Cloning and Characterization of One NBS-LRR like Resistance Gene Analog from Banana
摘要
Abstract
Degenerated PCR using primers targeted to NBS conserved motifs is a rapid and facile strategy for isolation of NBS sequences linked to disease resistance genes. This PCR-based approach was used isolate and characterize a NBS-LRR like resistance gene analog (GenBank Accession No. AY739270) from banana, which was named B-NBS.After the multialignment with NBS domains of other six known plant R proteins, four NBS conserved domains were genetic distance of B-NBS with NBS domains of other six known plant R proteins was found smaller than 21.7. This showed that B-NBS was an NBS-LRR like resistance gene analog (RGA). This will lay a RGAs resources foundation for cloning banana R-gene and studying its disease resistance mechanism.关键词
