Phylogenetic analysis of North American Rhagoletis (Diptera: Tephritidae) and related genera using mitochondrial DNA sequence data

Molecular Phylogenetics and Evolution
B A McPheron, H Y Han

Abstract

Partial sequences (approximately 850 bp) of the mitochondrial 16S ribosomal RNA gene were determined for 21 members of the fruit fly genus Rhagoletis and 6 related tephritid taxa by sequencing DNA amplified by the polymerase chain reaction. Sequences were highly A + T rich, with an average G + C content of 19.2%. Sequence divergence ranged from 0 to 11.7% among the included taxa. Sequences were used to reconstruct the phylogeny of this group of flies with neighbor-joining and maximum parsimony methods. A group of 18 North American Rhagoletis species formed a monophyletic clade, and three morphologically based species groups were identified with strong statistical support. Relationships among the species groups were partially resolved. The tabellaria species group appears to be paraphyletic with respect to the pomonella species group, in contrast to previous allozyme analyses that united the cingulata and pomonella groups. The relations of the North American clade to other genera within the tribe Carpomyini were not clearly resolved. Rhagoletis striatella, a North American species that uses members of the tomato family (Solanaceae) as a larval host, may be more closely associated with South American Rhagoletis species and relate...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
