“…Karyological data can also assist in the interpretation of results from molecular studies. (Johansson, 1998;Schuettpelz et al, 2002;Crawford et al, 2005;Hörandl et al, 2005). Cytogenetic data, together with morphological characters, helped to solve taxonomic problems in tracing the origin of hybrids and even provided clarity of possible taxonomic decisions (Bailey and Stace, 1992).…”

Ranunculus L. genus has 84 species in Turkey, when subspecies and varieties are included in this number, it is represented by a total of 102 taxa. 22 of which are endemic, the endemism rate is 21.5%. Since many members of the genus Ranunculus cannot be distinguished from each other with definite differences, they have been tried to be defined and expressed as species complexes taxonomically. Most of the systematic studies are in the direction of regulating such complexes. It is known that karyological characters are of great importance in the phylogenetic classification of the Ranunculaceae family. In this study, it is aimed to reveal the karyological characteristics of three species which are very similar to each other, in Group A of Ranunculus subgenus of Ranunculus L. in Volume 1 of Flora of Turkey morphologically by using cytogenetic methods. In this context, the karyological characteristics of R. diversifolius Boiss. & Kotschy, R. poluninii Davis and R. crateris Davis species have been determined. R. poluninii and R. crateris species are endemic to our country and are Iran-Turanian element. R. diversifolius species, on the other hand, is distributed in the East of Turkey. It has been determined that all three species whose chromosomal characteristics were examined are diploid and their chromosome numbers are x=8, 2n=16. It has also been determined that these three species, which are morphologically similar to each other, are the same in terms of chromosome number but different in terms of chromosome morphology and each species has its own characteristics. With this study, the chromosomal characteristics of these three species have been determined for the first time by us and have been brought to the literature.

“…Molecular techniques, now an integral part of biosystematic studies, are used to clarify genetic affinities (phylogenies) among related species and are specifically applied in biosafety evaluation to determine the closest wild relatives of crop plants and validate traditional taxonomic circumscriptions. To this end, molecular data have been used in the biosystematics of plants (Crawford et al, 2005;Marhold and Stuessy, 2011), pathogens (Crous et al, 2015), insects (Brites-Neto et al, 2014;Braby and Williams, 2016) and weeds (Les et al, 2002).…”

The second Sustainable Developmental Goals (SDG), among the seventeen SDG, is concerned with the pursuit of global food security and agricultural sustainability, which become the key to the success of the entire SDG. Whereas agricultural production and productivity are heavily threatened by the incidence of pests that inflict huge losses in various forms. This calls for prompt applications of biotechnology for the fast, accurate and reliable means for characterization of plant generic resources and pests as it is the pre-requisite and gateway for designing appropriate plant protection and production strategies. It is imperative that pests be identified properly so that judicious use of the literature can be made and sustainable management strategies can be implemented at the right stage. To this end, the application of biotechnology has made significant advances for reliable characterization of plant genetic resources as well as accurate diagnosis of pests, study of their genetic diversity and variability, detailed mechanisms of their transmission and evolutionary relationships. Accordingly, this review article covers the comprehensive account of the various molecular techniques, genome mapping and OMICS sciences utilized for characterization plants and pests that ultimately allow the detailed study of the biology and epidemiology of pests at any stage of their life cycle. The resulting data are eventually employed for enhancing successful implementation of sustainable plant protection and production strategies. In conclusion, the increasing projections of transboundary pests, environmental and abiotic factors together with the continuous scientific advancements and breakthroughs have made biotechnology to be an important engine of bioeconomy for generating invaluable products, processes and services.

Revised systematics of Mediterranean Arundo (Poaceae) based on AFLP fingerprints and morphology

The systematics of the genus Arundo (Poaceae) remains poorly resolved because of the overlap of morphological characters classically used in the taxonomy of the genus and insufficient variation of DNA sequences. The main aim of this study is to delimit genetic clusters with AFLP fingerprints and to compare them with morphological data. On the basis of extensive sampling in the Mediterranean area, AFLP markers clearly showed five clusters. Despite overlapping values, morphometric analyses strongly confirm these clusters, and new qualitative features allow the recognition of five taxa: the Taiwanese A. formosana, the cosmopolitan A. donax, the circum‐Mediterranean A. micrantha, the Italo‐Balkan A. plinii and the Franco‐Ligurian A. donaciformis (Loisel.) Hardion & al. comb. nov. Additionally, this study shows a correlation between genetic diversity, caryopsis production and ploidy level. However, the lack of genetic diversity for A. micrantha and A. donax in the Mediterranean area remains enigmatic.
