Identification of jumonjiC domain containing gene family among the Oryza species and their expression analysis in FL478, a salt tolerant rice genotype.

The jumonji (JMJ)-C domain containing proteins belong to histone demethylases family with the ability to demethylate the tri-methylated histone residues. They act as chromatin regulators to regulate many physiological functions in plants. The present study deals with the characterization of JMJ-C gene family members in wild as well as cultivated rice species and their expression analysis in salt tolerant rice genotype, FL478.

Phenotypic expression of blast resistance gene Pi54 is not affected by its chromosomal position.

This is a novel report in which chromosomal position of the rice blast resistance gene Pi54 was not found to affect significantly the resistance phenotype or morphological traits. Blast disease caused by Magnaporthe oryzae is a serious constraint in rice production at global level. Pi54 gene imparts resistance against M.
