Deciphering signalling network in broad spectrum Near Isogenic Lines of rice resistant to Magnaporthe oryzae.

ABSTRACT: Disease resistance (R) genes like Pi9, Pita, Pi21, Pi54 are playing important role for broad spectrum blast resistance in rice. Development of near isogenic lines (NILs) using these type of broad spectrum genes and understanding their signalling networks is essential to cope up with highly evolving Magnaporthe oryzae strains for longer duration. Here, transcriptional-level changes were studied in three near-isogenic lines (PB1 + Pi1, PB1 + Pi9 and PB1 + Pi54) of rice resistant to blast infection, to find the loci that are unique to resistant lines developed in the background of Pusa Basmati 1 (PB1). The pathway analysis of loci, unique to resistant NILs compared to susceptible control revealed that plant secondary metabolite synthesis was the common mechanism among all NILs to counter agai
