Summary: The study successfully engineered tomato fruit enriched in L-DOPA through overexpression of BvCYP76AD6, and further increased L-DOPA levels by elevating the expression of the metabolic master regulator MYB12. The research also revealed new roles for L-DOPA in plants, impacting fruit quality parameters and providing opportunities for the development of new biological sources of L-DOPA.

Summary: The regulation of endogenous hormones, including ABA and ethylene, plays a vital role in fruit ripening. This study applied RNAi to silence ABA receptor genes in tomato and identified specific receptors, such as SlRCAR11 and SlRCAR13, that participate in ABA signaling during tomato fruit ripening. Silencing these receptors weakened the ethylene biosynthesis and signaling pathway, leading to delayed fruit ripening, increased fruit firmness, and altered shelf-life and susceptibility to Botrytis cinerea. Interestingly, blocking ABA signaling did not affect the ability of ethylene to induce fruit ripening, suggesting that ABA signaling may be located upstream of ethylene signaling in regulating fruit ripening. Overall, this research provides new insights into the complex regulatory network of phytohormones in tomato fruit ripening.

Summary: Tomato has a short shelf life, but gamma irradiation can effectively delay its ripening and extend its storage period, as shown in this study. Gamma irradiation reduced microbial growth and decay of tomatoes, while also affecting their color and lycopene content. The underlying mechanism involves the upregulation of genes related to DNA and chloroplast repairs, as well as the downregulation of genes associated with ripening and carotenoid production.

Summary: This study discovered that the Silyc06g083580 gene plays an important role in tomato fruit development and softening. Gene-specific silencing of SlPL16 resulted in reduced pectate lyase enzyme activity, thicker pericarp, and lower soluble sugar content, while increasing fruit firmness and shelf life. Furthermore, the silencing of this gene led to a decrease in cell size and down-regulation of genes involved in cell wall degradation and pectin synthesis. Overall, this study highlights the significance of SlPL16 in tomato fruit softening and provides a potential target for genetic engineering to improve fruit storage tolerance.

Summary: The effect of isonicotinic acid (INA) in a chitosan (CS)/polyvinyl alcohol (PVA) blend was studied on ripening-dependent changes of preserved green tomatoes. Results showed that the CS/PVA/INA formulations could delay the changes in pigmentation parameters, firmness loss, malondialdehyde (MDA) and total polyphenol (TP) contents. The activities of peroxidase (POD), polyphenoloxidase (PPO), and phenylalanine ammonia-lyase (PAL) were also reduced by the CS/PVA/INA formulations. It was found that the CS/PVA blend had the highest TP content and antifungal activity against Alternaria alternata and Botrytis cinerea.

Summary: This study evaluated the effect of the Sletr1-2 mutant allele on flowering, fruit phenotype, shelf life, and yield-related traits in tropical tomatoes. The results showed that F1 mutants 'Intan' and 'Ratna' had a longer shelf life than the wild type, and the mutant allele had no side effects on other traits. Therefore, the Sletr1-2 allele has the potential to be used in tomato breeding programs in tropical countries.

Summary: High endogenous SA is associated with low ET evolution and high SL, while high lycopene content is correlated with high SA levels. Total antioxidants, PG, and PME decrease with fruit development, while lipid peroxidation increases. SlPAL4 and SlPAL6 genes play significant but opposite roles in regulating fruit ripening.

Summary: This study designed and synthesized a class of structurally simple AVG analogues, and molecular docking analysis revealed that compounds 2i, 2k, and 2n exhibited higher binding activity. Experimental results showed that 2i, 2k, and 2n could reduce ethylene production and delay postharvest ripening of tomatoes, with 2n being the most effective AVG analogue. This research provides a new approach for controlling ethylene action and extending the shelf life of fruits, and has significant implications for structure-activity relationship studies and the development of more functional AVG analogues.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
