Abstract

In vitro cultured embryogenic callus was employed as a model to investigate
microRNAs (miRNAs) associated with embryogenesis and post-embryonic development.
Thirty-one miRNAs including 16 novel species were identified from a large number
of small RNAs which were cloned from both differentiated and undifferentiated
rice embryogenic calli. Four target genes of the miRNAs were further validated.
A set of the miRNAs, including miR397 and miR156, exhibited intriguing
expression patterns during the transition from undifferentiated to
differentiated calli. By exploiting the correlations between the differential
expression patterns of these miRNAs and their targets, the regulatory roles of
the miRNAs on meristem maintenance and embryogenesis were indicated.
