NONPARAMETRIC ANALYSIS OF  ATTITUDES TOWARD RISKY CROPS: A PLANT MOLECULAR FARMING CASE STUDY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Veeman,   Michele M.; Volinskiy,   Dmitriy; Adamowicz,   Wiktor L.
Research on plant molecular farming (PMF) is supported by public and private sectors in Canada. This may lead to benefits of new or cheaper medicines, industrial products and foods, but also be the source of appreciable risks to food safety from contamination by PMF materials, as well as potential environmental risks and costs. This study uses data from a 2005 nation-wide Canadian survey to gain insights into citizens’ perceptions of PMF benefits and risks. A series of nonparametric tests are conducted on ordinal survey data on risk and benefit assessments of respondents.  PMF is not seen as a major threat to food safety or the environment, but as a moderate indirect risk. The use of PMF to produce better and cheaper medical drugs appears to have the best...

Agrobacterium rhizogenes-mediated transformation of Hypericum sinaicum L. for the development of hairy roots containing hypericin
Provedor de dados: Brazilian Journal of Pharmaceutical Sciences
Autores: Khlifa,Heba Desouky; Klimek-Chodacka,Magdalena; Baranski,Rafal; Combik,Michal; Taha,Hussein Sayed.
Hypericum sinaicum L. is an endangered Egyptian medicinal plant of high importance due to the presence of naphthodianthrones (hypericins), which have photodynamic properties and pharmaceutical potential. We sought to assess H. sinaicum ability to develop hairy roots that could be cultured in contained conditions in vitro and used as a source for hypericin production. We used four A. rhizogenes strains differing in their plasmids and chromosomal backgrounds to inoculate excised H. sinaicum root, stem and leaf explants to induce hairy root development. Additionally, inoculum was applied to shoots held in Rockwool cubes supporting their stand after removal of the root system. All explant types were susceptible to A. rhizogenes although stem explants responded...
