A South American Mouse Morbillivirus Provides Insight into a Clade of Rodent-Borne Morbilliviruses by Debat, Humberto Julio

“…Structural and functional annotation, genetic distance, and evolutionary insights suggest that RoMV is a member of a novel species within genus Morbillivirus tentatively named as South American mouse morbillivirus. Phylogenetic analysis suggests that this mouse morbillivirus is closely related to and clusters into a monophyletic group of novel rodent-borne morbilliviruses. …”

Genome-Wide Analyses of Aspartic Proteases on Potato Genome (Solanum tuberosum): Generating New Tools to Improve the Resistance of Plants to Abiotic Stress by Norero, Natalia Sigrid, Rey Burusco, María Florencia, D’Ippólito, Sebastián, Decima Oneto, Cecilia Andrea, Massa, Gabriela Alejandra, Castellote, Martín Alfredo, Feingold, Sergio Enrique, Guevara, María Gabriela

“…A high number of intronless genes and segmental and tandem duplications were detected. Phylogenetic analysis revealed eight StAP groups, named from StAPI to StAPVIII, that were differentiated into typical (StAPI), nucellin-like (StAPIIIa), and atypical aspartic proteases (StAPII, StAPIIIb to StAPVIII). …”

Detection and identification of a novel 16SrXIII subgroup phytoplasma associated with strawberry red leaf disease in Argentina by Fernandez, Franco Daniel, Meneguzzi, Natalia, Guzman, Fabiana, Kirschbaum, Daniel Santiago, Conci, Vilma Cecilia, Nome Docampo, Claudia, Conci, Luis Rogelio

“…In silico the RFLP profile of all the samples analysed revealed the presence of a unique pattern, showing that the novel phytoplasma is different from all the phytoplasmas currently composing the 16SrXIII group. The phylogenetic analysis was consistent with RFLP analysis as the strawberry red leaf phytoplasma was grouped within the 16SrXIII group, but formed a particular cluster. …”

Ecological and physiological thermal niches to understand distribution of Chagas disease vectors in Latin America by De La Vega, Gerardo, Schilman, Pablo Ernesto

“…Then, thermal tolerance limits were analysed by measuring maximum and minimum critical temperatures, upper lethal temperature, and ‘chill-coma recovery time’. Finally, we used phylogenetic independent contrasts to analyse the link between limiting factors and the thermal tolerance range for the assessment of ecological hypotheses that provide a different outlook for the geo-epidemiology of Chagas disease. …”
