Elongating Effect of the Peptide AEDL on the Root of Nicotiana tabacum under Salinity.

ABSTRACT: The overall survival of a plant depends on the development, growth, and functioning of the roots. Root development and growth are not only genetically programmed but are constantly influenced by environmental factors, with the roots adapting to such changes. The peptide AEDL (alanine-glutamine acid-asparagine acid-leucine) at a concentration of 10^-7 M had an elongating effect on the root cells of Nicotiana tabacum seedlings. The action of this peptide at such a low concentration is similar to that of peptide phytohormones. In the presence of 150 mM NaCl, a strong distortion in the development and architecture of the tobacco roots was observed. However, the combined presence of AEDL and NaCl resulted in normal root development. In the presence of AEDL, reactive oxygen spec
