PY - 2020 DA - 2020/07/17 TI - Expansions and contractions in gene families of independently-evolved blood-feeding insects JO - BMC Evolutionary Biology SP - 87 VL - 20 IS - 1 AB - The blood-feeding behavior evolved multiple times in Insecta lineages and it represents an excellent opportunity to study patterns of convergent molecular evolution regarding this habit. In insects the expansion of some gene families is linked with blood-feeding behavior, but a wide study comparing the evolution of these gene families among different lineages is still missing. Here we gathered genomic data from six independently-evolved hematophagous lineages, aiming to identify convergent expansions and/or contractions of gene families in hematophagous lineages of insects.
