1. 11. Controlling Fusarium Head Blight in oat

   Författare :Alfia Khairullina; Tillämpad biokemi; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; FHB; oat; UDP-glucosyltransferase; deoxynivalenol; mycotoxins; biocontrol; Clonostachys rosea; Fusarium head blight; Fusarium graminearum; endophytes;

   Sammanfattning : Oats (Avena sativa) is a versatile crop grown worldwide for animal feed and human consumption. Humanoat consumption has recently risen due to its various health benefits. However, oats are susceptible toFusarium head blight (FHB) caused by various Fusarium fungi. FHB reduces yield and leads to mycotoxinaccumulation. LÄS MER

3. 12. Monitoring important soil-borne plant pathogens in Swedish crop production using real-time PCR

   Författare :Charlotta Almquist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : The global demand for food will increase considerably in the nearest future and among the major constraints to agricultural productivity are biotic stresses caused by microorganisms. In this thesis, the causal agents of four of the most important soil-borne diseases threatening the Swedish production of oilseed rape, sugar beets and red clover were selected as targets for developing diagnostic assays using real-time PCR.

4. 13. Opportunities in small population breeding in black cottonwood : or The little population that could

   Författare :Rami-Petteri Apuli; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Small and structured populations are problematic for breeding due to low levels of genetic variability and increased levels of linkage disequilibrium (LD). The increased LD causes problems with utilization of common genomic tools and may lead into increased accruement of deleterious alleles through the intense selection and bottlenecks characteristic of breeding.

5. 14. The genetic basis for adaptation in natural populations

   Författare :Sangeet Lamichhaney; Leif Andersson; Carl-Johan Rubin; Alvaro Martinez Barrio; Henrik Kaessmann; Uppsala universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Adaptive evolution; Atlantic herring; ecological adaptation; seasonal reproduction; TSHR; Darwin’s finches; natural selection; beak; ALX1; HMGA2; ruff; lek; inversion; HSD17B2; MC1R;

   Sammanfattning : Many previous studies in evolutionary genetics have been based on few model organisms that can be reared at ease in the laboratory. In contrast, genetic studies of non-model, natural populations are desirable as they provide a wider range of adaptive phenotypes throughout evolutionary timescales and allow a more realistic understanding of how natural selection drives adaptive evolution.

7. 15. Population structure and pathogenicity evolution of Phytophthora infestans affects epidemiology and management of late blight disease

   Författare :Anne Njoroge; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Sound management of late blight, the disease caused by the notorious oomycete pathogen Phytophthora infestans (Mont.) de Bary, is dependent on the pathogen’s population biology. However, for P. LÄS MER
