“…Sporidiobolus ruineniae was first found in Indonesia (Holzschu et al, 1981;Phaff, 1970;Ruinen, 1963). It was isolated from 2.4 and 17.5% of plants collected in Thailand (Table 5), but not in the Temperate Zone (Tables 1-3, 6).…”

“…The enzymes of these two species have similar electrophoretic patterns except for MDH and G6PDH, and their assimilation patterns of carbon compounds and potassium nitrate are also similar. Moreover, Sporidiobolus johnsonii YK 457 was similar to the S. salmonicolor group with respect to its FA, 6PGDH, Fma, G6PDH, HK, GDH, and Cat pattern Sporidiobolus johnsonii and the S. salmonicolor group exhibited similar G+C contents of DNAs (9,32). As far as this study is concerned, Sporidiobolus johnsonii seems to be closely related to the S. salmonicolor group.…”

“…According to HoLZSCHU et al (32), these two species differed by 1.2 mol % G+C in the base composition of their nuclear DNAs and shared only about 8.5 % of their nuclear DNA base sequences. Therefore, Sporidiobolus ruinenii seems to be a species distinct from Sporidiobolus johnsonii.…”

The patterns produced by nine enzymes of ballistosporogenous yeasts and supposedly related yeasts were studied by electrophoresis on polyacrylamide gel. Forty-two strains belonged to the genera Sporobolomyces, Sporidiobolus, Aessosporon and Bullera and twenty-four strains to Rhodotorula, Rhodosporidium, Cryptococcus, unidentified ballistosporogenous yeasts, and Candida edax. Four Sporobolomyces salmonicolor strains, two Sporobolomyces holsaticus strains, two Sporobolomyces odorus strains, five Sporidiobolus salmonicolor strains, two Aessosporon salmonicolor strains, and one strain of Aessosporon dendrophilum produced similar electrophoretic patterns. Moreover, mating was observed between some of these strains. Sporobolomyces roseus and Sporobolomyces shibatanus differed from Sporobolomyces salmonicolor in their glucose-6-phosphate dehydrogenase (EC 1.1.1.49.), but the patterns of the other enzymes were similar; all three species differed clearly from Sporobolomyces singularis, Sporobolomyces gracilis, Sporobolomyces puniceus, and Sporobolomyces antarcticus. Sporobolomyces albo-rubescens showed a peculiar 6-phosphogluconate dehydrogenase (EC 1.1.1.41.) pattern and was similar to two Rhodotorula rubra strains in the pattern of their enzymes. Close relationships were also seen between Sporidiobolus ruinenii and Rhodotorula graminis, and between Bullera alba and a strain in Cryptococcus albidus var. albidus in the electrophoretic patterns of their enzymes. Four unidentified strains which had lost the ability to produce ballistospores had patterns similar to those of Bullera alba, Rhodotorula glutinis, Cryptococcus laurentii var. flavescens, and Cryptococcus macerans. Three colorless strains, putatively derived from a strain of Sporobolomyces roseus, showed the same electrophoretic patterns as the strains from which they originated.

“…It was noted that the two species had similar nutritional patterns (Fell and Tallman 1981) but differed in nuclear and mitochondrial DNA mol. % of G+C content (Holzschu et al 1981). Subsequent studies revealed 75.8% similarity in DNA-DNA reassociation experiments involving the type strains of the two species (Boekhout 1991).…”

The relationship between Sporidiobolus johnsonii and S. salmonicolor was investigated using rDNA sequence data. Two statistically well-supported clades were obtained. One clade included the type strain of S. johnsonii and the other included the type strain of S. salmonicolor. However, some mating strains of S. salmonicolor were found in the S. johnsonii group. These strains belonged to mating type A2 and were sexually compatible with mating type A1 strains from the S. salmonicolor group. DNA-DNA reassociation values were high within each clade and moderate between the two clades. In the re-investigation of teliospore germination, we observed that the basidia of S. salmonicolor were two-celled. In S. johnsonii, basidia were not formed and teliospore germination resulted in direct formation of yeast cells. We hypothesize that the S. johnsonii clade is becoming genetically isolated from the S. salmonicolor group and that a speciation process is presently going on. We suspect that the observed sexual compatibility between strains of the S. johnsonii and S. salmonicolor groups and the possible genetic flow between the two species has little biological relevance because distinct phenotypes have been fixed in the two taxa and intermediate (hybrid) sequences for LSU and ITS rDNAs have not been detected.
