Phenotyping sunflower genetic resources for Sclerotinia head rot response: assessing variability for disease resistance breeding
(The American Phytopathological Society, 2017-11)Sclerotinia head rot (SHR) is one of the most serious constraints to sunflower (Helianthus annuus L. var. macrocarpus) production worldwide. Here, we evaluated the response to SHR in a sunflower inbred panel from a large ... -
Phosphatidylinositol 3-kinase function at very early symbiont perception: a local nodulation control under stress conditions?
(Society for Experimental Biology, 2018-04)Root hair curling is an early and essential morphological change required for the success of the symbiotic interaction between legumes and rhizobia. At this stage rhizobia grow as an infection thread within root hairs and ... -
Phylodynamic analysis of foot-and-mouth disease virus evolution in Mar Chiquita, Argentina
(Springer, 2024-05)Foot-and-mouth disease is a highly contagious disease affecting cloven-hoofed animals, resulting in considerable economic losses. Its causal agent is foot-and-mouth disease virus (FMDV), a picornavirus. Due to its error-prone ... -
Phylodynamics of sunflower chlorotic mottle virus, an emerging pathosystem
(Elsevier, 2020-03-12)Distribution and epidemiological patterns of sunflower chlorotic mottle virus (SCMoV) in sunflower (Helianthus annuus L.) growing areas in Argentina were studied from 2006 to 2017. The virus was detected exclusively in ... -
Phylogenetic analysis of ORF viruses from five contagious ecthyma outbreaks in Argentinian goats
(2018-06)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 ... -
Phylogenetic and structural analyses of equine rotaviruses : three possible geographically related lineages
(2016)The structural analyses revealed that the aa substitutions in VP7 are in the antigenic sites and in the VP7:VP6 interaction region. In accordance, most of the aa changes in VP6 are in the top of the protein involving ... -
Phylogenetic relationships of Argentinean Creole with other Latin American Creole Cattle as revealed by a medium density SNP microarray
(Asociación Latinoamericana de Producción Animal, 2021)The demographic history of the Criollo cattle in Argentina and in Latin America in general dates back to the time of Spanish colonization. The objective of this study was to investigate the potential use of a medium-density ... -
Phylogenetic relationships of Petunia patagonica (Solanaceae) revealed by molecular and biogeographical evidence
(2015)Petunia patagonica is restricted to the Patagonian region of Argentina and its identity is controversial. The species was described in the genus Nierembergia, and subsequently transferred to the genus Petunia. However, ... -
Phylogeny of digitaria sections Trichachne and Trichophorae (Poaceae, Panicoideae, Paniceae) : a morphological and molecular analysis. New circumscription and synopsis
(2017)The present study provides evidence for taxonomic delimitation of Digitaria sect. Trichachne based on morphological data (micro- and macromorphology) and molecular data. A phylogenetic analysis was performed using 121 ... -
Phylogeographic analysis of the 2000-2002 foot-and-mouth disease epidemic in Argentina
(2016)Foot-and-mouth disease (FMD) is a highly transmissible disease of hooved livestock. Although FMD has been eradicated from many countries, economic and social consequences of FMD reintroductions are devastating. After ... -
Physical and chemical variables analysis for clustering of soils in the longitudinal dunes of Sandy Pampa, Argentina
(Springer, 2016-08)The Sandy Pampa landscape was built on ancient dune-shaped landforms, which persist today and affect the characteristics of the soil in different sectors of the dunes. Based on their topographic position, different soils ... -
Physico-chemical composition and oxidative stability of South African beef, game, ostrich and pork droëwors

Physiological and anatomical traits associated with tolerance to long‐term partial submergence stress in the Lotus genus: responses of forage species, a model and an interspecific hybrid
(2018-09)Cattle production based on natural pastures is often subject to flooding periods, which affect plant performance and as a result, forage production. Although most forage legumes are not tolerant to flooding, Lotus spp. are ... -
Physiological and genetic characterization of wheat lines sharply differing in sodium accumulation
