Effect of Exogenous D-Alanine on D-Alanyl-D-alanine Content in Leaf Blades ofOryza australiensisDomin

摘要

In seedlings ofOryza australiensisDomin (W0008), most of the D-alanyl-D-alanine was distributed in the leaf blades. In excised leaf blades of W0008, exogenous D-alanine was incorporated into D-alanyl-D-alanine irrespective of the light condition as in Sasanishiki. With cultivation in D-alanine medium for several days, the D-alanyl-D-alanine content in W0008 leaf blades was found to increase, but no other D-alanine-containing dipeptides such as D-alanylglycine or D-alanyl-L-alanine were detected
