“…MADS-box and NAC genes are important regulators of ripening in climacteric fruits [ 12 , 87 ] and also play a role in non-climacteric fruits such as strawberry [ 65 , 88 ]. They generally participate in regulating fruit ripening through influencing other ripening genes [ 12 ] and phytohormone biosynthesis, especially ethylene and ABA [ 89 – 91 ]. FaSHP [ 63 ], FaMADS1a [ 64 ], and FaMADS9 [ 88 , 92 ], an ortholog of tomato Ripening Inhibitor ( RIN ), have been found to participate in strawberry fruit ripening.…”

Abscisic acid (ABA) is a dominant regulator of ripening and quality in non-climacteric fruits. Strawberry is regarded as a model non-climacteric fruit due to its extensive genetic studies and proven suitability for transgenic approaches to understand gene function. Strawberry research has contributed to studies on color, flavor development and fruit softening, and in recent years ABA has been established as a core regulator of strawberry fruit ripening, whereas ethylene plays this role in climacteric fruits. Despite this major difference, several components of the interacting genetic regulatory network in strawberry, such as MADS-box and NAC transcription factors, are similar to those that operate in climacteric fruit. In this review, we summarize recent advances in understanding the role of ABA biosynthesis and signaling and the regulatory network of transcription factors and other phytohormones in strawberry fruit ripening. In addition to providing an update on its ripening, we discuss how strawberry research has helped generate a broader and more comprehensive understandings of the mechanism of non-climacteric fruit ripening and focus attention on the use of strawberry as a model platform for ripening studies.

“…CpNAC3 could interact with CpMADS4, and the interacting proteins had a stronger transcriptional activation effect on CpERF9 and CpEIL5. These results suggest that CpNAC3 and CpMADS1 can independently or synergistically activate the ethylene signal transduction pathways and positively regulate fruit ripening in papaya [74].…”

The NAC transcription factor (TF) family is one of the largest plant-specific TF families and its members are involved in the regulation of many vital biological processes during plant growth and development. Recent studies have found that NAC TFs play important roles during the ripening of fleshy fruits and the development of quality attributes. This review focuses on the advances in our understanding of the function of NAC TFs in different fruits and their involvement in the biosynthesis and signal transduction of plant hormones, fruit textural changes, color transformation, accumulation of flavor compounds, seed development and fruit senescence. We discuss the theoretical basis and potential regulatory models for NAC TFs action and provide a comprehensive view of their multiple roles in modulating different aspects of fruit ripening and quality.

“…Analysis revealed the regulatory control of transcription factors from MADS-box, NAC, GRF and AP2/ERF gene families in papaya ripening [53,88]. The specific binding of CpMADS4 and CpNAC3 to promoters of ethylene signal genes CpERF9 and CpEIL5 acts as a transcriptional activator in papaya ripening [54]. Similarly, TFs CpMYB1 and CpMYB2 had a negative regulatory role in ripening by suppressing the cell wall degradation genes such as CpPME1, CpPME2 and CpPG5 [55], whereas TFs CpSPLs guided by CpmiR156 were found to be involved in the ethylene signalling pathway [58] (Table 1).…”

The breeding of tropical fruit trees for improving fruit traits is complicated, due to the long juvenile phase, generation cycle, parthenocarpy, polyploidy, polyembryony, heterozygosity and biotic and abiotic factors, as well as a lack of good genomic resources. Many molecular techniques have recently evolved to assist and hasten conventional breeding efforts. Molecular markers linked to fruit development and fruit quality traits such as fruit shape, size, texture, aroma, peel and pulp colour were identified in tropical fruit crops, facilitating Marker-assisted breeding (MAB). An increase in the availability of genome sequences of tropical fruits further aided in the discovery of SNP variants/Indels, QTLs and genes that can ascertain the genetic determinants of fruit characters. Through multi-omics approaches such as genomics, transcriptomics, metabolomics and proteomics, the identification and quantification of transcripts, including non-coding RNAs, involved in sugar metabolism, fruit development and ripening, shelf life, and the biotic and abiotic stress that impacts fruit quality were made possible. Utilizing genomic assisted breeding methods such as genome wide association (GWAS), genomic selection (GS) and genetic modifications using CRISPR/Cas9 and transgenics has paved the way to studying gene function and developing cultivars with desirable fruit traits by overcoming long breeding cycles. Such comprehensive multi-omics approaches related to fruit characters in tropical fruits and their applications in breeding strategies and crop improvement are reviewed, discussed and presented here.
