    Opis:
    This review focuses on plant-to-plant horizontal gene transfer (HGT) involving the three DNA-containing cellular compartments. It highlights the great incidence of HGT in the mitochondrial genome (mtDNA) of angiosperms, the increasing number of examples in plant nuclear genomes, and the lack of any convincing evidence for HGT in the well-studied plastid genome of land plants. Most of the foreign mitochondrial genes are non-functional, generally found as pseudogenes in the recipient plant mtDNA that maintains its functional native genes. The few exceptions involve chimeric HGT, in which foreign and native copies recombine leading to a functional and single copy of the gene. Maintenance of foreign genes in plant mitochondria is probably the result of genetic drift, but a possible evolutionary advantage may be conferred through the generation of genetic diversity by gene conversion between native and foreign copies. Conversely, a few cases of nuclear HGT in plants involve functional transfers of novel genes that resulted in adaptive evolution. Direct cell-to-cell contact between plants (e.g. host-parasite relationships or natural grafting) facilitate the exchange of genetic material, in which HGT has been reported for both nuclear and mitochondrial genomes, and in the form of genomic DNA, instead of RNA. A thorough review of the literature indicates that HGT in mitochondrial and nuclear genomes of angiosperms is much more frequent than previously expected and that the evolutionary impact and mechanisms underlying plant-to-plant HGT remain to be uncovered.

    Opis:
    Evergreen plants are an important component of many ecosystems of the world and occur in numerous evolutionary lineages. In this article we review phenotypic traits of evergreen woody angiosperms occurring in habitats that regularly experience frost. Leaf anatomical traits such as sclerenchymatic tissues or prominent cuticles ensure mechanical strength while often enhancing tolerance of water deficit. The low ratio of photosynthetic to nonphotosynthetic tissues as well as modified cell wall structure and nitrogen allocation patterns in evergreen leaves result in lower mass-based photosynthetic rate and photosynthetic nitrogen use efficiency in comparison with deciduous leaves. Their photosynthetic apparatus is adapted for the survival of frost in a down-regulated state with potential for photosynthetic activity in winter during periods of permissive temperatures. Leaf structure interacts with the mechanisms of frost survival. Stem xylem in evergreen plants tends to contain smaller diameter conduits incurring greater resistance to freeze/ thaw induced cavitation than in deciduous plants, although at the cost of reduced hydraulic efficiency. In contrast, no such differences in hydraulic conductivity have been documented at the leaf level. There is evidence for reduced structural plasticity of evergreen leaves in response to variability in irradiance, however photosynthetic downregulation occurs in mature leaves in response to self shading. Some evergreen species exhibit slow leaf development and “delayed greening”, while in many species aging is also a very protracted process. Finally, evergreen leaves may participate in carbohydrate and, less obviously, in nitrogen storage for the support of spring shoot and foliage growth, although the importance of this function is under debate. In conclusion, the evergreen leaf habit is correlated with numerous structural and functional traits at the leaf and also at the stem level. These correlations may generate trade-offs that shape the ecological strategies of evergreen plants.

    Opis:
    The qualitative and quantitative studies, presented in this article, on wood anatomy of various species belonging to ancient Magnolia genus reveal new aspects of phylogenetic relationships between the species and show evolutionary trends, known to increase fitness of conductive tissues in angiosperms. They also provide new examples of phenotypic plasticity in plants. The type of perforation plate in vessel members is one of the most relevant features for taxonomic studies. In Magnolia, until now, two types of perforation plates have been reported: the conservative, scalariform and the specialized, simple one. In this paper, are presented some findings, new to magnolia wood science, like exclusively simple perforation plates in some species or mixed perforation plates – simple and scalariform in one vessel member. Intravascular pitting is another taxonomically important trait of vascular tissue. Interesting transient states between different patterns of pitting in one cell only have been found. This proves great flexibility of mechanisms, which elaborate cell wall structure in maturing tracheary element. The comparison of this data with phylogenetic trees, based on the fossil records and plastid gene expression, clearly shows that there is a link between the type of perforation plate and the degree of evolutionary specialization within Magnolia genus.

    Opis:
    The early halophytic angiosperm Pseudoasterophyllites cretaceus from the Cenomanian Peruc Korycany Formation of the Bohemian Cretaceous Basin and from the Late Albian of the Northern Aquitanian Basin is redescribed. The plant is characterized by semi−whorled linear, and heavily cutinized leaves with paracytic stomata. Stamens associated with P. cretaceus possess an apically emerging connective that possesses the same epidermal cell pattern as the leaves. The stamens are massive, tetrasporangiate, and contain Tucanopollis pollen, thus clearly indicating affinities of P. cretaceus to the basal angiosperms. The plants that co−occur with P. cretaceus in semi−autochtonous taphocoenoses include the conifer Frenelopsis alata, which was likely a halophyte or halo−tolerant glycophyte growing in habitats close to the sea.

    Opis:
    Of the 30 extant orders of insects, scale insects (Hemiptera: Coccoidea) have one of the best fossil records among insects that probably extends to the early Mesozoic. Most fossil Coccoidea records are of adult males which have been trapped in amber, whereas adult females are less common, probably because of their sedentary occurrence on plants. Descriptions, photos, and SEM micrographs are presented of over 250 well−preserved scale covers of adult females and nymphal stages of armoured scale insects (Hemiptera: Coccoidea: Diaspididae) which were found on dicotyledonous and monocotyledonous fossil leaves in Middle Eocene deposits from Germany. The structure of these fossil scale covers closely agrees with that of extant Diaspididae. These armoured scale insects belong to the subfamily Aspidiotinae. The age of this insect−plant association—47 to 44 million−year−old—indicates that the Diaspididae have a long history in the Palaearctic region.
