Proteoid Roots and Exudation of Proteases by Plant Roots

  • Chapter
  • First Online:
Secretions and Exudates in Biological Systems

Part of the book series: Signaling and Communication in Plants ((SIGCOMM,volume 12))

Abstract

Among the numerous strategies for improving P or N uptake by plants, development of proteoid roots and exudation of proteases can be found. Proteoid roots, which develop as a response to P deficiency during exudative burst secrete carboxylates and acid phosphatase, which improves P uptake. Proteoid root morphology and anatomy, factors that influence development and their role in plant nutrition, are described. In addition, this chapter summarizes our knowledge of the recently discovered phenomenon of protease secretion by intact plant roots, including their biochemical characterization and their potential role in the nitrogen nutrition of plants.
