Popis:	Root curvature response to unilaterally applied calcium (Ca2+) in agar was inhibited 81% by erythrosine B (EB) (10 nM) in sorghum [Sorghum bicolor (L.) Moench.] cv Funk G522DR, 70% in cv SC283, and 11% in cv SC574. EB (10 nM) is reported to totally inhibit Ca2+‐ATPase, while 10–50 μM EB is required to inhibit H+‐ATPase. Therefore, differences in relative concentrations of Ca2+‐ATPase and H+‐ATPase exist in the root plasma membranes (PM) of the three cultivars. Carbon dioxide (14CO2) production from glycerol‐tri‐(1‐14C)‐palmitate by wheat (Triticum aestivum L.) leaf rust (Puccinia recondita Rob. ex Desm.) urediospore germlings was inhibited 85% by EB (10 nM).
