Hormone metabolism GRMZM2G446858 Carotenoid cleavage dioxygenase AT4G32810a,b,c CCD8, MAX4 Carotenoid cleavage dioxygenase 8 ++ ++ ++ AT4G32810a,b,c ZmCCD8/MAX4 is a stringolactone biosynthetic gene of which the knockout mutant shows a branching phenotype, comparable to the Arabidopsis orthologous mutant, and in addition shorter stature and smaller ears [124, 155]
Protein degradation GRMZM2G704093   AT5G46210a,b CUL4 Cullin4 −− −− AT5G46210a,b CUL4 is part of an E3 ubiquitin ligase complex. Loss of function mutants display reduced growth and aberrant leaf phenotypes [127]

GRMZM2G091715 Acyl carrier protein AT4G25050c ACP4, ACP1, ACP2, ACP3, ACP5 Acyl carrier protein ++ ++ ++ AT4G25050c Reduced ACP4 levels result in a decreased lipid content and varying degrees of a bleached phenotype, smaller size and shorter bolts [122]

Development GRMZM2G170567   AT5G18410a,b KLK, PIR, PIR121, PIRP, SRA1 Transcription activators −− −− AT5G18410a,b Downregulation results in larger rosettes that are epinastic and paler green, next to additional developmental phenotypes [126]
RNA processing GRMZM2G346639   AT5G53770a,b,c   Nucleotidyl-transferase family protein −− −− −− AT5G53770a,b,c T-DNA line shows smaller, more compact rosette with more roundish leaves [77]
Unknown GRMZM2G406043   AT3G04490a,c    −− −− −− AT3G04490a,c Smaller rosette size due to smaller leaves in T-DNA line [77]

Double plus signs ("++") indicate transcript levels positively correlated with phenotypic trait (q0.99). Single plus signs ("+") indicate transcript levels positively correlated with phenotypic trait (qrandom). Double minus signs ("−−") indicate transcript levels negatively correlated with phenotypic trait (q0.01). Single minus signs ("") indicate transcript levels negatively correlated with phenotypic trait (qrandom)
