Callus Induction and Direct Shoot Regeneration in Lepidium draba L. Explants
<em>Lepidium draba</em> through the production of anti-cancer and anti-microbial compound, sulforaphane, is considered a valuable medicinal plants.Therefore, optimization of in vitro tissue culture to facilitate genetic transformation and improvement of traits in this plant is important....
