Pathogenesis-Related Proteins in Plants

Hardback
A great deal of research has been focused on the isolation, characterization, and regulation of expression of pathogenesis-related proteins since the discovery that several of the PR-proteins had antimicrobial or insecticidal activity and can delay the progression of diseases caused by several pathogens belonging to diverse genera. This is an exciting period of research where constitutive (or inducible) expression of PR-proteins at effective levels could be used as a tool to enhance or stabilize yield in areas where pathogens and pests are endemic. Pathogenesis-Related Proteins in Plants analyzes the practical aspects of employing PR-proteins for plant protection, in a possible role as the first or last line of defense against pathogens and pests. In addition, PR-proteins expressed in apparently healthy tissues during normal plant growth such as seed development and flowering, may have additional unsuspected roles in morphogenesis or in symbiosis.
