The Madagascar periwinkle (Catharanthus roseus) is well known to produce the chemotherapeutic anticancer agents, vinblastine and vincristine. In spite of its importance, no expressed sequence tag (EST) analysis of this plant has been reported. Two cDNA libraries were generated from RNA isolated from the base part of young leaves and from root tips to select 9,824 random clones for unidirectional sequencing, to yield 3,327 related sequences and 1,696 singletons by cluster analysis. Putative functions of 3,663 clones were assigned, from 5,023 non-redundant ESTs to establish a resource for transcriptome analysis and gene discovery in this medicinal plant.
