The Gibberella fujikuroi species complex with Fusarium anamorphs is the causal of diverse diseases of many important plants. Many of the known species in this species complex produce a wide range of secondary metabolites. In this study, morphological characteristics of 46 isolates from rice, maize, sugarcane and onion and phylogenetic relationships of 22 isolates on the basis of ITS1-5.8S-ITS2 ...

An overview on legal regulation, taxonomy, and botanical and chemical methods of analysis of marijuana are provided. Emphases are placed on the applications of the recently developed molecular biology methods to the identification and characterization of marijuana samples. Procedures for the extraction of plant DNA, DNA amplification, restriction analysis, and sequence analysis are reviewed. Th...

Origin and evolution of tetraploid Elymus fibrosus (Schrenk) Tzvelev were characterized using low-copy nuclear gene Rpb2 (the second largest subunit of RNA polymerase II), and chloroplast region trnL-trnF (spacer between the tRNA Leu (UAA) gene and the tRNA-Phe (GAA) gene). Ten accessions of E. fibrosus along with 19 Elymus species with StH genomic constitution and diploid species in the tribe ...

In this study, the nearly complete sequence (14,519 bp) of the mitochondrial DNA (mtDNA) of the entomophagous endoparasite Xenos vesparum (Insecta: Strepsiptera) is described. All protein coding genes (PCGs) are in the arrangement known to be ancestral for insects, but three tRNA genes (trnA, trnS(gcu), and trnL(uag)) have transposed to derived positions and there are three tandem copies of trn...

The Cucurbitaceae genus Austrobryonia, with four species endemic to Australia, is described, illustrated, and placed in a phylogenetic context based on molecular and morphological data. In the Flora of Australia (Telford 1982), all four species were provisionally included in Mukia, but not formally described. Austrobryonia argillicola, A. centralis, A. micrantha, and A. pilbarensis are adapted ...

A new species, Blitum venetum Iamonico, Argenti, Sciuto & Wolf is described from the Dolomites Massif (North-Eastern Italy) on basis of molecular analyses (nuclear ITS and plastid trnL-F regions) morphological investigation. The species similar to B. bonus-henricus californicum, but it differs these taxa by characters leaves (width, pubescence, margins), inflorescence (presence bracts),...

Aneura pinguis is a thalloid liverwort species with broad geographical distribution. It is composed of cryptic species, however, the number of cryptic species within A. pinguis is not known. Five cpDNA regions (matK, rbcL, rpoC1, trnH-psbA and trnL-trnF) and the entire nuclear ITS region were studied in 130 samples of A. pinguis from different geographical regions. The relationships between the...

Phylogenetic resolution is often low within groups of recently diverged taxa due to a paucity of phylogenetically informative characters. We tested the relative utility of seven noncoding cpDNA regions and a pair of homoeologous nuclear genes for resolving recent divergences, using tetraploid cottons (Gossypium) as a model system. The five tetraploid species of Gossypium are a monophyletic asse...
