The utility of DNA barcoding for identifying representative specimens of the circumpolar tree genus Fraxinus (56 species) was investigated. We examined the genetic variability of several loci suggested in chloroplast DNA barcode protocols such as matK, rpoB, rpoC1 and trnH-psbA in a large worldwide sample of Fraxinus species. The chloroplast intergenic spacer rpl32-trnL was further assessed in ...

To determine the evolutionary relationships among some members of geophytes collected from their natural habitat in Kulp-Diyarbakır we carried out molecular phylogenetic analysis one nuclear DNA (nrDNA) region (internal transcribed spacer, ITS) and chloroplast (cpDNA) (intergenic spacer trnL-F). Despite using maximum likelihood done by two different source show differences it was identified tha...

The coding region of the mat K gene and two intergenic spacers, psb A-trn H and trn L(UAA)-trn F(GAA), of cpDNA were sequenced to study phylogenetic relationships of 32 Paeonia species. In the psb A-trn H intergenic spacer, short sequences bordered by long inverted repeats have undergone inversions that are often homoplasious mutations. Insertions/deletions found in the two intergenic spacers, ...

Abstract Drought stress is one of the most severe abiotic stresses affecting adversely plant growth, crop production, and various metabolic processes. Using seaweed extract in mitigating water adverse effects highly important for production. The present study discussed physiological role ( Sargassum denticulatum ) improving wheat tolerance to stress. Water (40% field capacity) caused significan...

Khoshsokhan, M., Kazempour Osaloo, S., Saadatmand, S. & Attar, F. 2010 06 30: Molecular phylogeny of Rochelia (Boraginaceae) based on nrDNA ITS and cpDNA trnL-F sequences. -Iran. J. Bot. 16 (1): 22-29. Tehran. We here present molecular phylogeny of the genus Rochelia (Boraginaceae-Eritrichieae). A total of 8 species of Rochelia and 2 species of Lappula as outgroups were included in analyses usi...

The effects of rapid, recent uplift of the Hengduan Mountains on evolution and diversification of young floristic lineages still remain unclear. Here, we investigate diversification of three closely related Saxifraga species with a distribution restricted to the Hengduan Mountains (HM) and southern Tibet, and comment on their taxonomy based on molecular evidence. Three chloroplast DNA fragments...
