In the present study, we selected four distinct cla.ses of light-regula.ed promoters. The light-regula.ed promoters ca. be distinctly grouped into either Ta.a.box-conta.ning or Ta.a.less （initia.or-conta.ning） promoters. Further, using either na.ive promoters or their swa.ped versions of core promoter elements, we esta.lished tha. Ta.a.box a.d Inr （Initia.or） elements ha.e distinct mecha.isms which a.e involved in light-media.ed regula.ion, a.d these elements a.e not swa.pa.le. We identified tha. muta.ions in either functiona. Ta.a.box or Inr elements lea. to the forma.ion of nucleosoma. structure. The nucleotide diversity in either the Ta.a.box or Inr element in a.a.idopsis ecotypes proposes tha. the nucleotide va.ia.ion in core promoters ca. a.ter the gene expression. We show tha. motif overrepresenta.ion in light-a.tiva.ed promoters encompa.ses different specific regula.ory motifs present downstrea. of TSS （tra.scription sta.t site）, a.d this might serve a. a.k.y fa.tor in regula.ing light promoters which a.e pa.a.lel with these elements. Fina.ly, we conclude tha. the Ta.a.box or Inr element does not a.t in isola.ion, but our results clea.ly suggests the proba.le involvement of other distinct core promoter elements in concurrence with the Ta.a.box or Inr element to impa.t selectivity to light-media.ed tra.scription.
