C. graminicola strain M1.001

C. graminicola strain M1.001 (also known as M2) was collected in Missouri in the late 1970s from infected maize (Forgey et al. 1978). This strain was selected for sequencing at Broad because it is the most commonly used lab strain, and it is easily manipulated genetically. This strain is very aggressive on both maize leaves and stalks. It can be transformed, and crosses as both a male and a female with most other field strains tested (Vaillancourt and Hanau, 1991).

C. graminicola strain M5.001

C. graminicola strain M5.001 was collected from infected maize in Brazil in the late 1980s by Dr. H.P. da Silva. The genome of this strain was sequenced to about 1X coverage by a research team at DuPont Nemours Inc. The sequence data were generously donated to the public by DuPont in 2008. M5.001 is similar to M1.001 in its level of aggressiveness to maize leaves and stalks, and it can also be transformed relatively easily. It is fertile as both a male and female in crosses with M1.001 (Vaillancourt and Hanau, 1991).

C. higginsianum strain IMI 349063

The C. higginsianum isolate selected for sequencing is IMI 349063 from the CABI Culture Collection, which was originally isolated from Brassica rapa (pak-choi) in Trinidad. This isolate was chosen because a wealth of genomic resources was already available for this genotype, including large EST collections, proteomic data and random insertional mutants. This isolate appears to be asexual (O'Connell et al., 2004).
