Abstract
A protocol is presented for efficient transformation and regeneration of cotton. Embryogenic calli co-cultivated with Agrobacterium carrying cry1Ia5 gene were cultured under dehydration stress and antibiotic selection for 3–6 weeks to generate several transgenic embryos. An average of 75 globular embryo clusters were observed on selection plates and these embryos were cultured on multiplication medium followed by development of cotyledonary embryos on embryo maturation medium to obtain an average of 12 plants per Petri plate of co-cultivated callus. About 83% of these plants have been confirmed to be transgenic by Southern blot analysis. An efficiency of ten kanamycin-resistant plants per Petri plate of co-cultivated embryogenic callus was obtained. The simplicity of the procedure and the efficiency of the initial material allow transformation of any variety where a single regenerating embryogenic callus line can be obtained. In addition, multiple transformations can be performed either simultaneously or sequentially. The method is extremely simple, reliable, efficient, and much less laborious than any other existing method for cotton transformation.
