| oligonucleotide fingerprinting detects genetic diversity among ascochyta rabiei isolates from a single chickpea field in tunisia. | fifty isolates of ascochyta rabiei (pass.) labr. were hierarchically sampled from four well-separated locations of a single chickpea field in beja (tunisia), and single-spored. dna was isolated from in-vitro-grown mycelia, digested with hinfi or rsai, and hybridized to a set of synthetic oligonucleotides complementary to simple repetitive sequences. according to the fingerprint patterns derived from the probes (ca)8, (caa)5, (cat)5 and (gata)4, 12 different fungal haplotypes were found at variou ... | 1994 | 7859300 |
