Abstract Background Anarrhinum pubescens Fresen. (Plantaginaceae) is a rare plant, endemic to the Saint Catherine area, of South Sinai, Egypt. Earlier studies have reported the isolation of cytotoxic and anti-cholinesterase iridoid glucosides from the aerial parts of the plant. The present study aimed to investigate the chemical profiling of the wild plant shoots as well as establish efficient protocols for in vitro plant regeneration and proliferation with further assessment of the genetic stability of the in vitro regenerated plants. Results Twenty-seven metabolites have been identified in wild plant shoots using the Nuclear Magnetic Resonance (NMR) spectroscopy. The metabolites include alkaloids, amino acids, carbohydrates, organic acids, vitamins, and a phenol. In vitro propagation of the plant was carried out through nodal cutting-micropropagation and leaf segment-direct organogenesis. The best results were obtained when nodal cutting explants were cultured on Murashige and Skoog medium with Gamborg B5 vitamins supplemented with 6-benzylaminopurine (BAP) (1.0 mg/L) and naphthaleneacetic acid (NAA) (0.05 mg/L), which gave a shoot formation capacity of 100% and a mean number of shoots of 27.67 ± 1.4/explant. These shoots were successfully rooted and transferred to the greenhouse and the survival rate was 75%. Genetic fidelity evaluation of the micropropagated clones was carried out using random amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) molecular markers. Jaccard’s similarity coefficient indicated a similarity as high as 98% and 95% from RAPD and ISSR markers, respectively. Conclusions This study provides the chemical profiling of the aerial part of Anarrhinum pubescens. Moreover, in vitro regeneration through different tissue culture techniques has been established for mass propagation of the plant, and the genetic fidelity of the in vitro regenerated plants was confirmed as well. Our work on the in vitro propagation of A. pubescens will be helpful in ex situ conservation and identification of bioactive metabolites.

Polygonum Hydropiper

An efficient protocol for plant regeneration through multiple shoots induction from shoot tips of Polygonum hydropiper (L.) was established. The highest percentage (96.6) of multiple shoot induction and number of shoots (9.0) per culture were found on MS supplemented with 2.0 mg/l Kn. The induced shoots were excised and inoculated on to MS contains different concentrations of IBA or NAA for rooting. The highest percentage (90.0) of root induction and the highest number of roots per shoot (12.0) was found on MS having 1.0 mg/l IBA. Well rooted plantlets were acclimated properly and transplanted in the soil under natural condition, where cent per cent plantlets survived and grew successfully. Key words:  Polygonum hydropiper, Shoot tips, In vitro propagation D.O.I. 10.3329/ptcb.v20i1.5970 Plant Tissue Cult. & Biotech. 20(1): 73-79, 2010 (June)

Cucumis Melo L

A rapid and efficient protocol is outlined for in vitro propagation of muskmelon(Cucumis melo L.) Shoot tips, nodal segments and cotyledonary nodes from invitro grown seedlings were used as explants. The explants were inoculated on MS medium fortified with different combinations and concentrations of growthregulators viz., BAP, NAA, GA3 and IBA for multiple shoot regeneration.Effective result was found on MS medium supplemented with 2.0 mg/l BAP, inwhich 90% and 70% cultures induced multiple shoots from nodal segments andshoot tip explants, respectively. Whereas, 70% cultures of cotyledonary nodeswere found to induced shoots on MS medium with 1.5 mg/l BAP + 0.1 mg/l GA3. In vitro regenerated shoots were subcultured on half strength MS mediumsupplemented with different concentrations of IBA and NAA for successful rootinduction and the effective result (up to 70%) was found in medium with 1 mg/lIBA. Well rooted in vitro grown plantlets were acclimatized in sandy soil, whereas 70% plantlets survived

Aulosira Fertilissima

Hot extract of Aulosira fertilissima (cyanobacterium) added in different proportions to MS as a liquid culture media for the in vitro propagation of Bacopa monnieri (L.) Pennell. Maximum numbers of shoots were induced from axillary node in MS media (40 ml) + Aulosira extract (60 ml) and maximum shoot multiplication was observed when Kn (1.0 mg/l) was added in the shoot initiation media (mentioned above). Surprisingly rooting was also found to be best in the same combination of MS + cyanobacterial extract that was used for initiation and multiplication of shoots. On an average within a period of three subcultures (2 - 3 months) the nodal explants generated 400 shoots.  Rooted plantlets were successfully transferred to the field, after acclimation in the net house.   Key words: Baccopa monnieri, Cyanobacterial extract, Regeneration, Acclimation   D.O.I. 10.3329/ptcb.v20i2.6917   Plant Tissue Cult. & Biotech. 20(2): 225-231, 2010 (December)
