Effect of endochitinase and chitobiosidase and their encoding genes on plant growth and development

摘要

The present invention relates to enzymes with chitobiosidase and endochitinolytic activity and the genes encoding these enzymes. The chitinolytic enzymes of the invention can be applied to a plant or plant seed under conditions effective to promote plant growth, decrease plant size, and increase plant yield. Alternatively, transgenic plants or transgenic plant seeds transformed with a DNA molecule encoding a chitinolytic enzyme can be provided and the transgenic plants or plants resulting from the transgenic plant seeds are grown under conditions effective to promote plant growth, decrease plant size and increase plant yield.
