Toxic effects of Phaseollin (cas 13401-40-6) on plant cells

Add time:08/02/2019    Source:sciencedirect.com

Plant cells, from bean and tobacco suspension cultures and from pods and hypocotyls of bean, were rapidly killed following immersion in solutions containing 30 μg Phaseollin (cas 13401-40-6) per ml. These concentrations inhibited the respiration of bean cells within 2 min of treatment and also reduced the growth of bean suspension cultures during a 3 week incubation period. Thereafter, as a result of a few cells surviving, the rate of growth of the suspension cultures increased and significant amounts of dry matter were produced. The total amount of phaseollin present in the suspension cultures and its concentration in the growth medium decreased during the incubation period.These findings are discussed in relation to the similarities between the effects of phaseollin on plant and on fungal cells, and to their relevance to current concepts about the formation and rôle of phaseollin in infected plant tissues.
