Silencing Gene with dsRNA of Different Lengths Impairs Larval Development in .

In the search for effective strategies to control the Colorado Potato Beetle, RNA interference technology has emerged as a promising method due to its capacity to suppress genes selectively. Factors such as the target gene and double-stranded RNA (dsRNA) length are critical for optimizing gene silencing efficiency. In this study, we designed and synthesized in vitro dsRNAs of varying lengths targeting the gene, which encodes the AChE1 isoform of acetylcholinesterase in the beetle.

Article biodiversity inside bottles: animals, fungi, and plants in traditional alcoholic drinks.

The use of animals, fungi, and plants as a source of bioactive compounds has been widely practiced in diverse cultures throughout the world, particularly in alcoholic drinks. The nature of the biological material, method of preparation and alcohol concentration play a predominant role in the extraction of bioactive compounds and the achievement of desired results. However, certain aspects must be considered to guarantee the innocuity of these drinks and reduce the risk of intoxication, infections and allergic reactions, aspects which are sometimes overlooked.

Piquin chili, a wild spice: natural variation in nutraceutical contents.

The piquin chili is a wild spice widely consumed from the South United States to Central America and stands out as a source of flavonoids, essential metabolites with antioxidant properties. The concentrations of flavonoids, carotenoids, and capsaicinoids vary according to regions, maturity stages, and ripening processes. These compounds, which are known for their health benefits and industrial applications, highlight the importance of identifying ideal environmental conditions for collecting fruits with the highest contents.

evaluation of the antagonistic activity of native strains of spp. against spp.

Five samples of agricultural soil and five samples of (P. Mill., 1768) plants with symptoms of wilt and root necrosis were collected in five localities of the state of Tamaulipas, México.

biocontrol of with antagonistic microorganisms and effect on L.

The objective was to evaluate the effects of biocontrol of spp. and spp. against and its effect on plants.

Evaluation of Resistance of Eleven Maize Races ( L.) to the Red Spider Mite (, Boudreaux).

At least 59 maize races ( L.) have been registered in Mexico. The feeding damage caused by insects and mites to maize crops generates up to ~30% of maize yield losses.

Schistocerca piceifrons piceifrons (Orthoptera: Acrididae) as a Source of Compounds of Biotechnological and Nutritional Interest.

The Central American locust, Schistocerca piceifrons piceifrons (Walker) is a major agricultural pest in Mexico and Central America. Control measures against this pest have generated much environmental damage and substantial financial costs because chemical insecticides are used. Yet various Orthoptera species also appear to be a potential source of nutrients and a source of bioactive metabolites.

Variability in the Phytochemical Contents and Free Radical-Scavenging Capacity of Capsicum annuum var. glabriusculum (Wild Piquin Chili).

The variability in the phytochemical concentrations of Capsicum annuum var. glabriusculum has not been extensively analyzed among wild populations and ecologic niches in its phylogeographic area. This study aimed to determine the variations in the phytochemical and antioxidant contents of the wild Piquin chili.

Drying Effects on Phenolics and Free Radical-Scavenging Capacity of and Used in Traditional Medicine.

and are medicinal plant species with important uses in northeastern Mexico. They belong to a complex of species called "lantriscos", which are used for medicinal applications. The medicinal effects of these species are based on traditional use, however, they require phytochemical research to validate their medicinal properties, as well as structural characterization for their correct identification during the collecting practice and uses.

Free Radical-Scavenging Capacities, Phenolics and Capsaicinoids in Wild Piquin Chili ( var. ).

The total phenolic compounds content, free radical-scavenging capacity and capsaicinoid content in populations of wild Piquin chili () were studied. Aqueous and hydroalcoholic extracts from nine ecotypes were evaluated. High contents of phenolic compounds and free radical-scavenging capacities were observed for both extracts; however, the values that were found for the hydroalcoholic phase were substantially higher.

Biofunctional properties of bioactive peptide fractions from protein isolates of moringa seed ().

(Moringaceae) is a specie of significant importance because of its multiple nutraceutical properties, that has led to increase in its consumption. The seeds contain a high percentage of protein (37.48%).

Natural variability of essential oil and antioxidants in the medicinal plant Turnera diffusa.

Objective: To evaluate differences in yield and composition of the essential oil and antioxidant contents in Turnera diffusa plants from localities in central region of Tamaulipas.

Methods: Samples were collected in Tamaulipas, Mexico in the arid zone. Essential oil was obtained through steam distillation and analyzed using GC-MS.
