Fruit set is a key stage in determining yield potential and guaranteeing quality formation and regulation. N-(2-chloro-4-pyridyl)-N'-phenylurea (CPPU) has been widely applied in grape production, the most iconic of which is the promotion of grape fruit set. However, current studies still lack the molecular mechanism of CPPU-induced grape fruit set.

Currently, the JmjC domain-containing proteins have been reported in many species; however, they have not been systematically studied in grapes. In this paper, 21 VviJMJ gene family members were identified from the whole grape genome, and the VviJMJ genes were classified into five subfamilies: KDM3, KDM4, KDM5, JMJD6, and JMJ-only based on the phylogenetic relationship and structural features of Arabidopsis and grape.

- The RING C3H2C3 type is a significant subfamily of ubiquitin ligases that influence plant growth and responses to different stresses, with 143 genes identified in grapevine.
- Phylogenetic analysis categorized these genes into eleven groups, revealing that their expansion is primarily due to tandem duplications, and most have few introns suggesting structural similarities.
- The study demonstrated that one gene, VyRCHC114, enhances drought tolerance in Arabidopsis when overexpressed, improving plant survival and activating key stress response genes.
Article Synopsis
- VvPPR1 is a DYW-type PPR protein crucial for leaf morphogenesis in Jingxiu grape, influencing leaf rolling, anthocyanin accumulation, and trichome formation.
- The protein features 15 PPR motifs with a targeted chloroplast site and is predominantly expressed in grape leaves, localizing in the cytoplasm and chloroplast.
- Overexpression of VvPPR1 in plants leads to distinct phenotypic changes, indicating its potential as a target for enhancing horticultural crop cultivation.
Article Synopsis
- - The E3 ubiquitin ligase VlPUB38 is crucial for plant growth, specifically by regulating abscisic acid (ABA) synthesis and influencing fruit ripening processes in plants like grapes and strawberries.
- - Overexpression of VlPUB38 in strawberries led to a delay in fruit maturity, but this was alleviated when exogenous ABA or a proteasome inhibitor (MG132) was applied.
- - VlPUB38 targets the enzyme abscisic-aldehyde oxidase (VlAAO) for degradation via the 26S proteasome, indicating that it plays a negative regulatory role in fruit ripening by controlling ABA levels.
Background: Hypermethylation of gene promoters has been regarded as an epigenetic regulator for gene inactivation in the development of several diseases. In the current study, we aimed to explore how long noncoding RNA X-inactive specific transcript (lncRNA XIST) function in collagen degradation in chondrocytes of osteoarthritis (OA) after tibial plateau fracture by regulating tissue inhibitor of metalloproteinase-3 (TIMP-3) promoter methylation.
Methods: In silico analysis was used to screen differentially expressed lncRNAs in cartilage tissues of OA.
