AI Article Synopsis

  • * The study examined polyandry in Queensland fruit flies in New South Wales and Queensland using advanced genetic techniques.
  • * Results showed a much higher rate of polyandry in New South Wales (80%) compared to Queensland (26.1%), highlighting the need to consider regional differences in pest management strategies like sterile insect technique (SIT).

Article Abstract

Female insects commonly have more than one mate during a breeding period ('polyandry'), storing and using sperm from multiple males. In addition to its evolutionary significance, insect polyandry has practical implications for pest management that relies on the sterile insect technique (SIT). The Queensland fruit fly, (Froggatt), is a major horticultural pest in Australia, and outbreaks are managed by SIT in some regions. The present study provides the first evidence for polyandry in female from field populations from New South Wales (NSW) and Queensland (QLD) through multi-locus genotyping (ten microsatellite markers in four fluorescent multiplexes) of the stored sperm in ovipositing females. Polyandry level was significantly higher in the NSW collection (80.0 %) than the QLD collection (26.1 %), suggesting substantial regional and/or temporal variation. These findings have important implications for the use of SIT to suppress populations and to eradicate outbreaks.

Background: The high burden of malaria in Africa is largely due to the presence of competent and adapted Anopheles vector species. With invasive Anopheles stephensi implicated in malaria outbreaks in Africa, understanding the genomic basis of vector-parasite compatibility is essential for assessing the risk of future outbreaks due to this mosquito. Vector compatibility with P.

Single- and multi-locus genome-wide association study reveals genomic regions of thirteen yield-related traits in common wheat.

BMC Plant Biol

Genetic dissection of yield-related traits can be used to improve wheat yield through molecular design breeding. In this study, we genotyped 245 wheat varieties and measured 13 yield-related plant height-, grain-, and spike-related traits, in seven environments, and identified 778 loci for these traits by genome-wide association study (GWAS) using single- and multi-locus models. Among these loci, nine were major, of which seven were novel, including Qph/lph.

Multi-locus sequence typing (MLST) based on eight genes has become the method of choice for Borrelia typing and is extensively used for population studies. Whole-genome sequencing enables studies to scale up to genomic levels but necessitates extended schemes. We have developed a 639-loci core genome MLST (cgMLST) scheme for Borrelia burgdorferi sensu lato (s.

Background: Intestinal schistosomiasis was confirmed endemic in Mangochi District, Malawi, in May of 2018 following an unexpected encounter with discreet populations of Biomphalaria spp. freshwater snails during routine malacological surveillance activities. Since then, only limited malacological surveillance of Biomphalaria has been carried out, and so the distribution of Biomphalaria populations in this area is currently unclear.

Genomic Epidemiology of ST81 in Multiple Hospitals in China.

Infect Drug Resist

December 2024

State Key Laboratory for Diagnosis and Treatment of Infectious Diseases, Collaborative Innovation Center for Diagnosis and Treatment of Infectious Diseases, The First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, Zhejiang, People's Republic of China.

Background: sequence type (ST) 81, mainly associated with ribotype (RT) 369, is a TcdA-negative and TcdB-positive genotype and a common ST found in China. Furthermore, ST81 strains are reported with highest resistance rates to many antimicrobial agents. However, given the potential for ST81 transmission, research into the epidemiological characteristics of this type of ST remain limited.
