In grapes, the number of flowers per inflorescence determines the compactness of grape bunches. Grape cultivars with tight bunches and thin-skinned berries easily undergo berry splitting, especially in growing areas with heavy rainfall during the grapevine growing season, such as Japan. We report herein that grape cytokinin oxidase/dehydrogenase 5 (VvCKX5) determines the number of berries per inflorescence in grapes.

- Koshu is a significant indigenous Japanese wine grape, distinct from European varieties, yet the details about its leaves and internodes' physiological traits are not well understood, which could enhance grape cultivation and wine quality.
- Through RNA sequencing, researchers identified 248 and 131 differentially expressed genes in Koshu leaves and internodes, respectively, with notable pathways linked to flavonoid biosynthesis and glutathione metabolism highlighted in Koshu's gene expression.
- These findings suggest that Koshu's unique traits contribute to its ability to produce beneficial flavonoids, making it well-suited to the Japanese environment.
glycosyl hydrolase family 17 (VvGHF17) is a grape apoplasmic β-1,3-glucanase, which belongs to glycosyl hydrolase family 17 in grapevines. β-1,3-glucanase is not only involved in plant defense response but also has various physiological functions in plants. Although expression is negatively related to the length of inflorescence in grapevines, the physiological functions of are still uncertain.

- - Previous studies indicate that intermittent cold stress (ICS) can lead to depression-like behaviors in mammals, and Tupaia belangeri (tree shrew) is highlighted as a relevant animal model due to its genetic similarities with humans and susceptibility to hepatitis B and C.
- - Young adult Tupaia exposed to ICS showed decreases in body temperature and weight, affirming their suitability for studying stress responses.
- - Treatment with a small-molecule compound, C737, effectively mitigated stress-induced weight loss in female Tupaia, outperforming the antidepressant agomelatine, suggesting potential insights into NRSF/REST's role in stress-related disorders.
