Abstract The present work deals with natural and subnatural forests of Pinus pinaster Aiton subsp. pinaster of Liguria and Tuscany regions. After a short introduction on the taxonomy and biogeography of Pinus pinaster subsp. pinaster, three new associations are described: Erico scopariae-Pinetum pinastri, Erico arboreae-Pinetum pinastri and Buxo sempervirentis-Pinetum pinastri. These associations belong to the new alliance Genisto pilosae-Pinion pinastri (Quercetalia ilicis order, Quercetea ilicis class). It also describes the new shrub association Genisto pilosae-Buxetum sempervirentis, dynamically linked to the forest of pine called Buxo sempervirentis-Pinetum pinastri. Characteristic and differential species, ecology, distribution, dynamic and catenal relationships of the new Pinus pinaster subsp. pinaster associations and the new alliance are also described.

Abstract Gloriosa katangensis Maroyi (Colchicaceae) is a rare and little known plant species, endemic to the Democratic Republic of Congo (Kinshasa). Results of this investigation are based on herbarium studies undertaken at the National Herbarium of the Netherlands, Wageningen University branch (WAG) and the National Herbarium and Botanic Gardens, Harare, Zimbabwe (SRGH), between January 2008 and 30 September 2011. Additional herbaria specimens of the genus Gloriosa L. were received on loan from B, BM, BR, C, COI, F, K, L, P, S, U and UPS. The diagnostic morphological characters that distinguish G. katangensis from the other Gloriosa species are discussed. Detailed description, illustration, distribution map, ecological data and taxonomic history of G. katangensis are provided. International Union for Conservation of Nature status of the species has been assigned as Critically Endangered because of the restricted area of occupancy, extent of occurrence of the species and also because none of the collections of the species made so far in the Democratic Republic of Congo has been in protected areas. Publication of detailed taxonomic information on G. katangensis contributes to a better understanding of the diversity of the genus Gloriosa in tropical Africa and the conservation of this critically endangered species.

Abstract Features of the adaxial and abaxial surface microstructure of Arbutus unedo L. and Arbutus andrachne L. are evaluated as possible consistent parameters contributing to the wetness of leaves. The abaxial leaf surface of A. andrachne and A. unedo was determined to be more hydrophobic than the adaxial leaf surface. Hydrophobicity may be of particular importance for the ecophysiological status of the hypostomatic leaves of both Arbutus species, which exhibit a long lifespan and are exposed to various environmental stimuli. Water repellence may also be correlated to the increased presence of surface wax. Lipid analysis of the leaves of both plant species revealed an abundance of α-linolenic acid, with palmitic acid as the second major contributor, followed by linoleic and oleic acid. Oleic and linoleic acid were present in slightly larger percentages in A. andrachne compared with A. unedo, whereas myristic, palmitic and α-linolenic acids were found in elevated percentages in A. unedo. The fatty acid composition analysis of the leaf wax of A. andrachne and A. unedo ranged from C16 to C26, with fatty acids of an even longer chain length detected in the case of A. andrachne. Despite the similar fatty acid composition of total lipids, the composition of the wax fraction showed differences between the two Arbutus species, which may partly contribute to the foliar surface properties of the two species.

Abstract Francesco Cupani, a seventeenth century Sicilian botanist, developed a network of scientific exchanges and connections with the most important scientists of his time. Despite living in considerable isolation, he managed, above all thanks to Sherard, to correspond and exchange with Ray, Commelin, Tournefort, Triumfetti, Volkamer and Böhm. He participated in the intellectual process and debate on the method of classifying plants that he undertook following the comparison and contrast between Linnaeus and Buffon, in formulating the Linnaeus method and in creating the concepts of genera and species. Cupani and other contemporary botanists were not able to establish a system of plant classification. Each of them was so engaged in researching the distinctive characters of individual plants, in avoiding duplications and synonyms, that they could not grasp what they had in common. Linnaeus, giving them notable recognition, placed them in the category of the “Curious”. These pre-Linnaean researchers contributed to the difficult process of overcoming the rigidity of late-Aristotelian classifications, thanks also to the invention of a “scientific network” that enabled the mutual debate and exchange of botanical material (publications, iconography, seeds and exsiccata).

Abstract Clerodendrum indicum (L.) O. Kuntze (Lamiaceae) is characterized by some unique features in its seedling phenology and germination. The epigeal cryptocotylar type of seedling of the species is uncommon among dicotyledons. Significant morphological characters of the seedling of the species are thickened hypocotyl, a pair of cryptocotylar epigeal cotyledons and five pairs of eophylls in opposite decussate phyllotaxy. Each eophyll is ovate in shape with dentate margins and sub-acute apex. The eophylls are readily distinguishable from the foliage leaves of adult individuals by their architecture and phyllotaxy. The features are helpful in identifying an individual of the species at its juvenile stage, before flowering and fruiting. Clerodendrum indicum is the only known species of the order Lamiales that is characterized by the epigeal cryptocotylar type of seedling.

Abstract The paper presents new records for 18 vascular plant species from six Eurasian countries. Three taxa (Lepidium densiflorum, Stipa czerepanovii, Xanthium albinum) are reported from Kazakhstan, one (Ranunculus schmakovii) from Mongolia, three (Dianthus campestris, Ranunculus kauffmannii, Viola suavis) from Poland, five (Eragrostis amurensis, Linum catharticum, Ludwigia peploides subsp. stipulacea, Pyrethrum mikeschinii, Solidago canadensis) from Tajikistan, five (Clinopodium menthifolium, Juncus effusus, Mollugo cerviana, Poa sphondylodes, Vulpia myuros) from Russia, and one (Orobanche alba subsp. xanthostigma) from Georgia. Ten of the taxa presented (Clinopodium menthifolium, Dianthus campestris, Eragrostis amurensis, Juncus effusus, Lepidium densiflorum, Mollugo cerviana, Solidago canadensis, Viola suavis, Vulpia myuros and Xanthium albinum) are regarded as alien to the studied areas, whereas the remaining eight are native elements to the flora of the countries. For each species, synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition and differentiation of the species from the most similar occurring in a given country, as well as a list of localities recorded (often far from the previously known areas), are presented.

Abstract Plants produce many terpenoids including gibberellins and many commercially important secondary metabolites. The final steps of terpenoid production involve terpene synthase (TPS) enzymes. The origin of plant TPS is not known; searches for TPS showed their presence in all plant groups except algae. Although many plants have several genes in their genome that encode TPS enzymes, the bryophyte Physcomitrella patens (Hedw.) Bruch & Schimp. possesses only one bifunctional ent-kaurene synthase (PpCPS/KS), which produces both 16α-hydroxykaurane and ent-kaurene (the precursor of gibberellins). This protein shares characteristics of two unifunctional TPS of higher plants – ent-copalyl diphosphate synthase (CPS) and ent-kaurene synthase (KS). Bifunctional TPS are also found in fungi. In this study, the bifunctional PpCPS/KS has been characterized by some bioinformatics tools. Comparative analysis of PpCPS/KS with some fungal and plant TPS as well as terpenoid-producing bacterial enzymes has been performed. The results indicate that bifunctional TPS came from fungi to bryophytes, probably by horizontal gene transfer and unifunctional TPS gradually evolved from bifunctional TPS in higher plants.

Abstract We report the isolation of two full-length mariner-like elements (MLEs) from a bamboo species (Phyllostachys edulis) by chromosome walking using a modified magnetic enrichment procedure. Ppmar1 is 3472 base pairs (bp) in length with 28-bp perfect inverted terminal repeats (ITRs) and a 1986-bp open reading frame (ORF) encoding transposase, whereas Ppmar2 is 2679 bp in length with the 27-bp perfect ITRs and the 1877-bp ORF encoding transposase. Ppmar1 and Ppmar2 share the typical ITR consensus sequences of plant MLEs (5′-CTC CCT CCR T-3′, where R is A or G) and the typical TA/AT target site duplications. Phylogenetic analysis demonstrated that Ppmar1 belongs to clade A2 and Ppmar2 to clade C of plant MLE subfamilies. The two transposases encoded contain intact DNA-binding motifs and a DD39D catalytic domain and many residues previously shown to be critical for transposase activity are conserved in Ppmar1 and Ppmar2. All the above results imply that both transposons are likely to be naturally active. Cloning of two full-length mariner-like elements would provide a foundation for the investigation of transpositional activity of moso bamboo MLE.

Abstract Paracaryum is a distinctive genus that includes many endemic taxa, and several of these endemics from the Irano-Turanian phytogeographical region are of special interest. In Turkey, the genus includes 28 species, of which 21 are endemic. Paracaryum leptophyllum, Paracaryum ponticum and Paracaryum artvinense occur in northeastern Turkey. The nomenclature, lectotypification, morphology and conservation status of these taxa are examined in the current study. According to these data, P. ponticum must be treated as a distinct species; P. artvinense must be reduced to synonymy with P. ponticum. In this study, P. ponticum and P. leptophyllum are re-classified at the subgenus level, and the lectotypifications of the names are designated. The amended descriptions in comparison with the related species P. ponticum and P. leptophyllum, an identification key, nutlet pictures and a chorological note are provided.

In Turkey, the genus includes 28 species, of which 21 are endemic. Paracaryum leptophyllum, Paracaryum ponticum and Paracaryum artvinense occur in northeastern Turkey. The nomenclature, lectotypification, morphology and conservation status of these taxa are examined in the current study. According to these data, P. ponticum must be treated as a distinct species; P. artvinense must be reduced to synonymy with P. ponticum. In this study, P. ponticum and P. leptophyllum are re-classified at the subgenus level, and the lectotypifications of the names are designated. The amended descriptions in comparison with the related species P. ponticum and P. leptophyllum, an identification key, nutlet pictures and a chorological note are provided. The conservation status of these taxa is discussed.","PeriodicalId":7129,"journal":{"name":"Acta Botanica Gallica","volume":"5 1","pages":"117 - 123"},"PeriodicalIF":0.0,"publicationDate":"2015-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12538078.2015.1014064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59706477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
