Abstract Background Understanding the genetic architecture of ecologically relevant adaptive traits requires the contribution of developmental and evolutionary biology. The time to reach the age of...

Abstract Background The rapid evolution of genital morphology is a fascinating feature that accompanies many speciation events. However, the underlying patterns and explanatory processes remain to be...

The Xdh (rosy) gene is one of the best studied in the Drosophila genus from an evolutionary viewpoint. Here we analyze nucleotide variation in a 1875-bp fragment of the second exon of Xdh in...
Transpecific Polymorphisms in an Inversion Linked Esterase Locus in Drosophila buzzatii (2003)
Gómez, Gloria A., Hasson, Esteban
Nucleotide variation was studied in a 1.1 kb section of the coding region of an Esterase gene (Est-A) that maps in the center of the segments rearranged by polymorphic inversions in the cactophilic...

Inversions are portions of chromosome where the gene order is reversed relative to a standard reference orientation. Because of reduced levels of recombination in heterokaryotypes, inversions have a...

The Asr2 gene encodes a putative transcription factor that is up-regulated in leaves and roots of tomato plants exposed to water deficit stress. This gene was first cloned and characterized in a...

The Xdh (rosy) gene is one of the best studied in Drosophila from an evolutionary viewpoint. Here we analyze nucleotide variation in an ∼ 1875-bp fragment of the second exon of Xdh in Argentinian...

Developmental time and body size are two positively correlated traits closely related to fitness in many organisms including Drosophila. Previous work suggested that these two traits are involved in...

We tested for the occurrence of oviposition acceptance for different media prepared with cactus tissues of three alternative cactus hosts: Opuntia sulphurea, O. quimilo and Trichocereus terschekii...

Highland populations of several Drosophila species in Argentina were active early in the afternoon in the field as opposed to populations from a much warmer lowland site, where flies were mainly...

Inversion polymorphisms often have been associated with fitness variation. Cactophilic Drosophila buzzatii has been used widely for the study of the maintenance of chromosomal variation. The purpose...
