Cyclotron technology is largely disseminated into the medical and radio-pharmaceutical community. In particular, cyclotron-based systems devoted to radioisotope production, both for therapy and diagnostics, are commercially available and used since many years. Today, almost 10 years after the construction of IBA’s first CYCLONE 30, a cyclotron that revolutionized cyclotron technology for medici...
During the exploration of the soil by plant roots, uptake of water and nutrients can be greatly fostered by a regular spacing of lateral roots (LRs). In the Arabidopsis root, a regular branching pattern depends on oscillatory gene activity to create prebranch sites, patches of cells competent to form LRs. Thus far, the molecular components regulating the oscillations still remain unclear. Here,...
Shoots of apple rootstocks raised in vitro were transferred to various rooting media to study the effect of different factors on root initiation and development. Various concentrations of indole-3-butyric acid (IBA) initiated rooting but maximum rooting percentage was found with 2.0 and 2.5 mg l(-1) of IBA in M7 and with 1.0 mg l(-1) of IBA in MM106. The drawback was that the roots were thick, ...
The seeds of Plukenetia polyadenia have high levels of unsaturated fatty acids and are used as medicine and food for native people in the Peruvian and Brazilian Amazon. The objective of this study was to develop a method for vegetative propagation of Plukenetia polyadenia by rooting of cuttings. The experiment was laid out in a randomized complete block design with 12 treatments and 3 replicati...
A novel method of shoot regeneration from immature floral buds along with inflorescence axis in C. borivilianum, a rare medicinal herb is described. Using this explant, axenic cultures were established with very less contamination (10%). MS medium with 2 mg l(-1) kinetin and 0.1 mg l(-1) 2, 4-dichlorophenoxyacetic acid proved to be the best for multiple shoot induction. Maximum number (35) of s...
A novel combination of plant growth regulators comprising indole-3-butyric acid (IBA), 6-benzylaminopurine (BA) and gibberellic acid (GA3) in Murashige and Skoog basal medium has been formulated for in vitro induction of both shoot and root in one culture using cotyledonary node explants of guar, (Cyamopsis tetragonoloba). Highest percentages of shoot (92%) and root (80%) induction were obtaine...
The acquisition of water and nutrients by plant roots is a fundamental aspect of agriculture and strongly depends on root architecture. Root branching and expansion of the root system is achieved through the development of lateral roots and is to a large extent controlled by the plant hormone auxin. However, the pleiotropic effects of auxin or auxin-like molecules on root systems complicate the...
This study was aimed at evaluating the growth promoting effect of symbiotic algal polyol (ribitol) and plant hormones on the lichen-forming fungi (LFF), Ramalina farinacea (CH050010 and 40403) and Ramalina fastigiata. The addition of ribitol to basal (malt-yeast extract) medium enhanced the relative growth rates of all three LFF. R. farinacea (CH050010), R. farinacea (40403) and R. fastigiata (...
