1. 1. Mechanism of Action of the Plant Growth Promoting Bacterium Paenibacillus polymyxa

   Författare :Salme Timmusk; Gerhart Wagner; Janet Jansson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Plant growth promotion; Induced resistance; Biocontrol; Deleterious rhizobacterium; Mikrobiologi; Microbiology; Mikrobiologi;

   Sammanfattning : Paenibacillus polymyxa belongs to the group of plant growth promoting rhizobacteria (PGPR). Activities associated with P. polymyxa-treatment of plants in earlier experiments include, e.g. LÄS MER

3. 2. Studies on plant-microbe interaction to improve stress tolerance in plants for sustainable agriculture

   Författare :Shashidar Asari; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Biotic and abiotic stress factors have a major impact on plants and cause extensive losses to crop production. Bacteria that provide growth promotion and prime stress tolerance of plants have great potential to improve crop production and support durable and environmental friendly resource management.

4. 3. Molecular interactions between quinoa, the biocontrol agent Trichoderma and the pathogen Peronospora variabilis

   Författare :Oscar Miguel Rollano Penaloza; Molekylär cellbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chenopodium quinoa; Peronospora variabilis; Trichoderma harzianum; Molecular interactions; qRT-PCR; RNA-seq; Plant growth promotion; Chenopodium quinoa; Peronospora variabilis; Trichoderma harzianum; RNA-seq; qRT-PCR; molekylära interaktioner;

   Sammanfattning : Plants have developed complex molecular mechanisms to recognize and respond to the different microorganisms present in their surroundings. The most studied response mechanisms are plant defense responses. These defense response mechanisms share many similar components with the plant response mechanisms to beneficial microbes. LÄS MER

5. 4. Genomics and transcriptomics of plant beneficial Serratia spp

   Författare :Saraswoti Neupane; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Plant growth stimulation and antagonism against phytopathogens by rhizobacteria are widely recognised phenomena, but the variation in the underlying causal mechanisms between and within different bacterial taxa is still poorly understood. Some bacteria of the genus Serratia are known to be associated with plant roots, and have potential as possible biocontrol agents in agriculture. LÄS MER

7. 5. Use of rhizobacteria for the alleviation of plant stress

   Författare :Islam Ahmed Moustafa Abd El-Daim; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   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.
