Abstract

|
|
Contour-clamped homogeneous electric field gel electrophoresis was used to establish electrophoretic karyotype for 10 species of Fusarium sections Sporotrichiella, Liseola, Gibbosum, Discolor and Martiella. Intact chromosomal DNA was isolated from fungal protoplast and separated under various conditions according to their size in order to improve DNA separation. The numbers of chromosome-sized DNA molecules for individual species ranged from 5-13, with individual chromosomes ranging from 0.78 Mb to 7.20 Mb in size. The total genome DNA size of each species was estimated at about 18.32 Mb to 48.20 Mb. Comparison of karyotype profiles following Southern hybridization analysis with a randomly selected genomic probe of F. oxysporum formae speciales lilii was carried out.
