Abstract

Plant phytosterol compositions are modulated in transgenic plants to confer resistance to insects, nematodes, fungi, and / or other environmental stresses, and / or to improve the nutritional value of the plants. Recombinant DNA molecules of the invention encode RNA or protein sequences capable of altering plant sterol profiles by affecting the expression or activity of sterol biosynthetic enzymes. The DNA molecules are transformed into plant cells and plants having altered sterol compositions are regenerated therefrom.

Description

[0001] The present invention relates broadly to plant genetic engineering. More specifically, it relates to manipulating the level and / or activity of endogenous phytosterol components as a strategy to minimize crop damage from plant insects or other pests and / or to enhance plant nutrition value. Background of the invention

[0002] Harsh environmental factors such as drought, severe cold, weeds and crop-eating organisms can cause harm to agricultural production. Traditional methods of killing weeds and parasites rely almost entirely on chemical herbicides, pesticides and fungicides. However, the widespread use of these agricultural chemicals has led to the development of resistance. In fact, insects have been reported to be resistant to most major classes of insecticides, including organophosphates, chlorinated hydrocarbons, and carbamates.

[0003] Sterols comprise a class of essentially natural compounds that are required to some extent by all eukar...
