Eight genes which encode novel rice.beta.-glucanase isozymes Gns2-9 are discosed herein. The genes, the gene promoters, and nucleic acids encoding signal peptides, full-length proteins, and mature proteins, are useful in a variety of transgenic monocot plants, for example, in achieving increased plant resistance to fungal infection, improved growth characteristics, and high levels of expression of heterologous proteins in various tissues obtained from the plants. 1.
