The rice Xa21 gene, which confers resistance to Xanthomonas oryzae pv. oryzae race 6, was isolated by positional cloning. Fifty transgenic rice plants carrying the cloned Xa21 gene display high levels of resistance to the pathogen. The sequence of the predicted protein, which carries both a leucine-rich repeat motif and a serine-threonine kinase-like domain, suggests a role in cell surface recognition of a pathogen ligand and subsequent activation of an intracellular defense response… 

The rice bacterial blight resistance gene xa5 encodes a novel form of disease resistance.

Sequencing of TFIIAgamma inresistant and susceptible isolines revealed two nucleotide substitutions resulting in an amino acid change between resistant and susceptible cultivars.

Expression of Xa1, a bacterial blight-resistance gene in rice, is induced by bacterial inoculation.

Interestingly, Xa1 gene expression was induced on inoculation with a bacterial pathogen and wound, unlike other isolated resistance genes in plants, which show constitutive expression, suggesting that the induced expression may be involved in enhancement of resistance against the pathogen.

A model for the mode of action of Xa21 is proposed and the current knowledge of the modular basis of resistance in rice to bacterial leaf blight and blast is summarized.

Structure, function, and evolution of disease resistance genes in rice.

Sequence analysis of seven members of the Xa21 gene family at the locus suggests that duplication, recombination, and transposition have occurred during the evolution of this gene family.

A pair of orthologs of a leucine-rich repeat receptor kinase-like disease resistance gene family regulates rice response to raised temperature

Results suggest that the RKe locus is involved in rice response to raised temperature, and the LRR domain of RKe protein appears to be important to sense increased temperature.

Xa26, a gene conferring resistance to Xanthomonas oryzae pv. oryzae in rice, encodes an LRR receptor kinase-like protein.

Sequence analysis revealed that IRBB3 and Zhachanglong lines that are resistant to a broad range of Xoo strains, also carry Xa26, and results suggest that the resistance conferred by Xa 26 is influenced by the genetic background.

Xa21D Encodes a Receptor-like Molecule with a Leucine-Rich Repeat Domain That Determines Race-Specific Recognition and Is Subject to Adaptive Evolution

Both functional and evolutionary evidence indicates that the Xa21D LRR domain controls race-specific pathogen recognition.

A receptor like kinase gene with expressional responsiveness on Xanthomonas oryzae pv. oryzae is essential for Xa21-mediated disease resistance

This study reveals that the LRR-RLK gene XIK1 is Xoo-responsive and positively regulates Xa21-mediated disease resistance, and that expression is associated with plant development.



Map-based cloning of a protein kinase gene conferring disease resistance in tomato.

A yeast artificial chromosome clone that spans the Pto region was identified and used to probe a leaf complementary DNA (cDNA) library, suggesting a role for Pto in a signal transduction pathway.

Isolation of the tomato Cf-9 gene for resistance to Cladosporium fulvum by transposon tagging.

The predicted protein shows homology to the receptor domain of several receptor-like protein kinases in Arabidopsis, to antifungal polygalacturonase-inhibiting proteins in plants, and to other members of the leucine-rich repeat family of proteins.

Three distinct receptor-like protein kinase (RLK) cDNA clones from Arabidopsis thaliana have now been identified and suggest that each plays a distinct and possibly important role in cellular signaling in plants.

Inheritance of resistance to bacterial blight in rice cultivar Cas 209

The mode of inheritance of resistance in rice cultivar Cas 209 to bacterial strain PX086, a representative of race II of Xanthomonas campestris pv. oryzae in the Philippines, was studied. The

Molecular genetics of plant disease resistance

These findings suggest that plants may have evolved common signal transduction mechanisms for the expression of resistance to a wide range of unrelated pathogens.

Molecular cloning of a putative receptor protein kinase gene encoded at the self-incompatibility locus of Brassica oleracea.

The S receptor kinase (SRK) gene is described, a previously uncharacterized gene that resides at the S locus that exhibits striking homology to the secreted product of the S-locus glycoprotein (SLG) gene.

FIL2, an extracellular Leucine-Rich Repeat protein, is specifically expressed in Antirrhinum flowers.

Northern and Western blot analyses showed that FIL2 in wild-type Antirrhinum flowers is expressed weakly in the petals and more abundantly in the reproductive organs; the gene is active in the filaments and anthers of stamens, and in the stigma and transmitting tissue of the carpels.

The TMK1 gene from Arabidopsis codes for a protein with structural and biochemical characteristics of a receptor protein kinase.

Genomic and cDNA clones that code for a protein with structural and biochemical properties similar to the receptor protein kinases from animals were obtained from Arabidopsis, and the gene coding for this receptor-like transmembrane kinase was designated TMK1.

RFLP mapping of genes conferring complete and partial resistance to blast in a durably resistant rice cultivar.

This study illustrates the usefulness of RI lines for mapping a complex trait such as blast resistance and suggests that durable resistance in the traditional variety, Moroberekan, involves a complex of genes associated with both partial and complete resistance.

Cloning and characterization of the gene encoding the endopolygalacturonase-inhibiting protein (PGIP) of Phaseolus vulgaris L.

The nucleotide and deduced amino acid sequences of the PGIP gene showed no significant similarity with any known databank sequence and were successfully utilized as primers in a polymerase chain reaction (PCR) with total DNA of P. vulgaris as a template.
