Cyclic AMP Is Not Involved as a Second Messenger in the Response of Soybean to Infection by Phytophthora megasperma f. sp. glycinea
نویسنده
چکیده
Cyclic AMP, Radioimmunoassay, Phytoalexins, Glycine max, Phytophthora megasperma cAMP levels were monitored in soybean (Glycine max) infected with race 1 of Phytophthora megasperma f. sp. glycinea and in soybean cell suspension cultures treated with a glucan elicitor from P. megasperma. While cAMP could be readily detected in soybean hypocotyls using a radio immunoassay, no correlation was observed between infection and cAMP levels. No cAMP was detected in suspension cultured soybean cells. These results suggest that cAMP does not play a significant role in the plant’s response to fungal attack, or the response of suspension cultured cells to elicitor.

Phytophthora megasperma Drechs. f. sp. glycinea Kuan & Erwin (PMG) cell wall glucan has been extensively characterized as an elicitor of the pterocarpan phytoalexins, the glyceollins in soybean (Glycine max L.). Just recently, this glucan was shown to be a potent elicitor of conjugates of the isoflavones, daidzein and genistein as well. Here we report that PMG wall glucan also induces a rapid a...

Phenylalanine ammonia-lyase activity increased rapidly beginning 2 h after inoculation with Phytophthora megasperma (Drechs.) f.sp. glycinea (Hildeb.) Kuan & Erwin race 1 in unwounded hypocotyls of soybean cv. Harosoy 63 (resistant) but did not change significantly in cv. Harosoy (susceptible). Small increases in phenylalanine ammonia-lyase activity also were caused by wounding. Activity increa...

Etiolated hypocotyls of the resistant soybean (Glycine max [L.] Merr.) cultivar Harosoy 63 became susceptible to Phytophthora megasperma (Drechs.) f.sp. glycinea (Hildeb.) Kuan and Erwin race 1 after treatment with abscisic acid. Susceptibility was expressed by increases in lesion size and a major decrease in accumulation of the isoflavonoid phytoalexin, glyceollin. In untreated hypocotyls, act...
