Title A name given to the resource Assessment of Cognitive Changes in Ecological Concepts, in Mexican Junior High School Students Creator An entity primarily responsible for making the resource Sergio Rodolfo Torres Ochoa Description An account of the resource This study was made from a random sample of students of secondary school (basic education), in urban an rural schools of the public sector of the state of Michoacán, Mexico. Significant cognitive changes of basic concepts of Ecology, during the whole academic year were assessed in each one of the three grades which conform this level of education. For such purpose, a group of six fundamental and four complementary concepts was used with which a core concept diagram was elaborated. From this diagram, a 23 task questionnaire was designed and applied as conceptual assessment instrument. The general results show that there are no significant differences, statistically speaking, between the beginning and the end of the academic year, regarding the principal Ecology concepts and other related concepts that were assessed as well. This study included an interpretative phase based in conceptual maps, which results are not included in this article.

Title A name given to the resource Sector Agroalimentario e Integración Regional: una simbiosis necesaria para la Seguridad Alimentaria y Nutricional Creator An entity primarily responsible for making the resource Oscar E. Fernandez-Guillen Description An account of the resource Mediante una investigación documental-descriptiva y cuantitativa-analítica, apoyada en el cálculo e interpretación de indicadores de posición comercial y dinámica del comercio intrarregional, el trabajo examina la relación existente entre agricultura, integración regional y seguridad alimentaria. Para ello analiza el papel desempeñado por la variable agrícola en el contexto de los acuerdos de integración, caracteriza los elementos que confieren sensibilidad al sector agroalimentario y condicionan su tratamiento especial dentro de las experiencias de regionalismo y evalúa el estado de la integración agroalimentaria regional entre 2001 y 2019 comparando tres esquemas latinoamericanos: ALADI, CAN y MERCOSUR. La discusión central argumenta que la profundización del comercio agroalimentario a través de la integración económica ofrece oportunidades para garantizar la seguridad alimentaria, como instrumento capaz de suministrar alimentos de manera estable y fluida, frente a las turbulencias en los mercados internacionales y con costos transaccionales más bajos. Se concluye que en América Latina no existe integración desde el punto de vista del intercambio agroalimentario y se ofrece una serie de recomendaciones a nivel de políticas públicas en aras del desarrollo agrícola, del comercio y del fortalecimiento de la integración.

Title A name given to the resource Cyclodipeptides from Pseudomonas aeruginosa modulate the maize (Zea mays L.) root system and promote S6 ribosomal protein kinase activation Creator An entity primarily responsible for making the resource Iván Corona-Sánchez, Cesar Arturo Peña-Uribe, Omar González-López, Javier Villegas, Jesus Campos-Garcia, Homero Reyes de la Cruz Description An account of the resource Background Pseudomonas aeruginosa is an opportunistic and pathogenic bacterium with the ability to produce cyclodipeptides (CDPs), which belong to a large family of molecules with important biological activities. Excessive amounts of CDPs produced by Pseudomonas strains can activate an auxin response in Arabidopsis thaliana and promote plant growth. Target of rapamycin (TOR) is an evolutionarily conserved eukaryotic protein kinase that coordinates cell growth and metabolic processes in response to environmental and nutritional signals. Target of rapamycin kinase phosphorylates various substrates, of which S6 ribosomal protein kinase (S6K) is particularly well known. The PI3K/Akt/mTOR/S6K signaling pathway has been studied extensively in mammals because of its association with fundamental biological processes including cell differentiation. However, evidences suggest that this pathway also has specific and conserved functions in plants and may thus be conserved, as are several of its components like TOR complex 1 and S6K proteins. In plants, TOR-S6K signaling has been shown to be modulated in response to plant growth promoters or stressors. Methods In this study, we evaluated the effects of P. aeruginosa CDPs on the growth and root development of maize plants (Zea mays L.) by adding different CDPs concentrations on culture plant media, as well as the effect on the phosphorylation of the maize S6K protein (ZmS6K) by protein electrophoresis and western blot. Results Our results showed that P. aeruginosa CDPs promoted maize growth and development, including modifications in the root system architecture, correlating with the increased ZmS6K phosphorylation and changes induced in electrophoretic mobility, suggesting post-translational modifications on ZmS6K. These findings suggest that the plant growth-promoting effect of the Pseudomonas genus, associated with the CDPs production, involves the TOR/S6K signaling pathway as a mechanism of plant growth and root development in plant–microorganism interaction.

Title A name given to the resource Potential of Lactic Acid Bacteria Isolated From Different Forages as Silage Inoculants for Improving Fermentation Quality and Aerobic Stability Creator An entity primarily responsible for making the resource Melisa Puntillo, Mónica Gaggiotti, Juan Martín Oteiza, Ana Binetti, Ariel Massera, Gabriel Vinderola Description An account of the resource We aimed at isolating lactic acid bacteria (LAB) from different plant materials to study their crossed-fermentation capacity in silos and to find strains able to confer enhanced aerobic stability to silage. A total of 129 LAB isolates were obtained from lucerne (alfalfa), maize, sorghum, ryegrass, rice, barley, canola, Gatton panic, Melilotus albus, soy, white clover, wheat, sunflower, oat, and moha. Four Lactiplantibacillus plantarum subsp. plantarum strains (isolated from oat, lucerne, sorghum, or maize) were selected for their growth capacity. Identity (16S sequencing) and diversity (RAPD-PCR) were confirmed. Fermentative capacity (inoculated at 104, 105, 106, 107 CFU/g) was studied in maize silage and their cross-fermentation capacity was assessed in oat, lucerne, sorghum, and maize. Heterofermentative strains with the highest acetic acid production capacity conferred higher aerobic stability to maize silages. Regardless the source of isolation, L. plantarum strains, inoculated at a rate of 106 CFU/g, were effective to produce silage from different plant materials. From more than 100 isolates obtained, the application of a succession of experiments allowed us to narrow down the number of potential candidates of silage inoculants to two strains. Based on the studies made, L. plantarum LpM15 and Limosilactobacillus fermentum LfM1 showed potential to be used as inoculants, however further studies are needed to determine their performance when inoculated together. The former because it positively influenced different quality parameters in oat, lucerne, sorghum, and maize silage, and the latter because of its capacity to confer enhanced aerobic stability to maize silage. The rest of the strains constitute a valuable collection of autochthonous strains that will be further studied in the future for new applications in animal or human foods.

Title A name given to the resource The Banana Root Endophytome: Differences between Mother Plants and Suckers and Evaluation of Selected Bacteria to Control <i>Fusarium oxysporum</i> f.sp. <i>cubense</i> Creator An entity primarily responsible for making the resource Carmen Gómez-Lama Cabanás, Antonio J. Fernández-González, Martina Cardoni, Antonio Valverde-Corredor, Javier López-Cepero, Manuel Fernández-López, Jesús Mercado-Blanco Description An account of the resource This study aimed to disentangle the structure, composition, and co-occurrence relationships of the banana (cv. Dwarf Cavendish) root endophytome comparing two phenological plant stages: mother plants and suckers. Moreover, a collection of culturable root endophytes (>1000) was also generated from Canary Islands. In vitro antagonism assays against Fusarium oxysporum f.sp. cubense (Foc) races STR4 and TR4 enabled the identification and characterization of potential biocontrol agents (BCA). Eventually, three of them were selected and evaluated against Fusarium wilt of banana (FWB) together with the well-known BCA Pseudomonas simiae PICF7 under controlled conditions. Culturable and non-culturable (high-throughput sequencing) approaches provided concordant information and showed low microbial diversity within the banana root endosphere. Pseudomonas appeared as the dominant genus and seemed to play an important role in the banana root endophytic microbiome according to co-occurrence networks. Fungal communities were dominated by the genera Ophioceras, Cyphellophora, Plecosphaerella, and Fusarium. Overall, significant differences were found between mother plants and suckers, suggesting that the phenological stage determines the recruitment and organization of the endophytic microbiome. While selected native banana endophytes showed clear antagonism against Foc strains, their biocontrol performance against FWB did not improve the outcome observed for a non-indigenous reference BCA (strain PICF7).

Title A name given to the resource Assessment of Genetic Diversity and Structure of Large Garlic (Allium sativum) Germplasm Bank, by Diversity Arrays Technology “Genotyping-by-Sequencing” Platform (DArTseq) Creator An entity primarily responsible for making the resource Leticia A. Egea, Leticia A. Egea, Rosa Mérida-García, Andrzej Kilian, Pilar Hernandez, Gabriel Dorado Description An account of the resource Garlic (Allium sativum) is used worldwide in cooking and industry, including pharmacology/medicine and cosmetics, for its interesting properties. Identifying redundancies in germplasm blanks to generate core collections is a major concern, mostly in large stocks, in order to reduce space and maintenance costs. Yet, similar appearance and phenotypic plasticity of garlic varieties hinder their morphological classification. Molecular studies are challenging, due to the large and expected complex genome of this species, with asexual reproduction. Classical molecular markers, like isozymes, RAPD, SSR, or AFLP, are not convenient to generate germplasm core-collections for this species. The recent emergence of high-throughput genotyping-by-sequencing (GBS) approaches, like DArTseq, allow to overcome such limitations to characterize and protect genetic diversity. Therefore, such technology was used in this work to: (i) assess genetic diversity and structure of a large garlic-germplasm bank (417 accessions); (ii) create a core collection; (iii) relate genotype to agronomical features; and (iv) describe a cost-effective method to manage genetic diversity in garlic-germplasm banks. Hierarchical-cluster analysis, principal-coordinates analysis and STRUCTURE showed general consistency, generating three main garlic-groups, mostly determined by variety and geographical origin. In addition, high-resolution genotyping identified 286 unique and 131 redundant accessions, used to select a reduced size germplasm-bank core collection. This demonstrates that DArTseq is a cost-effective method to analyze species with large and expected complex genomes, like garlic. To the best of our knowledge, this is the first report of high-throughput genotyping of a large garlic germplasm. This is particularly interesting for garlic adaptation and improvement, to fight biotic and abiotic stresses, in the current context of climate change and global warming.

Gmel y U. tomentosa (Willd. ex Roemer & Schultes) DC.), empleada en la medicina tradicional amazónica, se destaca por tener propriedades farmacológicas que han generado un interés comercial. Hasta el momento hay una mayor cantidad de estudios sobre el manejo agroforestal y los métodos de propagación de la U. tomentosa; no obstante, es poca la información disponible sobre la Uncaria guianensis, en especial con lo relacionado a su manejo en comunidades. Con el propósito de contribuir con información sobre el manejo de estas especies y de evaluar su propagación vegetativa, se realizaron entrevistas, recorridos de campo y ensayos de siembra en comunidades Tikuna. Se encontró que el manejo de las especies de uña-de-gato, principalmente de la Uncaria guianensis, se centra tanto en las prácticas de extracción y siembra por estacas, así como en su regeneración natural. Igualmente, en los experimentos de propagación vegetativa se evidenció que la Uncaria tomentosa presentó una alta tasa de mortalidad, pues fue más susceptible a los efectos de las condiciones ambientales. Por el contrario, la Uncaria guianensis tuvo una mayor tasa de sobrevivencia, especialmente en bosques secundarios donde se sembraron estacas tratadas con hormonas de enraizameinto y en suelos enriquecidos con abono orgánico. Los resultados obtenidos en este estudio pueden contribuir en la formulación de estrategias de manejo integral, que permitan un uso sostenible de poblaciones naturales de las especies de uña-de-gato en comunidades amazónicas.

A. Camargo, I. C. de Maria, M. V. Galdos Description An account of the resource A utilização de lodo de esgoto como fertilizante orgânico ou condicionador do solo, tem-se tornado cada vez mais atraente, pelos altos custos e impactos ambientais relacionados com os demais métodos de disposição, pela presença de nutrientes vegetais e matéria orgânica no lodo e pela necessidade de redução de custos na agricultura. No entanto, em sua composição, pode conter metais pesados, microrganismos patogênicos e compostos orgânicos tóxicos. Visando estudar os efeitos da aplicação de lodo de esgoto em áreas agrícolas, foi realizado um experimento, com duração de dois anos agrícolas, para determinar alterações em propriedades químicas do solo, principalmente sobre os teores de P, Cu, Ni e Zn em um Latossolo Vermelho eutroférrico, de textura argilosa, cultivado com milho. O experimento consistiu na aplicação de lodo de esgoto em duas doses comparadas a uma testemunha com adubação química. Para análise de rotina das propriedades químicas e do teor de Ni do solo, foram coletadas amostras nas profundidades de 0-0,05; 0,05-0,10 e 0,10-0,20 m após a colheita do milho no primeiro e no segundo ano. Foi feita, também, uma extração seqüencial de P em amostras da camada de 0-0,05 m, na seguinte ordem: CaCl2 (P biologicamente mais disponível); NaHCO3 (P disponível); NaOH (P ligado aos óxidos de Fe e Al); HCl (P ligado a Ca) e digestão nítrico-perclórica (P residual). A produção do milho foi maior nos tratamentos com aplicação do lodo. Os teores disponíveis de P no solo onde foi aplicado lodo foram semelhantes aos do tratamento sem lodo e com adubo químico. Entretanto, a aplicação do lodo aumentou as frações lábeis e moderadamente lábeis do P na camada superficial. Os dados indicaram, por outro lado, aumento dos teores de Cu, Ni e Zn no solo e de Zn na planta. Dessa forma, faz-se necessário constante monitoramento do solo onde o lodo de esgoto é aplicado para o controle adequado dos teores de metais.The application of sewage sludge into agricultural soils, as organic fertilizer or soil conditioner, is becoming an increasingly more attractive alternative. It is occurring because of the high costs and environmental impacts caused by other sludge disposal methods, besides the presence of plant nutrients and organic matter in the sludge and the need to reduce costs in agriculture. However, sewage sludge can contain heavy metals, pathogenic microorganisms, and toxic organic compounds. In order to study the impact of sewage sludge application in agricultural areas, a two-year experiment was implemented to determine the changes in soil chemical properties, mainly in the P, Cu, Ni and Zn contents, in an eutroferric clayey Red Latosol (Rhodic Eutrustox) cropped with corn. The experiment consisted of two application rates of sewage sludge and a control with chemical fertilization. Soil samples were collected at the 0-0.05; 0.05-0.10, and 0.10-0.20 m depths after the corn harvest in both years for a routine chemical analysis and the Ni content. Additionally, a sequential P extraction for samples of the 0 to 0.05 m layer was carried out in the following order: CaCl2 (P biologically most available); NaHCO3 (available P); NaOH (P adsorbed to the Fe and Al oxides); HCl (P adsorbed to Ca) and nitric-perchloric digestion (residual P ). Corn yield was higher in the treatments with sludge application. The available P content in soils that received sludge application was similar to those of the treatment without sludge and with chemical fertilizer. However, sludge application increased the labile and moderately labile P fractions in the surface soil layer. The data suggested, however, increased Cu, Ni, and Zn concentration in soil and Zn concentration in plants. Thus, a constant monitoring of soils that receive application of sewage sludge is required for an adequate control of the metal levels.
