Inheritance and expression of transgenes through anther culture of transgenic hot pepper

Z Naturforsch C J Biosci. 2007 Sep-Oct;62(9-10):743-6. doi: 10.1515/znc-2007-9-1018.

Abstract

Anther cultures have been developed from transgenic donor peppers carrying HPT/J1-1. Eight out of sixteen plants produced from an anther culture set pepper fruits. Southern blot analysis of donors revealed two independent plants with a single copy of the integrated transgene. PCR and RT-PCR results showed the inheritance of HPT/J1-1 and expression of J1-1 in A1. All A1 progeny derived from transgenic anthers had resistance to hygromycin. They grew normally and showed similar phenotypes to the wild-type. Therefore, the use of an anther culture system coupled with genetic transformation in breeding programs will greatly facilitate the genetic improvement of pepper plants.
