Assessing small RNA profles in potato diploid hybrid and its resynthesized allopolyploid reveals conserved abundance with distinct genomic distribution
Zavallo, Diego; Cara, Nicolás; Leone, Melisa; Crescente, Juan Manuel; Marfil, Carlos Federico; Masuelli, Ricardo Williams; Asurmendi, Sebastian (Springer, 2024-04)Allopolyploidy, a complex process involving interspecific hybridization and whole genome duplication, significantly impacts plant evolution, leading to the emergence of novel phenotypes. Polyploids often present phenotypic ... -
Avances en la mejora genética de tomate para industria = Advances in genetic breeding for processing tomatoes
Gallardo, Guillermo Santiago; Masuelli, Ricardo Williams; Ferrer, S. (Asociación Argentina Horticultura, 2013)En el 2001, en la EEA La Consulta, INTA, se comenzó un trabajo de mejora genética en tomate para industria, asistido por marcadores moleculares, con el objetivo principal de generar cultivares autopolinizadas, especialmente ... -
Changes in micro RNA expression in a wild tuber-bearing Solanum species induced by 5-Azacytidine treatment
Marfil, Carlos Federico; Asurmendi, Sebastian; Masuelli, Ricardo Williams (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 ... -
Comparison of two detection systems to reveal AFLP markers in plants
Cara, Nicolás; Marfil, Carlos Federico; Garcia Lampasona, Sandra Claudia; Masuelli, Ricardo Williams (2014-06)Since their development, AFLP (amplified fragment length polymorphism) markers have been used for a wide variety of analyses and, up to this day, are considered highly informative, robust, and reproducible molecular markers. ... -
Epigenetic patterns newly established after interspecific hybridization in natural populations of Solanum
Cara, Nicolás; Marfil, Carlos Federico; Masuelli, Ricardo Williams (Wiley, 2013-10)Interspecific hybridization is known for triggering genetic and epigenetic changes, such as modifications on DNA methylation patterns and impact on phenotypic plasticity and ecological adaptation. Wild potatoes (Solanum, ... -
Hybridization and polyploidization effects on LTR‑retrotransposon activation in potato genome
Gantuz, Magdalena; Morales Sanfurgo, Hugo Andres; Bertoldi, Maria Victoria; Ibañez, Verónica Noé; Duarte, Paola Fernanda; Marfil, Carlos Federico; Masuelli, Ricardo Williams (The Botanical Society of Japan, 2021-10-26)Hybridization and polyploidization are major forces in plant evolution and potatoes are not an exception. It is proposed that the proliferation of Long Terminal Repeat-retrotransposons (LTR-RT) is related to genome ... -
Pollen‐mediated gene flow from a commercial potato cultivar to the wild relative S. chacoense Bitter under experimental field conditions in Argentina
Capurro, Mauricio Antonio; Camadro, Elsa Lucila; Masuelli, Ricardo Williams (Wiley, 2013-12)The common potato, Solanum tuberosum ssp. tuberosum (tbr, 2n = 4x = 48; 4EBN), has many closely related wild tuber‐bearing species. Around 28 to 35 of them spontaneously grow in Argentina overlapping, in some areas, with ... -
Reproductive ecology and genetic variability in natural populations of the wild potato, Solanum kurtzianum
Marfil, Carlos Federico; Masuelli, Ricardo Williams (Wiley, 2014-03)The cultivated potato (Solanum tuberosum ssp. tuberosum) has more than 200 related wild species distributed along the Andes, adapted to a wide range of geographical and ecological areas. Since the last century, several ... -
Short‐term hybridisation activates Tnt1 and Tto1 Copia retrotransposons in wild tuber‐bearing Solanum species
Paz, Rosalia Cristina; Rendina González, Alejandra Pilar; Ferrer, M.S.; Masuelli, Ricardo Williams (2015-07)Interspecific hybridisation in tuber‐bearing species of Solanum is a common phenomenon and represents an important source of variability, crucial for adaptation and speciation of potato species. In this regard, the effects ...
