For instance, the targets of miR156 and miR160 were genes encoding squamosa promoter -binding (SPB) proteins; the target genes of miR166 encoded a homeodomain-leucine zipper protein (HD-ZIP); and miR159, miR164, and miR319 targeted myeloblastic leukemia (MYB) factors.

The targets of miR156 and miR160 were genes encoding ARF, whereas miR164 and miR166 both targeted NAC domain proteins.

For example, expression of miR156, miR160, miR164, miR166, miR168, miR398, and miR408 increases while miR159 shows reduced expression after UV-B radiation in P. tremula [10].

In P. euphratica, miR156, miR164, and miR408 are differentially expressed under dehydration stress [22], and miR156, miR319, and miR166 respond to drought stress [21].

In total, 15 qPCR validation reactions (designed for detecting the expression of miR156, miR159, miR160, miR164, miR166, miR168, miR172, miR319, miR398, miR408, miR1448, and miR1450) for the 41 fungi-response miRNAs tested were carried out.

Group II contained miR156, miR160, miR164, miR1448, miR398, miR408, and three members of miR166; expression of these miRNAs was always higher at 5 DAI than that at 3 or 7 DAI.

These probes belong to 12 miRNA families (miR156, miR159, miR160, miR164, miR166, miR168, miR172, miR319, miR398, miR408, miR1448, and miR1450) and account for 17.52% of the 234 probes.

Group I included miR159, miR168, miR172, miR319 (miR319f-h), miR1450, and 13 members of miR166.

Pde-MIR171 family had two conserved targets, while pde-MIR162 and pde-MIR166 families each had only one conserved target.

For example, HD-ZIP and GRAS family transcription factors, which are important to root and nodule development in Medicago truncatula and nutrient homeostasis in maize, were predicted to be targets of pde-MIR166 and pde-MIR171, respectively [50, 51].

It includes DCL1 targeted by pde-miR162, GRAS family transcription factor cleaved by pde-miR171, Class III HD-Zip protein HDZ33 regulated by pde-miR166 and CC-NBS-LRR resistance-like protein sliced by pde-miR2118.

It includes pde-MIR159, pde-MIR162, pde-MIR166, pde-MIR169, pde-MIR171, pde-MIR390, pde-MIR396 and pde-MIR399.

The result suggests that pde-miR166 may play key roles in a variety of physiological processes in P. densata needles.

miRNA166, targeting APETALA2 and type III homeodomain-leucine zipper (HD-Zip) family genes, was dramatically up-regulated in female flower, suggesting AP2 and HD-ZiP genes might be negatively regulated in female flower [29].

The expression levels of a few miRNA families, such as miR166 and miR472, were extraordinarily high in both libraries (Table 2).

For example, miR166 members varied in abundance from 695 to 2,157,665 reads.

miR166 was the most abundant, with 2,157,665 (F) and 142, 916 (M) reads accounting for 62.5% and 47.1% of all conserved miRNA reads, respectively.

miR156, miR159, miR166, miR172, miR390, miR396, and miR5021 are the most expressed families in bud tissues.

Most of conserved families common to Arabidopsis and peach (miR156, miR159, miR160, miR164, miR166, miR171, miR172, miR319, miR390, miR395, and miR396) did not show significant size variation (Figure 4).

Prigge and Clark [73], and Floyd and Bowman [75] have previously suggested that HD-Zip III sequences across all land plants produce transcripts that could be targeted by miRNA165 and miRNA166.

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).

In Arabidopsis, only the miR171 family is divided in two families, and the following miRBase families are pairwise grouped together: MIR319–MIR159, MIR156–MIR157, MIR165–MIR166, and MIR170–MIR171.
