Abstract An increasing number of plant viruses and viroids have been reported from all over the world due largely to metavirogenomics approaches with technological innovation. Herein, official changes virus taxonomy, including establishment megataxonomy amendments codes classification nomenclature, recently made by International Committee on Taxonomy Viruses were summarized. The continued effor...

Most known insect species are involved in chemically mediated plant–insect multi-trophic interactions, and recent syntheses point to a substantial gap in our understanding of trophic interaction diversity, especially in the tropics. One approach to filling this gap is to examine relationships between genomic, metabolomic, taxonomic, and trophic interaction diversity via quantifying and comparin...

In continuation of our search for biologically active molecules from terrestrial sources, we have investigated the creeping perennial herb Phyla nodiyora (Linn) Greene (Verbenaceae) ("Lippia nodiyora (Linn.) Mich), which grows widely in India. The leaves of P. nodiyora were collected from Bhadrachalam forest in October 1998. The plant was identi"ed by Prof. M. Prabhakar, Plant Anatomy and Taxon...

In the beginning of modern plant biology, plant biologists followed a simple model for their science. This model included important branches of plant biology known then. Of course, plants had to be identified and classified first. Thus, there was much work on taxonomy, genetics, and physiology. Ecology and evolution were approached implicitly, rather than explicitly, through paleobotany, taxono...

Plants are the primary source of medicine for most of the world. The most fundamental step in the scientific study of medicinal plants is establishing their botanical identity. Many studies lack voucher specimens, which serve as permanent records of scientific investigations. This omission makes positive identification impossible and hinders reproducibility. Even when vouchers are cited, scient...

Sixteen isolates of Colletotrichum were collected from leaves with anthracnose symptoms or leaf spots of twelve wild, cultivated and ornamental plant species from the Guilan, Mazandaran, and Golestan provinces in Northern Iran. Five different species, including C. aenigma, C. gigasporum, C. godetiae, C. karstii, and C. musae were identified based on the DNA sequence data (TUB2, GS, GAPDH). Four...

Stable isotope analysis of primate tissues in tropical forest contexts is an increasingly popular means of obtaining information about niche distinctions among sympatric species, including preferences in feeding height, forest canopy density, plant parts, and trophism. However, issues of equifinality mean that feeding height, canopy density, as well as the plant parts and plant species consumed...
