pubmed:abstractText |
Soybean cell suspension cultures have been used to investigate the role of the elevation of the cytosolic Ca(2+) concentration in beta-glucan elicitors-induced defence responses, such as H(2)O(2) and phytoalexin production. The intracellular Ca(2+) concentration was monitored in transgenic cells expressing the Ca(2+)-sensing aequorin. Two lines of evidence showed that a transient increase of the cytosolic Ca(2+) concentration is not necessarily involved in the induction of H(2)O(2) generation: (i) a Bradyrhizobium japonicum cyclic beta-glucan induced the H(2)O(2) burst without increasing the cytosolic Ca(2+) concentration; (ii) two ion channel blockers (anthracene-9-carboxylate, A9C; 5-nitro-2-(3-phenylpropylamino)-benzoate, NPPB) could not prevent a Phytophthora soja beta-glucan elicitor-induced H(2)O(2) synthesis but did prevent a cytosolic Ca(2+) concentration increase. Moreover, A9C and NPPB inhibited P. sojae beta-glucan-elicited defence-related gene inductions as well as the inducible accumulation of phytoalexins, suggesting that the P. sojae beta-glucan-induced transient cytosolic Ca(2+) increase is not necessary for the elicitation of H(2)O(2) production but is very likely required for phytoalexin synthesis.
