Abstract ：
In the life cycle of fruit, ripening is a crucial period for the formation of fruit quality. During this phase, a series of physiological and biochemical changes occur, leading to alterations in color and texture, softening, and the production of aroma volatiles. Relevant studies have demonstrated that ethylene-induced fruit ripening is a complex regulatory network involving numerous transcription factors, ethylene receptor protein families, signal transduction pathways, and downstream maturation-related genes. In this study, we conducted a genome-scale identification and characterization of long noncoding RNAs (lncRNAs) from the predominant AAA triploid banana cultivar, 'Tianbao-jiao', using rich RNA-sequencing (RNA-seq) datasets from fruit tissues treated with ethylene and untreated controls. This represents one of the first comprehensive investigations into banana lncRNAs associated with ripening. A total of 11,268 banana fruit lncRNAs were identified and found to be distributed across all banana chromosomes; similar to 76.1% of these lncRNAs were transcribed from intergenic regions. Banana fruit lncRNAs are relatively short, with 91.32% ranging from 100 to 1000 nucleotides in length. Most contain one or two exons, contrasting with protein-coding genes, which can have one to >= 10 exons. Compared with naturally ripened bananas, many lncRNAs exhibited significant differential expression in ethylene-treated banana fruits. Furthermore, downregulating the expression of lncRNA TCONS00507247 in the peel markedly inhibited the yellowing process. These findings suggest that lncRNAs play a vital role in regulating banana fruit ripening and offer new insights into fruit ripening research.

Abstract ：
Banana is a globally important food crop. As a large herbaceous plant with a shallow root system, its yield is highly susceptible to drought stress. ANP family genes play crucial roles in plant drought resistance. However, the ANP gene family has not been systematically studied in bananas, and how Piriformospora indica (P. indica) induces its expression remains unclear. A comprehensive identification of the ANP family is thus a necessary foundation for functional studies. In this study, we systematically identified 13 ANP family members in banana for the first time through genome-wide analysis. Using bioinformatics, RT-qPCR and subcellular localization techniques, we characterized their structural features, phylogenetic relationships, and the expression patterns of MaNPK1 under drought stress and P. indica colonization. The results revealed that banana ANP family members are highly evolutionarily conserved. MaNPK1-1 was specifically induced and upregulated by P. indica under drought conditions and subcellular localization showed that it played a role in the nucleus. This research provides theoretical insights into the function of the banana ANP family and its regulatory role in the P. indica mediated drought stress response, offering potential applications for breeding stress resistant banana varieties.

Abstract ：
This study conducted a genome-wide identification and systematic evolutionary analysis of the banana WRKY gene family using bioinformatics, transcriptomics, and molecular biology approaches. A total of 153 WRKY genes were identified in the banana genome, with significant differences in the amino acid count, molecular weight, and other physicochemical properties of their encoded proteins. The subcellular localization of these proteins is primarily in the nucleus. These genes are unevenly distributed across 11 chromosomes, with the highest density on chromosome 7. WRKY gene family members exhibit diverse expression patterns during fruit development and ripening, and some can respond to multiple abiotic and biotic stresses. Systematic evolutionary analysis classified them into three major groups (I, II, and III), with Group II having the highest number of members, which are further divided into five subgroups. Conserved motif analysis revealed that Motif1, Motif2, and Motif4 are key structural elements in the family's evolution, with some members having a WRKYGKK variant. The gene structure shows a wide range of exon numbers (1-22), and the promoter regions are rich in cis-elements related to light response, hormone signaling, and stress response, indicating their potential for integrating light signals, hormone networks, and multiple stress responses. Collinearity analysis identified 116 segmental duplication events, with Ka/Ks values all less than 1, indicating purifying selection. After ethylene treatment, 51 genes showed significant changes in expression, which can be categorized into four patterns: sustained upregulation, sustained downregulation, initial upregulation followed by downregulation, and delayed upregulation. Among these, MaWRKY10, MaWRKY88, and MaWRKY137 exhibited significant expression changes and may play key roles in fruit ripening. These findings significantly contribute to the theoretical framework regarding the evolution and function of the WRKY family in plants. Moreover, they offer valuable gene resources and regulatory strategies that enhance postharvest banana preservation and molecular breeding efforts.

Abstract ：
Strawberry Fusarium wilt, mainly caused by Fusarium oxysoporum f. sp. Fragariae (Fof), seriously threatens the yield and quality of strawberry. Piriformospora indica is an endophytic fungus that can colonise the roots of a wide range of plants, promoting plant growth and enhancing plant resistance. Against this background, the positive effects of P. indica on the growth of the daughter plants of 'Benihoppe' strawberry (Fragaria x ananassa Duch.) under Fof stress were investigated in this study. The study began by examining the inhibitory effect of P. indica on Fof growth through dual culture on agar plates. Subsequently, a symbiotic system between P. indica and strawberry plantlets was established, and the impact of P. indica on Fusarium wilt resistance and related physiological and biochemical indexes of the plantlets were evaluated. The results indicate that fungus colonization with P. indica significantly enhances the growth indices of strawberries, including plant height, petiole length, petiole diameter, and leaf area. Additionally, the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in the leaves of P. indica were increased, and the content of malondialdehyde (MDA) was decreased compared to those without colonization. Under the stress from Fof, the growth indexes of plant height, stem diameter, leaf area, petiole diameter, and root length of strawberry plants colonization with P. indica were significantly higher than those without colonization and the symptoms of wilting were relatively mild. The activities of SOD, POD, and CAT in roots and leaves of plants colonized with P. indica were significantly increased compared to those without colonization. Furthermore, the content of MDA in roots was decreased. These results suggested that P. indica could increase resistance to Fusarium wilt in strawberry by increasing the activity of antioxidant enzymes and reducing the content of MDA.

Abstract ：
Bananas (Musa spp.) are a popular tropical fruit grown worldwide and are typically harvested when 70% to 80% plump. Postharvest storage is crucial for maintaining fruit quality, with temperature playing a key role due to banana sensitivity to low temperatures. Red peeled bananas, such as the cultivar Hongmeiren, stand out for their unique red peel and pink pulp when ripe. These bananas offer nutritional benefits and are rich in anthocyanins compared with yellow bananas. This study focused on the hardness change, anthocyanin content, and the expression of related genes in red peeled bananas at different temperatures. Results showed that pulp hardness reached an edible state after 4 days at 19 and 25 degrees C, with stability thereafter. Storage time at 10 degrees C was longer and anthocyanin content remained stable across temperatures. Gene expression analysis indicated that genes including MaPAL, MaCHS, MaCHI, MaDFR, and MaANS related to anthocyanin synthesis were highly expressed at 10 degrees C, potentially preserving anthocyanin content and fruit appearance. Although higher anthocyanin content was observed at 19 and 25 degrees C, black spots appeared on the fruit peel after 8 days, affecting its quality. After 30 days of storage at 10 degrees C, a significant number of black spots appeared on the peel of the fruit, leading to a gradual loss of its nutritional value. This study indicates that red peeled bananas can be stored for longer periods while maintaining their appearance quality at 10 degrees C, as opposed to 19 and 25 degrees C. Hence, it is recommended to store red peeled bananas at low temperatures, especially following ethylene treatment or during periods of high temperatures.

Abstract ：
The red-flowered strawberry is a novel ornamental plant. This study aimed to assess the genetic diversity among ornamental strawberry germplasm resources. In this investigation, 17 red-flowered strawberry germplasms and 1 white-flowered strawberry germplasm were analyzed for genetic diversity and genetic relationships using a combination of phenotypic data, inter-simple sequence repeats (ISSR), and conserved DNA-derived polymorphism (CDDP) molecular markers. The results indicated that the 18 strawberry germplasms exhibited significant variability and genetic diversity at both phenotypic and molecular levels. The clustering results revealed notable differences between phenotypic clustering and molecular marker clustering, while the ISSR and CDDP markers grouped into broadly similar clusters. We further consolidated the ISSR and CDDP marker data to conduct the cluster analysis and population structure analysis of the 18 strawberry germplasms. The cluster analysis classified these germplasms into four clusters at a genetic similarity coefficient of 0.77. The population structure analysis categorized the germplasms into three groups, with 88.89% exhibiting a Q value >= 0.6, and 11.11% demonstrating a Q value < 0.6. This finding suggests that the genetic background of the 18 strawberry germplasms is relatively homogeneous. Notably, 'Summer Breeze-Rose' and 'Summer Breeze-Cherry' possess relatively complex genetic backgrounds (Q < 0.6). Furthermore, the floral, foliar, and plant traits of both germplasms display significant ornamental value and can serve as vital resources for the development and utilization of ornamental strawberries, as well as for the selection and breeding of new varieties.
