Abstract
This study was carried out at Genetic Engineering and Biotechnology Research Institute (GEBRI) ,Sadat City, Minofia University during the
period from 2007-2011 .
Nepeta septemcrenata Benth. is a rare endemic Egyptian plant with a
restricted habitat, reportedly found only in three separated localities in Saint
Katherine protectorate. Efforts to preserve this species should be carried out
to prevent its extinction and ensure its survival, and to take advantage of its
valuable biotechnological potential. Measures to develop micropropagation
protocols for this endangered shrub with high field survival are essential.
Plant tissue culture is considered, nowadays, as a unique and valuable
tool for growing plant cell, tissue and organ culture and as a production
system with secondary products available when and where required.
This study aimed to utilize plant tissue culture as a source of
pharmaceutical compounds, instead of import from abroad especially after
the application of General Agreement on Tariffs(GAT) .
