Root parasites of the genus Orobanche are serious weeds in agriculture. An aseptic infection system of host roots using calli of three Orobanche species was developed for the study of host-parasite interaction. The response of calli to various hormonal combinations was studied, because a requirement for infection is the differentiation of root-like protrusions, which are capable of producing ha...

In this paper, we describe the transformation of regenerable maize tissues by electroporation. In many maize lines, immature zygotic embryos can give rise to embryogenic callus cultures from which plants can be regenerated. Immature zygotic embryos or embryogenic type I calli were wounded either enzymatically or mechanically and subsequently electroporated with a chimeric gene encoding neomycin...

Ten maize lines prevalently used by breeders in the maize program were screened for their ability to form type II callus. Mature seeds were used as explant for in vitro culturing. Inbred lines showed high embryogenic response and formed friable, type II calli. And also exhibited successful plant regeneration. Various culture media compositions based on Murashige and Skoog (1962) salts thus inve...

Cell transformation of Arabidopsis thaliana (L.) Heynh. with Agrobacterium tumefaciens (LBA4404 strain) was performed in two ways: in vitro by the transformation of root and stem explants and inplanta by the transformation of whole plants in the green­ house. Agrobacterium contained the binary plasmid pBI121 or its constructs with the fragments of carrot DC-8 promoter. The results show that tra...

Embryogenic callus was induced from culturing immature embryos of three barley cvs. Dissa, Golden Promise and Igri. Maximum embryogenic callus formation was achieved by culturing immature embryos on CC and LS medium containing 2 mg/litre and 2.5 mg/litre 2,4dichlorophenoxyacetic acid (2,4-D) respectively. Embryogenic calli were frequently produced distinguished somatic embryos on these medium. ...

Here, efficient plantlet regeneration via somatic embryogenesis from Panax quinquefolium hairy roots was reported. Callus development was optimal on MS medium containing 2,4-dichlorophenoxyacetic acid (1 mg l) and -naphthalene acetic acid (1 mg l). After a 4-week growth, calli were transferred onto MS medium with different combinations of plant growth regulators (PGRs). The highest embryogenesi...

Global warming is one of the most serious problems leading to changes in distribution areas species and biodiversity. Rhodiola quadrifida a rare plant with adaptogenic properties grows highlands narrow temperature range 2–15 °C. The aim our work was study growth content main metabolites two vitro cultures at temperatures 5, 15 25 Hairy roots calli were cultivated on agar medium for 28 days. max...

In the present study, we first attempted to achieve an efficient procedure for optimizing callogenesis from apical meristem and leaf explants of Salvia tebesana on MS media containing different concentrations BAP alone in combination with 2,4-D. Then, inducing effect nano-TiO2 (10, 60, 120 mg L−1) methyl jasmonate (50, 100, 200 µM), as abiotic elicitors were studied enhancement phenolic compoun...
