In Turkey, only one species of Kyllinga L. (Cyperaceae) is known. This study looked at the morphology, palynology, and fruit morphology of Kyllinga brevifolia. The species are described and depicted. Furthermore, the study provides information on the species' regional ranges as well as the IUCN threat category for each species, which is assigned as LC. The pollen grains are subspheroidal in shape, with micro-echinate-perforated surface ornamentation. The fruit of Kyllinga is classified into two types: obovoid and elliptical. The fruit has a lenticular shape and is decorated with reticulate-tuberculate reticulate-tuberculate reticulate-tuberculate reticulate-tuberculate reticulate-tuberculate reticulate the pollen and fruit morphology of Kyllinga species native to our country were discovered for the first time during the course of this research. An updated and comprehensive morphological description, as well as distribution areas, are also provided.
This study was conducted to collect local Okra (Abelmoschus esculentus L.) genotypes belonging to Malvaceae (Mallow) family in the Northern Cyprus and morphological characterization of this collected material. On the other hand, due to the limited studies on collection and morphological characterization, which are the first step of breeding; the genetic potential of the local okra genotypes of Northern Cyprus has not been determined before. This research was carried out in two stages as the collection and morphological characterization of genotypes. In the first stage of the study, it was aimed to collect local okra genotypes and a total of 58 different locations were reached in line with this target and 24 samples of okra genotypes were collected from these areas. In the second year of the study, morphological characterization studies of 24 okra genotypes from the collected genetic material were carried out according to UPOV and IPGR criteria. As a result of morphological characterization showed that 24 okra genotypes can be categorized under 6 different groups. The regenerated seeds of these 6 different genotypes were preserved. In conclusion, although morphological characterization analyses performed in this study are the methods used to differentiate new species from each other, but it will be insufficient alone. Therefore, it is concluded that this method will be used in coordination with molecular characterization studies to provide more reliable results.
This study focuses on the phylogenetic relationships among taxa within the genus Echinops, in particular the taxa distributed in Turkey, since their systematic characterization and sectional taxonomy have not previously been fully determined. We used sequences of the plastid trnL-trnF, rbcL, matK and nrDNA ITS gene regions obtained from this study and GenBank to reconstruct phylogenetic relationships among Echinops taxa based on Bayesian inference. In addition, divergence times of taxa within the genus were estimated by the Bayesian method using a relaxed clock model. In the phylogenetic tree, E. acantholepis, an annual species, was first split from all other echinops taxa and this split was estimated to have occurred approximately 19.99 Mya. Next, E. emiliae, a biannual species, separates from the other species, and finally forms a group with the perennial Echinops taxa. We were also to predict differences in the rate of speciation by comparing different gene regions. The results indicate that the number of sections of the genus Echinops distributed in Turkey should be increased from three to five by the addition of the sections Psectra and Acantholepis. Furthermore, it is indicated that some taxa currently treated as subspecies may deserve recognition at the species level. Our results also support previous studies suggesting that it is appropriate to incorporate the monotypic Acantholepis in Echinops and transfer A. orientalis to the genus Echinops under the name E. acantholepis. Consequently, it is concluded that the studied gene regions were significant and informative for resolving phylogenetic relationships among the taxa of Echinops.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
