Cotton plant event a26 5 and primer and method for use in detection thereof

摘要

Provided are bollworm resistant cotton transformation event A26 5 and a characteristic sequence thereof and a primer and method for use in detecting the transformation event. Transformation event A26 5 is located on the eighth set of chromosomes of a cotton plant and comprises a combination of an inserted exogenous DNA sequence and a cotton genome DNA sequence. Also provided is a primer for specificity detection of event A26 5 by utilizing the inserted exogenous DNA sequence and a flanking sequence of a junction area on the cotton genome. The method for detecting event A26 5 can be used as a means to provide use of the event for breeding with convenient tracking of the specific gene insertion event. The A26 5 gene insertion event can serve as a molecular marker for use in increasing breeding efficiency.
