mRNA biogenesis-related helicase eIF4AIII from Arabidopsis thaliana is an important factor for abiotic stress adaptation por Pascuan, Cecilia Gabriela, Frare, Romina Alejandra, Alleva, Karina Edith, Ayub, Nicolás Daniel, Soto, Gabriela Cinthia

“…In this article, we integrated evolutionary and functional approaches to have a better understanding of eIF4AIII function in plants. Phylogenetic analysis showed that the mRNA biogenesisrelated helicase eIF4AIII is the ortholog of the stress-related helicases PDH45 from Pisum sativum and MH1 from Medicago sativa, suggesting evolutionary and probably functional equivalences between mRNA biogenesis and stress-related plant helicases. …”

Detection and molecular characterization of a phytoplasma affecting Prunus persica L. in Jujuy, Argentina por Fernandez, Franco Daniel, Guzman, Fabiana, Curzel, Viviana, Bejarano, Noemí, Conci, Luis Rogelio

“…The RFLP profile of PCR products, amplified with R16F2n/R16R2 primers, shows that this phytoplasma, named Argentinean Peach Yellows (ArPY), belongs to subgroup 16Sr III-B. The phylogenetic analysis of the 1244 bp 16S rDNA cloned sequence, grouped the ArPY phytoplasma into the X-disease group with a closer relationship with CFSD, PssWB and ChTDIII phytoplasmas. …”

Molecular characterisation of rice stripe necrosis virus as a new species of the genus benyvirus por Lozano Potes, Iván, Morales, Francisco José

“…RNAs 3 and 4 (or 5 in the case of BNYVV), identified in natural infections of BNYVV and BSBMV, were not detected in any of the 44 RSNV cDNA clones obtained in this investigation.
