identification of high-quality seeds is a labor-intensive and costly process that requires considerable...

Abstract A field study of the floral biology of Victoria amazonica (Poepp.) Sowerby (Nymphaeaceae) was made for comparison with the many studies made in cultivated plants, of Victoria in the past. In the study areas in t...

Abstract Background Pinus yunnanensis, an evergreen coniferous species native to southwestern China, possesses considerable ecological and economic importance. In this study, two-year-old P. yunnanensis seedlings were ca...

Whilst common across the animal kingdom, the evolution of cannibalism remains poorly understood. Part of the problem is that the number of taxonomic groups in which the evolution of cannibalism has been studied in detail...

Flower morphology, nectary structure, nectar chemical composition, breeding system, floral visitors and pollination were analysed in Croton sarcopetalus, a diclinous-monoecious shrub from Argentina. Male flowers have fiv...

Abstract Background Optimizing the seeding rate is critical for wheat productivity. However, excessive densification often compromises individual photosynthetic efficiency to maximize canopy light interception, creating ...

Nyamplung (Calophyllum inophyllum L.) is reported to have ethnomedicinal benefits in traditional medicine systems. Leaves, fruit, seeds, flowers, stems, roots and essential oils are the parts that are often used. Previou...

Microbial siderophores are low-molecular-weight compounds with a strong affinity for ferric (FSe3+) ions. They play a pivotal role in plant-microbial interactions by enhancing iron bioavailability to plants, primarily th...

Background and aims – While some plants achieve reproductive success through wind or deceptive pollination strategies, many animal-pollinated species depend on mutualistic interactions with pollinators, supported by fl...

El presente trabajo analiza aspectos de alimentación en medio natural de la tortuga, Peltocephalus dumerilianus (Testudines: Podocnemididae; cabezón), a partir de muestras de contenidos alimenticios tomados de estómag...

This work describes a new method for extracting genomic DNA from heavy oil-contaminated soils. This method combines soil washes using three washing solutions with enzymatic lysis (SW-EL method). The suitability of the SW...

Abstract This study investigates the unconventional effects of gamma irradiation and/or metal-organic frameworks (MOFs) on Raphanus sativus. Silver chromate/aluminum-based MOFs were applied to both irradiated and non-irr...

Abstract Background Endometriosis is a highly prevalent, hormone-driven chronic disease characterized by the growth of endometrial tissue outside the uterine cavity. Despite its impact, the mechanisms underlying the dise...

Abstract Background Fusarium crown rot (FCR) caused by species of Fusarium fungus is a global soil-borne disease of wheat. Increasing results indicate frequent controversy between seedling and adult plant resistance to F...

This study aims to examine the role of exosomes derived from human urine-derived stem cells (hUSCs-Exo) in the in vitro construction of a composite structure comprising hUSCs and a porcine urethral decellularized matrix...
