  1. 1. Development of a DNA barcode for species identification of tuna

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Clara Nordquist; Jonathan Edwall; Leonora Eriksson; Nelly Mäkinen; Minna Sayehban; Matilda Styfberg; [2022]
    Keywords : Thunnini; D-loop; mitochondrial control region; CR; 16S; ATP8; COII; Cox2; CytB; COI; Cox1; ND2; NADH dehydrogenase 2;

    Abstract : Today, DNA-barcoding with the gene COI is regularly used in the identification of fish. However, this is not an adequate way of identifying species of tuna due to COI lacking sufficient interspecies divergence. This is problematic since fraud and mislabeling are a major concern within the fish and tuna industries. READ MORE

  3. 2. Vicia faba determinate and indeterminate inflorescence genotypes : comparison of genetic variation at TFL1 locus

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Jenny Östberg; [2021]
    Keywords : Faba bean; growth habit; TERMINAL FLOWER1; genetic marker; legume; mutant;

    Abstract : Faba bean (Vicia faba L.) plants usually express an indeterminate inflorescence growth habit regulated by the gene TERMINAL FLOWER1 (TFL1) which allows the apical meristem to continuously produce new vegetative and reproductive plant parts. In turn, this prolongs the growth and flowering period and causes an uneven ripening of the pods. READ MORE

  4. 3. Resistens mot Caprin artrit encefalit och genetisk variation i αS1-kasein genen (CSN1S1) hos svenska getter

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Sofie Gunnarsson; [2020]
    Keywords : Kaprin artrit encefalit; maedi visna; virus; sjukdomsförekomst; CCR5; CSN1S1; kasein; αS1-kasein; osttillverkning; kopplingsojämvikt; genetisk variation; allelfrekvens;

    Abstract : Caprin artrit encefalit (CAE) och låga koncentrationer av αS1-kasein (αS1-kn) i mjölken är två problemområden inom den svenska getproduktionen. Caprin artrit encefalit är en virussjukdom som liknar humant immunbristvirus (HIV) hos människa och maedi visna hos får. READ MORE

  5. 4. Identification of core gut bacterial community of royal pair of a fungus-growing termite, Macrotermes natalensis

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Jayalal Kalathilparambil Jayanthan; [2019]
    Keywords : ;

    Abstract : Approximately 30 million years ago, ancestors of fungus-growing termites started an obligate mutualistic relationship with a Basidiomycete fungus Termitomyces. The success of this obligate relation is the division of labour and reliance on termite caste gut microbial symbionts. READ MORE

  6. 5. Studying genetics of leaf shape variation in Arabidopsis lyrata

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Carina Kvernes Macpherson; [2019]
    Keywords : Arabidopsis lyrata; Arabidopsis arenosa; leaf shape; RCO genes; genotype; phenotype; gene sequence variation;

    Abstract : The relationship between leaf and its environment has resulted in a tremendous diversification of leaf shape within and between plants species, which is important to cope with the differing environmental conditions. Arabidopsis lyrata is a prime model plant that shows leaf shape variation within species and between related species. READ MORE
