Also, the paper provides information about the hayfields floral richness, a great scientific value for Romania and Europe. The study of the flora was carried out in several stages: 2005-2008, 2013, 2017-2018. In the studied area, 397 taxa were identified, distributed in 82 families with therapeutic potential, represented by 164 medical taxa, 37 of them being in the European Pharmacopoeia 8.5. The study reveals that most plants contain: volatile oils (13.41%), tannins (12.19%), flavonoids (9.75%), mucilages (8.53%) etc. This plants can be used in the treatment of various human disorders: disorders of the digestive system, respiratory system, skin disorders, muscular and skeletal systems, genitourinary system, in gynaecological disorders, cardiovascular, and central nervous sistem disorders. In the study plants protected by law at European and national level were identified: Echium maculatum, Cephalaria radiata, Crambe tataria, Narcissus poeticus ssp. radiiflorus, Salvia nutans, Iris aphylla, Orchis morio, Orchis tridentata, Adonis vernalis, Dictamnus albus, Hammarbya paludosa etc. Keywords: Fărăgău, medicinal plants, human disease, Mureş County 1.

INTRODUCTION Two recent publications, REIFENBERGER & REIFENBERGER (1997) and SENNIKOV & ILLARIONOVA (1999) have established a new genus Wildpretia and a new section of the genus Sonchus, sect. Chrysoprenanthes. For different reasons which are discussed below each of these new ñames is considered to be unnecessary. In the first case there already exists a validly published ñame Lactucosonchus (Sch. Bip.) Svent. with priority over Wildpretia Reifenberger and in the second case, molecular studies show that Prenanthes péndula Sch. Bip., though not a true member of the ISSN 0211-7150 180 DAVID BRAMWELL genus Prenanthes is also not a Sonchus as it forms a sister dade to Sonchus along with Sventenia and Babcockia.

Most members of the alliance are endemic to the oceanic archipelagos in the phytogeographic region of Macaronesia. They display extensive morphological, ecological, and anatomical diversity, likely caused by the diverse habitats on islands and rapid adaptive radiation. As a premier example of adaptive radiation and insular woodiness of species endemic to oceanic islands, the alliance has been the subject of intensive evolutionary studies. While phylogenetic studies suggested that it is monophyletic and its major lineages radiated rapidly early in the evolutionary history of this group, genetic mechanisms of speciation and genomic evolution within the alliance remain to be investigated. We first attempted to address chloroplast (cp) genome evolution by conducting comparative genomic analysis of three representative endemic species (Sonchus acaulis, Sonchus canariensis, and Sonchus webbii) from the Canary Islands.

Other taxa have been added to the initial list of plants, so that, the total number of taxa registered by the authors in Rarău Massif amount to 1443 taxa (1133 species and 310 subspecies, varieties and forms). There was signaled out the alien taxa on the surveyed area (18 species) and those dubious presence of some taxa for the same area (17 species). Also, there were listed all the vascular plants, protected by various laws or regulations, both internal or international, existing in Rarău (i.e. 189 taxa). Finally, there has been assessed the degree of wild flora conservation, using several indicators introduced in literature by Nowak, as they are: conservation indicator (C), threat conservation indicator) (CK), sozophytisation indicator (W), and conservation effectiveness indicator (E).

  • Evaluating the Development and Potential Ecological Impact of Genetically Engineered Taraxacum Kok-Saghyz
    Evaluating the Development and Potential Ecological Impact of Genetically Engineered Taraxacum kok-saghyz DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Brian J. Iaffaldano Graduate Program in Horticulture and Crop Science The Ohio State University 2016 Dissertation Committee: Professor Katrina Cornish, Advisor Professor John Cardina Professor David Francis Professor Allison Snow Copyrighted by Brian J. Iaffaldano 2016 Abstract Natural rubber is a biopolymer with irreplaceable properties, necessary in tires, medical devices and many other applications. Nearly all natural rubber production is dependent on a single species, Hevea brasiliensis. Hevea has several disadvantages, including a long life cycle, epidemic diseases, and rising production costs which have led to interest in developing new sources of rubber with similar quality to Hevea. One species that meets this criterion is Taraxacum kok-saghyz (TK), a widely adapted species of dandelion that can produce substantial amounts of rubber in its roots in an annual growing period. Shortcomings of TK include an inability to compete with many weeds, resulting in poor establishment and yields. In addition, there is variability in the amount of rubber produced, plant vigor, and seed establishment. In order to address these shortcomings, genetic engineering or breeding may be used to introduce herbicide resistance and allocate more resources to rubber production. We have demonstrated stable transformation in Taraxacum species using Agrobacterium rhizogenes to introduce genes of interest as well has hairy root phenotypes. Inoculated roots were subjected to selection by kanamycin and glufosinate and allowed to regenerate into plantlets without any hormonal treatments or additional manipulations.

Chauhan 1,* and Prashant Jha 2 1 Queensland Alliance for Agriculture and Food Innovation (QAAFI) and School of Agriculture and Food Sciences (SAFS), The University of Queensland, Gatton, Queensland 4343, Australia 2 Department of Agronomy, Iowa State University, Ames, IA 50011, USA; [email protected] * Correspondence: [email protected] Received: 18 September 2020; Accepted: 5 October 2020; Published: 9 October 2020 Abstract: Sonchus oleraceus is becoming a hard-to-control weed in Australian cropping systems, especially in glyphosate-tolerant cotton and during summer fallows. Several biotypes of this weed have developed resistance to glyphosate as a result of common management practices under conservation agriculture systems in the country. A series of pot experiments were conducted to evaluate the effect of temperature on glyphosate efficacy and performance of several post-emergence and pre-emergence herbicides on a glyphosate-resistant (GR) and a glyphosate-susceptible (GS) biotype of S. oleraceus. At low temperatures (19–24 ◦C), no plants of the GS biotype survived glyphosate application at 570 g/ha; however, in the high-temperature regime (28–30 ◦C), 83% of the plants survived this rate of glyphosate. Similarly, for the GR biotype, up to 58% of the plants survived at 2280 g/ha of glyphosate when applied during the high-temperature regime and no plants survived this rate during the low-temperature regime. A number of post-emergence herbicides were found to be effective for S. oleraceus control. However, herbicide application delayed to the six-leaf stage compared with the four-leaf stage reduced control, especially for bromoxynil and saflufenacil herbicides.

A total of 15 invasive alien plant species under have been recorded. These include Ageratum conyzoides L., Anthemis tinctoria L., Aster pilosum Willd., Bidens pilosa L., Cichorium intibus L., Cirsium arvense (L.) Scop., Eclipta prostrata (L.) L., Emilia sonchifolia (L.) DC., Parthenium hysterophorus L., Silybum marianum (L.) Gaertn., Sonchus arvensis L., Sonchus asper (L.) Hill, Tridax procumbens L., Xanthium strumarium L., Youngia japonica (L.) DC. The analysis of invasive species reveals that most species have been introduced unintentionally through trade while only 2species intentionally introduced. Most of the species are of American origin. A better planning is needed for early detection to control and reporting of infestations of spread of new and naturalized weeds to be monitored. Keywords: Invasive alien species; Jammu district; Nativity; IAS Introduction Under the Convention on Biological Diversity, CBD (2002), invasive alien species “means an alien species whose introduction and/or spread threaten biological diversity.” These species are introduced from outside their natural range of distribution (other countries or other regions of the country) by either intentional or unintentional human activity, has established self-reproducing populations in the wild and has caused obvious changes in the local, artificial or natural ecosystems.
