Wirnt Rickthis system: .S, .M and .R. A polypeptide which governs the specificity of the system is determined by .S. The gene product of .M is the modification enzyme which also interacts with the product of the .R gene, the restriction endonuclease, in the cleavage process. In the above examples the phage gr

Wirnt Rickryotic cells or an . system for eukaryotic gene expression. Since such an approach is in its infancy, this chapter will serve simply to draw attention first to techniques for . mutagenesis, and second to some eukaryotic systems which are available to study the expression of cloned eukaryotic genes.

Wirnt Rickagriculture, and the unwitting use of them in pasture grasses has continued for many centuries. Endophytes have been recognized in species of the Pooideae (the cool-season grasses) for nearly a century (1), but the agricultural and ecological importance of these associations has been appreciated onl
