Summary

Treating cultures of Agrobacterium tumefaciens in liquid medium with capsicin in doses of 0.0025, 0.005 and 0.01 g, especially in the highest dose, greatly increases its tumor-inducing ability, causing intense tumor growth; no such growth is produced by an untreated culture. Under the same influence the bacterium also increases greatly its multiplication ability, and to a certain degree — its virulence, too.

Additional information

According to Thresh, capsicin means the raw oily alkaloidal substance extracted from the fruit of red peppers (Capsicum annuum L.), containing also the alkaloid with the same taste-capsicin; the latter term means the chemically pure alkaloid.
