Glyphosate-tolerance in Catharanthus roseus

Plant Science, 1988
Abstract Cultured cells of Catharanthus roseus were selected by a stepwise procedure for tolerance to the herbicide glyphosate. The selected cells were found to contain levels of extractable 5-enolpyruvylshikimic acid-3-phosphate (EPSP) synthase activity significantly greater than those found in non-selected cells.

Alkaloid metabolism in wounded Catharanthus roseus seedlings

Plant Physiology and Biochemistry, 2004
The effect of mechanical wounding on alkaloid metabolism was analyzed in Catharanthus roseus seedlings. Wounding induced an increase in ajmalicine accumulation, whereas catharanthine remained unaffected. A positive dual effect on vindoline was noticed.

Proteome analysis of the medicinal plant Catharanthus roseus

Planta, 2005
A proteomic approach is undertaken aiming at the identification of novel proteins involved in the alkaloid biosynthesis of Catharanthus roseus. The C. roseus cell suspension culture A11 accumulates the terpenoid indole alkaloids strictosidine, ajmalicine and vindolinine.

The proton-pumps at the plasmalemma of Catharanthus roseus cells

Biochimie, 1986
Cultured Catharanthus roseus cells exhibit transmembrane ferricyanide (FIC) reduction which is associated with a proton translocation and a decrease in the ATP content of the cells. The H+ efflux and the ATP consumption may be counteracted by vanadate, a specific inhibitor of the ATPase activity, and by Na2WO4 which prevents FIC reduction.

Biosynthesis of brassinosteroids in cultured cells of Catharanthus roseus

Phytochemistry, 2000
Precursor administration experiments with 2H-labeled 6-oxocampestanol, 6-deoxocastasterone and 6alpha-hydroxycastasterone in cultured cells of Catharanthus roseus were performed and the metabolites were analyzed by GC-MS. [2H6]Cathasterone was identified as a metabolite of [2H6]6-oxocampestanol, whereas [2H6]6alpha-hydroxycastasterone and [2H6 ...

การใช้โคลซิซีนชักนำให้เกิดโพลีพลอยด์ในแพงพวยฝรั่ง (Catharanthus roseus G.Don)

ในการชักนำแพงพวยฝรั่งสีขาวและสีชมพูให้เป็น polyploid ทำได้โดยหยดสารละลายโคลชิซีนที่มีความเข้มข้น 0.2 เปอร์เซ็นต์, 0.6 เปอร์เซ็นต์ และ 1.0 เปอร์เซ็นต์ ลงบนยอดต้นกล้าครั้งละหนึ่งหยด วันละ 3 ครั้ง ทุกความเข้มข้นหยดโคลชิซีนให้ต้นกล้า 6 ครั้ง, 12 ครั้ง และ 18 ครั้ง ตามลำดับ โคลชิซีนมีผลต่อการเจริญเติบโตของต้นกล้าและลักษณะภายนอกของต้น ใบ คือทำให้ต้นเต ...
