title: A cDNA sequence coding for a glutamic acid-rich protein is differentially expressed in cassava storage roots.
abstract: We report the isolation and characterization of a cDNA sequence (Mec1) coding for a glutamic acid-rich protein (Pt2L4) from cassava storage roots. Comparative sequence analysis showed a high identity of Pt2L4 with cassava protein C54, which is expressed in vascular tissues of storage roots. Northern blot analysis showed that the Mec1 transcript expression pattern might be related to the maturation of the storage parenchyma cells.
