Phytoliths in Taxonomy of Phylogenetic Domains of Plants
We discuss, from the aspect of phylogeny, the interrelationships of the phytolith types in plants from the main taxonomical groups (algae, lichens, horsetails, gymnosperms, and floral plants) with homologues of known proteins of biomineralization. Phytolith morphotypes in various phylogenetic plant domains have different shapes. We found that, in ancient types of plants (algae, horsetails, and ...

متن کاملNumerical taxonomy of some yellow-pigmented bacteria isolated from plants.
Phenetic data on over 60 heterotrophic, Gram-negative, yellow chromogenic bacteria from plant material were collected and analysed using numerical taxonomic methods. Marker strains representing 42 taxa were included in the analyses. At similarity levels of 80% or above, eight distinct clusters were obtained, the first four of which included yellow chromogens.

متن کاملISO 14001 certified plants in Brazil ヨ taxonomy and practices
Research on taxonomies has helped in shedding light on similarities between firms in a particular group and differences between each group. However, few studies have analyzed how operations managers of manufacturing firms in emerging countries adopt diverse strategies of environmental management, with diverse operational practices and results. This study fills this gap by proposing a taxonomy f...
