Role of RNA and Protein Synthesis in Abscission

PMCID: PMC1087148  PMID: 16657020

Abstract

The cell separation aspect of abscission is thought to involve the action of specific cell wall degrading enzymes. Enzymes represent synthesis which in turn is preceded by the synthesis of specific RNA molecules, and it follows that inhibition of either of these processes would also block abscission. Since abscission is a localized phenomenon usually involving 2 or 3 cell layers, RNA and protein synthesis should also be localized. Manipulations of plant material which either accelerate or retard abscission may be due to the regulation of RNA and protein synthesis. This paper is a review of literature concerned with these and related questions.
