　　miR394a/b are conserved small RNAs but whether miR394a/b and its target gene LCR (LEAF CURLING RESPONSIVENESS) are involved in regulation of plant response to abscisic acid (ABA) and abiotic stresses is unknown.Here we show that miR394a/b are induced by ABA, whereas its target LCR expression is depressed by ABA.Analysis of LCR and its promoter (pLCR: : GUS) revealed that LCR is expressed at all development stages.
