Molecular identification and pathogenicity of Rhizoctonia spp. from tobacco growing areas in northwestern Argentina por Mercado Cardenas, Guadalupe Eugenia, Galvan, Marta Zulema, Barrera, Viviana Andrea, Rodriguero, Marcela Silvina, Carmona, Marcelo Anibal, March, Guillermo Juan, Ramallo, Ana Carolina, Shew, H. David

“…In Argentina, more than 60 % of the tobacco crops are grown in the northwestern part of the country and where Rhizoctonia solani leads to a reduction in crop yield and quality. In this study, 35 isolates of Rhizoctonia were obtained from 32 tobacco fields in northwestern Argentina and characterized by both morphological and molecular approaches. …”

Phylogenetic analysis of ORF viruses from five contagious ecthyma outbreaks in Argentinian goats por Peralta, Andrea Veronica, Robles, Carlos Alejandro, Micheloud, Juan Francisco, Rossanigo, Carlos Esteban, Martinez, Agustin, Carosio, Agustin, Konig, Guido Alberto

“…Orf virus (ORFV) is the etiological agent of Contagious Ecthyma (CE) disease that mainly affects sheep, goats, wild ruminants, and humans with a worldwide distribution. To date, only two strains from Argentinian sheep have been characterized at the molecular level and there is little information on ORFV strains circulating in Argentina. …”

Redox-related metabolites and gene expression modulated by sugar in sunflower leaves: similarities with Sunflower chlorotic mottle virus-induced symptom por Rodriguez, Marianela, Muñoz, Nacira Belen, Lenardon, Sergio Luis, Lascano, Hernan Ramiro

“…The expression of the genes analyzed was also strongly affected by sugar, such as the down-regulation of psbA and up-regulation of psbO and cp29. The expression level of cytoplasmic (apx-1 and gr)- and chloroplastic (Fe-sod)-targeted genes was also significantly enhanced in sugar-treated leaves. …”

Effects of organic amendment application on soil quality and garlic yield in central-western Argentina por Filippini, Maria Flavia, Abril, Adriana, Cony, Mariano Anibal, Noe, Laura, Venier, Matias, Cónsoli, Daniela, Vallone, Rosana Celia

“…Also we evaluate garlic yield and possible health risks as resulting from the organic amendments and the wastewater use. We found that: a) different doses and types of amendments did not have any significant effects on soil fertility; b) chicken manure and soil before planting, had E. coli and Salmonella spp.; and c) crop yields were quite similar in all treatments, only treatments with 8 Mg ha-1 of both amendments (chicken manure and vermicompost) without N fertilized, were significantly higher than control in both garlic assays. …”

Influence of cultivar and cutting date on the fatty acid composition of forage crops for grazing beef production in Argentina por Garcia, Pilar Teresa, Pordomingo, Anibal, Perez, Carolina Daiana, Ríos, M.D., Sancho, Ana Maria, Volpi Lagreca, Gabriela, Casal, Jorge José

“…Data variation in both total lipids and individual fatty acid proportions in forages should be taken into account to establish the potential to cultivate crops for a higher content of n-3 PUFA and hence the opportunity to deliver more n-3 PUFA and CLA into beef.…”

The phylogenetic structure of plant–pollinator networks increases with habitat size and isolation por Aizen, Marcelo Adrian, Gleiser, Gabriela Laura, Sabatino, Cristina Malena, Gilarranz, Luis J., Bascompte, Jordi, Verdú del Campo, Miguel

“…We propose that habitat fragmentation would erode the phylogenetic structure of interaction webs. A decrease in phylogenetic signal and co‐phylogenetic correspondence in plant–pollinator interactions could be associated with less reliable mutualism and erratic co‐evolutionary change.…”
