The effect of calcium and calmodulin modulators, viz., ethylene glycol bis (beta-amino ethyl ether)-N,N,N',N'-tetraacetic acid (EGTA), a calcium chelator; verapamil, a plasma membrane Ca2+ channel blocker; ruthenium red, an organelle Ca2+ channel blocker; and chlorpromazine, a calmodulin antagonist; on the development of Erysiphe pisi was studied by floating the inoculated leaves on the respective solutions of chemicals. All the modulators affected the development of E. pisi by inhibiting the colony diameter, number of secondary branches, number of hyphal cells per colony and number of haustoria. The calmodulin antagonist was more effective in reducing E. pisi development. The results suggest the possible involvement of calcium and calmodulin in the development of E. pisi on pea leaves.
通过将接种的叶片漂浮在相应的化学物质溶液上,研究了钙和钙调蛋白调节剂,即乙二醇双(β-氨基乙醚)-N,N,N',N'-四乙酸(EGTA,一种钙螯合剂)、维拉帕米(一种质膜Ca2+通道阻滞剂)、钌红(一种细胞器Ca2+通道阻滞剂)和氯丙嗪(一种钙调蛋白拮抗剂)对豌豆白粉菌发育的影响。所有调节剂均通过抑制菌落直径、二级分支数量、每个菌落的菌丝细胞数量和吸器数量来影响豌豆白粉菌的发育。钙调蛋白拮抗剂在减少豌豆白粉菌发育方面更有效。结果表明,钙和钙调蛋白可能参与了豌豆白粉菌在豌豆叶片上的发育过程。
