“…Ethylene is extensively involved in plant growth and development, and plays an essential regulatory role in fruit ripening, softening and cracking ( Bapat et al., 2010 ; Chen et al., 2019 ). ERFs are located downstream of the ethylene signaling pathway, previous studies have shown that ERF4 was associated with fruit ripening and cracking in watermelon and tomato ( Liao et al., 2019 ; Hu et al., 2022 ).…”

Fruit cracking tremendously damages the appearance of fruit, easily leads to pathogen invasion, greatly reduces the marketability and causes immense economic losses. The pivotal role of long non-coding RNAs (lncRNAs) in diverse biological processes has been confirmed, while the roles of lncRNAs underlying fruit cracking remain poorly understood. In this study, the incidence of fruit cracking was 7.26% under the bagging treatment, the control group was 38.11%, indicating that bagging considerably diminished the fruit cracking rate. LncRNA libraries for fruit cracking (FC), fruit non-cracking (FNC) and fruit non-cracking under bagging (FB) in pomegranate (Punica granatum L.) were performed and analysed via high-throughput transcriptome sequencing. A total of 3194 lncRNAs were obtained with a total length of 4898846 nt and an average length of 1533.77 nt in pomegranate. We identified 42 differentially expressed lncRNAs (DELs) and 137 differentially expressed mRNAs (DEGs) in FC vs FNC and 35 DELs and 160 DEGs in FB vs FC that formed co-expression networks respectively, suggesting that there are involved in phytohormone signaling pathway, lignin catabolic process, lipid transport/binding, cutin biosynthetic process and cell wall organization. We also found that 18 cis-acting DELs regulated 18 target genes, and 10 trans-acting DELs regulated 24 target genes in FC vs FNC, 23 DELs regulate 23 target genes for the cis-acting lncRNAs and 12 DELs regulated 36 target genes in FB vs FC, which provides an understanding for the regulation of the fruit cracking. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis results demonstrated that DELs participated in calcium ion binding, glycerophospholipid metabolism, flavonoid biosynthetic process, cell wall biogenesis, xyloglucan metabolic process, hormone signal transduction and starch and sucrose metabolism. Our findings provide new insights into the roles of lncRNAs in regulating the fruit cracking and lay the foundation for further improvement of pomegranate quality.

“…Previous study in peach fruit reported that PpERF4 enhances the transcription of PpACO1 by binding to its promoter in ( Wang et al, 2021 ). ERF4 also represses the expression of ACS1 and ACO1 by interacting with JAZ in apple fruit ( Hu et al, 2022 ). Similar results were reported in blueberry ( Zhou et al, 2021 ).…”

Ethylene burst is an important sign of the initiation of postharvest mango ripening and softening is a typical characteristic of fruit ripening. However, the intrinsic link between ethylene release and fruit softening during ripening of postharvest mangoes is still not clear. The aim of this study was to investigate the effects of ethylene and its action inhibitor 1-methylcyclopropene (1-MCP) on fruit softening and ripening and the underlying regulatory mechanisms. Results showed that ethephon (ETH) promoted ethylene release and enhanced MDA content and activities of cell wall degrading enzymes, whereas 1-MCP treatment exhibited an opposite effect. Moreover, real-time quantitative polymerase chain reaction indicated that the transcription levels of genes involved in cell wall degradation (MiPG, Miβ-GAL and MiPE), ethylene biosynthesis (MiACO1 and MiACS6) and ethylene response factor (MiERF8) were remarkably induced by ETH. Correlation analysis further revealed that the production of ethylene was significantly negatively correlated with firmness, but positively correlated with MDA content, activities of cell wall degrading enzymes and expressions of MiPG and Miβ-GAL. Furthermore, yeast one hybrid (Y1H) assay showed that MiERF2 and MiERF8 could directly bind to the promotor of MiPG and then regulate its transcription. These findings suggest that ethylene production is closely associated with fruit softening, and MiERF2 and MiERF8 and MiPG may play crucial roles in regulation of ripening and softening of postharvest mangoes.

“…For example, JA-ET signalling responds to fungal infections against the symptom of excessive preharvest fruit drop in citrus (Zhao et al, 2020). Meanwhile, the application of JA activates the transcription factor MdMYC2 to interact with Ethylene response factor 4 (MdERF4 ), thereby inhibiting the expression of ripening-specific genes ACC synthase 1 (MdACS1 ) and ACC oxidase 1 (MdACO1 ), delaying ripening in apple (Malus Domestica ) (Hu et al , 2022). Furthermore, application of MeJA and its synthetic like analoguesn -propyl dihydrojasmonate and prohydrojasmon can lead to obvious ripening delay in peach by up-regulating the expression ofEthylene response sensor 1 (PpERS1 ), phenylalanine ammonia lyase (PAL ), chalcone synthase (CHS ) andflavanone-3-hydroxylase (F3H ), thereby reducing ethylene emission and accumulating anthocyanins, simultaneously yielding softening and colour development (Soto et al , 2012;Wanget al , 2021;Tang et al , 2022).…”

Jasmonic acid (JA) is an important phytohormone in optimizing plant developmental growth and stress responses. The biosynthesis and signalling pathways of JA share common and unique features between herbaceous and woody plants. However, numerous reports have primarily focused on JA function in model plant species or herbaceous plants, leading to a notable lack of research on the JA regulatory mechanism in woody plants. In particular, the role of Jas in posttranscriptional regulation events such as alternative splicing (AS), has largely not been elucidated in trees. In this review article, we summarize the current progress of JA-involved regulation of developmental growth in different tree species. Along with an accumulating number of studies revealing that AS participates in the JA regulatory network in woody plants, we also update the multiple roles served by JA associated with similar properties and differential regulation within their herbaceous counterparts. The utilization of genetic studies and high-throughput proteogenomic approaches to analyse AS genes and splicing factors involved in JA signalling would further advance our understanding of JA modulation in woody plants.
