Variantes génicas asociadas con caracteres reproductivos y su utilización en el esquema de selección de ovejas de Rasa Aragonesa
No full textLa utilización de marcadores genéticos en los programas de mejora genética hace que sean más eficientes y, sobre todo, para aquellos caracteres que presentan una baja heredabilidad y una difícil y costosa medida, como son en general los caracteres reproductivos. Por otra parte, hay que tener en cuenta, que habría que validar sus efectos en poblaciones comerciales que usan tratamientos hormonales o un manejo diferente, que podrían producir interacciones y por lo tanto modificar los resultados de los genes analizados.A UPRA Grupo Pastores (Unión de Productores Grupo Raza Rasa Aragonesa) y ganaderos de Rasa Aragonesa por su implicación y participación activa en diferentes proyectos que han dado lugar al aislamiento de variantes genéticas asociadas a carácter reproductivos.

Apple peels as an edible source of phenolic bioactive compounds with antidiabetic and antiglycation properties
Full text linkApples (Malus domestica Borkh.) are one of the most consumed fruits around the world with a high production of peels as wastes and by-products. In this work, peels from different commercial and local apple samples are explored as a source of phenolic bioactive compounds that could be directly related to the prevention of type 2 diabetes. Six different cultivars from local and commercial apple samples were processed to obtain the phenolic compounds by ultrasonication of the peels using methanol as the solvent. The phenolic content was explored using the Folin–Ciocalteu assay and the quantification of 37 individual phenolic compounds was carried out by high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS/MS). Cellular viability was determined by performing the MTT assay in Caco-2 cell cultures exposed to the phenolic extracts. Subsequently, the capacity to inhibit ?-glucosidase, ?-amylase and pancreatic lipase enzymes, as well as antiglycation and antioxidant activities, was evaluated. These apple peel samples were considered a source of phenolic compounds with hyperoside, delphinidin 3,5-diglucoside, chlorogenic acid, phlorizin, epicatechin and procyanidin B2 as the main constituents. All samples neutralized the production of advanced glycation end-products and exhibited antiradical activities in a dose-dependent manner; four samples (Amarilla de Octubre, Manzana Helada, Verde Doncella and Pinova) inhibited ?-glucosidase but only the sample known as “Amarilla de Octubre” was successful in inhibiting pancreatic ?-amylase. Cytotoxicity was discarded in Caco-2 cell cultures at physiological concentrations considering these extracts as a source of phenolic compounds with antidiabetic, antiglycation and antioxidant properties.This work is part of the APPLEDIV Project (Multidisciplinary

Weed Control in Perennial Crops Using Hydromulch Compositions Based On the Circular Economy: Field Trial Results
Full text linkWeed control in perennial crops is especially difficult in the first phases of crop establishment. Hydromulch is a pasty blend that hardens after application and has so far been used specifically for weed control for experimental purposes only. In this work we tested blends based on recycled paper, gypsum and lignocellulosic materials (wheat straw, rice husk and used mushroom substrate) applied in three different locations of Spain under peach, vine, almond and artichoke plantations compared with an untreated control, manual weeding and herbicide (only in artichoke). The most frequent weed species were annual and perennial forbs. Lower weed soil cover compared to the untreated control was still relevant between 333 and 456 days after mulching (DAM), depending on the trial. In the artichoke trial the weed control effect was similar to that obtained with herbicides until the end of the assessments. Annual forbs were satisfactorily controlled with hydromulches (highest for Lamium amplexicaule with an efficacy of 88% based on soil cover); mean efficacy of perennials such as Cyperus rotundus and Convolvulus arvensis was lower ranging between 30 and 74% efficacy depending on the trial. Multivariate analysis showed an increase in wind-dispersed species such as Conyza sp. and Lactuca serriola over time. The capacity of the mulches to reduce weed soil cover for around one year can be useful in crops where weed control is crucial during that time, such as in plant nurseries and new plantations. Future research could focus improving the durability of the mulches to extend this period.This research was funded by the Ministerio de Economía y Competitividad [INIA RTA2015-00047 and PID2020-113865RR-C41].mulchingbiodegradable materialsphysical weed controlCyperus rotudusConvolvulus arvensisConyza sp.Publishe
Mass Spectrometry-Based Non-Targeted Lipidome Analysis and Extraction of Markers for the Authentication of White and Black Truffle Species and Their Origin Determination
Full text linkThe visual authentication of high-value truffles (Tuber magnatum and Tuber melanosporum) is challenging, as they share similar morphological characteristics with other truffle species that have a lower economic value. This similarity complicates accurate identification and increases the risk of substitution or mislabeling, which can affect both market prices and consumer trust. For this reason, the aim of this study was to apply a non-targeted lipidomic approach using ion mobility spectrometry-mass spectrometry to distinguish between white (T. magnatum, Tuber borchii, and Tuber oligospermum) and black truffle species (T. melanosprum, T. aestivum, T. aestivum var. uncinatum, T. brumale, and T. indicum) and to determine the different geographical origins of the two most valuable truffle species (T. melanosporum and T. magnatum). Among several hundred features, 37 and 57 lipids were identified as marker compounds to distinguish white and black truffle species using MS/MS spectra and collision cross section (CCS) values, respectively. Only a few marker compounds were necessary to recognize the differences between white and black truffles. In particular, ceramides, glycerolipids, and phospholipids proved to be particularly suitable for separating the species. In addition, different metabolite profiles were determined for T. melanosporum and T. magnatum depending on their geographical origin. These findings lay the groundwork for a comprehensive quality control framework for fresh truffles, ensuring authenticity, detecting adulteration, and preserving their premium status.This research was supported by Diputación Provincial de Zaragoza (DPZ) in
