Polyphenol oxidase (PPO, EC 1.14.18.1) was extracted from celery roots (Apium graveolens L.) with 0.1 M phosphate buffer, pH 7.0. The PPO was partially purified by (NH4)2SO4 and dialysis. Substrate specificity experiments were carried out with catechol, pyrogallol, L-DOPA, p-cresol, resorcinol, and

A multinucleocapsid nuclear polyhedrosis virus (MNPV) isolated from the celery looper, Anagrapha falcifera, has been proposed as a new virus based on differences in virulence and DNA fragment profiles between this isolate and the Autographa californica MNPV, the MNPV type species. In the present
