in vitro techniques were developed for this important plant. This study
aimed at presenting an efficient plant regeneration approach from
leaves derived callus. For callus initiation and regeneration leaves of
20 days- aged axenic Arabidopsis seedlings were excised, cut and
cultured on both agar solidified B5 and Murashige and Skoog medium
(MS) supplemented with various types and concentrations of plant
growth regulators. The Results indicated that high regeneration
frequency of green plantlets was observed (more than 120 shoots) from
callus on B5 medium, eighty of these shoots were produced on B5
medium containing 5mgL-1BA and 0.9mgL-1IAA. The number of shoots
regenerated on MS medium was 21. Regenerated shoots were easily
and similarly rooted using full or 12 strength MS0 medium. The
rooted plantlets were adapted and successfully transplanted in field
conditions. In this study, an efficient protocol for regeneration of A.
thaliana was developed and optimal concentrations of phytohormones
were determined. | Keywords : | | Arabidopsis thaliana, Regeneration, Callus Cultures,
