Title
Multifunctional proline rich proteins and their role in regulating cellular proline content in plants under stress
Abstract
© 2019, Institute of Experimental Botany, ASCR. All rights reserved. Proline rich proteins (PRPs), earlier famous as animal salivary proteins, have now been proven as indispensable plant proteins. They are highly rich in proline amino acid residues at the N-terminus whereas a characteristic eight cysteine motif is located at the C-terminus. The PRPs support a number of developmental processes from germination to plant death. Under normal environmental conditions, PRP genes express customarily in different plant parts depending on the specific function to be carried out. During abiotic stresses, PRP genes exhibit an uneven pattern of transcriptional regulation depending on the time and intensity of stress. Transgenic plants overexpressing PRP genes show an enhanced tolerance to abiotic stresses. This review focuses on contemporary functions of PRPs during stresses and proposes that PRPs are involved in the regulation of free cellular proline content during stress in a well synchronized manner.
