Comparative Analysis and Implications of the Chloroplast Genomes of Three Thistles (Carduus L., Asteraceae)
Comparative analysis and implications of the chloroplast genomes of three thistles (Carduus L., Asteraceae) Joonhyung Jung1,*, Hoang Dang Khoa Do1,2,*, JongYoung Hyun1, Changkyun Kim1 and Joo-Hwan Kim1 1 Department of Life Science, Gachon University, Seongnam, Gyeonggi, Korea 2 Nguyen Tat Thanh Hi-Tech Institute, Nguyen Tat Thanh University, Ho Chi Minh City, Vietnam * These authors contributed equally to this work. ABSTRACT Background. Carduus, commonly known as plumeless thistles, is a genus in the Asteraceae family that exhibits both medicinal value and invasive tendencies. However, the genomic data of Carduus (i.e., complete chloroplast genomes) have not been sequenced. Methods. We sequenced and assembled the chloroplast genome (cpDNA) sequences of three Carduus species using the Illumina Miseq sequencing system and Geneious Prime. Phylogenetic relationships between Carduus and related taxa were reconstructed using Maximum Likelihood and Bayesian Inference analyses. In addition, we used a single nucleotide polymorphism (SNP) in the protein coding region of the matK gene to develop molecular markers to distinguish C. crispus from C. acanthoides and C. tenuiflorus. Results. The cpDNA sequences of C. crispus, C. acanthoides, and C. tenuiflorus ranged from 152,342 bp to 152,617 bp in length. Comparative genomic analysis revealed high conservation in terms of gene content (including 80 protein-coding, 30 tRNA, and four rRNA genes) and gene order within the three focal species and members of subfamily Carduoideae. Despite their high similarity, the three species differed with respect to the number and content of repeats in the chloroplast genome. Additionally, eight Submitted 28 February 2020 hotspot regions, including psbI-trnS_GCU, trnE_UUC-rpoB, trnR_UCU-trnG_UCC, Accepted 11 December 2020 Published 14 January 2021 psbC-trnS_UGA, trnT_UGU-trnL_UAA, psbT-psbN, petD-rpoA, and rpl16-rps3, were identified in the study species. -
Floristic Analysis of Marmoucha's Plant Diversity (Middle Atlas, Morocco)
LAZAROA 34: 117-140. 2013 doi: 10.5209/rev_LAZA.2013.v34.n1.40753 ISSN: 0210-9778 Floristic analysis of Marmoucha’s plant diversity (Middle Atlas, Morocco) Fatima Nassif & Abbès Tanji (*) Abstract: Nassif, F. & Tanji, A. Floristic analysis of Marmoucha’s plant diversity (Middle Atlas, Morocco). Lazaroa 34: 117-140 (2013). As part of an ethnobotanical exploration among the Berbers of Marmoucha in the Middle Atlas in Morocco, a floristic analysis was conducted to inventory the existing plants and assess the extent of plant diversity in this area. Located in the eastern part of the Middle Atlas, the Marmoucha is characterized by the presence of various ecosystems ranging from oak and juniper forests to high altitude steppes typical from cold areas with thorny plants. The fieldwork was conducted over five years (2008-2012) using surveys and informal techniques. The results show that the number of species recorded in Marmoucha is 508 distributed over 83 families and 325 genera, representing 13%, 54% and 33% of species, families and genera at the national level, respectively. With 92 species, the Asteraceae is the richest family, representing 18% of the total reported followed by Poaceae and the Fabaceae . From a comparative perspective, the ranking of the eight richer families of the local flora in relation to their position in the national flora reveals a significant match between the positions at local and national levels with slight ranking differences except in the case of Rosaceae. In the study area, the number of endemics is significant. It amounts to 43 species and subspecies belonging to 14 families with the Asteraceae counting 10 endemics. -

Front cover: common dolphins in the Algeciras Bay; rock marigold Calendula suffruticosa; the Strait of Gibraltar with Morocco in the distance and Aloe succotrina and Bermuda buttercups in the foreground. Below: lunch under the bandstand in the Botanic Gardens in Gibraltar (Peter Crook). As with all Honeyguide holidays, part of the price was put towards a conservation project in the host country, in this case for El Grupo Ornitológico del Estrecho (GOES - The Ornithological Group of the Strait). It wasn’t possible to meet GOES on this occasion, but we linked up instead with their colleagues from the Tumbabuey Grupo de Anillamiento, who we watched ringing birds adjacent to the Palmones estuary – see the account for 17th February. The conservation contribution this year of £40 per person was supplemented by gift aid from those eligible, plus a cash donation of 10€ from one group member, leading to a donation of 620€, about £525, given to GOES. This is our third donation to GOES, the three donations totalling 1646€. The total for conservation contributions from all Honeyguide holidays since 1991 is £83,447, to February 2013. -

(Occasional Papers from the Herbarium Greuter – N° 1). — Bocconea. 25: 5-127. 2012. — ISSN 1120-4060 (print), 2280-3882 (online). The material collected during OPTIMA’s Iter Mediterraneum VII to the Peloponnese in 1995 has been revised. It comprises 2708 gatherings, each with 0 to 31 duplicates, collected in 53 numbered localities. The number of taxa (species or subspecies) represented is 1078. As many of the areas visited had been poorly explored before, a dozen of the taxa collected turned out to not to have been previously described, of which 9 (7 species, 2 subspecies) are described and named here (three more were published independently in the intervening years). They belong to the genera Allium, Asperula, Ballota, Klasea, Lolium, Minuartia, Nepeta, Oenanthe, and Trifolium. New combinations at the rank of subspecies (3) and variety (2) are also published. One of the species (Euphorbia aulacosperma) is first recorded for Europe, and several are new for the Peloponnese or had their known range of distribution significantly expanded. Critical notes draw attention to these cases and to taxonomic problems yet to be solved. An overview of the 11 Itinera Mediterranea that have taken place so far is presented, summarising their main results.

Genus Cynara L
Genus Cynara L. Classificazione scientifica Kingdom: Plantae Subkingdom: Tracheobionta Superdivision: Spermatophyta Division: Magnoliophyta Class: Magnoliopsida Subclass: Asteridae Order: Asterales Family: Asteraceae Subfamily: Cynaroideae (Durande) Chevall., 1828 Tribe: Cynareae Lam. & DC., 1806 Genus : Cynara L. (1753) The genus Cynara L. comprises the following seven species: • the crop complex C. cardunculus L. which includes wild forms as well as cardoon cultivars; • C. scolimus L., as the artichoke globe or cultivated artichoke; • C. syriaca Boiss.; • C. cornigera Lindley; • C. cyrenaica Maire & Weiler, • C. algarbiensis Cosson, C. baetica (Spreng.) Pau; • C. humilis L. All are native to the Mediterranean basin. The closest wild relatives of the domestic vegetables are the “wild cardoon” forms of C. cardunculus that are fully inter-fertile with the cultivated varieties; and are now ranked conspecific with the crop, and identified as the wild stock from which the domestic varieties could have been derived. These wild forms comprise the primary wild gene pool (GP1) of the cultivated artichoke. The other six wild Cynara species are more distant. A crossing programme involving five of them (C. cyrenaica was not tested) showed that they are largely cross-incompatible with C. cardunculus complex, and the rare inter-specific F 1 hybrids recovered were mostly semi-sterile. Moreover, these wild Cynara species have also diverged from C. cardunculus isozymically. They are, therefore, regarded as comprising the secondary wild gene pool (GP2) of the artichoke crop. This paper surveys the taxonomy and geographical distribution of the various wild Cynara taxa; and summarizes the available information on the genetic affinities between the crop and its wild relatives.
