named in honor of Eric Bish (1967–2000), who was a strawberry specialist in the Dept. of Horticulture-NCSU and valued collaborator on the strawberry diseases project (Dept. of Plant Pathology-NCSU)
Type: UNITED STATES OF AMERICA, North Carolina, Raleigh, from roots of strawberry (Fragraria x ananassa) in greenhouse, 16 Nov 1999, collector Z.G. Abad, BPI 878369 in Herbarium (dried culture on baby carrot agar from isolate Cg 2.3.3)
Ex-type: CBS 122081
Sequences for ex-type in original manuscript: Phytophthora bisheria isolate Cg.2.3.3 = ITS rDNA: AY241924

- Phytophthora DATABASE: Phytophthora bisheria P10117 not available. Originally, PD had the extype Cg 2.3.3 WPC P10117 ITS FJ801281, TEF WPC P10117 PD-00066 EU080743, EU080742 WPC P10117 PD-00066, but this information has been removed (search on 7/12/13). Isolates P1620 (PD_00051) with different genes in PD and CBS 114090 = P1621 = Benson 412 with ITSrDNA and CoxI do not correspond to P. bisheria. They correspond to Phytophthora taxon pseudobisheria in progress by Z.G. Abad.
- EPPO-Q-bank: Phytophthora bisheria representative strain CBS 114090 = P1621 = Benson 412 (corresponds to P. taxon pseudobisheria G. Abad in progress). Other strain CBS 122081 is correct.
Position in ITS phylogenetic tree
Colonies and cardinal temperatures
Colonies on potato dextrose agar and malt extract agar with no distinct pattern, on V8 agar with slow growth. Minimum temperature for growth is 10°C, optimum 26°C, and maximum 32°C.
Conditions for growth and sporulation
Sporangia semipapillate, some bipapillate; persistent; ovoid, obpyriform, ovoid-obpyriform, obturbinate, globose (23 µm diam), or irregular and usually have a tapered base; a large vacuole is observed in many sporangia; sporangia are originated by direct germination of primary sporangia or individually in long unbranched sporangiophores. Sporangiophores may have hyphal swellings. Hyphal swellings sometimes present with coraloid nodose irregular shapes and hairy projections. Chlamydospores absent.
Homothallic. Oogonia smooth-walled but sometimes producing irregular projections, spherical 24–46 (av. 35) µm diameter, terminal, rarely intercalary. Antheridia paragynous with broad attachment to the oogonial wall 7–11 (av. 9.5) µm, frequently with long stalk and branched. Occasionally two or three antheridia per oogonium are observed. Oospores aplerotic, rarely plerotic, 25–31 (av. 28) µm diameter, wall 4–6 (av. 5) µm thick.
Most typical characters
Hosts and distribution
Distribution: North Carolina, USA; Netherlands; Knoxfield, Australia
Substrate: roots of strawberry, roots of young rose cuttings, roots of raspberry
Disease note: Symptoms include slight yellowing and root rot. Infected cuttings are stunted, have fewer side shoots, and smaller dull green leaves that yellow and shed prematurely. Newly formed roots are rotted.
Hosts: Phytophthora bisheria has been recovered from Fragaria X ananassa (strawberry) roots in North Carolina, USA, rose in the Netherlands, and Rubus idaeus (raspberry) in Australia.
