Besides the abundant nodulins like Lb, GS, uricase and sucrose synthetase, many other enzymes involved in nodule metabolism are induced during the course of nodule development (see Verma Nadler, 1984). However, owing to the relatively low abundance of these enzymes and their mRNAs in nodules, none of the cognate genes have been cloned and new cloning strategies need to be employed to isolate these relatively less abundantly expressed nodulin sequences.
