Product Information

The sequencing reads from the input samples in m 6A-seq were used for RNA-seq analysis as previously reported [ 21]. In brief, the uniquely mapped reads with a MAPQ ≥ 13 were assembled by Cufflinks [ 81]. Gene expression was presented as fragments per kilobase of exon per million mapped fragments (FPKM) by using Cuffdiff [ 81], which concurrently provides statistical routines for capturing differentially expressed genes. The Benjamini and Hochberg’s approach [ 82] was used to adjust the resulting P values for controlling the false discovery rate (FDR). Differential gene expression was defined on basis of a cutoff criterion of FPKM fold change ≥ 1.5 and P value < 0.05. Quantitative RT-PCR analysis Most plants have a root system that consists of a primary root or primary roots with root branches forming and growing from the primary root. Strawberry plants have this arrangement for the majority of their root system. However, they also have a special advantage: adventitious root formation at the nodes of their stolons. The diploid woodland strawberry ( Fragaria vesca cv. “Hawaii-4”) and the octoploid cultivated strawberry ( Fragaria × ananassa cv. “Benihoppe”) were planted in a greenhouse with standard culture conditions [ 59]. To accurately determine fruit ages through development, flowers were tagged at the anthesis. Fruits of “Hawaii-4” at the growth stage 6 (S6), the ripening stage 1 (RS1), and the ripening stage 3 (RS3) [ 38], which were on average 15, 21, and 27 days post-anthesis (DPA), respectively, were harvested, and then frozen in liquid nitrogen. The fruits with the removal of attached achenes were subsequently stored at − 80 °C until use. The ‘Benihoppe’ fruits were harvested at the small green (SG), large green (LG), white (Wt), initial red (IR), and full red (FR) stages, respectively, based on the size, weight, shape, and color [ 72], and then maintained at fresh status for further studies or directly frozen and stored as the “Hawaii-4.” m 6A-seq and data analysis

In all the cultivars, the shoot growth was induced from the meristem cultured on both the medium without Kn (control) and that with low concentration of Kn (0.5 mg L −1), although the induction was stronger in the latter. Surprisingly, no shoot induction was observed in the media containing more than 0.5 mg L −1 (data not shown), which may be due to Kn toxicity to plant cells and tissues. After transferring the explants to the rooting and plant growth medium, the number of shoots that developed per explant was significantly higher in plants cultured on the medium containing Kn 0.5 mg L −1 than in the control. In addition, the shoots induced by 0.5 mg L −1 Kn were likely to be healthier and produced more leaves and roots than those derived from explants grown in the Kn-free medium. This improved growth performance may be explained by the promoting effect of Kn on cell division, leading to higher number of shoots, leaves, and roots. A greater number of surviving shoots and superior plant growth were also observed in explants derived from cultures on the medium with 0.5 mg L −1 Kn during acclimation, which may be attributed to their primarily healthier shoots as compared to those derived from the control. Furthermore, these Kn-derived plants thrived in the greenhouse conditions and were genetically stable in comparison with conventionally propagated plants, as indicated by flow cytometry and RAPD markers. Once the fruits of all cultivars were harvested, fruits of uniform size were selected from each cultivar and each individual fruit was cut in half. Both halves of each fruit were analyzed for flesh firmness and total sugar content. Flesh firmness was determined using a Rheo-meter (Compac-100II; Sun Scientific Co., Tokyo, Japan), and total sugar content was measured using a Digital Refractometer GMK-703AC (G-won hightech, Korea), as described by Lee et al. [ 24]. The firmness and sugar content measurements were taken from the stem end of fruits, where the fruits were broadest. Each measurement was conducted using 10 different individual fruits of each cultivar of conventionally propagated and tissue culture-derived plants in each of the three growing seasons. This experiment was repeated three times (10 fruits × 5 cultivars × 2 plant types × 3 growing seasons × 3 replications of the experiment = 900 total fruit evaluated per measurement type). Statistical analysis The ABA biosynthesis rate-limiting enzyme NCED was reported to play an essential role in the ripening of strawberry fruit [ 34, 38]. Moreover, several critical constituents of ABA signaling, including the ABA receptor FaPYR1 and FaABAR, the type 2C protein phosphatase FaABI1, and the SNF1-related kinase FaSnRK2.6, have been revealed to be indispensable for normal fruit ripening of strawberry [ 57, 58, 59]. Nevertheless, the regulatory mechanisms underlying ABA biosynthesis and signaling pathway remain largely unknown. Debnath SC.

Due to the critical role of ABA in the regulation of fruit ripening of strawberry, we evaluated whether MTA affects translation efficiency of other genes in the ABA signaling pathway. We found that genes, such as WRKY DNA-binding protein 40 ( WRKY40), exhibited significant changes in translation efficiency when the MTA was silenced or overexpressed (Additional file 1: Figure S13). This could not be reasonably explained by m 6A deposition because the transcripts of these genes are not m 6A-modified according to our m 6A-seq datasets. We speculate that MTA may regulate translation efficiency of numerous transcripts beyond direct m 6A installation. As expected, MTA repression or overexpression also altered the translation efficiency of a number of ripening-related genes without m 6A modification, such as PG1 relevant to firmness and dihydroflavonol 4-reductase ( DFR) associated with anthocyanin biosynthesis (Additional file 1: Figure S13). The transcript levels of MTA and MTB increased significantly upon ripening initiation of strawberry fruit (Fig. 5c–e), which may account for the m 6A hypermethylation in the CDS region. It should be noted that the m 6A methyltransferase genes in tomato express stably and no obviously global m 6A hypermethylation was observed during fruit ripening [ 36]. By contrast, it is the m 6A demethylase SlALKBH2 that positively regulates tomato fruit ripening through mediating the mRNA stability of SlDML2, a key DNA demethylase gene determining the DNA methylation patterns during ripening [ 36]. Due to the pivotal role of DNA methylation in the regulation of fruit ripening in both climacteric and non-climacteric fruits, it is reasonable to assume that m 6A modification may modulate strawberry fruit ripening by modulating the DNA methylation machinery.

For all the cultivars, shoot induction was successful only in the meristems cultured in the medium without Kn and the medium containing 0.5 mg L −1 Kn. The shoots obtained from explants cultured in media supplemented with 0.5 mg L −1 Kn exhibited better plant growth parameters than those cultured in media without Kn and were genetically stable when compared with conventionally propagated plants for all the cultivars. Vegetative and sexual characters and fruit quality attributes observed in the plants derived from meristems cultured on 0.5 mg L −1 Kn and the conventionally propagated plants were not significantly different when grown for three continuous growing seasons under greenhouse conditions. Conclusion Strawberry undergoes an overall loss of DNA methylation during ripening [ 55]. There are four SlDML2 homologs, FveDME1, FveROS1.1, FveROS1.2, and FveROS1.3, in the strawberry genome (Additional file 1: Figure S15a). Our m 6A-seq analysis revealed that FveDME1 and FveROS1.1 contain differential m 6A peaks upon ripening initiation (from S6 to RS1), while FveROS1.2 and FveROS1.3 are not m 6A-modified (Additional file 1: Figure S15b). However, none of these genes showed significantly increased expression from S6 to RS1 (Additional file 1: Figure S15c), suggesting that the homologs of SlDML2 might be dispensable for m 6A-mediated regulation of ripening in strawberry fruit. Previous study has shown that the reprogramming of DNA methylation during the ripening of strawberry fruit is governed by components in the RNA-directed DNA methylation (RdDM) pathway rather than those in the demethylation pathway [ 55]. Our m 6A-seq data indicated that there was no differential m 6A modification in the transcripts of DNA methyltransferase genes in the RdDM pathway during strawberry fruit ripening (Additional file 1: Figure S16). Together, these data suggest that distinct mechanisms underlie the m 6A-mediated ripening regulation in strawberry fruit. m 6A methylation regulates strawberry fruit ripening by targeting ABA pathway is 42% of the free sugars children aged four to six should eat in a day, or 25% of the free sugar maximum intake for children aged seven to 10. Notably, hundreds of ripening-induced and ripening-repressed genes, which display significantly higher or lower expression in RS1 compared to S6 (Additional file 12: Table S11), exhibit differential m 6A modification (Additional file 14: Table S13; Additional file 15: Table S14). GO analysis revealed that these genes were enriched in processes such as multicellular organismal development, developmental process, nucleocytoplasmic transport, and anatomical structure development (Additional file 1: Figure S7d), implicating the involvement of m 6A methylation in the regulation of strawberry fruit ripening.

In mammals, m 6A methylation has been unveiled to play critical roles in regulating various physiological and pathological processes, such as embryonic and post-embryonic development, cell circadian rhythms, and cancer stem cell proliferation [ 5, 6, 7, 8, 9, 10]. The m 6A marks in mammals are dominantly installed by the methyltransferase complex composed of the stable catalytic core that is formed by methyltransferase-like 3 (METTL3) and METTL14 [ 11, 12, 13], the Wilms tumor 1-associating protein (WTAP) [ 14], and other concomitant functional elements [ 15, 16, 17]. The removal of m 6A marks is executed by two m 6A demethylases, fat mass and obesity-associated protein (FTO) and alkylated DNA repair protein AlkB homolog 5 (ALKBH5) [ 18, 19]. The m 6A modification is recognized by the reader proteins, such as YTH-domain family proteins and specific RNA binding proteins (RBPs), which mediate the downstream effects of m 6A methylation [ 4]. In plants, the m 6A methylation machineries have been characterized in the model plant Arabidopsis thaliana to modulate development processes such as shoot stem cell proliferation, trichome branching, and floral transition [ 20, 21, 22, 23]. Moreover, m 6A has been demonstrated to play pivotal roles in mediating sporogenesis in rice [ 24] and regulating stress responses in maize [ 25]. By contrast, the m 6A methylation machineries as well as the characteristics and functions of m 6A in regulating physiological processes of horticultural crops remain largely unknown. To explore the possibility that MTA and MTB in strawberry function in the form of heterodimer as METTL3 and METTL14 in mammals [ 12, 13], we subsequently analyzed the interactions between MTA and MTB using the yeast two-hybrid (Y2H) system. As shown in Fig. 5f, the yeast cells co-expressing AD-MTA and BD-MTB, but not the negative controls, displayed normal growth on the selective SD/-Leu-Trp-His (-LWH) and SD/-Leu-Trp-His-Ade (-LWHA) solid medium and turn to blue with the addition of X-α-gal, indicating that MTA interacts with MTB. The interactions between MTA and MTB were further verified by the split luciferase complementation imaging (LCI) assay, in which the luciferase activity was detected when MTA-nLUC and cLUC-MTB were co-expressed in N. benthamiana leaves (Fig. 5g). It should be noted that, compared with the MT-A70 domain of MTB, the full-length MTB protein exhibit relatively weaker combining capacity with MTA (Fig. 5g). Subcellular localization analysis by transiently expressing MTA-mCherry and MTB-eGFP fusion proteins in N. benthamiana leaves showed that MTA is present in both the nucleus and cytoplasm, while the MTB protein is specifically localized in the nucleus (Fig. 5h). Interestingly, when MTA-mCherry was co-expressed with MTB-eGFP, the two proteins tend to colocalize in the nucleus (Fig. 5i). m 6A methyltransferases positively regulate strawberry fruit ripening Fruit Shoot ranges three different kinds of fruit drinks with various delicious flavours.
