Abstract
An estimate has been made of the amount of sequence homology present in the chloroplast DNA (ctDNA) of several higher plants by the technique of DNA-DNA hybridization. Approximately 85% of tomato, 60% of spinach, 45% of kale, and 15% of barley ctDNA sequences were found to hybridize with tobacco ctDNA under conditions in which maximum hybridization in homologous reactions reached 85%. All heteroduplexes contained significant amounts of sequence mismatch as indicated by a 3 to 9 C decrease in melting temperature as compared to homoduplex.This publication has 21 references indexed in Scilit:
