Abstract
Abstract Erythrosine B (EB), a specific inhibitor of calcium (Ca2+)‐dependent Mg2+‐ATPase in plasma membranes, was evaluated for influence on 45Ca2+ uptake by 1 cm root tips from seedlings of four sorghum [Sorghum bicolor (L.) Moench cv Funk G522DR, GP‐1O, SC574, SC283] cultivars. Erythrosine B (0.01 μM) inhibited 45Ca2+ uptake 33% in SC574 and GP‐10; but higher concentrations (1 μM) were required to produce equivalent 45Ca2+ uptake inhibitions in SC283 and Funk G522DR.
