BACKGROUND AND OBJECTIVES Phaffia rhodozyma is a red yeast which produces astaxanthin as the major carotenoid pigment. Astaxanthin is thought to reduce the incidence of cancer and degenerative diseases in man. It also enhances the immune response and acts as a free-radical quencher, a precursor of vitamin A, or a pigment involved in the visual attraction of animals as mating partners. The impac...

The RAPD-PCR technique was applied to identify genetic markers able to distinguish between four canid species: the arctic fox (Alopex lagopus), red fox (Vulpes vulpes), Chinese raccoon dog (Nyctereutes procyonoides procyonoides) and six breeds of the domestic dog (Canis familiaris). A total of 29 ten-nucleotide arbitrary primers were screened for their potential use in the differentiation of th...

Dalbergia oliveri is a leguminous tree of the Fabaceae family. This species is popular and valuable in Vietnam and is currently listed on the Vietnam Red List and on the IUCN Red List as endangered. Two PCR techniques using RAPD and inter-simple sequence repeat (ISSR) markers were used to make a comparative analysis of genetic diversity in this species. Fifty-six polymorphic primers (29 R...

BACKGROUND The clinical relevance of Mycobacterium szulgai isolates is unknown, and available literature focuses on case reports of M. szulgai disease. We assessed the clinical relevance of M. szulgai isolated from patients in The Netherlands. METHODS We reviewed medical files for all 21 patients in The Netherlands from whom M. szulgai was isolated during 1999-2006, applying the diagnostic cr...

Cultivar identification is a key step to avoid the formation of homonyms and synonyms of Ginkgo biloba. In this study, a new approach based on combinational utilization of polymorphic bands produced from 6 different random amplified polymorphic DNA (RAPD) primers was developed for identifying 42 Ginkgo cultivars, and a manual cultivar identification diagram that consisted of polymorphic ba...

Nicotiana alata is an ornamental plant. It is a member of family Solanasea. Tobacco (Nicotiana spp.) is one of the most important commercial crops in the world. Wild Nicotiana species, as a store house of genes for several diseases and pests, in addition to genes for several important phytochemicals and quality traits which are not present in cultivated varieties. Inter simple sequence repeat D...

Turkey is one of the most important genetic resources of the date plum, Diospyros lotus, especially in the northeastern part of the country. Authenticating the identity of germplasm resources of D. lotus would be of great value for breeding. We examined the genetic variability of 11 D. lotus genotypes sampled from Coruh Valley in Turkey. One hundred and twenty-eight DNA markers were generated b...

Curcuma is historically problematic to identify and clear their relationships for cultivar variety appearance commonly in China. Sequence-Related Amplified Polymorphism (SRAP) marker was used detect genetic among 10 China’s endemic herbs including three Chinese rarely species firstly (C. amarissima, C. flaviflora C. yunnanensis). The 2-35 polymorphic ba...

the genetic diversity of 89 flue-cured tobacco varieties was examined using 12 issr primers. these cultivarswere evaluated at the guilan tobacco research center, rasht, iran, using a 7×7 simple lattice design with two replications, and 12 morphological traits. the total number of pcr amplified products was 143 bands ranging from 450 to 3000 bp, of which 108 bands (74.28%) were polymorphic. prim...
