Previous molecular studies have suggested that the genus Cissus (Vitaceae) is not monophyletic. The majority of species are grouped, but four Australian taxa ( Cissus antarctica Vent., Cissus hypoglauca A. Gray, Cissus oblonga (Benth.) Planch., and Cissus sterculiifolia (F. Muell. ex Benth.) Planch.) form a distinct clade and Cissus opaca has now been recognized as belonging to the genus Clematicissus ( Clematicissus opaca (F. Muell.) Jackes & Rossetto). Here, we investigate relationships among the Australian Vitaceae by parsimony and Bayesian analysis of plastid trnL-trnF and nuclear internal transcribed spacer sequences and include a range of taxa that had not been previously investigated. We find no support for a close relationship between Nothocissus and the four distinct Australian Cissus, as suggested in previous morphology-based treatments. We find a robust sister relationship between Clematicissus and at least two southern American Cissus ( Cissus tweediana (Baker) Planch. and Cissus striata Ruiz & Pav.), suggesting a possible origin from an ancient southern progenitor. Finally, this study confirms the paraphyletic nature of Cayratia , with species occurring in two clades, both with Australian and non-Australian species. The necessity in future studies for data from additional and more tractable nuclear loci is also noted.

This paper is concerned with vegetative reproduction, which is the only mode of propagation in cultivated grapevines. After a brief summary of the systematics of the Vitaceae the question of the nomenclature of cultivated grapevines is discussed. Intra-varietal variability is discussed using morphological and molecular characteristics. The origins of variation are presented: mutations, foreign nucleic acids, and memory of previous environmental conditions. Grapevines provide characteristic products, leading viticulturalists to make selections among the diversity observed in the vineyard, thus decreasing diversity. Grapevines interact with various environmental agents. One example, the natural defence provided by resveratrol, is analysed, showing its direct effects against parasitic fungi and its indirect effects, both metabolic and genetic, on other organisms. Thus, the grapevine, viticulturalists, and their environment form a web of biological interactions.

In South America, the family Vitaceae is represented by 65 species divided into 2 genera: Cissus contains 64 species, whereas Vitis consists of only 1 species. Recent studies on the Neotropical Cissus reveal that with regard to species delimitation, trichome types and the morphology of fruits and seeds are more important than the traditionally used trichome density and leaf shape. Fifteen provisional species groups are recognized for South America, excluding one species whose grouping is uncertain. Future research in this area should incorporate other data (e.g., anatomical, histological, and molecular) to identify a subgeneric division in Cissus.

This paper examines the question of how the unique shoot architectural pattern of the Vitaceae, typically with leaf-opposed tendrils or inflorescences in a three-node modular repetitive pattern, can be related to the traditional concepts of monopodial and sympodial shoot development. Based on complete comparative morphological developmental studies of 13 species in six genera, supplemented with observations of 21 other taxa, we have found five shoot architectural patterns in the family. The pattern of shoot architecture is consistent within a species, but there may be more than one pattern present within a genus. Species that lack tendrils, thus exhibiting pattern 1, show sympodial growth. Taxa exhibiting patterns 2, 3, and 4, with tendrils at two of three nodes and with progressively one, two, or three axillary buds within the three-node cycle, grow monopodially, and taxa that exhibit pattern 5, with both tendrils and axillary buds at every node, achieve the pattern via either monopodial or sympodial growth, depending on the species. Although rare in the Vitaceae, pattern 1 is the only one shared with the sister family Leeaceae. We conclude that this was the original shoot architectural pattern, and that the monopodial pattern present in most species today is derived, and unique to the Vitaceae.

Phylogenetic analysis of 105 nuclear GAI1 sequences of Vitaceae provided a fairly robust phylogeny, largely congruent with the recently published chloroplast data of the family. In the GAI1 phylogeny, Cayratia Juss., Tetrastigma (Miq.) Planch., and Cyphostemma (Planch.) Alston form a clade. Cyphostemma and Tetrastigma are both monophyletic, and Cayratia is paraphyletic. Ampelopsis Michx is paraphyletic with the African Rhoicissus Planch. and the South American Cissus striata Ruiz & Pav. and its close relatives (e.g., Cissus simsiana Roem. & Schult.) nested within it. The pinnately leaved Ampelopsis forms a subclade, and the simple and palmately leaved Ampelopsis constitutes another subclade. All species of Cissus L. sampled from Asia, Africa, and Central and South America (except the C. striata complex) form a monophyletic group. Pterisanthes Blume of southeastern Asia forms a clade with the Asian Ampelocissus Planch. Vitis  L. is monophyletic and forms a larger clade with the tropical Ampelocissus and Pterisanthes . Parthenocissus Planch., forms a clade with Yua C.L. Li, with each genus reportedly monophyletic. Cissus from the Old World is paraphyletic with the neotropical core Cissus nested within it. The basal grade of Cissus consists of taxa from Africa. The African-Asian biogeographic relationships are complex, with several intercontinental disjunctions. The Northern Hemisphere Ampelopsis is most closely related to the South American C. striata complex and the African Rhoicissus .

Abstract This study aims to investigate the phylogenetic relationships within the Juglandaceae family based on the Internal Transcribed Spacer's primary sequence and secondary structures (ITS2). Comparative analysis of 51 Juglandaceae species was performed across most of the defined seven genera. The results showed that the ITS2 secondary structure's folding pattern was highly conserved and congruent with the eukaryote model. Firstly, Neighbor-joining (N.J.) analysis recognized two subfamilies: Platycaryoideae and Engelhardioideae. The Platycaryoideae included the Platycaryeae (Platycarya+(Carya+ Annamocarya)) and Juglandeae (Juglans-(Cyclocarya + Pterocarya)). The Engelhardioideae composed the (Engelhardia+（Oreomunnea+Alfaroa)). The Rhoiptelea genus was generally regarded as an outgroup when inferring the phylogeny of Juglandaceae. However, it is clustered into the Juglandaceae family and showed a close relationship with the Platycaryoideae subfamily. Secondly, the folded 3-helices and 4-helices secondary structure of ITS2 were founded in the Juglandaceae family. Therefore, these ITS2 structures could be used as formal evidence to analyze Juglandaceae's phylogeny relationship. The morphology based on the secondary structure nicely coincided with previous investigations. This study further confirms that ITS2 can serve as a valid basis for parsing evolutionary relationships in higher woody fruit trees.

Definition Of

Date of «birth» of phytosociology (phytocenology) is considered to be 1910, when at the third International Botanical Congress in Brussels adopted the definition of plant association in the wording Including Flaó and K. Schröter (Flahault, Schröter, 1910; Alexandrov, 1969). The centenary of this momentous event in the history of phytocenology devoted to the 46th edition of the Yearbook «Braun-Blanquetia», which began to emerge in 1984 in Camerino (Italy) and it has a task to publish large geobotanical works. During the years of the publication of the Yearbook on its pages were published twice work of the Russian scientists — «The steppes of Mongolia» (Z. V. Karamysheva, V. N. Khramtsov. Vol. 17. 1995), and «Classification of continental hemiboreal forests of Northern Asia» (N. B. Ermakov in collaboration with English colleagues and J. Dring, J. Rodwell. Vol. 28. 2000).

The Relationship

Empirical studies largely support the continuity hypothesis of dreaming. The present study investigated the frequency and emotional tone of dreams of truck drivers. On the one hand, the findings of the present study partly support the continuity regarding the time spent with driving/being in the truck and driving dreams and, on the other hand, a close relationship was found between daytime mood (feelings of stress, job satisfaction) and dream emotions, i.e., different dream characteristics were affected by different aspects of daytime activity. The results, thus, indicate that it is necessary to define very clearly how this continuity is to be conceptualized. The approach of formulating a mathematical model (cf. [1]) should be adopted in future studies in order to specify the factors and their magnitude in the relationship between waking and dreaming.

Abstract Despite the importance of polyploidy in the evolution of plants, patterns of molecular evolution and genomic interactions following polyploidy are not well understood. Nuclear ribosomal DNA is particularly complex with respect to these genomic interactions. The composition of nrDNA tandem arrays is influenced by intra- and interlocus concerted evolution and their expression is characterized by patterns such as nucleolar dominance. To understand these complex interactions it is important to study them in diverse natural polyploid systems. In this study we use direct sequencing to isolate and characterize nrDNA internal transcribed spacer (ITS) homeologues from multiple accessions of six different races in the Glycine tomentella allopolyploid complex. The results indicate that in most allopolyploid accessions both homeologous nrDNA repeats are present, but that there are significant biases in copy number toward one homeologue, possibly resulting from interlocus concerted evolution. The predominant homeologue often differs between races and between accessions within a race. A phylogenetic analysis of ITS sequences provides evidence for multiple origins in several of the polyploid races. This evidence for diverse patterns of nrDNA molecular evolution and multiple origins of polyploid races will provide a useful system for future studies of natural variation in patterns of nrDNA expression.
