Abstract:

This paper developed an approach to inferring gene evolution parameters and general genome distances under gene loss, birth, and lateral gene transfer using extended gene content. Simulation results indicated that, even with small number of gene families, with extended gene content information general genome distances under LGT can be well estimated using the developed. We applied the new method to 13 genome microbial complete genomes. By comparing the results from the new approach to those from others, the new method is useful to study the universal tree of life and also to reveal the evolution pattern.
