A large fraction of the genes in Arabidopsis have antisense
transcripts (Borsani et al., 2005; Jen et al., 2005; Wang et al., 2005a;
Yamada et al., 2003). In most cases, these transcript pairs represent
neighboring, divergently transcribed protein-coding genes that
overlap for a region of their 3\2 ends. By contrast, the SPL3 antisense
transcript is nearly the same size as the sense transcript, it completely
encompasses the sense transcript and it does have significant coding
potential, suggesting that this transcript is dependent on sequencesthat are important for the expression of the sense transcript. Whether
this transcript plays a role in the expression of the sense transcript
remains to be determined.
The results of this and other (Schmid et al., 2003; Schwab et al.,
2005) studies indicate that SPL3 and the related genes, SPL4 and
SPL5, are under complex transcriptional and post-transcriptional
regulation. We are particularly intrigued by these three genes
because they establish a link between miRNAs and vegetative phase
change in Arabidopsis, and reveal that temporal variation in miRNA
expression plays a regulatory role in developmental timing in plants.
Further studies will be necessary to determine the precise
mechanism by which SPL3/4/5 expression is controlled during
vegetative and reproductive phase change, and the regulatory
pathways in which these genes operate.
We thank Manabu Yoshikawa for preliminary experiments that contributed to
the work described here, and to Stewart Gillmor for helpful comments on this
manuscript. ABRC and the FST project provided the T-DNA insertion lines used
in this study. This research was supported by a grant from the NIH to R.S.P.
