“…However, sequences of ITS regions were apparently distinguished from one another among species of the genus Meira. In addition, M. geulakonigii and M. argovae were isolated only from cadavers of dead mites and speculated to be acaropathogenic fungi (Boekhout et al 2003;Sztejnberg et al 2004). More studies are necessary to reveal the relationship between the present new species and mites in orchards in view of a potential acaropathogenic fungus.…”

“…The genus Meira was proposed by Boekhout et al (2003) as novel basidiomycetous, anamorphic yeastlike fungi as well as the genus Acaromyces. The genus Meira includes two species to date, and the type species is M. geulakonigii Boekhout, Scorzetti, Gerson & Sztejnberg. Meira geulakonigii and another species, M. argovae Boekhout, Scorzetti, Gerson & Sztejnberg, were isolated only from cadavers of mites collected in Israel and speculated to be acaropathogenic fungi (Boekhout et al 2003;Sztejnberg et al 2004) such as Hirsutella thompsonii F.E. Fisher and Neozygites floridana (Weiser & Muma) Remaud.…”

Meira nashicola sp. nov., a novel basidiomycetous, anamorphic yeastlike fungus isolated from Japanese pear fruit with reddish stain Abstract Three undescribed strains of basidiomycetous, anamorphic yeastlike fungi were isolated from Japanese pear fruits with a reddish stain collected in Tottori Prefecture, Japan. The strains are classified in a single group and assigned to the genus Meira by conventional and chemotaxonomic studies. Sequence analyses of the D1/D2 domain of 26S rDNA and internal transcribed spacer (ITS) regions indicate that the strains represent a novel species with a close phylogenetic relationship to Meira geulakonigii and M. argovae. The name Meira nashicola sp. nov. is proposed for the strains (type strain PFS 002 = MAFF 230028 = CBS 117161).

A tale of three acaropathogenic fungi in Israel: Hirsutella, Meira and Acaromyces

et al. 2008

We review published and unpublished studies conducted in Israel with six acaropathogenic fungi, assayed in order to control the citrus rust mite, Phyllocoptruta oleivora (Ashmead) (CRM). Hirsutella thompsonii Fisher was introduced twice, killed 80-90% of the exposed mites, but due to its requirements for near-saturation humidities was deemed unsuitable for local outdoors conditions. Hirsutella kirchneri (Rostrup) Minter et al. and Hirsutella necatrix Minter et al. were also introduced and assayed against CRM and spider mites, but their efficacy was unsatisfactory. Three indigenous fungi found to be associated with mites, Meira geulakonigii, Meira argovae and Acaromyces ingoldii--all three recently described by Boekhout, Gerson, Scorzetti & Sztejnberg--were assayed against several mites. Meira geulakonigii killed 80-90% of several spider mites and of the CRM, and caused some mortality of Iphiseius degenerans (Berlese), one out of three phytoseiid predators assayed. Mortality was not due to parasitization; extracts from the media in which the fungi had developed caused considerable mite death, suggesting that it was a result of fungal toxins. Data from a field study indicated that spraying blastoconidia of M. geulakonigii on grapefruits infested by CRM significantly reduced pest-incurred damage from 23 to 13%. Applying qRT-PCR methodology indicated that M. geulakonigii was endophytic within sealed grapefruit flowers and in the flavedo of the fruits' peel. Neither in the laboratory nor in the field was any evidence ever obtained that this fungus damaged the plants, leading us to hypothesize that M. geulakonigii serves as a "body guard" of grapefruits (and perhaps other plants as well). All three fungi suffered very little mortality after being exposed to various insecticides and acaricides that are in current local use (with the exception of sulfur). The ability of M. geulakonigii to reduce mite numbers without affecting the host plant, the minimal fungal effect on some predatory mites, its endophytic nature along with the apparent tolerance of M. geulakonigii to many insecticides and acaricides, suggest that this fungus could be suitable for integrated pest management (IPM) program.

“…et al 2007a;Yasuda et al 2007), and M. nashicola from pear fruit (Yasuda et al 2006). However, Meira species were originally reported as mite parasites (Boekhout et al 2003;Sztejnberg et al 2004;Paz et al 2007b). In view of these facts, the mite-associated phase of Meira species probably derived from a plant-parasitic life cycle.…”

Isolation of basidiomycetous anamorphic yeast-like fungus Meira argovae found on Japanese bamboo

et al. 2008

View full text Add to dashboard Cite

A basidiomycetous anamorphic yeast-like fungus, isolated from new bamboo shoots collected in Japan, was assigned to Meira argovae by comparison of conidial morphology, physiological characteristics, rDNA sequences, and DNA-DNA relatedness with the ex-type strains of Meira species. This is the fi rst record of the fi nding of M. argovae from other than mite cadavers and in regions other than Israel. Phylogenetic analysis based on the D1-D2 domain demonstrated that Meira species and teleomorphic Dicellomyces species, which include a bamboo leaf parasite, D. gloeosporus, formed sister clades.
