In this study we report the development of effective in vitro systems for a medicinal plant Nigella damascena L. comprising:
(1) callus induction, (2) somatic embryogenesis in callus cultures with subsequent plant regeneration, and (3) isolation
and regeneration of callus-derived protoplasts. Callus development was achieved on 83–100% of hypocotyl and cotyledon
explants, whereby Murashige and Skoog medium (MS) supplemented with 3 mg L−
1 6-benzylaminopurine and 0.5 mg L−
1
α-naphthaleneacetic acid (NAA; BN medium) was more advantageous than MS with kinetin and NAA (KN medium). Histological
observations of calli revealed the presence of embryogenic zones from which somatic embryos developed on the
hormone-free medium. Plant regeneration was observed on 76–95% of calli. A high capacity to form somatic embryos and
regeneration was maintained in long-lasting cultures, i.e. even in 2 year old callus.
The obtained callus was also a good source tissue for protoplast isolation. By applying a mixture of cellulase and pectolyase,
the acceptable yield of viable protoplasts was achieved, especially from hypocotyl-derived callus maintained on BN medium.
Protoplasts embedded in an alginate matrix and cultured in modified Kao and Michayluk media re-constructed their cell
wall and re-entered mitotic divisions. About 30% of small cell aggregates formed microcalli, which, after the release from
alginate, proliferated continuously on KN and BN media, irrespective of the tissue variant used as the protoplast source.
Somatic embryo formation and plant regeneration were successful on hormone-free media. An effective plant regeneration
system of N. damascena protoplast cultures has been developed and is being reported for the first time
