If you wish to cite MEGA in your publications, we suggest the following:
(1) When referring to MEGA in the main text of your publication, you may choose a format such as:
Phylogenetic and molecular evolutionary analyses were conducted using MEGA version 5 (Tamura, Peterson, Stecher, Nei, and Kumar 2011).
(2) When including a MEGA citation in the Literature Cited/Bibliography section, you may use the following:
Tamura K, Peterson D, Peterson N, Stecher G, Nei M, and Kumar S (2011) MEGA5: Molecular Evolutionary Genetics Analysis using Maximum Likelihood, Evolutionary Distance, and Maximum Parsimony Methods. Molecular Biology and Evolution (submitted).
