Abstract ：
Overaccumulation of lignin (a physiological disorder known as granulation) often occurs during fruit ripening and postharvest storage in pomelo (Citrus grandis). It causes an unpleasant fruit texture and taste. Previous studies have shown that lignin metabolism is closely associated with the process of juice sacs granulation. At present, the underlying transcriptional regulatory mechanisms remain unclear. In this study, we identified and isolated a candidate NAC transcription factor, CgNAC043, that is involved in the regulation of lignin biosynthesis in Citrus grandis, which has homologs in Arabidopsis and other plants. We used the fruit juice sacs of 'San hong' as the material, the staining for lignin with HCl-phloroglucinol of fruit juice sacs became dark red from the various developmental stages at 172 to 212 days post anthesis (DPA). The RT-qPCR was used to analyze the gene expression of CgNAC043 and its target gene CgMYB46 in fruit sacs, it was found that the expression trend of CgNAC043 was basically same as CgMYB46, which increased gradually and peaked at 212 DPA. The expression level of CgNAC043 in juice sacs obtained away from the core was the lowest, while those near the core and granulated area were highly expressed. The transcriptional activation activity of CgNAC043 and CgMYB46 was analyzed by a yeast two-hybrid system, with only CgNAC043 showing transcriptional activation activity in Y2H Gold yeast. A transformation vector, p1301- CgNAC043, was transformed into the mesocarp of 'San hong' by Agrobacterium-mediated transformation. Results showed that the expression of transcription factors CgMYB58 and CgMYB46 are all upregulated. Further experiments proved that CgNAC043 not only can directly trans-activate the promoter of CgMYB46 but also trans-activate the promoters for the lignin biosynthesis-related genes CgCCoAOMT and CgC3H by dual luciferase assay. We isolated the CgNAC043 gene in pomelo and found CgNAC043 regulates target genes conferring the regulation of juice sacs granulation.

Abstract ：
Juice sac granulation (a physiological disorder) leads to large postharvest losses of pomelo (Citrus maxima). Previous studies have shown that juice sac granulation is closely related to lignin accumulation, while the molecular mechanisms underlying this disorder remain elusive in pomelo. Our results showed that the lignin content in NC (near the core) and FC (far away from the core) juice sacs overall increased from 157 DPA (days post anthesis) to 212 DPA and reached a maximum at 212 DPA. Additionally, the lignin content of NC juice sacs was higher than that of FC juice sacs. In this study, we used transcriptome-based weighted gene co-expression network analysis (WGCNA) to address how lignin formation in NC and FC juice sacs is generated during the development of pomelo. After data assembly and bioinformatic analysis, we found a most correlated module (black module) to the lignin content, then we used the 11 DEGs in this module as hub genes for lignin biosynthesis. Among these DEGs, PAL (phenylalanine ammonia lyase), HCT (hydroxycinnamoyl-CoA shikimate/quinate hydroxycinnamoyl transferase), 4CL2 (4-coumarate: CoA ligase), C4H (cinnamate 4-hydroxylase), C3 ' H (p-coumarate 3-hydroxylase), and CCoAOMT1 (caffeoyl CoA 3-Omethyltransferase) were the most distinct DEGs in granulated juice sacs. Co-expression analysis revealed that the expression patterns of several transcription factors such as MYB, NAC, OFP6, and bHLH130 are highly correlated with lignin formation. In addition, the expression patterns of the DEGs related to lignin biosynthesis and transcription factors were validated by qRT-PCR, and the results were highly concordant with the RNA-seq results. These results would be beneficial for further studies on the molecular mechanism of lignin accumulation in pomelo juice sacs and would help with citrus breeding.

Abstract ：
In the present study, the fruit physiology and sugar-acid ratio of 24 pomelo cultivars grown in ten different locations of the subtropical region of China were measured. The contents of soluble sugars and organic acids were quantified using high-performance (HPLC-MS) and ultra-performance liquid chromatography-mass spectrometry (UPLC-MS), respectively. The results revealed that the physiological and basic quality attributes of 24 pomelo cultivars, including fruit weight, fruit width, fruit length, peel thickness, number of segments, pulp weight, pulp color, soluble solids, and Vitamin C, ranged between 264.63-1945.85 g, 8.60-19.56 g, 7.40-20.70 g, 0.46-3.33 mm, 11-18.66, 210.25-1351.66 g, 8.59-15.14 Brix degrees, and 34.79-84.58 mg/100 g, respectively. Soluble sugars, i.e., fructose, glucose, and sucrose, ranged between 16.25-24.25, 16.17-24.22, and 19.90-55.28 mg/g, respectively. Similarly, Organic acids, i.e., pyruvate, fumaric acids, succinic acid, tartaric acid, quinic acid, citric acid, malic acid, and cis-aconitic acid, in 24 pomelo cultivars ranged between 0.48-1.84, 0.02-0.45, 0-0.05, 0.01-0.1, 0-0.14, 3.01-11.85, 0.18-1.42, and 0.01-0.16 mg/g, respectively. The pomelo cultivars 'Hongzuanmi', 'Minihong', and 'Hangwanmi' exhibited maximum contents of citric acid and pyruvate and showed ultimately excessive organic acids. Overall, the 'Guanximi' and its budding cultivars, i.e., 'Hongroumi', 'Huangjinmi', and 'Sanhongmi', had the best quality fruits having maximum sugar-acid ratio. Correlation analysis showed that total soluble sugars had a significantly positive correlation with sucrose contents, while citric acids, malic acid, and pyruvate were positively correlated with total organic acids. The determined sugar-acid profile of pomelo cultivars provides the basis for future elucidation of key mechanisms regulating sugars and acids biosynthesis in pomelo.

Abstract ：
14-3-3 proteins (14-3-3s) are among the most important phosphorylated molecules playing crucial roles in regulating plant development and defense responses to environmental constraints. No report thus far has documented the gene family of 14-3-3s in Citrus sinensis and their roles in response to stresses. In this study, nine 14-3-3 genes, designated as CitGF14s (CitGF14a through CitGF14i) were identified from the latest C. sinensis genome. Phylogenetic analysis classified them into epsilon-like and non-epsilon groups, which were supported by gene structure analysis. The nine CitGF14s were located on five chromosomes, and none had duplication. Publicly available RNA-Seq raw data and microarray databases were mined for 14-3-3 expression profiles in different organs of citrus and in response to biotic and abiotic stresses. RT-qPCR was used for further examining spatial expression patterns of CitGF14s in citrus and their temporal expressions in one-year-old C. sinensis "Xuegan" plants after being exposed to different biotic and abiotic stresses. The nine CitGF14s were expressed in eight different organs with some isoforms displayed tissue-specific expression patterns. Six of the CitGF14s positively responded to citrus canker infection (Xanthomonas axonopodis pv. citri). The CitGF14s showed expressional divergence after phytohormone application and abiotic stress treatments, suggesting that 14-3-3 proteins are ubiquitous regulators in C. sinensis. Using the yeast two-hybrid assay, CitGF14a, b, c, d, g, and h were found to interact with CitGF14i proteins to form a heterodimer, while CitGF14i interacted with itself to form a homodimer. Further analysis of CitGF14s co-expression and potential interactors established a 14-3-3s protein interaction network. The established network identified 14-3-3 genes and several candidate clients which may play an important role in developmental regulation and stress responses in this important fruit crop. This is the first study of 14-3-3s in citrus, and the established network may help further investigation of the roles of 14-3-3s in response to abiotic and biotic constraints.

Abstract ：
Temperature is an important environmental factor for plant growth and development. Temperature affects various physiological processes and is especially important for bud development; however, it remains unclear how temperature affects the progress of bud differentiation in Ntazetta var. chinensis. In this study, histological analysis and cultivation observation were performed on the main buds of Narcissustazetta var. chinensis bulbs that stored at different temperatures. It was found that a temperature of 25 degrees C was required for the flower bud differentiation of N.tazetta var. chinensis. Comparatively, the temperature range required for the formation of leaf buds was relatively broad. Leaf buds could be formed at all temperatures of 15 degrees C, 25 degrees C, and 35 degrees C. However, at 15 degrees C and 35 degrees C, the leaf buds could form but these plants did not bloom during the cultivation. A 5 degrees C storage temperature completely blocked the formation of leaf buds and the differentiation of flower buds, and only roots were formed and no leaves or scapes were detected. This indicates that different storage temperatures resulted in major differences in the growth and development of Ntazetta var. chinensis. The overall findings suggest that storage temperature controlling is an effective approach to regulate the bud development of N.tazetta var. chinensis.

Abstract ：
Citrus peels have health-promoting effects and are a rich source of antioxidant substances. This study evaluated the compositions of phenolic compounds and antioxidant activities in the peels of 52 citrus varieties with consistent planting time and management. The highest levels of total phenols (72.95 +/- 37.60 mg/g DW) and total flavonoids (71.43 +/- 37.64 mg/g DW) were found in mandarin. The highest phenolic acid content (18.78 +/- 0.38 mg/g DW), dominated by protocatechuic acid, was found in kumquat. The antioxidant potency composite index was 6.23-94.56, suggesting mandarin varieties HJ, TWPG, TTPG, AY28, BZH and TCJC had the highest antioxidant activity. Statistics analysis indicated phenolic compounds and antioxidant activity were positively correlated. Principal component analysis and hierarchical cluster analysis suggested a strong relationship between phenolic compound composition and genetic background. This study indicated significant differences in the biological properties of various types of citrus peels; which are valuable for future utilization and research of citrus peels.
