Auxin -regulating miRNAs are clearly modulated in our data: miR390, targeting ARF via ta-siRNA production, and miR393, targeting auxin receptors are both up-regulated (Fig.   8B) at late inflorescence development (Flower_FB and Flower_F), with open flowers, thus suggesting a role for this hormone in the first stages of inflorescence development. [score:11]
miR390 regulates the Auxin Response Factor (ARF) through Trans-Acting siRNA locus 3 (TAS3), as experimentally validated in [28], while miR393 targets the auxin receptor TIR and an F-box protein [28] highlighting the importance of auxin regulation during flower development. [score:6]
Other two interesting miRNAs are vvi-miR390 and vvi-miR393, both involved in auxin signalling regulation, are up-regulated during inflorescence and flower development (Figs.   8B and 9C). [score:6]
A previous work in the hybrid Summer Black (V. vinifera x V. labrusca) showed a down-regulation of miR390 and miR393 in open flowers, compared to young inflorescences [27]. [score:3]

TAS3 is a target of miR390 and its ta-siRNA can target the auxin response factor gene family [8]. [score:5]
Previously we reported that the TAS3 from Vitis vinifera (vvi TAS3) can be targeted by vvi-miR390 to trigger ta-siRNA production in grapevine [12]. [score:3]
Therefore, we looked for ca-siRNA targeting sites on vvi TAS3 and the flanking 300 bp upstream and downstream of the gene where the two miR390 binding sites were located. [score:3]
We used the same method and criteria to examine the antisense strand that was not targeted by miR390. [score:3]
Overview of Small RNA Distribution on TAS3 from Vitis viniferaPreviously we reported that the TAS3 from Vitis vinifera (vvi TAS3) can be targeted by vvi-miR390 to trigger ta-siRNA production in grapevine [12]. [score:3]
Only 14 (18%) of the positions were found to belong to phased positions set by vvi-miR390 when a 1-nt offset from the phased positions was allowed. [score:1]
TAS3 is flanked by two miR390 binding sites; one of which can be cleaved by the interaction of miR390 and AGO7, and another that is non-cleavable. [score:1]
This finding suggested that cis-cleavage might use a different mechanism from the mechanism used by miR390 to initiate the cleavage of vvi TAS3. [score:1]
It has been demonstrated that two miR390 binding sites located on each side of TAS3 are critical for TAS3 ta-siRNAs biogenesis [8]. [score:1]
When the number of sRNAs located in the phased positions set by ca-siRNAs was counted, we found that 54 unique sRNA located in non-phased positions set by miRNA390 were included in the phasing patterns. [score:1]
Because the cleavage of phasing sRNAs often occurs within 1–2 nt of the phased position [8, 13], we propose that the production of ca-siRM147, ca-siRM72, and ca-siRM94 is triggered by miR390, ca-siRM147, and ca-siRM147, respectively. [score:1]
It has been shown that ca-siRM147 can be triggered by miR390 [12], but for other ca-siRNAs the triggers remain unclear because they are out of the register set by miR390. [score:1]

Indeed, in WW conditions, most conserved miRNAs that were validated by qRT-PCR (miR164, miR168, miR172, miR319, miR390, miR394, miR2111, miR3624, miR3629, miR3639) were expressed at higher levels in infected plants than in GRSPaV-free plants (Fig. 2, Supplementary Fig. S4). [score:3]
Notably, most differences in miRNA accumulation between infected and GRSPaV-free plants disappeared in SWS conditions and significant differences in expression remained only for miR166, miR319, miR390, and miR3639 (Supplementary Fig. S4). [score:3]

Among them, miR160, miR167, miR390 and miR393 contribute to PTI by regulating the expression of genes encoding different auxin response factors (ARFs) and auxin receptors involved in auxin signalling, thereby promoting inhibition of pathogen growth [90]. [score:6]
