Análisis funcional de Snakin - 1 en plantas transgénicas de Solanum tuberosum
(Facultad de Agronomía, Universidad de Buenos Aires, 2015-04)Snakin-1 (SN1)es un péptido antimicrobiano rico en cisteínas aislado a partir de Solanum tuberosum que fue clasificado como miembro de la familia Snakin/GASA. Con el objetivo de estudiar el rol de SN1 in planta, se realizó ... -
Caracterización molecular y cariotípica de la variabilidad genética de germoplasma argentino de Solanum L.
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 1998)La papa cultivada se encuentra relacionada con un gran número de especies del género Solanum con las que frecuentemente se cruza. Por tal motivo, las aproximadamente 200 especies silvestres que producen tuberculo, constituyen ... -
Changes in micro RNA expression in a wild tuber-bearing Solanum species induced by 5-Azacytidine treatment
(2012-08)Phenotypic plasticity is often postulated as a principal characteristic of tuber-bearing wild Solanum species. The hypotheses to explore this observation have been developed based on the presence of genetic variation. In ... -
First complete genome sequence of potato leafroll virus from Argentina
(2017-07)In this study, we determined for the first time the complete genomic sequence of an Argentinian isolate of Potato leafroll virus (PLRV), the type species of the genus Polerovirus. The isolate sequenced came from a Solanum ... -
Genome-wide analysis of the snakin/GASA gene family in solanum tuberosum cv. Kennebec
(2016-04)Snakin/GASA proteins have been involved in different aspects of plant growth and development although their exact role is still intriguing. All of them maintain 12 cysteines of the C-terminus in highly conserved positions ... -
Genomic re-assessment of the transposable element landscape of the potato genome
(Springer, 2020-05)Transposable elements (TEs) are DNA sequences with the ability to autoreplicate and move throughout the host genome. TEs are major drivers in stress response and genome evolution. Given their significance, the development ... -
Identificación molecular de bacteria causante de pie negro y podredumbre blanda en papa en el cinturón verde de Córdoba capital
(Asociación Argentina de Microbiología, 2024-08-21)En muestreos realizados en marzo de 2022, en campos de producción de papa (Solanum tuberosum) del cinturón verde de la ciudad de Córdoba Capital, se detectaron plantas con síntomas de pie negro y podredumbre blanda. Estos ... -
Isolation and characterization of the tissue and development-specific potato snakin-1 promoter inducible by temperature and wounding
(Pontificia Universidad Catolica de Valparaiso, 2010-09)Snakin-1 (StSN1) is a broad-spectrum antimicrobial peptide isolated from Solanum tuberosum. Homologous proteins have been identified in a wide range of species but there is no apparent consensus in the roles they play. A ... -
The overexpression of antifungal genes enhances resistance to rhizoctonia solani in transgenic potato plants without affecting arbuscular mycorrhizal symbiosis
(Elsevier, 2019-10)The biological control of fungal diseases through the use of genetically modified (GM) plants could decrease the input of chemical pesticides. To overcome possible losses in potato (Solanum tuberosum) yield because of ... -
Overexpression of snakin-1 gene enhances resistance to Rhizoctonia solani and Erwinia carotovora in transgenic potato plants
(Wiley-Blackwell, 2008-05)Snakin‐1 (SN1), a cysteine‐rich peptide with broad‐spectrum antimicrobial activity in vitro, was evaluated for its ability to confer resistance to pathogens in transgenic potatoes. Genetic variants of this gene were cloned ... -
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 ... -
Snakin-1 affects reactive oxygen species and ascorbic acid levels and hormone balance in potato
(PLOS, 2019-03-25)Snakin-1 is a member of the Solanum tuberosum Snakin/GASA family. We previously demonstrated that Snakin-1 is involved in plant defense to pathogens as well as in plant growth and development, but its mechanism of action ... -
State of the art of genetic engineering in potato: from the first report to its future potential
(Frontiers Media, 2022-01)Potato (Solanum tuberosum L.) is a crop of world importance that produces tubers of high nutritional quality. It is considered one of the promising crops to overcome the challenges of poverty and hunger worldwide. However, ... -
Successful production of the potato antimicrobial peptide Snakin-1 in baculovirus-infected insect cells and development of specific antibodies
(2017)Background: Snakin-1 (StSN1) is a broad-spectrum antimicrobial cysteine-rich peptide isolated from Solanum tuberosum. Its biotechnological potential has been already recognized since it exhibits in vivo antifungal and ... -
