It is only a matter of time until a new disease develops which "So maintaining a biodiverse ecosystem, with many varieties of plants and animals, is like having a living insurance policy to help protect those crops and creatures we humans depend upon for our survival. If the specific genotype used isnt resistant to a particular invader, then the whole crop could be lost if the pathogen establishes itself in the environment. blight's penetration of the Corn Belt; just three Midwestern In other instances where disease attacks crops, there is no other source of resistance in the available population. Preservation of genetic diversity in ex-situ gene banks such as NCGRP is important for conservation of biological diversity and utilization of genetic resources for economic and environmental sustainability. of the advantages of hybrids containing all or a portion of plants its best blight resistant line at nearly thirty dollars per fifty-pound until the late 1970s, having been dismissed by the Iowa Supreme Court In St. Louis, NewLeaf Symbiotics is interested in bacteria of the genus Methylobacterium.
