Department of Plant Pathology, University of Hawaii Maui Agricultural Research Center, P.O. Anton. Transgenic approaches also facilitate disease resistance in pineapple by transforming polyphenol oxidase (PPO) or chitinases. Do not eat have a process that is all cone Pass. Both G. oxydans strains 303D and 180 required biotin, nicotinic acid, and pantothenic acid for growth; E. herbicola 189 required only nicotinic acid; however, A. aceti 295 was able to grow without any added supplements in glucose mineral salts medium. Transgenic expression of PPO gene displayed increased resistance for blackheart, and transgenic plants with chitinases expressed enhanced resistance against fungal pathogen.
