(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020)Sharka, caused by Plum pox virus (PPV), is considered one of the most serious viral diseases of stone fruits worldwide due to the great yield losses in orchards. In Rama Caída, Mendoza, a 5-year study (2007-2011) was ... -
Species diversity of Cladorrhinum in Argentina and description of a new species, Cladorrhinum australe
(Springer, 2015-10)The genus Cladorrhinum constitutes a fungal group of prime importance for agriculture and livestock, since some species have biocontrol potential or were shown to promote plant growth and to produce phytases, which are ... -
Spermatogenesis in the parasitoid Diachasmimorpha longicaudata (Hymenoptera: Braconidae)
(2017)The study of spermatogenesis in Hymenoptera is limited to few taxa due to limitations to access the material in the right stage for analysis. The information available up to now states that the gametogenesis in males ... -
Spontaneous Mutations in the Nitrate Reductase Gene napC Drive the Emergence of Eco-friendly Low-N2O-Emitting Alfalfa Rhizobia in Regions with Different Climates
(Springer, 2020)We have recently shown that commercial alfalfa inoculants (e.g., Sinorhizobium meliloti B399), which are closely related to the denitrifier model strain Sinorhizobium meliloti 1021, have conserved nitrate, nitrite, and ... -
Spontaneous photosensitization by Heterophyllaea pustulata Hook. f. (Rubiaceae), in sheep from Northwestern Argentina
(2017-10)Heterophyllaea pustulata Hook. f. (Rubiaceae) is a phototoxic plant. It grows in the Andean area of northwest of Argentina, and it causes significant economic losses in the livestock. This plant induces dermal lesions by ... -
Spontaneous virus reactivation in cattle chronically infected with bovine leukemia virus
(BioMed Central, 2019)Background: The absence of virus expression during the chronic stage of bovine leukemia virus (BLV) infection and its reactivation upon ex vivo culture has become a long-lived Dogma. During the chronic stage of BLV ... -
SSRs, SNPs and DArTs comparison on estimation of relatedness and genetic parameters’ precision from a small half-sib sample population of eucalyptus grandis
(2016)Simple sequence repeats (SSR) are the most widely used molecular markers for relatedness inference due to their multi-allelic nature and high informativeness. However, there is a growing trend toward using high-throughput ... -
Stability and fragmentation versus demographic expansion: different phylogeographic patterns in closely related sympatric legumes (Senna) from arid and semi-arid zones of mid-latitude South America
(Oxford University Press, 2021-03-01)This is the first comparative research in which phylogeographical patterns and present and palaeoclimatic distribution were investigated in desert plants that inhabit the Argentinian Monte and Chaco biogeographic provinces. ... -
Stable infection of a bovine mammary epithelial cell line (MAC-T) with bovine leukemia virus (BLV)
(Elsevier, 2018)Bovine leukemia virus (BLV) is a retrovirus that affects cattle causing a lymphoproliferative disease. BLV infection has been associated with misbalance of the immune response causing a higher incidence of other infections. ... -
Stable symbiotic nitrogen fixation under water-deficit field conditions by a stress-tolerant alfalfa microsymbiont and its complete genome sequence : Short communication
(2017-12)We here characterized the stress-tolerant alfalfa microsymbiont Sinorhizobium meliloti B401. B401-treated plants showed high nitrogen fixation rates under humid and semiarid environments. The production of glycine betaine ... -
