Line 19-51a was developed by recombinant DNA techniques to introduce a chimeric ALS gene, which encodes a sulfonylurea tolerant acetolactate synthase (ALS) enzyme.
The ALS enzyme produced in these transgenic cotton lines is a resistant form of the similar enzyme present in all plants, bacteria and fungi, and thereby confers resistance or tolerance to sulfonylurea herbicides.

The term “Recipient organism” refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas “Parental organisms” refers to those that were involved in cross breeding or cell fusion.
