^aGO term classifications: P, Biological Process; C, Cellular Component; F, Molecular Function.
^bQuery item number in MS preferential expressed genes.
^cTotal annotated query item number in agriGO.
^dQuery item number in maize genome version 5a.
^eTotal annotated item number in maize genome version 5a.
^fDetermined by Fisher exact test.
^gDetermined by Benjamini–Hochberg–Yekutieli procedure.
GO terms with P-value < 0.001 and FDR ≤ 0.05 were regarded as overrepresented terms.
