Summary: This study identified and characterized the ripening inducing factor FaRIF in strawberry, which plays a crucial role in controlling key ripening-related processes such as fruit softening, pigment and sugar accumulation. Functional analyses through stable transgenic lines showed that FaRIF is a key regulator of strawberry fruit ripening from early developmental stages, controlling various metabolic pathways and the balance of aerobic/anaerobic metabolism. This research suggests that FaRIF is a potential target for genetic modifications to enhance the quality of strawberry fruits.

Summary: This study revealed the functional cross-regulation of miR5290 and FaMADS1 in ABA-mediated ripening of strawberry fruit. ABA could promote the expression of miR5290 and inhibit the expression of FaMADS1, thus accelerating anthocyanin biosynthesis and fruit ripening.

Summary: The study compared the responses of fruit quality, anthocyanin content, and gene expression in 'Seolhyang' and 'Jukhyang' strawberry cultivars at different maturity stages and during postharvest shelf life. Fruit dimensions increased then decreased during shelf life, with 'Jukhyang' showing higher soluble solids content and titratable acidity. Different phenotypic responses were observed between the two cultivars in terms of fruit color, phenolic compounds, anthocyanins, and gene expression.

Summary: This study investigated the effect of light intensity and spectrum on anthocyanin accumulation in purple-fruited Capsicum genotypes. The results showed that increasing the blue light fraction can increase anthocyanin levels and delay fruit ripening. Transcriptome analysis also revealed that fruits illuminated with higher blue light fractions expressed fewer genes related to ripening and senescence.

Summary: Transposition of transposable elements can affect the expression, splicing, epigenetic status, and function of genes located near the inserted/excised locus. In grape, the presence of the Gret1 retrotransposon in the promoter region of the VvMYBA1a allele suppresses the expression of the VvMYBA1 transcription factor gene, resulting in the green berry skin color of the 'Shine Muscat' grape cultivar in Japan. By targeting Gret1 with CRISPR/Cas9, we successfully eliminated the transposon in 19 out of 45 transgenic plants, demonstrating the potential for transposon removal through genome editing.

Summary: This study revealed that the bud mutant RM from Red Delicious apple had significantly higher total anthocyanin content compared to the original strain OS. Metabolomics analysis found that cyanidin-3-O-galactoside was significantly accumulated in the fruit skin of RM. Transcriptome analysis showed up-regulation of the structural gene MdF3H and transcription factor MdMYB66 in the mutant. Overexpression of MdMYB66 promoted anthocyanin accumulation and increased the expression of related structural genes. The findings suggest that MdMYB66 regulates anthocyanin metabolism by precise gene expression regulation, providing insight into the biosynthesis and regulation of anthocyanins.

Summary: The metabolome of strawberries at harvest determines their storage capacity. Dynamics of volatile production during storage of strawberries grown under different drainage ratios were evaluated. Various non-target VOCs analysis showed that aldehydes content decreased over the storage period, while the esters and furanones increased as aroma compounds in strawberry ripening. The release of VOCs linked to fruit decay was delayed in the groups given relatively little water. Changes in firmness, total soluble solid content, anthocyanin content, and antioxidant activity supported the slower over-ripening tendency of the groups with less water. The study demonstrated that preharvest drainage changes during cultivation affected fruit quality during strawberry storage, and optimal drainage ratio could delay stress and senescence, ensuring strawberry yield. VOCs could be considered an early indicator for strawberry fruit shelf-life.

Summary: The transcription factor FvRIF, phosphorylated by FvMAPK6, plays a key role in regulating strawberry fruit ripening by targeting genes involved in various aspects of ripening. Knockout mutations of FvRIF result in a complete block of fruit ripening. FvRIF modulates anthocyanin biosynthesis and fruit softening by directly regulating the related core genes, while its activity is regulated by phosphorylation modification by FvMAPK6.

Summary: Plants produce chemical defenses to poison or deter insect herbivores, but these defenses may also affect the beneficial endosymbionts of the herbivores. This study found that rice produces an antifungal flavonoid phytoalexin in response to attack by a pest, which inhibits the pest's beneficial endosymbionts.

Summary: In recent years, outbreaks of the Eurasian spruce bark beetle have caused significant damage to conifer forests in Europe. The ability of these insects to kill mature trees is attributed to mass attacks on the host tree and the presence of fungal symbionts. The role of chemical communication in maintaining the fungal symbiosis is poorly understood. This study shows that the fungal symbionts metabolize spruce resin monoterpenes and produce oxygenated derivatives that act as cues for the beetles to locate breeding sites with beneficial symbionts.

Summary: Considerable advances in strawberry genetics and genomics have allowed the identification of genetic variants responsible for fruit color variation. Strawberry fruits obtain their appealing red color through the accumulation of water-soluble pigments called anthocyanins. This article explores our understanding of fruit color formation in strawberries and how recent developments, such as high-throughput genotyping and high-quality reference genomes, have facilitated the identification of causal genetic variants. The completion of haplotype-resolved genomes combined with QTL mapping will further enhance the study of genetic diversity in fruit color and its translation into strawberry improvement.

Summary: Conifer trees increase production of terpene resins in response to herbivores or pathogens, but studying this in the lab is challenging. This study demonstrates that cell cultures of Norway spruce can be a convenient system for studying terpene induction in this species, showing similar but lower levels of monoterpene accumulation compared to intact trees. Treatment with hormones and fungal elicitors increased monoterpene accumulation through increased biosynthesis, suggesting the potential of using cell cultures for studying terpene resin defenses.

Summary: By studying the dynamics of plant defense and counter-defense, this study theoretically derived the conditions under which preemptive counter-defense reduces exposure to isothiocyanates (ITCs) compared to direct counter-defense. The models explain how herbivory transfers glucosinolates (GLSs) from plants to insect guts and describe the dynamics of ITCs in the gut during feeding with the two types of counter-defenses. The results show that herbivores with preemptive counter-defense are usually less exposed to ITCs.

Summary: Light is an important environmental signal for plant defense. In this study, it was found that the transcription factor BBX29 integrates light signaling with defense responses in Arabidopsis. BBX29 promotes the accumulation of flavonoids, sinapate, and glucosinolates in leaves, which are important for plant defense. Genetic evidence indicated that BBX29 up-regulates the expression of key genes involved in flavonoid and glucosinolate biosynthesis. Knockout mutants of bbx29 displayed reduced expression of these genes and increased susceptibility to pathogens and herbivores, while BBX29 overexpression lines showed the opposite. BBX29 also played a role in mediating the effects of UV-B radiation on plant defense.
