In Vitro Shoot Regeneration

Efforts have been made to establish a protocol for direct multiple shoot regeneration from both in vitro grown seedlings and mature plants of Citrus macroptera. Both nodal and shoot tip explants taken from in vitro grown seedlings were cultured in MS supplemented with different concentrations of BAP and Kn either singly or in combinations. Both these explants are capable to regenerate and produce in vitro multiple shoots. Maximum number of shoots were obtained from nodal explants in MS supplemented with 1.0 mg/l BAP. BAP alone was found superior to Kn. On the other hand, only nodal explants from mature plants were used and 1.0 mg/1 BAP was also found best suitable for shoot induction and multiplication. Ex vitro rooting in pot soil (mixed with biogas slurry derived from cow-dung) was most successful compared to in vitro rooting in half strength of MS supplemented with different concentrations of NAA and IBA. Key words: In vitro, Shoot regeneration, Citrus macroptera D.O.I. 10.3329/ptcb.v18i1.3246 Plant Tissue Cult. & Biotech. 18(1): 17-24, 2008 (June)

Multiple Shoot Regeneration

A simple, repeatable and efficient protocol for direct multiple shoot regeneration from internodal explants has been defined in peppermint ( Mentha x piperita var. Indus). In vitro regenerated shoots of peppermint were excised into 4 to 8 mm long internodes and cultured on Murashige and Skoog's medium supplemented with different cytokinins. In the hormonal assay, 3.0 mg L-l zeatin or 6-isopentenyl adenine independently supplemented to half strength MS medium exhibited multiple shoot regeneration, while thiaduzorn (0.1-3.0 mg L−1) showed no morphogenetic effect. A maximum of 85% in vitro cultured explants showed multiple shoot formation with an average of 7 shoots per explant on MS medium supplemented with zeatin. Multiple shoots were initiated within three weeks of cultivation. Internodes with regenerated multiple shoots were transferred to half - strength MS medium without supplementing with any plant growth hormone for shoot elongation and rhizogenesis. Rooted plants acclimatized and grew to maturity under glasshouse conditions. The plantlets developed were phenotypically identical to the parent plant and exhibited 96 % survival.

Investigation on in vitro multiple shoot regeneration in Bacopa monnieri (L.) Penn. using leaf and nodal explants was carried out on MS containing various concentrations and combinations of BAP, Kn, NAA and 2,4-D. Of the two explants, leaf showed the best response towards shoot regeneration and subsequent plant development on MS with 1.0 mg/l BAP and 0.25 mg/l Kn. In this combination, the mean number of shoots/explant was 10.6 ± 0.11 in leaf and 9.6 ± 0.29 in nodal explants. Maximum shoot length was recorded as 12.6 ± 0.21 and 11.20 ± 0.30 from leaf and nodal explants after six weeks of culture, respectively. Half strength of MS supplemented with 0.25 mg/l IBA was found to be the best medium for root formation. The in vitro regenerated plantlets were successfully transplanted in soil after acclimatization. Plant Tissue Cult. & Biotech. 30(1): 57-63, 2020 (June)

An efficient in vitro regeneration protocol was developed in medicinal aroid, Ghetkachu (Typhonium trilobatum Schott) using field grown corm bud explant. Highest percentage (75 %) of direct multiple shoot regeneration obtained in MS media supplemented with 5.0 mgL-1BAP + 1.5mg L-1NAA. Callus formation occur (80 %) in MS media containing 0.5mgL-1BAP + 2.0mgL-1NAA. The appearance of calli was white, creamy white light green in colour and the texture of calli were soft, friable and semi hard and compact. Shoot regeneration (85 %) obtained from calli in MS medium having 5.0mgL-1BAP +1.0mgL-1NAA. The regenerated plantlets were successfully acclimatized with loamy fertile soil and survived cent percentage in natural condition.   DOI: http://dx.doi.org/10.3329/bjsir.v47i2.11454   Bangladesh J.

Multiple Shoot Regeneration

Healthy multiple shoot regeneration was observed from petiole-attached cotyledon (PC) explants of CVL-1 on MS containing 0.2 mg/l BAP and 1.0 mg/l IAA. On the other hand, the best response for multiple shoot regeneration in CVE-3 was obtained when the same explants were cultured on MS with 2.5 mg/l BAP and 0.5 mg/l NAA. However, the same explant of D-154 was found to show less responsive compared to other two varieties to produce multiple shoots. Cotyledonary nodal explants of all the three varieties were found to produce maximum number of multiple shoots on MS supplemented with 0.2 mg/l BAP and 1.0 mg/l IAA. Best root induction was observed at the base of the in vitro regenerated shoots on half the strength of MS supplemented with 0.3 mg/l IBA. The in vitro grown plantlets were successfully transplanted into soil. They grew up to maturity, flowered and fruited like the control plants.Key words: Regeneration, White jute, Corchorus capsularisDOI = 10.3329/ptcb.v17i1.1116Plant Tissue Cult. & Biotech. 17(1): 11-18, 2007 (June)

Multiple Shoot Regeneration

MS with different concentrations and combinations of hormones were used for in vitro multiple shoot regeneration in two varieties of Brassica juncea, namely, BARI Sarisha-11 and BARI Sarisha-16 and one variety of Brassica campestris, Tori-7. The highest percentage of responsive explants towards the regeneration of shoots was obtained on MS with 2.0 mg/l BAP, 0.2 mg/l NAA and 0.5 mg/l Kn in case of BARI Sarisha-11 and BARI Sarisha-16. For Tori-7, 3.0 mg/l BAP and 0.2 mg/l NAA was best for obtaining maximum number of shoots per explant. Among three varieties, BARI Sarisha-11 showed best response in terms of shoot regeneration as well as number of shoot per explant. Days required for induction of shoots was also recorded to be lowest in BARI Sarisha-11. Best root induction in BARI Sarisha-11 and BARI Sarisha-16 was achieved on hormone free MS. After proper hardening the in vitro regenerated plantlets were successfully transplanted into soil. Interestingly some of the in vitro regenerated shoots produced in vitro flowers on regeneration media as well as hormone free MS.
