“…Decreased SSC indicates a reduction in total sugars, which probably results from pulp cell metabolism and microbial activity instead of firmness loss. Similar results were presented in a paper on a study of litchi storage quality under RT [ 22 ]. In addition to sugars, the content of acids also exerts a profound impact on fruit flavors.…”

As a popular form of fruit consumption, fresh-cut watermelon is of great convenience for its consumers. Owing to the lack of comprehensive knowledge about the quality changes of fresh-cut watermelon during its shelf life, guidelines and standards are unavailable currently. To clarify the deterioration process and its underlying mechanism in fresh-cut watermelon, the sensory parameters, metabolomics, and microbial community of fresh-cut watermelon during a three-day storage at both room temperature (RT) and refrigerator temperature were systematically studied in this work. Results revealed that the whole property of the watermelon stored at refrigerator temperature kept stable, while pulps stored at RT had substantially deteriorated after 36 h. The decay was reflected in the significant decrease in soluble solid contents, firmness, pH, and color parameters in the sensory perspective. At the metabolic level, significantly declined malate, citrate, uridine, uridine 5-monophosphate, and amino acids, and increased ethanol and lactate contents, were observed as deterioration markers, which partially resulted from the activities of pyruvate dehydrogenase and alcohol dehydrogenase and the burst of genera Enterobacteriaceae and Leuconostocaceae. This study unveiled the underlying mechanisms of quality changes in fresh-cut watermelon under its primary storage conditions to provide fundamental information and potential clues for its quality control and preservation.

“…However, multi-omics and integrated approach is required for detailed mechanistic understanding of key aspects of postharvest treatments and storage on fruit. In this regard, the multi-omics approach was reported for ‘Feizixiao’ litchi fruit by Guo et al (2022 , for ‘Jingtian No.3′ green bell pepper by Fu et al (2022) , for ‘Hayward’ Kiwifruit fruit by Tian et al (2021) , and for apple by Yan et al (2022). These studies provided detailed insight into the molecular mechanism related to the changes in fruit quality.…”

On another study, multi-omics approaches used to reveal the effect of room temperature storage for litchi fruit quality by Guo et al (2022) . Most of the above studies highlighted that the integrated omics approach provides a better knowledge to understand various molecular mechanisms at the whole genome level.…”

“…is one of the most popular tropical and subtropical fruit in the international market for its outstanding nutritional profile, exotic flavor, and appealing color (Hu et al., 2022). However, the fruit is particularly vulnerable to senescence after harvest, resulting in a short shelf life and reduced market value (Guo et al., 2022; Jiang et al., 2017). It has been documented that low energy under hypoxia triggers the expression of SnRK1α and enhances the translation of energy metabolism‐related genes by activating the expression of bZIP63 .…”

Cellular energy status is a key factor deciding the switch-on of the senescence of horticultural crops. Despite the established significance of the conserved energy master regulator sucrose non-fermenting 1 (SNF1)related protein kinase 1 (SnRK1) in plant development, its working mechanism and related signaling pathway in the regulation of fruit senescence remain enigmatic. Here, we demonstrate that energy deficit accelerates fruit senescence, whereas exogenous ATP treatment delays it. The transient suppression of LcSnRK1a in litchi (Litchi chinensis Sonn.) fruit inhibited the expression of energy metabolism-related genes, while its ectopic expression in tomato (Solanum lycopersicum) promoted ripening and a high energy level. Biochemical analyses revealed that LcSnRK1a interacted with and phosphorylated the transcription factors LcbZIP1 and LcbZIP3, which directly bound to the promoters to activate the expression of DARK-INDUCIBLE 10 (LcDIN10), ASPARAGINE SYNTHASE 1 (LcASN1), and ANTHOCYANIN SYNTHASE (LcANS), thereby finetuning the metabolic reprogramming to ensure energy and redox homeostasis. Altogether, these observations reveal a post-translational modification mechanism by which LcSnRK1a-mediated phosphorylation of LcbZIP1 and LcbZIP3 regulates the expression of metabolic reprogramming-related genes, consequently modulating litchi fruit senescence.
