Abstract
The ornamental fish Amatitlania nigrofasciata, known as the convict or zebra cichlid, is a small Central American tropical freshwater fish that also serves as a model for behavioural studies. Its phylogenetic relationship with other cichlids in the tribe Heroini remains unclear. Here, we sequenced the mitogenome of A. nigrofasciata. The mitogenome spans 16,529 bp and includes the standard complement of 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes, and one D-loop region, with the same order and strand distribution as those of other cichlids. Phylogenetic analysis of the 13 PCGs showed that A. nigrofasciata is more closely related to Amphilophus, in a clade including Parachromis, Petenia, and Cryptoheros, with this clade forming a core group of amphilophines within the cichlid tribe Heroini.
期刊介绍：
The journal retains its traditional interest in evolutionary research that is of relevance to geneticists, even if this is not explicitly genetical in nature. The journal covers all areas of genetics and evolution,including molecular genetics and molecular evolution.It publishes papers and review articles on current topics, commentaries and essayson ideas and trends in genetics and evolutionary biology, historical developments, debates and book reviews. From 2010 onwards, the journal has published a special category of papers termed ‘Online Resources’. These are brief reports on the development and the routine use of molecular markers for assessing genetic variability within and among species. Also published are reports outlining pedagogical approaches in genetics teaching.
