  1. 1. Identifying Genetic Causes of Hybrid Necrosis in Arrabidopsis lyrata

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

    Author : Carlos Valbuena-Gonzalo; [2019]
    Keywords : ACD6; deleterious gene interactions; DM9; dwarfism; microsatellites;

    Abstract : Deleterious gene interactions due to accumulation of individual genetic variations between different lineages are a cause of population diversification by creating reproductive barriers that ultimately lead to differentiation of species. One type of deleterious interactions is called “hybrid necrosis”, in which epistatic interactions between some plant immunity genes (usually very variable) cause autoimmunities that produce a necrotic and dwarf phenotype.

  3. 2. The use of endogenous retroviruses as markers to describe the genetic relationships among some local Swedish sheep breeds

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

    Author : Robert Mukiibi; [2014]
    Keywords : Indigenous Swedish breeds; enJSRV; primitive; endogenous; polymorphism; proviruses;

    Abstract : The present modern sheep is believed to have evolved from its wild ancestors 2.5 million years ago. Furthermore archeological evidence suggest that sheep has been domesticated by man since 8500-9000 years BC for their beneficial products to man including; milk, meat, skin and wool. READ MORE

  4. 3. Variation in frequency of alleles in the MTNR1A gene with possible impact on ability of ewes to show oestrus out of season

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

    Author : Alexander Falk; [2013]
    Keywords : Sheep; out-of-season breeding; MTNR1A; DNA-sequencing;

    Abstract : In Swedish sheep industry it is desired to have lambs slaughtered evenly distributed over the year. Swedish sheep are generally seasonal breeders with lambs born in the spring and slaughtered in the autumn. Some of the breeds, e.g. READ MORE

  5. 4. Microsatellite marker-based genetic diversity analysis and developing synthetic varieties in Alfalfa (Medicago sativa L.)

    University essay from SLU/Plant Breeding and Biotechnology (until 121231)

    Author : Maksatbek Amanov; [2012]
    Keywords : Alfalfa; genetic diversity; Kyrgyzstan; microsatellite; SSR; synthetic variety;

    Abstract : Cultivated alfalfa (Medicago sativa L.) is an allogamous autotetraploid species with 2n = 4x = 32 chromosomes. Alfalfa is the most cultivated forage legume in the world mainly due to its wide adaptation to diverse environmental conditions and efficient nitrogen fixation ability. Kyrgyzstan is among the major alfalfa producing countries. READ MORE

  6. 5. Fine mapping of resistance against root aphids in sugar beet

    University essay from SLU/Plant Breeding and Biotechnology (until 121231)

    Author : Emma Leijman; [2011]
    Keywords : Resistance; Sequencing; Mapping; Molecular marker; Single-nucleotide polymorphism; SNP; Genome sequence; Breeding; Root aphids; Pemphigus betae; Sugar beet;

    Abstract : Sugar beet, Beta vulgaris, is an important crop for the global sugar industry being one of the two major crops cultivated for sugar production. In the USA, the sugar beet root aphid, Pemphigus betae, is a regionally occurring pest which damages sugar beets by feeding on their secondary roots which results in reduced biomass and hence a lower yield.
