Gene acquisition in eukaryotes

A Cyanobacterial Gene in Nonphotosynthetic Protists—An Early Chloroplast Acquisition in Eukaryotes?

Since the incorporation of mitochondria and chloroplasts (plastids) into the eukaryotic cell by endosymbiosis, genes have been transferred from the organellar genomes to the nucleus of the host, via an ongoing process known as endosymbiotic gene transfer. Accordingly, in photosynthetic eukaryotes, nuclear genes with cyanobacterial affinity are believed to have originated from endosymbiotic gene...

Gene Transfer: Gene Swapping Craze Reaches Eukaryotes

Recent studies have provided evidence for gene transfers from prokaryotes to eukaryotes and between eukaryotes. The mechanisms and frequencies of these transfers remain the subject of speculation, but the findings provide ample reason to seriously consider interspecies gene transfer as an important evolutionary process in eukaryotes.

Gene-finding approaches for eukaryotes.

The goal of this paper is to introduce the methods commonly used for predicting protein-coding regions in eukaryotic DNA, primarily for the benefit of those not familiar with the topic. This is not meant as a comprehensive review, nor do I describe in detail the underlying mathematical formalism. Those seeking additional information are encouraged to read some recent reviews (Fickett 1996; Clav...

Nutrient-regulated gene expression in eukaryotes.

The recognition of changes in environmental conditions, and the ability to adapt to these changes, is essential for the viability of cells. There are numerous well characterized systems by which the presence or absence of an individual metabolite may be recognized by a cell. However, the recognition of a metabolite is just one step in a process that often results in changes in the expression of...
