| A. Bastías, R. Almada, P. Rojas, J.M. Donoso, P. Hinrichsen, and B. Sagredo. 2016. Aging gene pathway of microRNAs 156/157 and 172 is altered in juvenile and adult plants from in vitro propagated Prunus sp. Cien. Inv. Agr. 43(3):429-441. In vitro culture is a very popular technique to mass propagate valuable plant genotypes, including Prunus sp. cultivars. Plants that undergo tissue culture processes often change their morphology and behavior due to the "rejuvenation" caused by the plant growth regulators included in the medium. To evaluate the effects of rejuvenation by tissue culture in Prunus sp., the expression patterns of the aging gene pathway described in plant models, which include the highly conserved microRNA (miRNA or miR) 156/157 and 172... |

| Doce cultivares y líneas de arroz (Oryza sativa L.) desarrollados por el programa de fitomejoramiento del Instituto de Investigaciones Agropecuarias (INIA), Centro Regional de Investigación Quilamapu, fueron caracterizados genéticamente mediante amplificación de fragmentos polimórficos (AFLP). De 21 combinaciones ensayadas, sólo 16 fueron informativas, generando un total de 667 amplicones, 94 de ellos polimórficos (14,4%), con un rango entre 9 y 33% de polimorfismo por combinación. Esto indica que el material manejado por el programa de INIA presenta un bajo nivel de diversidad genética comparado tanto con germoplasma silvestre de la especie como con aquel usado por otros programas de fitomejoramiento de la especie. Los amplicones polimórficos detectados... |

| Currently, many monovarietal vineyards present a minority of mixed cultivars. Some of these cultivars are unknown and could represent an opportunity to discover new and potentially useful genotypes both for research and production purposes. In a 'Carmenère' vineyard planted in 1994 in Palmilla (Colchagua Valley, Chile), a minority presence of other cultivars was found. The present work covers for the first time the identification and characterization of one of these cultivars, which presented a very poor fruit set. Through classic ampelography, it was not possible to associate the studied cultivar with any known cultivar in Chile. However, through a simple sequence repeats (SSR) comparison against the database of the INRA Germplasm Repository "Domaine de... |

| The genetic characterization of 117 peach and nectarine cultivars (Prunus persica (L.) Batsch) using microsatellite (SSR) markers is presented. Analyzed genotypes include the complete list of cultivars under intellectual property (IP) protection in Chile. One hundred and two out of the 117 cultivars under study could be identified using only 7 SSRs. Other 5 cultivars were differentiated using 3 additional markers, but 5 pairs of genotypes were not differentiable. The average expected heterozygosity for the set of markers was 0.55, ranging from 0.28 in BPPCT-008 to 0.81 in CPPCT-022, with an F value of 0.37. A Neighbor-Joining dendrogram showed that, with few exceptions, peaches and nectarines clustered separately. These results are the basis for the... |
