Growth requirements ofCuscuta reflexa

Studies underin vitro conditions withCuscuta stem tips have revealed that the parasite depends on the host for the supply of all essential requirements for its growth. The vestigial photosynthetic apparatus inCuscuta cannot meet its total requirements. Thus for supply of energy it depends primarily on the host. Inorganic nutrients seem to be of secondary importance and perhaps help to some extent in its independent metabolic pool. Carbohydrates, particularly sugars, are presumably tapped by the parasite from the translocating channels of the host and further utilised for its own growth. Besides sugars, which form the carbon and energy source, amino acids and growth substances are also found to be utilised. The mechanism of carbohydrate utilization inCuscuta has been postulated.
