Use of it and polynucleotides to modulate the defense response of the plant

摘要

(57) Mlo gene of [summary] barley, mlo mutants, as well as rice and homologs from other species, including Arabidopsis thaliana, to allow adjustment of the pathogen defense response of the plant. Polypeptide and nucleic acid is used in the production of transgenic plant (is stimulated in particular) that pathogen defense response is adjusted. Various approaches to enable the diagnostic measurement of the presence of resistance or susceptibility alleles in plants. Can be identified using assays that require a fragment thereof said protein or a compound capable of modulating a protective response by interacting with mlo or protein Mlo.
