Groundnut is susceptible to a range of diseases and pests owing to its narrow genetic base. Closely related wild relatives of groundnut are diploid, and crossability between diploid wild relatives and tetraploid cultivated groundnut is difficult. Amphidiploid and autotetraploid groundnuts, which are tetraploids (also called synthetic groundnut), were developed at ICRISAT. Crossability between c...

Results of karyological study of intact plants and some callus lines of Panax ginseng are presented. In the native plants of P. ginseng the nucleus with 1 nucleolus (90%) dominate, and nucleus with 2 nucleoli is rare. One nucleolar nucleus also dominate in interphase nuclei of cells of cultivated P. ginseng (from 2006), but we also found nucleus with 2 to 3 nucleoli in the same cell lines. Inte...

Solanum section Petota has been the subject of intensive taxonomic work since the description of the cultivated potato in 1753. In total, there are 494 epithets for wild taxa and 626 epithets for cultivated taxa. Different taxonomists applied various taxonomic philosophies and species concepts to the section. Hypotheses of the number of species and their interrelationships have differed greatly...

staphylococcus aureus are important factors for infections that acquired of hospital and community. infections caused by methicillin-resistant staphylococcus aureus mainly of hospital origin, which in many countries is increasing. for this reason, many researchers have tried to find new compounds as a substitute for these antibiotics. hypericin is the active substance h.perforatum and licone ma...

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...
