ABSTRACT- Desert truffles are hypogeous ascomyceteous ectomycorrhizal fungi, occurring in arid and semi-arid ecosystems. A PCR-based method was developed for the identification of 3 major desert truffles of Iran: Terfezia claveryi, Tirmania pinoyi and Tirmania nivea based on internal transcribed spacers of rDNA. Two specific PCR primers were designed for T. claveryi, 4 for T. pinoyi, and 2 for ...

fungi associated with ascocarps of terfezia claveryi, tirmania nivea, t. pinoyi, picoa lefebvrei and p. juniperi in iran showed a wide range of genera and species in 94 samples collected during 2005–2009 from different regions including fars, systan and baluchestan, kerman, east azarbaijan, khuzestan, kermanshah and hormozgan provinces. thirty two species belonging to 21 genera were recovered f...

terfezia, picoa and tirmania, so called desert truffles, are mycorrhizal fungi mostly endemic to arid and semi-arid areas of the mediterranean region, where they are associated with helianthemum and carexspecies. the aim of this work was to study the identification, molecular analysis, distribution and hosts of these pezizalean hypogeous fungi in iran. among the specimens, terfezia claveryi, ti...

The ITS region including the 5.8S gene of rDNA of three desert truffle species were amplified using ITS4 and ITS1 primers. The ITS sequences were compared to those of other related authentic sequences obtained from GenBank. Among 12 specimens studied, seven isolates corresponded to Terfezia claveryi reported by other authors. Iranian T. claveryi specimens had an average similarity of 99.4% (ran...

BACKGROUND The root of Boehmeria spp (ramie) is a hepatoprotective Chinese herbal medicine. Medicinal properties vary between Boehmeria nivea var. nivea and Boehmeria nivea var. tenacissima, which are local species found in Taiwan. As commercial preparations may use either species, there is a need for a rapid and simple assay to identify variants for quality control. METHODS Four methods were...

The transposable element Tam3 of Antirrhinum majus is capable of causing large-scale chromosomal restructuring. It induced a large deletion at the nivea locus, to produce the allele niv-:529. The deletion removed the entire nivea coding region while the element remains intact with the potential to induce further rearrangements. Genetic experiments showed that the endpoint of the deletion (calle...
