The gesneriaceous perennial plant, Lysionotus serratus, has been used in traditional Chinese medicine. It also has a great development potential as an ornamental plant with its attractive foliage and beautiful flowers. An efficient propagation and regeneration system via direct shoot organogenesis from leaf explant was established in this study. High active cytokinin (6-benzyladenine (BA) or th...
Numerous plant hormones interact during plant growth and development. Elucidating the role of these various hormones on particular tissue types or developmental stages has been difficult with exogenous applications or constitutive expression studies. Therefore, we used tissue-specific promoters expressing CKX1 and gai, genes involved in oxidative cytokinin degradation and gibberellin (GA) signa...
Annona glabra is a tropical species that has significant agronomic potential in terms of furnishing fruits for in natura consumption and for the production of phyto-pharmaceuticals. In vitro cultivation has been considered the most promising form of propagation for this species, although large scale utilization of this technique is currently limited by high rates of leaf abscission, reduced rat...
Potato is a valuable plant as a source of nutrition and as an industrial product. The modification and breeding of potato plants are very difficult, or even impossible, via the conventional plant breeding programs. However, plant biotechnology and tissue culture are reliable methods which can produce plant material for gene transformation using Agrobacterium as a vector. In this study, one-, ...
In the recent years, increasing labour cost and shortage of being major constraints to follow manual harvesting in cotton staggered manner. Further, it is very expensive farmers would like increasingly opt for mechanical harvesting. this context, suggested that research should focus reduce cultivation substantially by promoting use synchronized maturity defoliants encourage agriculture, are use...
The percent study describes the in vitro responses of mature zygotic embryos of Boscia senegalensis to different concentrations (0.0-5.0 mg/L) of 6-benzyladnine (BA), Thidiazuron (TDZ), α-Naphthalene acetic acid (NAA), and 2, 4-Dichlorophenoxyacetic acid (2, 4-D) supplemented on Murashige and Skoog medium (MS). The plant growth regulators (PGRs) were considerably affected the morphogenetic resp...
Prospecting of local grapevine (Vitis vinifera L.) germplasm revealed that Tunisia possesses a rich patrimony which presents diversified organoleptic characteristics. However, viral diseases seriously affect all local grapevine cultivars which risk a complete extinction. Sanitation programs need to be established to preserve and exploit, as a gene pool, the Tunisian vineyards areas. The presenc...
A two-stage method for in vitro propagation of six Genista species from shoot tips was developed. Multiple microshoot cultures were obtained by growing the shoot tip explants on Schenk and Hildebrandt medium supplemented with 9.84 microM 6-(gamma,gamma-dimethylallylamino)-purine and 0.99 microM thidiazuron. The best shoot elongation was achieved on Schenk and Hildebrandt medium containing 4.92 ...
An effective and improved plant regeneration system was successfully developed using shoot tip explants taken from a two years old mature plant of Cassia angustifolia. The effect of different cytokinins, [6-benzyladenine (BA), Kinetin (Kin) and thidiazuron (TDZ)] at different concentrations (0.5-10 μM) were evaluated as augmented with Murashige and Skoog (MS 1962) medium. Among all the cytokini...
An efficient regeneration protocol was developed from shoot tip and nodal explants of Simarouba glauca DC, a promising biodiesel plant. Nodal explants appeared to have better regeneration capacity than shoot tip explants (40%) in the tested media. The highest regeneration frequency (90%) and shoot number (7.00 ± 1.00 shoots per explants) were obtained in nodal explants in Murashige and Skoog’s ...
