Plants are transformed with constructs encoding 5 either an active Anabaena sp. sucrose synthase gene or a soybean nodule sucrose synthase gene, which leads to increased cellulose content when over-expressed under the control of a cambium/xylem preferred promoter. Plant transformants harboring an Anabaena sp. or a soybean nodule sucrose synthase gene demonstrated increased content of cellulose, a train that is thought to improve woody trees for cellulose 10 extraction during pulping and papermaking.FIG. 6 Cellulose Content of SUSYcu TO Transgenic Plants 0 & A., Control Transgenic Events 6/7
