The complete mitochondrial genome of Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) collected in Korean peninsula.

ABSTRACT: Aphid gosypii Glover, 1877 is a widely recognized economically important aphid species in the world. We have determined mitochondrial genome of A. gossypii collected in Korean peninsula. The circular mitogenome of A. gossypii is 15,872?bp including 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNAs, and a single control region of 627?bp. The base composition was AT-biased (83.8%). In comparison of Chinese A. gossypii mitochondrial genomes with that of Korean sample, 61 single nucleotide polymorphisms and 3 insertions and deletions were identified, presenting lower level of those of Nilaparvata lugens, Laodelphax striatellus, and Chilo suppresallis.

Project description:Insects harbor a wide variety of microorganisms that form complex and changing communities and play an important role in the biology and evolution of their hosts. Aphids have been used as model organisms to study microorganism-insect interactions. Almost all aphids are infected with the obligate endosymbiont Buchnera aphidicola and can host different bacteria that allow them to acquire traits of agronomic importance, such as resistance to high temperatures and/or defense against natural enemies. However, the bacterial communities of most aphid species remain poorly characterized. In this study, we used high-throughput DNA sequencing to characterize the bacterial communities of Aphis gossypii and Myzus persicae from two cultivable pepper species, Capsicum frutescens (Tabasco variety) and C. annuum (Cayenne variety), in four localities of southwestern Colombia. In addition, we evaluated the dynamics of A. gossypii-associated microorganisms on a seasonal basis. Our results show that the bacterial communities of A. gossypii and M. persicae are dominated by the primary endosymbiont B. aphidicola, while the presence of the facultative symbiont Arsenophonus sp. was only detected in one A. gossypii population from cayenne pepper. In addition to these two known symbionts, eight bacterial OTUs were identified that presented a frequency of 1% or more in at least one of the analyzed populations. The results show that the bacterial communities of aphids associated with pepper crops appears to be structured according to the host aphid species and the geographical location, while no differences were observed in the diversity of bacteria between host plants. Finally, the diversity and abundance of the A. gossypii bacterial community was variable among the four sampling points evaluated over the year and showed a relation with the aphid's population dynamics. This study represents the first approach to the knowledge of the bacterial community present in chili pepper aphids from Colombia. Nevertheless, more in-depth studies, including replicates, are required to confirm the patterns observed in the microbial communities of aphids from pepper crops.
