Última DNA sequence variation of drought-response candidate genes in Austrocedrus chilensis Electron. J. Biotechnol. Pomponio,María F; Torales,Susana; Gallo,Leonardo A; Pastorino,Mario J; Marchelli,Paula; Cervera,María Teresa; Poltri,Susana Marcucci. Background: Austrocedrus chilensis (D. Don) Pic. Ser. et Bizzarri commonly known as Patagonian cypress is a member of the Cupressaceae family, characterized by a high adaptive potential for growing in marginal areas and good timber quality. The species grows over a wide area and under a wide range of rainfall. This study assessed adaptive genetic variation at SNP level in candidate genes involved in response to drought stress. Results: A total of 18 single nucleotide polymorphisms (SNPs) were found among 1,428 bp. Average nucleotide diversity value (π = 0.00312) was similar to those previously reported in other Cupressaceae. The Fst average among genes and populations was 0.163 and the lowest differentiation was observed in continuous and humid...

The northernmost 'robles' of Argentina, located in Lagunas de Epulauquen (northwest Patagonia), are considered a population of Nothofagus obliqua, even though they differ in some respects from individuals of other populations of the species. In order to analyse a possible genetic basis of their distinctive character, we revised previous information and added new evidence based on biochemical (isozyme) and molecular (chloroplast DNA and nuclear microsatellite) markers, as well as quantitative trait variation (seed traits, leaf morphology, plant architecture and field performance). The comparison of Lagunas de Epulauquen specimens with specimens from other areas in Argentina demonstrated their genetic distinction. Glacial history, in conjunction with...
