background: a highly efficient genetic transformation system is essential for a successful genetic manipulation of the african violet (saintpaulia ionantha wendl.).objectives: developing a particle bombardment-based genetic transformation system for the african violet.materials and methods: a local cultivar of the african violet from guilan province was used for transformation experiments. the ...

Flock house virus (FHV), a single-stranded RNA insect virus, has previously been reported to cross the kingdom barrier and replicate in barley protoplasts and in inoculated leaves of several plant species [Selling, B. H., Allison, R. F. & Kaesberg, P. (1990) Proc. Natl. Acad. Sci. USA 87, 434-438]. There was no systemic movement of FHV in plants. We tested the ability of movement proteins (MPs)...

The role of arbuscular mycorrhizal fungi (AMF) on cadmium (Cd) accumulation and on the possible attenuation of Cd stress was studied in maize plants (Zea mays L. var. Exceller). Plants inoculated or not with Glomus macrocarpum were exposed to Cd (0-20 μmol L-1), at two P levels (5 and 10 mg L-1) in the nutrient solution. The experiment was conducted in a hydroponic system, using a randomized 2 ...

The objective of this study was to establish an efficient—direct or indirect—regeneration system for pineapple (Ananas comosus L.) plants, with a high rate multiplication and that would preserve the genetic identity donor genotype (Hybrid ‘MD2’) in regenerated plants. Ten treatments, different concentrations 2,4-Dichlorophenoxyacetic (2,4-D) Picloram (P), absence presence 6-Benzylaminopurine (B...
