Document Summary
Lecture 10: plant growth promoing bacteria life style. Transcripional response to sucrose mimic the plant-associated life style of the plant growth promoing endophyte enterobacter sp. Global major challenge: to increase food producion. Only 1-2% by plant breeding & biotechnology (not suicient) To achieve: required to increase by 10% or more of yield gains. The use of plant-associated microorganisms as plant growth promoing agents. As bioferilizer (to improve nutrient availability & uptake), biopesicides & bioinsecicides. Both bacteria & fungi: fungi (pgpf, bacteria (pgpb) Plantonic is the stage of individual life style: a single bacterial cell may loat or swim in a liquid medium. Bioilm formaion is the stage that bacterial cells sick to one another on a surface via extracellular polymeric substances (composed of polysaccharides, proteins & lipids) Siderophore producion (chelaing iron to make it available to the plant root) Control of plant diseases via induced systemic resistance (isr) & producion of ani-fungal metabolites.
