PHO2 is a ubiquitin-conjugating E2 enzyme for post-translational protein degradation [71] and controls P starvation response genes, such as IPS1, PHT1;8 and PHT1;9. The phloem-mobile shoot to root signal for low shoot P includes miR399, which targets the major PHR1 transcription factor gene.

However, miR399 and miR156 were not among the differentially methylated miRNAs, excluding that these regulons are directly targeted by DNA methylation.

Overexpression of miR399 phenocopies the response to low P [i] in roots [72].

For instance, in many plant species, miRNA targeted genes are involved in a mechanistic network of plant P signaling, e. g. the miR399-PHR1-PHO2 regulon [22, 23], the miR156-SPL3-Pht1;5 pathway [24] and the miR827-NLA-P [i] homeostasis network [25].

This novel link to P-nutrition, of DMR-derived miRNAs that respond to P nutrition, is especially interesting, as plant P signaling involves a mechanistic network of protein coding genes targeted by microRNAs, such as the miR399-PHR1-PHO2 regulon, which was identified in many plant species, including poplar [22].

Franco-Zorrilla et al. (2007) reported that over -expression of the non-coding gene IPS1 inhibited miR399 and increased expression of the target of miR399.

Arabidopsis IPS1 is the first target mimic identified that is complementary to, and regulates the expression of, miR-399.

In Oryza and Populus, we find no new miSquare families, but three new members of known miRBase families (oza-MIR399, ptc-MIR166, and ptc-MIR395; see Table 2).
