Transgenic strategies for genetic improvement of Basmati rice.

Abstract

Transgenic approach offers an attractive alternative to conventional techniques for the genetic improvement of Basmati rice because they enable the introduction of one or more genes into a leading cultivar without affecting its genetic background. During the last ten years, a rapid progress has been made towards the development of transformation methods in rice. Several transformation methods including Agrobacterium, biolistic, and DNA uptake by protoplasts, have been employed to produce transgenic rice. An array of useful genes is now available and many of these have already been transferred in rice to improve the resistance against biotic and abiotic stresses. In Basmati rice, a beginning has already been made regarding the development of tissue culture protocols, transformation methods and production of useful transgenic plants. The application and future prospects of transformation technology to engineer the resistance against insect pests (stem borer, leaf folder, brown plant hopper, gall midge), fungal diseases (blast, bakanae/foot, rot), bacterial diseases (bacterial leaf blight, sheath blight), abiotic stresses (salinity and drought) and improved nutritional quality (accumulation of provitamin A and essential amino acids in endosperm) in Basmati rice, have been addressed.
