Arabidopsis bHLH160 AS patterns and the proposed regulatory function of the splice variant. (a) Gene structure of the transcript isoforms of Arabidopsis bHLH160. (b) Protein 3D structure of the Arabidopsis bHLH160 proteins adapted from Ma et al., 1994 and their regulatory roles. (c) Expression profile of Arabidopsis bHLH160. Error bars indicate the standard deviation. Pies charts under each condition indicate the proportion of each AS isoform present relative to the total expression from the locus. Red lines above the barplot indicate significantly changed gene expression. (d) Gene structure of the transcript isoforms of Camelina sativa LOC104712692, LOC104701783, and LOC104750970. Angled lines indicate introns; black thin boxes indicate UTRs; thick boxes indicate CDS; orange, green, and purple indicate basic, helix, and loop, respectively, in the bHLH domain. (e) Multiple sequence alignments of the protein isoforms from Arabidopsis thaliana bHLH160, Camelina sativa LOC104712692, LOC104701783, and LOC104750970. The bHLH domain is indicated within black boxes
