“…Similar results were reported in studies on Actinidia eriantha [45], Pyrus pyrifolia [62], Malus domestica [63], Eriobotrya japonica [64], and other fruit tree species. In addition, NAC TFs also regulate fruit development and ripening through multiple hormone such as ethylene and abscisic acid biosynthesis and signal transduction pathways [65]. For instances, in tomato, SNAC4 and SNAC9 could positively regulate the fruit ripening process by interacting with ethylene synthesis genes [66].…”

The NAC (NAM, ATAF and CUC) gene family plays a crucial role in the transcriptional regulation of various biological processes and has been identified and characterized in multiple plant species. However, genome-wide identification of this gene family has not been implemented in Juglans mandshurica, and specific functions of these genes in the development of fruits remain unknown. In this study, we performed genome-wide identification and functional analysis of the NAC gene family during fruit development and identified a total of 114 JmNAC genes in the J. mandshurica genome. Chromosomal location analysis revealed that JmNAC genes were unevenly distributed in 16 chromosomes; the highest numbers were found in chromosomes 2 and 4. Furthermore, according to the homologues of JmNAC genes in Arabidopsis thaliana, a phylogenetic tree was constructed, and the results demonstrated 114 JmNAC genes, which were divided into eight subgroups. Four JmNAC gene pairs were identified as the result of tandem duplicates. Tissue-specific analysis of JmNAC genes during different developmental stages revealed that 39 and 25 JmNAC genes exhibited upregulation during the mature stage in walnut exocarp and embryos, indicating that they may serve key functions in fruit development. Furthermore, 12 upregulated JmNAC genes were common in fruit ripening stage in walnut exocarp and embryos, which demonstrated that these genes were positively correlated with fruit development in J. mandshurica. This study provides new insights into the regulatory functions of JmNAC genes during fruit development in J. mandshurica, thereby improving the understanding of characteristics and evolution of the JmNAC gene family.

“…Overexpression of Sl-SAUR69 in tomato causes premature initiation of ripening, whereas its downregulation delays ripening initiation [139,142]. There are many reports of the effects of ABA on ripening, as discussed by Zhu et al [157] and reviewed recently by Kou et al [158][159][160]. ABA is synthesised from carotenoids via the action of 9-cis-epoxycarotenoid dehydrogenase (NCED) [161,162].…”

This article focuses on the molecular and hormonal mechanisms underlying the control of fleshy fruit ripening and quality. Recent research on tomato shows that ethylene, acting through transcription factors, is responsible for the initiation of tomato ripening. Several other hormones, including abscisic acid (ABA), jasmonic acid (JA) and brassinosteroids (BR), promote ripening by upregulating ethylene biosynthesis genes in different fruits. Changes to histone marks and DNA methylation are associated with the activation of ripening genes and are necessary for ripening initiation. Light, detected by different photoreceptors and operating through ELONGATED HYPOCOTYL 5(HY5), also modulates ripening. Re-evaluation of the roles of ‘master regulators’ indicates that MADS-RIN, NAC-NOR, Nor-like1 and other MADS and NAC genes, together with ethylene, promote the full expression of genes required for further ethylene synthesis and change in colour, flavour, texture and progression of ripening. Several different types of non-coding RNAs are involved in regulating expression of ripening genes, but further clarification of their diverse mechanisms of action is required. We discuss a model that integrates the main hormonal and genetic regulatory interactions governing the ripening of tomato fruit and consider variations in ripening regulatory circuits that operate in other fruits.

“…Most NAC TFs exhibit binding activities to NAC recognition sequence (NACRS) cis -element with the sequence of CATGT or CACG ( Tran et al, 2004 ), which are frequently present in promoters of certain defense genes. Functional studies using knockout/knockdown mutants and/or overexpression transgenic lines have demonstrated that NAC TFs play significant roles in plant growth, development, and response to biotic and abiotic stress ( Puranik et al, 2012 ; Shao et al, 2015 ; Kim et al, 2016 ; Yuan et al, 2019a ; Diao et al, 2020 ; Forlani et al, 2021 ; Kou et al, 2021 ).…”

NAC transcriptional factors constitute a large family in rice and some of them have been demonstrated to play crucial roles in rice immunity. The present study investigated the function and mechanism of ONAC066 in rice immunity. ONAC066 shows transcription activator activity that depends on its C-terminal region in rice cells. ONAC066-OE plants exhibited enhanced resistance while ONAC066-Ri and onac066-1 plants showed attenuated resistance to Magnaporthe oryzae. A total of 81 genes were found to be up-regulated in ONAC066-OE plants, and 26 of them were predicted to be induced by M. oryzae. Four OsWRKY genes, including OsWRKY45 and OsWRKY62, were up-regulated in ONAC066-OE plants but down-regulated in ONAC066-Ri plants. ONAC066 bound to NAC core-binding site in OsWRKY62 promoter and activated OsWRKY62 expression, indicating that OsWRKY62 is a ONAC066 target. A set of cytochrome P450 genes were found to be co-expressed with ONAC066 and 5 of them were up-regulated in ONAC066-OE plants but down-regulated in ONAC066-Ri plants. ONAC066 bound to promoters of cytochrome P450 genes LOC_Os02g30110, LOC_Os06g37300, and LOC_Os02g36150 and activated their transcription, indicating that these three cytochrome P450 genes are ONAC066 targets. These results suggest that ONAC066, as a transcription activator, positively contributes to rice immunity through modulating the expression of OsWRKY62 and a set of cytochrome P450 genes to activate defense response.
