Annotated Information
Gene Symbol
- Os11g0598500 <=> Pb1, OsPb1
Function
- Panicle blast 1 (Pb1) is a blast-resistance gene derived from the indica cultivar ‘Modan’. Pb1-mediated resistance, which is characterized by durability of resistance and adult/panicle blast resistance, has been introduced into elite varieties for commercial cultivation.
- Panicle blast 1 (Pb1) encoded a coiled-coil–nucleotidebinding- site–leucine-rich repeat (CC–NBS–LRR) protein. The Pb1 protein sequence differed from previously reported R-proteins, particularly in the NBS domain, in which the P-loop was apparently absent and some other motifs were degenerated.
Expression
- Pb1 transcript levels increased during the development of Pb1+ cultivars; this expression pattern accounts for their adult/panicle resistance.
Evolution
