Population genetics structure of glyphosate‐resistant Johnsongrass (Sorghum halepense L. Pers) does not support a single origin of the resistance
(Wiley, 2013-09)Single sequence repeats (SSR) developed for Sorghum bicolor were used to characterize the genetic distance of 46 different Sorghum halepense (Johnsongrass) accessions from Argentina some of which have evolved toward ... -
Population structure and genetic diversity characterization of a sunflower association mapping population using SSR and SNP markers
(BMC, 2015-02)Background: Argentina has a long tradition of sunflower breeding, and its germplasm is a valuable genetic resource worldwide. However, knowledge of the genetic constitution and variability levels of the Argentinean germplasm ... -
Potato snakin-1 gene enhances tolerance to Rhizoctonia solani and Sclerotinia sclerotiorum in transgenic lettuce plants
(Elsevier, 2018-10)Snakin-1 is a cysteine-rich antimicrobial peptide (AMP) isolated from potato tubers, with broad-spectrum activity. It belongs to the Snakin/GASA family, whose members have been studied because of their diverse roles ... -
Potato Snakin-1 Gene Silencing Affects Cell Division, Primary Metabolism, and Cell Wall Composition
(American Society of Plant Biologists, 2012-01)Snakin-1 (SN1) is an antimicrobial cysteine-rich peptide isolated from potato (Solanum tuberosum) that was classified as a member of the Snakin/Gibberellic Acid Stimulated in Arabidopsis protein family. In this work, a ... -
Potato snakin‑1: an antimicrobial player of the trade‑off between host defense and development
(Springer, 2020-07)Snakin-1 (SN1) from potato is a cysteine-rich antimicrobial peptide with high evolutionary conservation. It has 63 amino acid residues, 12 of which are cysteines capable of forming six disulfide bonds. SN1 localizes in the ... -
Pre-breeding studies in Panicum coloratum var. coloratum: Characterization using agro-morphological traits and molecular markers = Estudios de pre-mejoramiento genético en Panicum coloratum var. coloratum : caracterización usando marcadores moleculares y caracteres agro-morfológicos
(CIAT, 2018)Panicum coloratum var. coloratum is a native African perennial C4 grass, introduced to Argentina. It is tolerant of salinity and cold and has good forage production. The scarce genotypic and phenotypic information about ... -
Pre-columbian mycobacterial genomes reveal seals as a source of new world human tuberculosis
(Springer Nature, 2014-08)Modern strains of Mycobacterium tuberculosis from the Americas are closely related to those from Europe, supporting the assumption that human tuberculosis was introduced post-contact1. This notion, however, is incompatible ... -
Preparation of a working seed lot of BCG and quality control by PCR genotyping
(Asociación Argentina de Microbiología, 2010-04)The bacillus Calmette-Guérin (BCG) was obtained in 1920 after successive passages leading to the attenuation of a Mycobacterium bovis strain. For the following 40 years, BCG had been replicated, resulting in substrains ... -
Prevalence and species diversity of nontuberculous mycobacteria in drinking water supply system of Bahía Blanca City, Argentina
(Wolters Kluwer; Asian African Society of Mycobacteriology, 2019-06)Background: There is evidence that tap water is the vehicle through which nontuberculous mycobacteria (NTM) infect or colonize the human body. The objective of this study was to determine the presence and diversity of NTM ... -
