Abstract
The nuclear (n) and mitochondrial (mt) genomes of the take-all fungus were examinned by reassociation kinetics with Escherichia coli DNA as internal standard. Only 1 kinetic component was detected in each DNA, with 2nd-order rate constants of 0.022 M-1 s-1 for nDNA and 10.9 M-1 s-1 for mtDNA, corresponding to sequence complexities of 29 .times. 106 base pairs and 60 .times. 103 base pairs, respectively.
