Taxonomic revision of the family closteroviridae with special reference to the grapevine leafroll-associated members of the genus ampelovirus and the putative species unassigned to the family

Abstract: New insights into the genetic structure and variability of grapevine leafroll-associated viruses (GLRaVs) gained through worldwide efforts in the last decade or so, and the production and use of new sets of serological reagents, have provided the solid foundation on which the present revision of the taxonomic structure of the family Closteroviridae, and the genus Ampelovirus in particular, is based. A comparative examination of the amino acid sequence divergence of three taxonomically relevant genes [RNA-dependent RNA polymerase (polymerase), heat shock protein 70 homologue (HSP70h) and coat protein (CP)] disclosed a difference among Grapevine leafroll-associated virus 4 (GLRaV-4), -5, -6 and -9 and a group of more recently described viruses (GLRaV-Pr, GLRaV-De and GLRaV-Car) below the 25% limit recently set by the International Committee on Taxonomy of Viruses (ICTV) as a discriminating criterion for the identification of species in the family Closteroviridae. This, plus the recognition that GLRaV-4, -5, -6 and -9 are serologically related, have similar biological and epidemiological traits, and that these viruses and GLRaV-Pr, GLRaV-De, GLRaV-Car have a genome with the same structure and size, supports the notion that they are all genetically divergent variants of a single species, GLRaV-4. The genus Ampelovirus is split into two subgroups designated I and II in recognition of the wide difference in the size and structure of the genome of the present members. Finally, the establishment of a fourth genus within the family Closteroviridae, comprising the unassigned putative species Grapevine leafroll-associated virus 7 (GLRaV-7), Little cherry virus 1 (LChV-1) and Cordyline virus 1 (CoV-1), is justified based on their molecular and biological characteristics that differ from those of members of the other three genera of the family.

Biomass co-firing technology with policies, challenges, and opportunities: A global review

Abstract: The urgency of reducing Greenhouse gas (GHG) emission is increasing and countries around the world have begun investing a substantial amount of resources into renewable energy sources Biomass co-firing can have a very influential role in achieving this new energy target as it can reduce the potential environmental impacts associated with the combustion of fossil fuels Greenhouse gases such as CO2, NOx, and SOx emissions can be reduced by replacing a portion of coal with biomass during co-firing The purpose of this article is to review major policies that have promoted biomass co-firing around the world Furthermore, this article investigates the existing co-firing plants with technologies and availability of biomass resources in different countries of the world Finally, this paper summarizes the major global biomass co-firing initiatives and the prospects of biomass co-firing in securing renewable energy target

Bioinspired leaves-on-branchlet hybrid carbon nanostructure for supercapacitors

Abstract: Designing electrodes in a highly ordered structure simultaneously with appropriate orientation, outstanding mechanical robustness, and high electrical conductivity to achieve excellent electrochemical performance remains a daunting challenge. Inspired by the phenomenon in nature that leaves significantly increase exposed tree surface area to absorb carbon dioxide (like ions) from the environments (like electrolyte) for photosynthesis, we report a design of micro-conduits in a bioinspired leaves-on-branchlet structure consisting of carbon nanotube arrays serving as branchlets and graphene petals as leaves for such electrodes. The hierarchical all-carbon micro-conduit electrodes with hollow channels exhibit high areal capacitance of 2.35 F cm-2 (~500 F g-1 based on active material mass), high rate capability and outstanding cyclic stability (capacitance retention of ~95% over 10,000 cycles). Furthermore, Nernst-Planck-Poisson calculations elucidate the underlying mechanism of charge transfer and storage governed by sharp graphene petal edges, and thus provides insights into their outstanding electrochemical performance.
