Expressed sequence tags from Madagascar periwinkle (Catharanthus roseus) [PDF]
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 ...

Reduction of Phytophthora Blight of Madagascar Periwinkle in Florida by Soil Solarization in Autumn [PDF]
Three field experiments were conducted in southwest and west-central Florida in 1993 through 1995 to evaluate the effectiveness of soil solarization during autumn in reducing Phytophthora blight of Madagascar periwinkle (Catharanthus roseus) caused by Phytophthora nicotianae.

Silencing of CrNPR1 and CrNPR3 Alters Plant Susceptibility to Periwinkle Leaf Yellowing Phytoplasma
Phytoplasmas are prokaryotic plant pathogens that cause considerable loss in many economically important crops, and an increasing number of phytoplasma diseases are being reported on new hosts. Knowledge of plant defense mechanisms against such pathogens

Crystal structure of akuammicine, an indole alkaloid from Catharanthus roseus
The title compound, C20H22N2O2, an alkaloid isolated from the Madagascar periwinkle, crystallizes in P1 with two independent but closely similar molecules in the unit cell. The molecules are linked into pairs by two N—H...O=C hydrogen bonds. The absolute
