Please accept my apologies if I am in error, but it appeared as though the content you added to Somaclonal variation was based too closely on "Methods in plant tissue culture (second edition 2002) by U. Kumar". Contributors may use copyrighted publications as a source of information, but not as a source of sentences or phrases. You are welcome to discuss this matter or anything else at my talk page.
