Development and characterization of new microsatellites for walnut (Juglans regia).
The expressed sequence tag (EST) database represents a potentially valuable resource for the development of simple sequence repeat (SSR) markers for use in evolutionary studies. EST-SSRs reveal polymorphisms not only within the source taxon, but in related taxa as well. In this paper, we describe a case study in which the publicly available walnut (Juglans regia) EST database was used to develo...
متن کاملIsolation and characterization of 20 polymorphic microsatellite markers for Juglans mandshurica (Juglandaceae)1
UNLABELLED PREMISE OF THE STUDY Fifty microsatellite loci were developed for the endangered species Juglans mandshurica to investigate its genetic diversity and population structure. • METHODS AND RESULTS In all, 50 microsatellite markers were isolated from J. mandshurica, using the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) protocol. Twenty of these polymorphic marker...
متن کاملInvolvement of peroxidases in the formation of the brown coloration of heartwood in Juglans nigra.
Oxidase activities were investigated within the cross-section of walnut trunk in relation to the brown staining of heartwood, especially in the transition zone where the colour change occurs. The distribution of peroxidase activity was investigated using 3,3'-diaminobenzidine (DAB) or guaiacol as a substrate. Generally, the highest activity was found in the cambial zone and in the middle sapwoo...
متن کاملConcentration Levels of Imidacloprid and Dinotefuran in Five Tissue Types of Black Walnut, Juglans nigra
Black walnut, a valuable economic and environmentally important species, is threatened by thousand cankers disease. Systemic imidacloprid and dinotefuran applications were made to mature black walnut trees to evaluate their translocation and concentration levels in various tissue types including leaf, twig, trunk core, nutmeat, and walnut husk. The metabolism of imidacloprid in plants produces ...
متن کاملGenetic instability of microsatellites in endometrial carcinoma.
Hereditary nonpolyposis colorectal cancer (HNPCC) is characterized by a familial predisposition to colorectal carcinoma and extracolonic cancers of the gastrointestinal, urological, and female reproductive tracts, notably the endometrium. A genetic locus for HPNCC was recently determined by linkage analysis to exist on chromosome 2p; both sporadic and HNPCC-associated colorectal carcinomas exhi...
