对85个双核类立枯丝核菌菌株的菌丝融合进行了研究。在配对的基础上，发现了7个吻合组（CAG），并将其指定为CAG 1至CAG 7。分离株（71株）归属于7个CAG。从7个CAG菌株中随机选取54个菌株与R. solani AG 1、2、3或4。在每个CAG有很少的同质性，以主机，植物部分入侵和地理起源，与CAG 1分离物，这是唯一与成员的禾本科。CAG 2包括R. ramicola和R.草莓。其中4株经诱导产孢后鉴定为C.角草。CAG 6包括一个R. muneratii。CAG 1、2和7中的大多数菌株中没有深色菌丝和菌核色素沉着是将这些组中的菌株与其他融合组中的菌株以及R.索拉尼CAG 3、4和5菌株产生的黑色菌丝和菌核色素与R.索拉尼的吻合组的生物学和分类学意义进行了讨论。
Hyphal anastomosis was studied among 85 isolates of binucleate Rhizoctonia solani-like fungi. On the basis of pairings, 7 anastomosis groups (CAG) were discovered and designated CAG 1 through CAG 7. Isolates (71) were assigned to the 7 CAG. No hyphal fusion occurred in pairings between 54 isolates, randomly selected from the 7 CAG and isolates of R. solani AG 1, 2, 3 or 4. Within each CAG there was little homogeneity as to host, plant part invaded and geographic origin, with the exception of CAG 1 isolates, which were associated only with members of the Gramineae. CAG 2 included isolates of R. ramicola and R. fragariae. Four isolates in this group were induced to sporulate and were identified as C. cornigerum. CAG 6 included an isolate of R. muneratii. The absence of dark mycelial and sclerotial pigmentation among the majority of isolates in CAG 1, 2 and 7 was the significant cultural feature distinguishing isolates in these groups from isolates in other anastomosis groups and from isolates of R. solani. Isolates in CAG 3, 4 and 5 formed dark mycelial and sclerotial pigments similar to those produced by isolates of R. solani. The biologic and taxonomic implications of the anastomosis groups are discussed.
