Summary: In kiwifruit, the transcriptional regulation of ethylene biosynthesis is different between leaves and fruit after mechanical wounding. Ethylene biosynthesis in fruit is accompanied by transcriptional increases in ACS, ACO, and NAC TFs, while in kiwifruit leaves, wound-specific transcriptional increases are largely absent, suggesting post-transcriptional control mechanisms are more important. The NAC TFs AcNAC2-4 regulate both system-1 and -2 ethylene biosynthesis in fruit through control of AcACS1 expression levels, but not in leaves where post-transcriptional/translational regulatory mechanisms may prevail.

Summary: Ethylene regulates fruit ripening by impacting the expression of ripening-associated genes, with AdMsrB1 identified as a key gene responsive to ethylene in kiwifruit. Overexpression of AdMsrB1 leads to increased free Met and ACC levels, ultimately enhancing ethylene production. The expression of AdMsrB1 is modulated by ethylene-inducible transcription factors AdNAC2 and AdNAC72.

Summary: Methyl jasmonate (MeJA) plays an important role in the tolerance mechanisms of rice against arsenic (As) stress, protecting the rice from As-induced toxicity and improving its defense systems. The positive effects of MeJA on carbohydrate metabolism, photosynthesis, and growth under As stress are the result of its interaction with ethylene biosynthesis, reducing oxidative stress-induced cellular injuries and cell deaths.

Summary: A kiwifruit ripeness indicator using potassium permanganate was developed. Kiwifruit was packaged in polypropylene containers with different cover films and stored at different temperatures. The gas permeability of the cover films, kiwifruit firmness, ethylene gas concentration, and indicator color were measured. The indicator changed color when the fruit reached a certain firmness, indicating its ripeness.

Summary: Cold stress negatively affects the growth, yields, and fruit quality of tomato plants. This study reveals the role of a ethylene response factor, SlERF.B8, in regulating jasmonate biosynthesis in tomato under cold stress. SlERF.B8 is transcriptionally enhanced by JA and cold stress, and silencing of SlERF.B8 leads to decreased JA accumulation and reduced cold tolerance. Additionally, SlERF.B8 acts as a transcriptional activator for JA biosynthesis genes and is regulated by the JA signaling mediator MYC2, forming a positive feedback loop.

Summary: The application of exogenous jasmonate can stimulate ethylene production and improve fruit quality, but over-ripening leads to fruit crop losses. However, using 1-methylcyclopropene can suppress fruit ripening. In this study, it was found that exogenous jasmonate had the most impact on lipid metabolism in tomatoes.

Summary: MeJ and Ur foliar applications have been studied to improve grape quality, and it was found that MeJ application enhanced terpenoids and C6 compounds synthesis while decreasing alcohols content. The combined MeJ + Ur treatment reduced benzenoids and alcohols and did not affect C-13-norisoprenoids content. The season had a strong influence on all volatile compounds except terpenoids.

Summary: This study found that the change in flesh color of yellow-fleshed kiwifruit is highly correlated with chlorophyll degradation-related genes, especially three chlorophylla/b-binding protein (CAB) genes and one stay-green gene (AcSGR1), while no correlation was found with carotenoid-related genes. The results suggest the important role of chlorophyll degradation in the coloration of 'Jinshi NO.1' and provide potential candidates for further functional characterization and transcriptional regulation.

Summary: Chilling injury is a barrier to kiwifruit refrigeration, but understanding the molecular basis of the cold response in refrigerated kiwifruit is crucial. The study identified 81 bZIP family proteins in kiwifruit and revealed that the expression of AREB/ABF family members is induced by low temperature and ABA. Ectopic expression of AchnABF1 enhances cold tolerance in plants and is involved in osmotic stress response.

Summary: Fresh fruits and vegetables are important dietary sources, but post-harvest processing often leads to quality deterioration. Salicylic acid, as a non-toxic alternative, plays a critical role in preserving post-harvest quality by delaying fruit ripening, improving color, and reducing browning.

Summary: Anthocyanins play a role as visual signals for pollination and seed dispersal, and fruits containing anthocyanins are attractive to consumers due to their appearance and health benefits. This study comprehensively identified contributors to anthocyanin accumulation in kiwifruit using transcriptome and small RNA high-throughput sequencing. The results showed that the differential expression and subsequent repression of MYB activators, as well as the regulation by miRNA, are responsible for the variation in anthocyanin accumulation in kiwifruit species.

Summary: The study demonstrates that exogenous ASA treatment significantly reduces ethylene production and inhibits the activity of related enzymes in kiwifruit tissues. Transcriptome analysis and transcription factor screening reveal ASA-responsive regulators for ethylene biosynthetic genes. Additionally, abundantly expressed genes are found in both ASA-treated and control tissues. The findings suggest that ASA inhibits ethylene biosynthesis by regulating protein activity at a post-transcriptional level.

Summary: This study evaluated the efficacy of acetylsalicylic acid (ASA) in preserving the quality and delaying the ripening process of fresh-cut (FC) kiwifruit. ASA treatment maintained better fruit appearance and higher fruit firmness, while reducing mass loss, total soluble solids, and ethylene production. Gene analysis and dual-luciferase assays showed that ASA-responsive transcription factors regulated fruit quality-related genes, resulting in delaying ripening process and extending the shelf-life of FC kiwifruit.
