| description | Background
Rice blast is a destructive disease caused by
Magnaporthe oryzae
, and it has a large impact on rice production worldwide. Compared with leaf blast resistance, our understanding of panicle blast resistance is limited, with only one panicle blast resistance gene,
Pb1
, isolated so far. The
japonica
cultivar Miyazakimochi shows resistance to panicle blast, yet the genetic components accounting for this resistance remain to be determined.
Results
In this study, we evaluated the panicle blast resistance of populations derived from a cross between Miyazakimochi and the Bikei 22 cultivar, which is susceptible to both leaf and panicle blast. The phenotypic analyses revealed no correlation between panicle blast resistance and leaf blast resistance. Quantitative trait locus (QTL) analysis of 158 recombinant inbred lines using 112 developed genome-wide and 35 previously reported polymerase chain reaction (PCR) markers revealed the presence of two QTLs conferring panicle blast resistance in Miyazakimochi: a major QTL,
qPbm11
, on chromosome 11; and a minor QTL,
qPbm9
, on chromosome 9. To clarify the contribution of these QTLs to panicle blast resistance, 24 lines homozygous for each QTL were selected from 2,818 progeny of a BC

backcrossed population, and characterized for disease phenotypes. The panicle blast resistance of the lines harboring
qPbm11
was very similar to the resistant donor parental cultivar Miyazakimochi, whereas the contribution of
qPbm9
to the resistance was small. Genotyping of the BC
2
F

individuals highlighted the overlap between the
qPbm11
region and a locus of the panicle blast resistance gene,
Pb1
. Reverse transcriptase PCR analysis revealed that the
Pb1
transcript was absent in the panicles of Miyazakimochi, demonstrating that
qPbm11
is a novel genetic component of panicle blast resistance.
Conclusions
This study revealed that Miyazakimochi harbors a novel panicle blast resistance controlled mainly by the major QTL
qPbm11. qPbm11
is distinct from
Pb1
and could be a genetic source for breeding panicle blast resistance, and will improve understanding of the molecular basis of host resistance to panicle blast. |
