¹Overrepresentation of GO Slim terms was calculated using hypergeometric distribution followed by a modified Bonfferoni correction for multiple testing as implemented in GeneMerge [72], where the e-score is comparable to a P-value. Overrepresented GO terms were those with e-scores < 0.05.
²Each phase group was analyzed separately to identify GO terms overrepresented at a specific phase.
