文摘

The question, why Madagascar periwinkle Catharanthus roseus is a suitable host for uncultivable bacteria was addressed. The chemical composition of phloem and xylem sap of Madagascar periwinkle was achieved using GC-MS. Phloem sap was much richer in nutrients than xylem sap. Sixty-three and twenty compounds were detected in phloem and xylem sap, respectively. Saps contain organic compounds that are required for the growth of bacteria.
