Mendelian and Non-Mendelian Regulation of Gene Expression in Maize

eQTL with CNV/PAV nearby and the influence of CNV/PAV on transcriptome variation.
(A) The proportion of genes with cis-eQTL detected. Genes located within/near structural variants are enriched for cis-eQTLs, especially for genes entirely within CNV/PAV. (B) The expression distribution in the RILs of gene GRMZM2G016150, which is entirely a CNV event, is positively correlated (P = 3.7E-46) to increased copy number at this locus in the RILs. (C) The expression distribution in the RILs of gene GRMZM2G024775, which exhibits a gain of a copy in B73 and lines containing the B73 allele, shows a negative correlation (P = 6.3E-61) between the gain of a copy in B73 and the lower copies in Mo17. In (B) and (C), the x-axis represents the genotype of RILs for the specific gene, while the y-axis indicates the normalized expression levels in the RILs and their parents.
