1. Deciphering mechanisms of Bacillus amyloliquefaciens mediated priming of plant growth and defense responses
Kandidat-uppsats, SLU/Department of Plant Biology (from 140101)Sammanfattning : Beneficial bacteria colonizing plant roots are capable of mediating improved plant growth and enhanced defense responses against biotic and abiotic stresses. Such colonization has been suggested to accumulate brassinosteroid (BR) levels but the mechanisms behind this is not yet completely understood. LÄS MER
2. Identification of Mutations in Genes Regulating Culm Length in Malting Barley
Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologiSammanfattning : Lodging, the tendency in barley to lie down on the ground when exposed to hail and heavy fertilising, is one of the most important traits that barley breeding is trying to remove from the barley cultivars. This may be an even greater challenge when future climate changes may lead to more extreme weather leading to more severe storms with heavy rain and hail. LÄS MER
3. The Arabidopsis – Plasmodiophora brassicae interaction : screening procedures and evaluation of mutant responses
Master-uppsats, SLU/Department of Plant Biology (from 140101)Sammanfattning : Clubroot, caused by the obligate biotrophic protist Plasmodiophora brassicae, is an important disease of Brassica oil and vegetable crops, and causes an estimated production loss of 10% worldwide. Infected root tissues develop swollen roots (clubroots) leading to wilting, stunting and premature ripening of the aboveground organs. LÄS MER
4. Priming as a strategy to enhance stress tolerance in plants with focus on the role of Brassinosteroid related genes
Kandidat-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)Sammanfattning : It is of interest to gain knowledge of the mechanisms operating behind priming, an important possible strategy to help plants handle stress. The hypothesis is that priming of Arabidopsis thaliana, as a result of colonization of roots using the beneficial bacteria Bacillus amyloliquefaciens, stimulates Brassinosteroid (BR) synthesis in plants leading to plant growth promotion and improved defense responses.

5. Role of Brassinosteroids in plant growth promotion and stress tolerance during primingmediated by beneficial bacteria
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)Sammanfattning : Brassinosteroids (BR) are plant hormones widely distributed throughout the plant kingdom inlow concentrations and with structural homology to animal and insect steroids. BR are involvedin numerous physiological processes, and they also fulfill an antagonistic role in anti-herbivorystructure formation in tomato (Campos et al., 2009). LÄS MER
