Comparative movement of labelled nitrogen and zinc in 1-year-old peach [Prunus persica (L.) Batsch] trees following late-season foliar application por Sanchez, Enrique Eduardo, Weinbaum, Steven A., Johnson, R. Scott

“…Therefore, future research needs to focus on assessing the efficacy of foliar applications for Zn nutrition of fruit trees, and identification of potentially detrimental effects from possible excessive soil accumulation of Zn. Once within the tree, however, labelled Zn was quite mobile and was stored throughout the plant, including in the roots. …”

Acetic acid lure placement within traps affects moth catches of codling moth (Lepidoptera: Tortricidae) por Barros-Parada, Wilson, Basoalto, Esteban, Fuentes-Contreras, Eduardo, Cichon, Liliana Isabel, Knight, Alan L.

“…Laboratory and field studies found that this negative effect on moth catches lessens over time with aged AA colures that had lower emission rates. The position of the holder in the trap (upwind or downwind) relative to the direction where moths approached was not a significant factor affecting moth catch with the AA colure. …”

Spontaneous Mutations in the Nitrate Reductase Gene napC Drive the Emergence of Eco-friendly Low-N2O-Emitting Alfalfa Rhizobia in Regions with Different Climates por Brambilla, Silvina Maricel, Soto, Gabriela, Odorizzi, Ariel, Arolfo, Valeria, McCormick, Wayne, Primo, Emiliano, Giordano, Walter, Jozefkowicz, Cintia, Ayub, Nicolás Daniel

“…Here, we screened a library of nitrogen-fixing alfalfa symbionts originating from different ecoregions and containing N2O reductase genes and identified novel rhizobia (Sinorhizobium meliloti INTA1–6) exhibiting exceptionally low N2O emissions. To understand the genetic basis of this novel eco-friendly phenotype, we sequenced and analyzed the genomes of these strains, focusing on their denitrification genes, and found mutations only in the nitrate reductase structural gene napC. …”

Citrus tristeza virus infection induces the accumulation of viral small RNAs (21-24-nt) mapping preferentially at the 3'-terminal region of the genomic RNA and affects the host sma... por Ruiz-Ruiz, Susana, Navarro, Beatriz, Gisel, Andreas, Pena, Leandro, Navarro, Luis, Moreno, Pedro, Di Serio, Francesco, Flores, Ricardo

“…Our data show that CTV sRNAs: (i) represent more than 50% of the total sRNAs in Mexican lime and sweet orange (where CTV reaches relatively high titers), but only 3.5% in sour orange (where the CTV titer is significantly lower), (ii) are predominantly of 21-22-nt, with a biased distribution of their 5' nucleotide and with those of (+) polarity accumulating in a moderate excess, and (iii) derive from essentially all the CTV genome (ca. 20 kb), as revealed by its complete reconstruction from viral sRNA contigs, but adopt an asymmetric distribution with a prominent hotspot covering approximately the 3'-terminal 2,500 nt. …”
