AbstractUV-B regulation of anthocyanin biosynthesis in vegetative and grapevine berry tissues has been extensively described. However, its relation with UV-B-regulated microRNAs (miRNAs) has not been addressed before in this species. We explored by deep sequencing of small RNA libraries the developmental dynamics and UV-B effects on miRNAs and associated phased small interfering RNA (phasi-RNAs)-producing loci abundances inin vitro-grown plantlets, in field-grown berry skins of cv. Cabernet Sauvignon, and low- and high UV-B fluence treatments of greenhouse-grown berries at several time points around veraison. We observed by RNA blotting a differential effect of low-versus high-fluence UV-B on miR828 abundances (an effector of anthocyanins and UV-absorbing polyphenolics) across berry development, and identified other miRNAs that correlated with miR828 dynamics. The functional significance of the observed UV-coordinated miRNA responses to UV was supported by degradome evidences of AGO-programmed slicing of mRNAs. Inverse co-expression of the up-regulated miRNAs miR156, miR482, miR530, and miR828 with cognate target gene expressions in response to high fluence UV-B measured by quantitative real-time PCR. These UV-response relationships were also corroborated by analyzing three published transcriptome datasets (berries subjected to UV-C for 1 hr [at pre-veraison], UV-B for five weeks post-veraison, and five red-skinned varieties across four berry development time points). Based on observed significant changes by UV-B on miRNA and derivative phasi-RNA abundances, we propose a regulatory network model of UV responses impacting anti-oxidant and stress-associated polyphenolic compound biosynthesis. In this model high-fluence UV-B increases miR168 (validated in a UV-B small RNA-derived degradome library to targetARGONAUTE1, which spawns phasi-RNAs) and miR530 (targets a novel Plus-3 domain mRNA), while decreasing miR403 abundances (validated to targetARGONAUTE2), thereby coordinating post-transcriptional gene silencing activities by different AGOs. Up-regulation of miR3627/4376 (validated to target Ca2+-transporting ATPase10 that spawns phasi-RNAs) could facilitate anthocyanin accumulation. miR395 and miR399, induced by sulfur and phosphorus starvation in other species (conditions known to trigger anthocyanin accumulation) respond positively to UV-B radiation and are shown to slice cognate targets in grapevine. miR156/miR535 is shown to targetSQUAMOSA PROMOTER-BINDINGtranscription factor genes that potentially regulate the activities of MYB-bHLH-WD40 complexes and thereby anthocyanin biosynthesis. Increases in MYB-bHLH-WD40 TFs could also contribute to the observed up-regulation of miR828 via the conserved and degradome-validated auto-regulatory loop involving miR828/TAS4abcto regulateMYBA6/A7/A5-MYB113-likelevels and thereby anthocyanin levels. These results and meta-analysis provide a basis for systems approaches to better understand non-coding RNA functions in response to UV.

Berry Composition

Late ripening berry dehydration is an important phenomenon that occurs through grape berry water loss due to the alteration of the fruit water budget when transpiration and potential water back flow to the plant exceed the import of water into the berry through the phloem and xylem. Berry shrivelling can have a significant economic impact, reducing yields by ≥25 % with consequences on berry composition and the resulting wine. Its occurrence and consequences are expected to increase due to predicted climate change, shifting grape development and ripening into warmer periods (i.e., heat waves and drought events).
