Serological and molecular approaches for distinguishing bean common mosaic and bean common mosaic necrosis potyviruses and their respective pathogroups

Creator:: Xu, Ling, 1963-
Abstract:: Polyclonal antisera were raised against isolates of bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV) using conventional serological methods. Infected tissues containing, respectively, 22 recognized BCMV and BCMNV isolates were tested against the two antisera by antigen-coated plate (ACP) ELISA and double antibody sandwich (DAS) ELISA....

Biology of chlamydospores of Phytophthora ramorum

Creator:: Smith, Aaron Lee
Abstract:: The chlamydospore is a survival spore produced by 35 of the 75 described species of Phytophthora. Phytophthora ramorum Werres, de Cock & Man in't Veld, the causal agent of Sudden Oak Death (SOD), produces abundant chlamydospores in artificial culture and plant tissue. The chlamydospore is likely the most important survival...

Light-induced absorbance changes and partial reactions of photosynthesis in mutants of Scenedesmus obliquus, strain D₃

Creator:: Pratt, Lee Herbert
Abstract:: Partial reactions of photosynthesis were examined in the wild type strain and six photosynthetic mutants (8, 11, 26, 40, 50, a') of Scenedesmus obliquus, strain D₃. A reproducible procedure for the isolation of active chloroplast fragments from Scenedesmus was developed. Several chloroplast reactions were examined, as well as two in...

Comparative wood anatomy of the Fagaceae of Taiwan

Creator:: Lee, Chun-shu
Abstract:: Many species of the Fagaceae have been variously interpreted on the basis, primarily of external morphological characteristics. The objectives of this study are to elucidate generic and specific characteristics of the wood of Fagaceae and to attempt to obtain evidence regarding taxonomic relationships among some of the species occurring in...

A biosystematic study in the genus Aster, section Aster, in western North America

Creator:: Dean, Milton Lee
Abstract:: A biosystematic investigation was undertaken in 15 species and three subspecies of the genus Aster, in western North America. Previous studies had been based entirely on external morphological features, and it was believed that much could be learned about the natural affinities of the taxa by exploring their cytological and...

Cytokinin O-glycosyltransferases : biochemical characteristics in vitro and developmental regulation in transgenic plants

Creator:: Veach, Yeonjin Kim
Abstract:: Cytokinins are plant hormones regulating cell division and differentiation. Most developmental events from germination, vegetative morphogenesis to seed and fruit set are influenced by cytokinins. t,ns-Zeatin is the major natural occurring cytokinin. Its isomer, cis-zeatin, and its derivatives are usually present in low quantities and have traditionally been considered as...

Effect of iron on biological control of fire blight by Pseudomonas fluorescens A506

Creator:: Temple, Todd N.
Abstract:: Competitive exclusion has been the mechanism hypothesized to account for the biological control of fire blight disease of pear and apple by the bacterium Pseudomonas fluorescens A506 (A506). Recent laboratory assays demonstrated, however, that A506 produces an antibiotic that is toxic to the fire blight pathogen, Erwinia amylovora, when cultured...

Enhancement of thiamin in plants by metabolic engineering

Creator:: Dong, Wei, Stockwell, Virginia O., and Goyer, Aymeric
Abstract:: Thiamin is an essential nutrient in the human diet. Severe thiamin deficiency leads to beriberi, a lethal disease which is common in developing countries. Thiamin biofortification of staple food crops is a possible strategy to alleviate thiamin deficiency-related diseases. In plants, thiamin plays a role in the response to abiotic...
