Viagra interferes with sexual reproduction of plants There was a research on whether plants are dependent on nitrogen monoxide or nitric oxide (NO) for successful reproduction.

Ana Margarida Prado from Instituto Gulbenkian de Ciencia, Portugal has found out that pollen tubes are dependent on nitric oxide to direct them to the right place in order to fertilize the plant. If there is a drug like buy Viagra the sensitivity of the plant to NO enlarges thus influencing the bending of a pollen tube.

On July 14th, in Barcelona, Spain, Margarida Prado will present this work on redirection of pollen tube in the Society for Experimental Biology Annual Main Meeting.

Lilium longiflorum or Easter lily pollen tubes was subjected by Prado to an artificial NO source and after that, she removed the nitric oxide using a scavenger of NO, found out that the pollen tubes reorientation was blocked buy viagra online.

Prado explains that in physiology of animals, nitric oxide is involved in the intercellular communication and concerning plants it could work as a guidance signal for the pollen tubes to an unfertilized ovule.

She adds that this can act as a safeguard mechanism in order to block polyspermy that is dual fertilization.

The research of Prado was the first to show a NO role in biology of pollen tube, and farther research is going to be performed in order to confirm a NO function in a plant like that in an animal buy cialis online.
