Abstract
Blast disease caused by Magnaporthe oryzae is one of the important biotic stresses of rice. So far more than 85 blast resistance genes have been identified of these more than 14 have already been cloned. A broad spectrum rice blast resistance gene Pi-k h was cloned from the rice line Tetep. The gene was named Pi-k h based on the earlier reports on its genetic analysis in various rice lines. However, with the advances in molecular genetics and genomics of rice, the Pik locus has now been mapped more precisely. Since there are two reports on the mapping of Pi-k h gene from different rice lines, there is some confusion in the naming of this gene. In this report the name of Pi-k h gene cloned from the rice line Tetep has been designated as per the standard guidelines of Committee on Gene Symbolization, Nomenclature and Linkage (CGSNL) and its physical location on rice chromosome 11, which is ∼2.5 Mbp away from the Pik locus mapped recently. Hence Pi-k h gene cloned from Tetep is now designated as Pi54.
