For example, the target genes of miR156 and miR1448 encoded plant disease resistance proteins (NBS-LRR proteins); two targets of miR164 encoded LRR defense proteins and TMV-resistance proteins; one target of miR398 and miR159 encoded two pathogenesis-related proteins, CSD and peroxidase (POD), respectively; and one target of miR159 encoded cytokinin oxidase (CKX) family proteins.

The promoters of these three miRNAs are highly abundant in the MBS box, implicating MYB in their activation/repression; thus, evidence that miR159, miR164, and miR319 are positively regulated by the transcription factors they target suggests that the expression of these targets is modulated by a negative feedback loop that buffers small changes in the level of their mRNAs.

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.

Although experimental evidence for MYB involvement in plant disease stress is scarce, the ubiquitous distribution of MBS motifs in this study and the three fungal response miRNA (miR159, miR164, and miR319) targeting MYB TFs illustrate that MBS motifs are also tightly associated with plant disease response.

Poplar canker pathogen, B. dothidea, induced expression of miR159, miR164, and miR319, and these three miRNAs targeted MYB factors (Table S3), suggesting the miRNA -mediated regulation of MYB factors.

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].

But why the expression level of poplar miR1448 and miR164 which also targeted NBS-LRR protein genes increased response to canker pathogen?

Therefore, miR164 might also play an important role in disease responsiveness in plants, especially in Populus; however, the resistance mechanism of miR164 (through auxin signal transduction, disease resistance proteins, or both pathways together) remains unclear.

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

We also noticed that poplar miR164 targeted some disease resistance proteins in this study.

Auxin signal transduction is related to bacterial disease resistance in Arabidopsis [14], and this study indicated that miR160, miR167, and miR164 are tightly related to plant disease resistance.

Plants always regulate disease defense through phytohormone signal transduction [54], and several miRNAs (miR159, miR160, miR164, and miR167) were induced by phytohormones [55], [56].

By induction of an auxin signal, miR164 regulates molecular circuitry that controls the separation of developing organs [41] and normal flower development [42].

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.

MiR156, miR159, miR160, miR164, miR168, miR172, and miR408 are significantly expressed in tension- and compression-stressed developing xylem of P. trichocarpa [12], and miR156, miR160, miR164, and miR168 also respond to cold stress in P. trichocarpa [4].

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.

Moreover, an auxin signal transduction feedback regulatory network of miR167-ARF in rice [58], [59] and miR164-NAC in Arabidopsis [60] have also been described.

In these diverse examples, miR156 and miR164, two miRNAs that respond to many environmental stresses, are both involved in the miRNA-TF feedback regulatory network, suggesting their key roles in stress responses.

Similar to miR156, miR164 also responds to different stresses in diverse plants [4], [5], [10], [12], [22], [35], [36], [37].

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.

The ten most highly expressed miRNAs (miR156, miR157, miR159, miR164, miR167, miR172, miR393, miR396, miR414, miR2275, and miR5021) in buds and leaves are miRNAs regulating genes involved in flower and leaf development processes such as integument development, leaf morphogenesis, meristem initiation, maintenance, and growth, bilateral symmetry determination, organ morphogenesis, plant phase transition, shoot apical meristem identity, flower and fruit development, and plant architecture.

Members of four families (miR5021, miR164, miR414, miR396, miR2919) target genes encoding proteins involved in dormancy such as embryo-defective or maternal effect embryo arrest 14 (MEE14).

In silico expression analyses of miRNAs using DEGseq [25] identified 19 sequences belonging to eight conserved miRNA families (miR156, miR157, miR164, miR172, miR393, miR396, miR414, and miR2275) induced in winter buds versus leaves (Additional file 6: Table S6).

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).

The present study revealed that miRNA164 was not expressed in female or male flower, indicating miRNA164 might show stage-specific expression in flower development.

For example, in Arabidopsis, the miR164 family targets a subset of NAC transcription factors including CUP-SHAPED COTYLEDON1 (CUC1) and CUC2, which mediate organ boundary formation.

miRNA159 and miRNA319 also have been reported to act with miRNA164 and miRNA167 in specifying particular cell types during the later stages of flower development [28].

The two downregulated miRNAs (miR160 and miR164) were both identified to be cold-responsive miRNAs in P. trichocarpa [25].

MiR164 has been predicted targete six NAC-domain proteins (PNAC041, PNAC042, PNAC151, PNAC152, PNAC154, and PNAC155) from subfamily NAC-a [57], and NAC-domain proteins have been confirmed to be important in drought stress tolerance [58, 59].

TMV-Cg virus infection in Arabidopsis causes the accumulation of miR160 and miR164 [54].

MiR159 and miR164 have not yet found to be drought-responsive in Populus plants, except in this research.

It is interesting to note that while certain NAC genes are known targets of the miR164 family [6], neither NAC050 nor NAC083 are targets of this deeply conserved miRNA family.

miRNA164, 162a and 168 showed secondary development zone dominant expression.

For example, it has been shown that Arabidopsis Class II TCP AtTCP4 regulates the serration at the leaf margin by influencing auxin distribution via the miR164-CUC pathway 63.

For example, transcripts of the NAC1 gene (At1g56010), which is a target of microRNA ath-Mir164 [33], have both cis- and trans-NATs.
