Inheritance pattern of lncRNAs and FGS genes in 105 maize IBM RILs. (A-D) Two-dimensional kernel density estimation of gene expression patterns in RILs compared with the two parents for FGS genes and lncRNAs. The x-axis and y-axis represent the expression-level deviation in 105 RILs to the parents B73 and Mo17, respectively. FGS-High, FGS genes with expression level ≥10 RPKM; lncRNA-High, lncRNAs with expression level ≥10 RPKM. (E) Schematic diagram of the expression-level deviation in progeny from the two parents. (F) Distribution of expression-level deviations of the FGS and lncRNAs in 105 maize IBM RILs from their two parents. (0,0) means the expression levels of transcripts in 105 RILs are similar to the levels of the two parents.
