Changes in RNA and protein contents, and protein profiles were studied in the rhizomes of turmeric (Curcuma longa L.) from the day of harvest to the commencement of sprouting. Protein and RNA contents increased gradually in the initial stages and rapidly in the final stages of storage period. SDS-PAGE analysis of storage proteins revealed synthesis of 56, 52 and 47 kDa proteins during the later stages of storage with concomitant disintegration of 23 and 18 kDa proteins.

Keywords: dormancy; SDS-PAGE; turmeric
Subjects: Curcuma longa; rhizome storage, proteins, RNA; turmeric rhizome, storage, proteins, RNA
