Molecular data was reviewed for the woody bamboo account in the English language Flora of China. The implications for recognition of suprageneric taxa and genera, for macro-morphological characters used in classification systems, and for the inferred biogeographical history of Asian bamboos are discussed. Support was not found for large supertribes based on inflorescence structure. Instead a re...
Abstract Background Phlebotomine sand flies are the principal vectors of Leishmania spp. (Kinetoplastida: Trypanosomatidae). Information on in Central Europe is scarce and, to date, Austria, only Phlebotomus mascittii has been recorded. In 2018 and 2019, entomological surveys were conducted Austria with aim further clarify fly distribution species composition. Results a Ph. simici specimen was ...
Deprea (Solanaceae) is a small South American genus of 10 species occurring in Andean areas from Venezuela to Bolivia. The circumscription of Deprea has been repeatedly modified in recent years, with new species being described and others transferred into or out of the genus. The relationships of Deprea to other genera of Solanaceae are still poorly understood, although it seems to be closely r...
Research on arbuscular mycorrhizal fungi (AMF), presently, is at the crossroads. Some aspects like their beneficial role in overall plant growth under diverse edaphic conditions, have been thoroughly investigated and further, there is no second opinion to the advocacy of their development as bioinoculants. However, the biosystematics, culturability and field performance evaluation of this group...
There seem to be a certain degree of reluctance in accepting ILP-based methods as part of the range of molecular markers that are classically used for plant genotyping. Indeed, since DNA polymorphism results from difference in length of fragments amplified from specific gene loci, not anonymous sequences, the number of markers that can be generated is sometime inadequate for classical phylogeny...
Amplified fragment length polymorphism (AFLP) was used to investigate polymorphism among 43 Hirsutella thompsonii isolates (33 from Thailand) obtained from various mite species. The outgroups were an unidentified Hirsutella isolate along with Hirsutella nodulosa and Hirsutella kirchneri. Phylogenetic analyses of the AFLP data showed significant variation among isolates and the existence of thre...
This work investigates the phylogenetic relationships within Grimmia Hedw. using 33 species of Grimmia and ten outgroup species from the Funariidae and the Dicranidae using a combination of two molecular markers and 52 morphological and anatomical characters. Plastid (trnL-trnF and rps4) DNA sequences were used to reconstruct the molecular phylogeny of Grimmia. The 33 chosen Grimmia species rep...
Sulla genus (Hedysarea) includes six Mediterranean species constituting an important phytogenetic patrimony primarily used to promote feed production chiefly in arid and semi arid regions. In order to perform a phylogenetic analysis of Sulla species, both morphological and molecular data were used. The morphological data was comprised of 10 characters, while the molecular characters were compri...
The Nicodrilus genus is not accepted in the nomenclature according to ICZN; Aporrectodea term is used. However, according to Bouché, Aporrectodea and Allolobophora genera are not homogeneous and are supposed as polyphyletic genera. The aim is to study the phylogenetic structure of Aporrectodea genus in order to verify its cladistic nature and its taxonomical validity. In this work, five species...
Amplified Fragment Length Polymorphism (AFLP) markers are formed by selective amplification of DNA fragments from digested total genomic DNA. The technique is popular because it is a relatively inexpensive way to produce large numbers of reproducible genetic markers. In this paper, we describe a Bayesian approach to modeling AFLP marker evolution by nucleotide substitution and an MCMC approach ...
