sQTLs Colocalize with Trait Associations.
(A) Overall summary of the colocalization of sQTLs with mQTLs and pQTLs.
(B) Pathway of degradation from arginine to agmatine. The derived conjugate Fer-Agm is further modified into N-Fer, N-methoxy-Agm. ADC, arginine decarboxylase; PHT, putrescine:hydroxycinnamoyltransferase. A cis-sQTL (rs#chr7.S_169266411) detected at GRMZM2G014295, which encodes a methyltransferase, colocalized with mQTL for the content of Fer-Agm (rs#chr7.S_169265854) and N-Fer, N-methoxy-Agm (rs#chr7.S_169265857). Transcripts named “T” stand for known transcript.
