Sammanfattning : Plant growth promoting rhizobacteria are beneficial microbes able to induce plant stress tolerance and antagonise plant pathogens. The present study showed that wheat seedlings pre-treated with Bacillus thuringiensis AZP2 had better tolerance to severe drought stress and showed 78% greater plant biomass and five-fold higher survivorship compared to wheat seedlings not treated with the bacterium.

Sammanfattning : Somatic embryogenesis is an attractive method to propagate conifers vegetatively. However, many species belonging to Pinus are recalcitrant to somatic embryo development. The overall aim of this thesis has been to gain a better understanding of the developmental pathway leading to cotyledonary somatic embryos of Scots pine (Pinus sylvestris). LÄS MER

Sammanfattning : This thesis deals with the digestion and metabolism of carbohydrates in Arctic charr, Eurasian perch and tilapia. Two sources of carbohydrates, native starch (wheat) and chitin (zygomycete biomass), were evaluated. Gut tissue of Arctic charr displayed significant chitinase activity, of both endo- and exo-chitinase forms. LÄS MER

In this context, adjuvants have a key role in vaccines by stimulating the innate immunity and thereby enhancing and shaping the subsequent adaptive immune response. LÄS MER
