Arsenic uptake by plants is species-specific and its level in terrestrial of uncontaminated sites ranged from 0.009 to 1.5 mg/kg. Plants with high metal or metalloid capability their biomass are called hyperaccumulators. The most efficient arsenic (As) hyperaccumulator belongs Pteridaceae species Pteris vittata L. Pityrogramma calomelanos L., both can accumulate more than 8000 mg/kg As above-gr...
To obtain extracts rich in the organic forms of selenium with putative cancer-preventive properties more effective than those of selenizedyeast, Lentinula edodes mycelia were cultivated in media enriched with selenium at concentrations from 0 to 20 μg mL, by addition of sodium selenite either before inoculation or after three days of mycelial growth. The total selenium content of submerged cult...
Agarwood is the fragrant resinous material mainly formed from species of Aquilaria. 2-(2-phenylethyl)chromones, especially the highly oxidized 5,6,7,8-tetrahydro-2-(2-phenylethyl)chromones, are the main representative compounds from agarwood. It is important to determine whether agarwood in trade is from cultivated trees or natural trees in the Convention on the International Trade in Endangere...
To examine if the cultivation process has reduced the genetic variation of modern cultivars of the traditional Chinese medicinal plant, Coptis chinensis, the levels and distribution of genetic variation was investigated using ISSR markers. A total of 214 C. chinensis individuals from seven wild and three cultivated populations were included in the study. Seven ISSR primers were used and a total...
Bromeliads are of great economic importance in flower production; however little information is available with respect to genetic characterization of cultivated bromeliads thus far. In the present study, a selection of cultivated bromeliads was characterized via inter-simple sequence repeat (ISSR) markers with an emphasis on genetic diversity and population structure. Twelve ISSR primers produc...
