tissue culture is one of the common methods for propagation of apple clones. however, low survival and poor growth of these plants, after transplanting, limit the widespread use of this technique. the success rate of this method can be increased by using bioagents such as arbuscular mycorrhizal fungi (amf). in this study, effect of mycorrhizal symbiosis and culture media on growth and establish...

The colonisation intensity and composition of the mycorrhizal community in the aquatic plants Lobelia dortmanna and Littorella uniflora were studied. The mycorrhizal fungi were characterised by fungal specific nested PCR and sequencing using the 5'-end of the LSU rDNA as target. For this, primers for the clade of Acaulospora, the clade including Glomus mosseae and G. intraradices and the clade ...

Attachment of certain bacteria to living arbuscular mycorrhizal fungal extraradical hyphae may be an important prerequisite for interactions between these microorganisms, with implications for nutrient supply and plant health. The attachment of five different strains of gfp-tagged soil bacteria (Paenibacillus brasilensis PB177 (pnf8), Bacillus cereus VA1 (pnf8), Pseudomonas fluorescens SBW25<gf...

background and objectives: one of the most important limiting factors of crop growth in the arid and semi-arid regions, is water deficit stress. mycorrhizal fungi are one of the most important microorganisms in the rhizosphere. the effects of these fungi apply via changes on some of the characteristics of roots and nutrient uptake in host plants in drought conditions. however, symbiotic mycorrh...

Abstract Litter is the crucial carrier of soil nutrition transformation. The influence arbuscular mycorrhizal (AM) fungi on nutrient acquisition in plants has been widely recognized. However, nutrient-deficient karst habitat, how competitive utilize nutrients regulated by AM via litter remain largely unknown. experimental treatments included inoculation with or without Glomus etunicatum, additi...

BACKGROUND Gloriosa superba produces an array of alkaloids including colchicine, a compound of interest in the treatment of various diseases. The tuber of Gloriosa superba is a rich source of colchicine which has shown anti-gout, anti-inflammatory, and anti-tumor activity. However, this promising compound remains expensive and Gloriosa superba is such a good source in global scale. Increase in ...
