Identification of Armillaria species from Hokkaido by analysis of the intergenic spacer (IGS) region of ribosomal DNA using PCR-RFLP

et al. 1998

The intergenic spacer (IGS) region, which is located between the 3' end of 26S ribosomal DNA (rDNA) and the 5' end of 5S rDNA, of six Armillaria species from Hokkaido was investigated using polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP). Restriction with only Alu I could distinguish A. mellea subsp, nipponica from the other species. With Alu I and Dde I, A. ostoyae and A. gallica could be distinguished from the other species. Digestion with Alu I resulted in two patterns (types A and B) of A. singula and three patterns (types A, B, and C) of A.[ezoensis. One pattern (type B) of the former species and two patterns (types B and C) of the latter species were each different from those of the other species. Armillaria sinapina gave only one Alu I digestion pattern, which was identical to that of A. jezoensis (type A) and A. singula (type A). However, by digestion with Dde I, A. singula (type A) could be distinguished from A. jezoensis (type A) and A. sinapina.

“…Somatic incompatibility has been used to distinguish isolates of African Armillaria (Abomo-Ndongo and Guillaumin 1997). However, most attempts to characterize these have tended to employ methods that do not depend on the presence of basidiomata or haploid forms; e.g., techniques based on the use of isozyme electrophoresis (Mwangi et al 1989, Agustian et al 1994, Mwenje and Ride 1996, molecular markers such as DNA restriction fragment polymorphisms (Anderson et al 1987, Smith andAnderson 1989), RAPD (Mohammed 1994), nuclear DNA-DNA homology ( Jahnke et al 1987), and DNA sequence analysis (Anderson and Stasovski 1992). Analysis of the ribosomal DNA spacers, ITS and IGS, from Armillaria isolates collected from various geographical areas in tropical Africa discriminated A. mellea, A. heimii and a possible new species (Chillalli et al 1997).…”

Abstract:Armillaria is a primary root rot pathogen of tea (Camellia sinensis) in Kenya. The main species presently described in this country are A. mellea and A. heimii. A survey covering fourteen districts of Kenya was carried out and forty-seven isolates of Armillaria collected. Cultural morphology, rhizomorph characteristics, somatic incompatibility and features of basidiomata were used to characterize the isolates, together with molecular analysis based on randomly amplified polymorphic DNA (RAPD), inter-simple sequence repeat (ISSR), restriction fragment length polymorphism (RFLP) of the internal transcribed spacer (ITS) and the intergenic spacer (IGS) regions and sequence of the IGS region. It can be concluded that two Armillaria species were present and they were different from A. mellea. The first group was morphologically similar to A. heimii but this was contradicted by the molecular data, suggesting that A. heimii could be a complex of several species. The second group was different from the first and morphological and molecular data strongly suggest that it could be a new Armillaria species.
