Abstract
Abstract—A steady decline of perennial bunch grasses in arid rangelands has resulted in losses of productivity and germplasm. Remediation is costly and rarely successful. Cryptic symbiotic fungi, structurally integrated with cells and organs of native plants cannot be separated from host plant tissue. However, they were successfully transferred from cell cultures of native plants to other native grasses and tomato. Fungi in recipient plants were heri-table and substantially enhanced vigor, biomass and reproductive potential. The transfer of novel fungal symbionts to other native or crop plants may offer an alternative method of improving plant performance without modifying native plant germplasm. Introduction_______________________ Native perennial bunch grasses have steadily declined in arid southwestern USA rangelands in the past century as a result of complex biotic and abiotic stress.
