US Classification:

800278, 800298, 800305, 8003173, 8003174, 8003172, 800312, 8003202, 8003201, 8003203, 435183, 536 232, 4353201

Abstract:

Methods are provided for increasing plant growth rate, biomass and tolerance to stress by genetically engineering plants to contain and express a gene of the ascorbic acid synthesis-cell wall synthesis network (e.g. GlcUA reductase, GLOase or MIOX). Transgenic plants that are genetically engineered in such a manner are also provided.

Abstract:

Methods for increasing the vitamin C content of plants are provided by transforming the plants with genes encoding a novel vitamin C biosynthetic pathway. Vitamin C production is increased in the resulting transgenic plants, providing, for example, higher nutritional value and longer shelf-life of produce. Further, the leaves of air-cured varieties of tobacco transformed in this manner contain lower levels of highly carcinogenic tobacco specific nitrosamines (TSNAs).
