Abstract

Based on the sequence of resistance gene analog FZ14 derived from Zizania latifolia(Griseb.), a pair of specific PCR primers FZ14P1/FZ14P2 was designed to isolate candidate disease resistance gene. The pooledPCR approach was adapted using the primer pairs to screen a genomic transformationcompetent artificial chromosome(TAC) library derived from Zizania latifolia. A positive TAC clone (ZR1) was obtained and confirmed by sequence analysis. The results indicated that ZR1 consisted of conserved motifs similar to Ploop (kinase 1a), kinase 2, kinase 3a and GLPL(Gly-Leu-Pro-Leu), indicating that it could be a portion of NBSLRR type of resistance gene. Using Agrobacterium tumafaciensmediated transformation of Nipponbare mature embryo, a total of 48 independent transgenic T0 plants were obtained. Among them, 36 plants were highly resistant to the virulent bacterial strain PXO71. The results indicated that ZR1 contains at least one bacterial blight resistance gene.
