Antisense RNA (asRNA) COOLAIR is expressed at A. thaliana FLOWERING LOCUS C (FLC) in response to winter temperatures. Its contribution to cold-induced silencing of FLC was proposed but its functional and evolutionary significance remain unclear. Here we identify a highly conserved block containing the COOLAIR first exon and core promoter at the 3' end of several FLC orthologues. Furthermore, asRNAs related to COOLAIR are expressed at FLC loci in the perennials A. alpina and A. lyrata, although s ...[more]
