“…In the last few years, a significant progress has been made in identification of plant CREs with studies of the model plant species Arabidopsis as well as rice, maize, and cotton ( Zhang et al, 2012 ; Pajoro et al, 2014 ; Zhu et al, 2015 ; Rodgers-Melnick et al, 2016 ; Oka et al, 2017 ; Wang et al, 2017 ; Bajic et al, 2018 ; Tannenbaum et al, 2018 ; Zhao et al, 2018a ; Yan et al, 2019 ). The rapid developments are due to adoption of DNase-Seq and ATAC-Seq techniques in plant research, which measure DNA “openness” as a proxy for the accessibility of DNA to transcription factors, RNA polymerase, and other protein complexes involved in gene expression ( Pajoro et al, 2014 ; Wang et al, 2016 ). Improved understanding of the function of the non-coding elements of the genome will provide a new, yet untapped pool of breeding targets.…”
