*Reads from resting urediospores and water‐germinated spores.

^aRatio of haustorial (h) to pre‐haustorial (p) reads normalized by the ‘biological process’ totals.

^b q value near 0 (<10⁻⁵⁰⁰), ratio >4; apparent redundancies and artificially increased categories were removed.

^cProbability values from Fisher's test with correction for multiple testing.

^dBiological process was added to the table as reference to the totals.
