Four practical examples in comparing the expression patterns between maize genes and FSR1, one of the selected pathogenicity genes of F. verticillioides. Y-axis corresponds to the normalized expression level and X-axis corresponds to the replicate ID (replicates 1-6: 3 dpi, replicates 7-12: 6 dpi, replicates 13-18: 9 dpi). Four different cases are illustrated: A) FSR1 vs. GRMZM2G082899 T01 (cointegration: good, correlation: good, expression: good) - GRMZM2G082899 T01 was considered as a good corresponding maize gene to FSR1 ; B) FSR1 vs. GRMZM2G027166 T03 (cointegration: good, correlation: bad, expression: good) - the association between the two genes turned out to be weak based on correlation; C) FSR1 vs. GRMZM2G152029 T01 (cointegration: bad, correlation: good, expression: good) - the time-course expression trends were dissimilar for the two genes, reflected in low cointegration; D) FSR1 vs. GRMZM2G405655 T01 (cointegration: good, correlation: good, expression: bad): GRMZM2G405655 T01 gene was not considered to be a good candidate, since it was hardly expressed.
