ucb-1 (pistacia atlantica × p. integrima) is a commercial rootstock for pistachio in some pistachio plantations across the world. this rootstock is very new in iran and recently, it has been used commercially in some plantations due to its high growth. propagation of this rootstock by tissue culture results in many limitations such as shoot tip necrosis (stn) and a low proliferation rate. there...
Development of a reproducible, versatile and efficient in vitro plant regeneration system is highly warranted for Indian soybean varieties for their mass multiplication in view of their commercial significance. Accordingly a protocol for direct shoot organogenesis in soybean variety JS 335 has been developed. Using cotyledonary node explants significant organogenic responses, mean shoot number ...
A key determinant of overall morphogenesis in flowering plants such as Arabidopsis thaliana is the shoot apical meristem (growing tip of a shoot). Gene r gulation networks can be used to model this system. We exhibit a very preliminary two-dimensional model including gene regulation and intercellular signaling, but omitting cell division ana' dynamical geometry. The model can be hnined to have ...
Hairy roots of horseradish (Armoracia rusticana) were induced by inoculation with Agrobacterium rhizogenes harboring Ri plasmid and cultured on phytohormone-free Murashige and Skoog medium after eliminating the bacteria. Hairy roots grew vigorously and sometimes formed yellowish calli under dark conditions. On the other hand, growth of hairy roots stopped after several weeks of culture with lig...
Successful in vitro propagation through ex vitro rooting mechanism has been achieved in Piper longum by nodal shoot segment cultures. Shoot tip explants were less proliferative compared to the nodal meristems. The explants were sterilized using 0.1% HgCl2 and cultured on Murashige and Skoog (MS) medium with various concentrations of growth regulators. MS medium supplemented with 1.0 mg/L 6-benz...
An efficient procedure for shoot regeneration was obtained by endosperm culture in Actinidia deliciosa cv. Hayward. Mature endosperm cultured on MS medium supplemented with 2 mg/l 2,4-D and 5 mg/l kinetin developed callus with 80% efficiency. Callus was transferred on MS medium containing different plant growth regulators (2,4-D, TDZ, IAA, NAA, BAP, kinetin, 2iP) for regeneration. There were si...
Background and Objective: Lead is a dangerous heavy metal for human health. This research was conducted to study the potential of a new Iranian corn (Maxima CV.) and white clover in monoculture and mixed culture for phytoremediation of Pb in a Pb polluted soil. Materials and Methods: The experimental treatments consisted of corn and white clover in a mixed culture (with 10 and 20 plant density...
