Abstract Red peel color, a desirable trait in pears, is determined by anthocyanin accumulation. While REVEILLE (RVEs) transcription factors regulate biosynthesis some plant species, their role pear has not been well‐studied. This study investigates the function of RVEs ‘Zaosu’ (low content) and its red bud mutant, ‘Red Zaosu’ (high fruit peel. Consistent with higher content, pears exhibited increased PbRVE6 expression compared to ‘Zaosu’, while PbRVE3a PbRVE3b levels remained unchanged. Additionally, was localized nucleus. Overexpression pericarp significantly content upregulated key pathway genes PbANS PbUFGT . Conversely, VIGS silencing Palacer’ led decreased slight reduction content. Yeast one‐hybrid dual‐luciferase assays confirmed that can bind activate promoters These findings demonstrate promotes accumulation directly regulating expression. provides valuable foundation for understanding regulatory network anthocyanins peels, offers potential genetic resources production new germplasm.

Arbuscular Mycorrhizal (AM) symbiosis is integral to sustainable agriculture and enhances plant resilience abiotic biotic stressors. Through their symbiotic association with roots, AM improves nutrient water uptake, activates antioxidant defenses, facilitates hormonal regulation, contributing improved health productivity. Plants release strigolactones, which trigger spore germination hyphal branching, a process regulated by genes, such as D27 , CCD7 CCD8 MAX1 . recognition plants mediated receptor-like kinases (RLKs) LysM domains, leading the formation of arbuscules that optimize exchange. Hormonal regulation plays pivotal role in this symbiosis; cytokinins enhance colonization, auxins support arbuscule formation, brassinosteroids regulate root growth. Other hormones, salicylic acid, gibberellins, ethylene, jasmonic abscisic also influence colonization stress responses, further bolstering resilience. In addition health, soil improving microbial diversity, structure, cycling, carbon sequestration. This supports pH pathogen suppression, offering alternative chemical fertilizers fertility. To maximize ’s potential agriculture, future research should focus on refining inoculation strategies, enhancing compatibility different crops, assessing long-term ecological economic benefits. Optimizing applications critical for agricultural resilience, food security, farming practices.

Waxy maize (Zea mays L. sinensis kulesh) contains a lot of nutrients, and has long history cultivation extensive consumption. In this study, six waxy varieties white (J18 W2000), yellow (J41 J7), black (J10 J20) were selected as experimental materials, the functional nutrients differences in anthocyanin anabolic pathways kernels at 14, 18, 22, 26 days after pollination determined. The result show that kernel development stages had significant effect on carotenoid, soluble sugar, vitamin C, anthocyanin, mineral element content. higher content, which plays an important role coloration, whereas exhibit greater abundance elements. Furthermore, phenylalanine well activities ammonia lyase (PAL), chalcone isomerase (CHI), dihydroflavonol reductase (DFR), flavonoid 3-glucosyltransferase (UFGT), played biosynthetic pathway. conclusion, comprehensive quality decreased with delay stage, demonstrated superior quality. PAL CHI primary initial phase accumulation, while UFGT gradually assumed control subsequent stages.

Anthocyanins are flavonoid-derived metabolites that contribute to plant and human health. At present, few studies have studied the biosynthesis accumulation mechanism of anthocyanins in pepper leaves. The role CaMYBA–CaMYC–CaTTG1 complex anthocyanin leaves was studied. Yeast two-hybrid dual-luciferase experiments showed CaMYBA, CaMYC, CaTTG1 could form an MYB–bHLH–WD40 (MBW) complex. They also transcriptional activation on synthesis structural genes CaCHS , CaCHI CaF3H CaF3′5′H CaANS CaDFR CaUFGT . Silencing CaMYBA or CaMYC decrease content Transient overexpression tobacco indicated determines function MBW Further analysis activate expression by binding its promoter. Overall, our study expands understanding regulatory has important significance for creating more plants with different color patterns gene editing engineering.
