Inductive Effects of Carbohydrates and Plant Regeneration via Anther Culture in Madagascar Periwinkle [PDF]
Advances in Zoology and Botany, 2021 Anther culture has emerged as an alternative for traditional plant breeding practices for homozygosity development, which in the case of medical plants resulting in increased yield of phytoconstituents. The response of anthers during culture is governed by the various constituents of the nutrient media.

Reduction of Phytophthora Blight of Madagascar Periwinkle in Florida by Soil Solarization in Autumn [PDF]
Plant Disease, 2000 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
Frontiers in Plant Science, 2019 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
Acta Crystallographica Section E: Crystallographic Communications, 2017 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
