Abstract

A method was developed for the isolation of megabase-size DNA from Sorghum bicolor. Sorghum protoplasts were isolated from young leaf tissue, embedded in an agarose matrix as microbeads or plugs, followed by cell lysis and protein degradation. The DNA prepared by this method was larger than 1 Mb in size and readily digestible with restriction enzymes. The DNA was shown to be suitable for physical mapping, and was successfully used for the construction of BAC and YAC libraries.
