Abstract
Perception of chitin fragments (chitooligosaccharides) is an important first step in plant defense response against fungal pathogen. LysM receptor-like kinases (LysM RLKs) are instrumental in this perception process. LysM RLKs also play a role in activating transcription of chitin-responsive genes (CRGs) in plants. Mutations in the LysM kinase receptor genes or the downstream CRGs may affect the fungal susceptibility of a plant. Mutations in LysM RLKs or transgenes carrying the same may be beneficial in imparting resistance against fungal pathogens.
Claims16
A transgenic plant comprising a transgene, said transgene having at least 98% sequence identity to a LysM receptor kinase family gene having the sequence of SEQ ID No. 7, wherein the transgenic plant is derived from a host plant that is susceptible to fungal infection, and wherein the expression of said transgene renders the transgenic plant less susceptible to fungal infection as compared to said host plant.
A transgenic plant comprising a LysM receptor kinase family gene having at least one mutation, said mutated gene being derived from an endogenous wild-type LysM receptor kinase family gene having at least 98% sequence identity to SEQ ID No. 7.
A method for protecting a plant from fungal infection, comprising the step of introducing into said plant a transgene, said transgene having at least 95% sequence identity to a LysM receptor kinase family gene having the sequence of SEQ ID No. 7.
A method for protecting a plant from fungal infection, comprising the step of generating in said plant at least one mutation in a LysM receptor kinase family gene, said LysM receptor kinase family gene being endogenous to said plant, wherein said LysM receptor kinase family gene has at least 95% sequence identity to the polynucleotide having the sequence of SEQ ID No. 7.
