Abstract:

A new method of one-step PCR was devised for detecting the first nucleotide in the splice donor site of Wx intron 1. compared to the regular PCR-AccⅠmethod, the method can produce the same result for detecting +1 nucleotide of Wx intron 1. The reliability of the new method was confirmed with 30 rice varieties. The new technique is more convenient and cheaper than the regular PCR-AccⅠmethod, and could be widely deploded in rice molecular marker assistant selection.
