dc.description.abstract | Efficient protocols, safe from somaclonal variation, were developed for
regeneration of Iris sibirica plants via organogenesis and somatic
embryogenesis from leaf-base explants cultivated on Murashige and Skoog
media supplemented with thidiazuron (TDZ, 1.0 mg/l) or
2,4-dichlorophenoxyacetic acid (2,4-D, 1.0 mg/l). The morphogenic
response and callus formation efficiency differed significantly between
2,4-D (80.9\%) and TDZ (67\%) morphogenesis induction treatments. TDZ
induced only organogenic calli, while calli obtained with 2,4-D were
composed of three types differing in color and consistency: white,
friable - embryogenic calli (4.5\%, 3.8 mg/explant), green, compact -
organogenic calli (12.4\%, 48.4 mg/explants) and yellow -
non-regenerative calli (773\%, 254.4 mg/explant). The cultivation of
embryogenic calli on medium with 2,4-0 and Kinetin resulted in further
development of somatic embryos (54 embryos/g of calli) which germinated
with a frequency of 62\% after being transferred to a medium without
plant growth regulators. Stable shoot cultures were established by
transferring organogenic calli with shoot primordia to media with 0.1
mg/l alpha-naphthaleneacetic acid (NAA) and 1.0 mg/l 6-benzylaminopurine
(BA), while further cultivation on media of the same composition (TDZ or
2,4-D) resulted in the reduced growth and rhizogenesis, respectively.
The TDZ induction treatment resulted in higher number of shoots per
explant (7.9) than the 2,4-0 treatment (43). After successful rooting
and ex vitro acclimatization, plants were grown in the field and
flowered to seed production. Flow cytometry, chromosome counting and
random amplification of polymorphic DNA (RAPD) analysis indicated no
evidence of genetic variation in plants regenerated via somatic
embryogenesis or organogenesis. The results suggest that established
protocols are safe for use in genetic transformation procedures or
large-scale production of true-to-type I. sibirica plants. (C) 2014
