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.","PeriodicalId":7129,"journal":{"name":"Acta Botanica Gallica","volume":"162 1","pages":"157 - 164"},"PeriodicalIF":0.0,"publicationDate":"2015-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12538078.2015.1040997","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59706164","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}

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.","PeriodicalId":7129,"journal":{"name":"Acta Botanica Gallica","volume":"162 1","pages":"225 - 232"},"PeriodicalIF":0.0,"publicationDate":"2015-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12538078.2015.1039579","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59706058","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}

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).","PeriodicalId":7129,"journal":{"name":"Acta Botanica Gallica","volume":"162 1","pages":"215 - 223"},"PeriodicalIF":0.0,"publicationDate":"2015-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12538078.2015.1039580","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59706101","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}

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.","PeriodicalId":7129,"journal":{"name":"Acta Botanica Gallica","volume":"162 1","pages":"139 - 152"},"PeriodicalIF":0.0,"publicationDate":"2015-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12538078.2015.1017774","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59706499","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}

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.","PeriodicalId":7129,"journal":{"name":"Acta Botanica Gallica","volume":"162 1","pages":"127 - 137"},"PeriodicalIF":0.0,"publicationDate":"2015-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12538078.2014.999117","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59705583","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}
