Rapid generation of chromosome-specific alphoid DNA probes using the polymerase chain reaction [PDF]

open access: yes, 1992
Non-isotopic in situ hybridization of chromosome-specific alphoid DNA probes has become a potent tool in the study of numerical aberrations of specific human chromosomes at all stages of the cell cycle. In this paper, we describe approaches for the rapid

DNA amplified fingerprinting, a useful tool for determination of genetic origin and diversity analysis in Citrus [PDF]

open access: yes, 1995
We used three short repetitive nucleotide sequences [(GTG)5, (TAC)5, and (GACA)4] either as radiolabeled probes for hybridization with restricted Citrus DNA or as single primers in polymerase chain reaction amplification experiments with total genomic ...

Optimization of ISSR-PCR reaction system and selection of primers in Bryum argenteum

open access: yes上海师范大学学报. 自然科学版, 2017
In order to determine optimum ISSR-PCR reaction system for moss Bryum argenteum,the concentrations of template DNA primers,dNTPs,Mg2+ and Taq DNA polymerase were optimized in four levels by PCR orthogonal experimental method. The appropriate primers were

An efficient method for DNA extraction from Cladosporioid fungi [PDF]

open access: yes, 2010
We developed an efficient method for DNA extraction from Cladosporioid fungi, which are important fungal plant pathogens. The cell wall of Cladosporioid fungi is often melanized, which makes it difficult to extract DNA from their cells.

Chloroplast-specific universal primers and their uses in plant studies

open access: yesBiologia Plantarum, 2011
Universal (consensus) primers are those primers that have the ability to amplify the targeted region of DNA across a broad range of individuals in a certain group of organisms. In plants, such universal primers have been designed to target regions in the
