Dissecting seed pigmentation-associated genomic loci and genes by employing dual approaches of reference-based and k-mer-based GWAS with 438 Glycine accessions

A proposed model for ‘Mirtron-Triggered Gene Silencing (MTGS)’ mechanism working on genome-wide CHS regulatory circuit.
It is noteworthy that the mirtron-derived primary miRNAs involve intron segments originated from CHS1/CHS3-containing transcript whereas the secondary siRNAs are all generated from the exon regions of other CHS transcripts. Abbreviations are as follows: RISC, RNA-induced silencing complex; AGO, argonaute proteins; RDR, RNA dependent RNA polymerase; DCL, dicer-like protein.
