Molecular evidence of hybrid zones of Cedrela (Meliaceae) in the Yungas of Northwestern Argentina.

In the Yungas of Northwestern Argentina, three endangered species of Cedrela (C. angustifolia, C. saltensis, and C.

Effect of latitudinal gradient and impact of logging on genetic diversity of Cedrela lilloi along the Argentine Yungas Rainforest.

Cedrela lilloi C. DC. (cedro coya, Meliaceae), an important south American timber species, has been historically overexploited through selective logging in Argentine Yungas Rainforest.

Molecular identification of new varieties of Nierembergia linariaefolia (Graham), a native Argentinean ornamental plant.

Six Nierembergia linariaefolia clones were selected for ornamental traits during a native germplasm development program. For fingerprinting diagnosis, 13 anchored inter-simple sequence repeat (ISSR) primers and 6 amplified fragment length polymorphism (AFLP) primer-enzyme combinations were used. Both markers revealed high levels of polymorphism, enabling genetic discrimination of the accessions analyzed by using 443 informative ISSRs and 541 AFLP markers.

Selection strategy for a seedling seed orchard design based on trait selection index and genomic analysis by molecular markers: a case study for Eucalyptus dunnii.

Molecular genetic analysis was applied to 162 individuals of 37 half-sib selected families belonging to six provenances of Eucalyptus dunnii Maiden in a provenance/family trial. The individuals were selected by a trait selection index and genetic diversity criteria were later applied for designing seedling seed orchards. Genetic diversity and its distribution, as well as relationships among individuals, were assessed on the basis of nine microsatellite loci and 243 amplified fragment length polymorphism markers.
