9407177 McDonald This project is to advance and broaden our knowledge in the areas of plant cell biotechnology, ribosome inactivating proteins (RIPs), and plant cell bioprocess engineering. This project has three specific goals, which include: (1) characterization of the transformation of plant cell cultures by the plant pathogen Agrobacterium rhizogenes; (2) quantification of cell growth and RIP production in suspension culture; and (3) purification and characterization of proteins obtained from the cell cultures. RIPs are naturally occurring plant proteins thought to be ubiquitous in the plant kingdom, and are currently receiving considerable attention for their antiviral, antitumor and abortifacient properties. They are also being considered for their potential use in immunotoxin preparation and for their ability to confer resistance to plant pathogens. ***

9407177麦克唐纳这个项目是为了促进和拓宽我们在植物细胞生物技术、核糖体失活蛋白(RIPs)和植物细胞生物过程工程领域的知识。该项目有三个具体目标，其中包括：(1)植物病原菌发根农杆菌对植物细胞培养物的转化；(2)悬浮培养中细胞生长和RIP产生的量化；以及(3)从细胞培养物中获得的蛋白质的纯化和表征。RIPs是一种天然存在的植物蛋白，被认为广泛存在于植物界，目前因其抗病毒、抗肿瘤和抗流产特性而受到相当大的关注。人们还考虑它们在免疫毒素制备中的潜在用途，以及它们对植物病原体的抗性。***
