Summary: Understanding grapevine reproductive processes is crucial for managing yield and quality, especially in clones with contrasting seed content. Genetic analysis revealed differences between seedless variants and normal seeds, suggesting potential traceability markers for improved propagation. Meiotic anomalies likely contribute to seedlessness, with identified single nucleotide polymorphisms as possible functional candidates for the seedless phenotype.

Summary: The study highlights the importance of complex N-glycan maturation for normal plant responses, especially in fruit-bearing crops like tomato. RNA interference targeting GNTI and MANII in tomato plants revealed severe impairments in growth and fruit development, suggesting the crucial role of N-glycan modification in plant physiology.

Summary: Ethylene can stimulate plant respiration and generate heat. The experiments showed that by spraying ultra-low concentrations of ethylene precursors onto grapevines prone to poor fruit set, the fruit set can be improved and crop losses can be reduced.

Summary: DNA acetylation plays a role in regulating gene expression during plant development, including in grapes. In this study, 'Kyoho' grapes treated with a deacetylase inhibitor were used to investigate the effects of acetylation. The results showed that acetylation positively regulated phenylalanine metabolism and flavonoid biosynthesis pathways. The research also revealed the interactions between transcription factors and histone deacetylases, highlighting the importance of histone modification in anthocyanin biosynthesis and grape ripening.

Summary: Transcriptomics and metabolomics are increasingly used in molecular studies of grapevine to understand plant and fruit development, as well as interactions with the environment. Integrating these methods can help improve fruit quality and stress resistance in breeding programs. Despite generating vast amounts of data, integrated transcriptome/metabolome meta-analyses have not been fully accomplished in this species due to specificities of metabolomic studies.

Summary: This study reveals the regulatory mechanisms of ethylene in the ripening of non-climacteric grapevine berries. Ethylene treatment stimulates fruit color, anthocyanin accumulation, ABA biosynthesis, and sugar accumulation, while inhibiting cellulose synthesis and promoting pectin degradation. The study also confirms the involvement of ethylene biosynthesis and signaling genes in fruit ripening.

Summary: Due to climate change, the sugar content of grapes in Hungary has increased, leading to disharmonious wines with high alcohol content. Experiments in grape canopy management were conducted over four years to delay ripening and reduce sugar content. Results showed a significant reduction in grape juice sugar yield in both cultivars, while other parameters were minimally affected.

Summary: Roots are important for the growth and development of plants, and auxin is involved in regulating root development. The BS gene is involved in root development and may regulate it through auxin signaling. This study found that the BS gene can restore the shorter primary roots and higher density of lateral roots in a mutant Arabidopsis plant. The BS gene may also upregulate the expression of certain genes involved in auxin signaling by directly binding to their promoter.

Summary: This study evaluated the polyphenol composition, content, and antioxidant capacity of grape skin extracts at five key ripening stages, identifying potential markers for distinguishing ripening stages. Results showed significant differences in polyphenol accumulation at different stages, with an increasing trend in total phenolic content, total flavonoid content, and antioxidant capacity during ripening. Analysis of polyphenolic compounds identified catechin, quercetin-3-O-glucoside, and resveratrol-3-O-glucoside as potential markers for distinguishing ripening stages.

Summary: The ripening stage of grapes plays a crucial role in determining the phenolic and volatile compounds in red wines, with higher maturity levels leading to increased levels of key secondary metabolites. Late-harvested grapes result in wines with higher content of certain compounds, while extending ripening to sugar concentrations beyond 22 degrees Brix improves the biochemical profile and health-related benefits of aged wine.

Summary: Glycosylation is a crucial protein modification that affects cellular processes such as differentiation, development, and immune response. Research focuses on its role in plant development, analyzing tools, and literature regarding fruit ripening. More studies on protein glycosylation are needed to clarify its specific role in posttranslational processes and its impact on normal fruit development and ripening.

Summary: Cold stress inhibits banana fruit ripening by affecting the softening and de-greening processes. The mechanism of ripening disorder caused by chilling injury (CI) in banana fruit is largely unknown. MaIAA17-like gene was found to be involved in fruit softening and de-greening in 'Fenjiao' banana.
