Transcriptomic analysis of the interaction between Helianthus annuus and its obligate parasite Plasmopara halstedii shows single nucleotide polymorphisms in CRN sequences

Table 2 Inter and Intra-racial polymorphisms for 4 putative CRN observed on four P.halstedii races (100, 304, 703, and 710)

Frequencies for each allele for each race are indicated. The khi-2 calculations refer to H0: similar frequencies between races at each position (df = 3, *: significative at 5%; **: significative at 1%; ***: significative at 0.1%).
