This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: The following leafhoppers (Deltocephalinae: Bonaspeiini) of the Fynbos Biome of South Africa are treated: Colistra parvulus (Linnavuori, 1961) is redescribed and three new species of Colistra Davies are described, i.e., C. acapitatus sp. n., C. bucapitatus sp. n. and C. semialius sp. n.; four species of Proekoides Stiller, 1986 are reviewed with the addition of P. postspina sp. n.; Proekes cephaleus (Naudé, 1926) is redescribed with details of the female ovipositor, and three new species, i.e., P. hemiplatyphalis sp. n., P. tetracaphalis sp. n., P. diacaphalis sp. n.; a new genus, Xhoreus gen. n. is described with one new species, X. ulosentus sp. n. All species are of similar appearance, size and with reduced hind wings. Two species, C. acapitatus and C. bucapitatus, were collected on Rooibos tea. Keys are provided to species of Colistra, Proekes and Proekoides. Distribution models show limited ranges in the Western Cape province and confined to the Fynbos Biome while Xhoreus ulosentus is possibly endemic to the Cape Peninsula. The validity of the tribe Bonaspeiini is discussed. Keywords: Afrotropical Region, biodiversity, Cape Floristic Region, herbivore, phytophagous, plant-feeding, Rooibos tea, shrub-association, Western Cape province, Succulent Karoo Biome, Savanna Biome"--Page 3.

Available in PDF, EPUB and Kindle. Book excerpt: The practical need to partition the world of viruses into distinguishable, universally agreed upon entities is the ultimate justification for developing a virus classification system. Since 1971, the International Committee on Taxonomy of Viruses (ICTV) operating on behalf of the world community of virologists has taken on the task of developing a single, universal taxonomic scheme for all viruses infecting animals (vertebrate, invertebrates, and protozoa), plants (higher plants and algae), fungi, bacteria, and archaea. The current report builds on the accumulated taxonomic construction of the eight previous reports dating back to 1971 and records the proceedings of the Committee since publication of the last report in 2005. Representing the work of more than 500 virologists worldwide, this report is the authoritative reference for virus organization, distinction, and structure.

Download or read book Potato Biology and Biotechnology written by Dick Vreugdenhil and published by Elsevier. This book was released on 2011-08-31 with total page 857 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past 15-20 years major discoveries have been concluded on potato biology and biotechnology. Important new tools have been developed in the area of molecular genetics, and our understanding of potato physiology has been revolutionized due to amenability of the potato to genetic transformation. This technology has impacted our understanding of the molecular basis of plant-pathogen interaction and has also opened new opportunities for the use of the potato in a variety of non-food biotechnological purposes. This book covers the potato world market as it expands further into the new millennium. Authors stress the overriding need for stable yields to eliminate human hunger and poverty, while considering solutions to enhance global production and distribution. It comprehensively describes genetics and genetic resources, plant growth and development, response to the environment, tuber quality, pests and diseases, biotechnology and crop management. Potato Biology is the most valuable reference available for all professionals involved in the potato industry, plant biologists and agronomists. Offers an understanding of the social, economic and market factors that influence production and distribution Discusses developments and useful traits in transgenic biology and genetic engineering The first reference entirely devoted to understanding new advances in potato biology and biotechnology
