Adaptations of Drosophila and Yeasts: their Interactions with the Volatile 2-propanol in the Cactus-Micro organism-Drosophila Model System

The interactions of yeasts growing in decaying cactus tissue with and without 2-propanol were studied with respect to the costs and benefits provided to three cactophilic Drosophila species (D. mojavensis, D. arizonensis and D. buzzatit). Two common cactus yeasts, Candida sonorensis and Cryptococcus cereanus, which can tolerate and metabolize 2-propanol, provide benefits to the three Drosophila species in the presence of the alcohol, as compared with another common cactus yeast, Pichia cactophila, which has less tolerance and cannot metabolize 2-propanol.

Drosophila Model

Like all invertebrates, flies such as Drosophila lack an adaptive immune system and depend on their innate immune system to protect them against pathogenic microorganisms and parasites. In recent years, it appears that the nervous systems of eucaryotes not only control animal behavior but also cooperate and synergize very strongly with the animals’ immune systems to detect and fight potential pathogenic threats, and allow them to adapt their behavior to the presence of microorganisms and parasites that coexist with them. This review puts into perspective the latest progress made using the Drosophila model system, in this field of research, which remains in its infancy.

And Function

Abstractcis-regulatory sequences known as enhancers play a key role in regulating gene expression. Evolutionary changes in these DNA sequences contribute to phenotypic evolution. The Drosophila yellow gene, which is required for pigmentation, has emerged as a model system for understanding how cis-regulatory sequences evolve, providing some of the most detailed insights available into how activities of orthologous enhancers have diverged between species. Here, we examine the evolution of yellow cis-regulatory sequences on a broader scale by comparing the distribution and function of yellow enhancer activities throughout the 5’ intergenic and intronic sequences of Drosophila melanogaster, Drosophila pseudoobscura, and Drosophila willistoni. We find that cis-regulatory sequences driving expression in a particular tissue are not as modular as previously described, but rather have many redundant and cryptic enhancer activities distributed throughout the regions surveyed. Interestingly, cryptic enhancer activities of sequences from one species often drove patterns of expression observed in other species, suggesting that the frequent evolutionary changes in yellow expression observed among Drosophila species may be facilitated by gaining and losing repression of pre-existing cis-regulatory sequences.
