In Vitro Response

In vitro response of four local Indica rice cultivars viz. Sadamota, Kachamota, Moulata and Dudhkalam was evaluated. The aim of this study is to develop an efficient protocol for callus induction, plant regeneration and to observe the effect of gamma radiation on plant regeneration for creating possible genetic variability. In Different concentration of 2,4-D and growth regulators were supplemented with MS medium (Murashige and Skoog’s) to observe their callus induction frequency using mature embryo as explant. Among the cutivars, the highest primary callus (92.55%) as well as embryogenic callus induction (56.26%) was showed in sadamota at 3.0 mgl-1 2,4-D and 10 mgl-1 kinetin under dark condition. Twenty one days old embryogenic calli were exposed to 0, 2, 4 and 6 Gy of gamma rays and transferred to regeneration medium. Both callus growth and regeneration capacity were found to be decreased with increasing level of exposure to gamma rays. The doses of 4 Gy of gamma radiation were found to be the 50% inhibition dose for callus growth and plant regeneration in sadamota and kachamota, repectively whereas the 50% inhibition dose for moulata and dudhkalam at 2 Gy. This results indicate that sentivity of gamma radiation on rice callus depends on genotype of a genus.

An efficient protocol was developed for in vitro morphogenic ability along with plantlet regeneration of two Bangladeshi indica rice varieties (BR24 and BR26) via somatic embryogenesis by applying 50 mM NaCl stress in callus induction and suspension initiation media. Osmotic stress was induced by NaCl (50, 100, 150, 200 and 250 mM) on the cell growth in suspension maintenance media. In viability test stress adapted cells showed 85 - 95% viability up to 200 mM NaCl compared with stress shocked (MS1-50) and control (MS1-0) treatments. Higher stress adapted cells showed growth retardation and the induction of plasmolysis. For both genotypes somatic embryos were obtained in both MS based liquid and semisolid media with or without 50 and 100 mM NaCl. Cell suspension-derived micro-calli were partially desiccated (6 - 12 hr) and subsequently maintained in MS1 callus induction media supplemented with proline (12 mM), ABA (2 mg/l) and 0.6% phytagel in the presence or absence of 50 and 100 mM NaCl. Subsequently, desiccated somatic embryos were transferred in MS based regeneration media with or without 50 and 100 mM NaCl. Proline mediated callus was found to be more effective in embryo differentiation than ABA. Partial desiccation dramatically enhanced callus growth and partially increased regeneration percentage. BR24 showed a better regeneration response producing plantlets in presence of proline in control media while BR26 restored regeneration potential in the presence of ABA and 100 mM NaCl. Plantlets regenerated from salt stressed callus cultures were then grown in compost in a glasshouse and produced normal, fertile plants.  Key words: Indica rice, Cell suspension, Morphogenic, Regeneration D.O.I. 10.3329/ptcb.v19i2.5436 Plant Tissue Cult. & Biotech. 19(2): 185-197, 2009 (December)

Indica rice varieties are recalcitrant to culture and hence the culture media should be supplemented with additional nutrients to provide energy and osmotic potential for best in vitro response. Combinations of plant growth regulators have profound influence on callus induction and regeneration potential of the selected genotypes. In addition, concentration and choice of gelling agents also have their effect on regeneration of indica rice varieties. Impact of L-Proline, and Casein Hydrolysate on tissue culture response of selected indica rice varieties is discussed and the best choice of gelling agent and their in vitro response is elucidated.

The study was conducted at Biotechnology Division of Bangladesh Rice Research Institute (BRRI) to investigate the effects of plant growing medium and plant growth regulator (PGR) for the callus induction and high frequency plantlets regeneration of indica rice. Ten indica rice varieties viz. BR5, BR11, BRRI dhan28, BRRI dhan29, BRRI dhan33, BRRI dhan41, BRRI dhan47, BRRI dhan48, BRRI dhan49 and BRRI dhan50 were cultured on MS, N6 and LS media. The MS medium was found better for callus induction as compared to N6 and LS media. Among the tested varieties BRRI dhan48 induced the highest percent and best quality callus. Interaction effects of BRRI dhan48 to MS medium yielded 71.55% callus induction. The regeneration efficiency of BRRI dhan48 was tested on MS medium supplemented with different combination of NAA plus BAP and NAA plus kinetin. MS medium supplemented with 2.0 mg L-1 NAA and 2.0 mg L-1 Kn was found the best in respect of percent regenerated (76.67%) plantlet as well as for the growth of plantlets in vitro.Bangladesh Rice j. 2016, 20(2): 81-87

Though regeneration system in rice has been very well established compare to other crop plants, the fact remains that, most of the indica rice varieties are still recalcitrant for regeneration and genetic transformation. Therefore, refinement of tissue culture protocol for generation of embryogenic calli and regeneration of the fertile plants from a single cell should be a pre requisite event for development of transgenic plants. Here, in this study we reported high frequency robust regeneration protocols for a popular Indica cultivar Swarna.Mature seeds were used as initial material as explants. Highest callus induction % was observed in MSCIMP medium containing 2.0 mg-1 2,4, D + 0.5 mg-1 Kn as phytohormonal combinations. In addition, maximum regeneration was observed in 2.0 mg-l KN + 0.5 mg-l NAA. Regenerated plants were shifted to rooting medium followed by polyhouse for hardening. The callus induction and regeneration reported in this study were well suited for transformation agronomical important genes or functional genomics studies.

Significant variations were observed among six elite Bangladeshi Indica rice cultivars tested in relation to total callus induction frequency (p = 0.017), embryogenic callus formation frequency (p = 0.001) and subsequent plant regeneration responses (p = 0.005). In all the cases, embryogenic callus formation frequency was much more less than the total callus (embryogenic + non-embryonegic) formation frequency. The embryogenic calli derived from mature seed embryos produced green plants, successfully established in soil and produced fertile seeds.Key words: Indica rice, Callus induction, Plant regeneration, Genotypic variationsDOI = 10.3329/ptcb.v17i1.1122Plant Tissue Cult. & Biotech. 17(1): 65-70, 2007 (June)
