| biological activity of cyclopaldic acid, a major toxin of seiridium cupressi, its six derivatives, and iso-cyclopaldic acid. | cyclopaldic acid (ca), its six derivatives, and iso-cyclopaldic acid (isoca) were assayed for toxicity to cuttings of three species of cypress, as well as to mung bean, oat, and tomato explants. toxicity to host and non-host plants of ca derivatives having one or both of the aldehyde groups transformed was less than that of ca. shoot tissues of cupressus macrocarpa artificially infected by seiridium cupressi leached electrolytes more than those of c. sempervirens and c. arizonica. ca, isoca, and ... | 1995 | 7648024 |
| production of polyclonal antibodies for cyclopaldic acid, a major phytotoxic metabolite produced by the plant pathogen seiridium cupressi. | an antiserum against cyclopaldic acid (ca), a phytotoxic metabolite produced by seiridium cupressi, the fungal pathogen of a canker disease of cypress, was prepared by immunization of rabbits with a ca-bovine serum albumin conjugate (ca-bsa). antibodies recognizing ca were purified by affinity chromatography through an immunoadsorbent prepared by conjugating ca to lysine-sepharose 4b. the specificity of antibodies was assayed against ca and some of its derivatives by competitive indirect enzyme- ... | 1994 | 8087434 |
