Testing of an inexpensive modified atmosphere chamber for small farmers using soaked grain as oxygen scavenger por Bartosik, Ricardo Enrique, Cardoso, Marcelo Leandro, De La Torre, Diego, Abadia, María Bernadette, Tulli, María Celia, Taher, Hernán Ignacio, Maciel, Gisele

“…Results indicated that the respiration rate of soaked grain was 120 to 150 times greater that that of dry wheat. The incorporation of a small quantity of soaked grain as oxygen scavenger (1% dry matter) resulted in a reduction of the oxygen concentration to less than 2%, creating a lethal atmosphere for insects. …”

Trends of aboveground net primary productivity of Patagonian meadows, the omitted ecosystem in desertification studies por Curcio, Matías Hernán, Irisarri, Jorge Gonzalo Nicolás, Garcia Martinez, Guillermo Carlos, Oesterheld, Martin

“…The extended steppes of Patagonia harbor small meadows whose compounded area is comparatively small, but their aboveground net primary production (ANPP) is up to ten times higher than their surroundings. These meadows then represent a key ecosystem for cattle grazing systems, but there are no descriptions of the trends in their ANPP and, consequently, their carrying capacity, and, as a result, their degradation syndromes. …”

Enterohemorrhagic Escherichia coli O157:H7 antigens produced in transgenic lettuce effective as an oral vaccine in mice por Su, Yun‑Lin, Larzabal, Mariano, Song, Huan, Cheng, Tianfang, Wang, Yufang, Smith, Libia Yael, Cataldi, Angel Adrian, Ow, David W.

“…Bovine vaccination has been used to prevent disease outbreaks, and the current method relies on vaccines subcutaneously injected three times per year. Since EHEC O157:H7 colonizes mucosal surfaces, an oral vaccine that produces an IgA response could be more convenient. …”

Discovery of a resistance gene cluster associated with smut resistance in peanut por Chamberlin, Kelly D., Bennett, Rebecca S., Baldessari, Jorge Javier, De La Barrera, Guillermo, Cordes, Guillermo, Grandon, Nancy Gabriela, Mamani, Eva Maria Celia, Rodriguez, Ana Valeria, Morchetti, Sergio, Holbrook, Corley C., Ozias-Akins, Peggy, Ye, Chu, Tallury, Shyam P., Clevenger, Josh, Korani, W., Scheffler, Brian, Youngblood, Ramey Callahan, Simpson, Sheron

“…Each individual was sequenced using iGenomXRipTide library preparation and Illumina NovaSeq sequencing to yield approximately 1 times genome coverage. Analysis of the phenotype and genotype data using Khufu resulted in the identification of a single major smut resistance QTL on chromosome 12 (B02). …”

Soil organic carbon, macro- and micronutrient changes in soil fractions with different lability in response to crop intensification por Romaniuk, Romina Ingrid, Beltran, Marcelo Javier, Brutti, Lucrecia Noemi, Costantini, Alejandro Oscar, Bacigaluppo, Silvina, Sainz Rozas, Hernan Rene, Salvagiotti, Fernando

“…The carbon measured in the coarse particulate fraction (Pcf) in the 0–5 cm soil depth was 3 times larger in S-CC-S than in S-S. Cropping intensity also modified N, S, P, Ca and Mn in the Pcf with no changes in Mg, K, Zn, Fe and Cu contents. …”
