Transcriptome assembly and candidate genes involved in nutritional programming in the swordtail fish <i>Xiphophorus multilineatus</i>.

ABSTRACT:

Background

Nutritional programming takes place in early development. Variation in the quality and/or quantity of nutrients in early development can influence long-term health and viability. However, little is known about the mechanisms of nutritional programming. The live-bearing fish Xiphophorus multilineatus has the potential to be a new model for understanding these mechanisms, given prior evidence of nutritional programming influencing behavior and juvenile growth rate. We tested the hypotheses that nutritional programming would influence behaviors involved in energy homeostasis as well gene expression in X. multilineatus.

Methods

We first examined the influence of both juvenile environment (varied in nutrition and density) and adult environment (varied in
