INTRODUCTION
miRNAs were first identified as regulators of the juvenile-to-adult
transition in Caenorhabditis elegans.The founding members of this
class of regulatory RNAs,lin-4 (Lee et al.,1993) and let-7 (Reinhart
et al.,2000),are expressed late in larval development and promote
adult development by repressing the expression of genes required
for the expression of juvenile traits (Ambros,2000; Pasquinelli and
Ruvkun,2002).Recent studies indicate that miRNAs and other
endogenous small RNAs also regulate developmental transitions in
plants.In plants,the shoot apex progresses through juvenile and
adult phases of vegetative development before undergoing a
transition to reproductive development (Baurle and Dean,2006;
Poethig,1990).Several miRNAs have been shown to affect
flowering time when over-expressed in Arabidopsis (Achard et al.,
2004; Chen,2004; Schwab et al.,2005),and the temporal expression
pattern of one of these,miR172,suggests that it may promote both
vegetative phase change and floral induction (Aukerman and Sakai,
2003).miR172 exhibits a similar temporal expression pattern in
maize,where it targets Glossy15(Gl15),a gene required for the
expression of juvenile epidermal traits (Evans et al.,1994; Lauter et
al.,2005; Moose and Sisco,1994).Additional evidence for the
involvement of small RNAs in vegetative phase change is provided
by the observation that mutations in the genes required for the
biogenesis of miRNAs (Clarke et al.,1999; Grigg et al.,2005; Park
et al.,2005; Ray et al.,1996; Telfer and Poethig,1998),or for posttranscriptional
gene silencing (PTGS,also known as RNAi) (Morel
et al.,2002; Peragine et al.,2004),have a precocious vegetative
phenotype.However,there is still no conclusive evidence that
temporal variation in miRNAs or endogenous siRNAs contribute to
vegetative phase change or floral induction.
