    Abstract: The Cucurbitaceae (cucurbit) family consists of about 1,000 species in 95 genera, including many economically important and popular fruit and vegetable crops. During the past several years, reference genomes have been generated for & gt;20 cucurbit species, and variome and transcriptome profiling data have been rapidly accumulated for cucurbits. To efficiently mine, analyze and disseminate these large-scale datasets, we have developed an updated version of Cucurbit Genomics Database. The updated database, CuGenDBv2 (http://cucurbitgenomics.org/v2), currently hosts 34 reference genomes from 27 cucurbit species/subspecies belonging to 10 different genera. Protein-coding genes from these genomes have been comprehensively annotated by comparing their protein sequences to various public protein and domain databases. A novel ‘Genotype’ module has been implemented to facilitate mining and analysis of the functionally annotated variome data including SNPs and small indels from large-scale genome sequencing projects. An updated ‘Expression’ module has been developed to provide a comprehensive gene expression atlas for cucurbits. Furthermore, synteny blocks between any two and within each of the 34 genomes, representing a total of 595 pair-wise genome comparisons, have been identified and can be explored and visualized in the database.

    Abstract: How raffinose (Raf) family oligosaccharides, the major translocated sugars in the vascular bundle in cucurbits, are hydrolyzed and subsequently partitioned has not been fully elucidated. By performing reciprocal grafting of watermelon (Citrullus lanatus) fruits to branch stems, we observed that Raf was hydrolyzed in the fruit of cultivar watermelons but was backlogged in the fruit of wild ancestor species. Through a genome-wide association study, the alkaline alpha-galactosidase ClAGA2 was identified as the key factor controlling stachyose and Raf hydrolysis, and it was determined to be specifically expressed in the vascular bundle. Analysis of transgenic plants confirmed that ClAGA2 controls fruit Raf hydrolysis and reduces sugar content in fruits. Two single-nucleotide polymorphisms (SNPs) within the ClAGA2 promoter affect the recruitment of the transcription factor ClNF-YC2 (nuclear transcription factor Y subunit C) to regulate ClAGA2 expression. Moreover, this study demonstrates that C. lanatus Sugars Will Eventually Be Exported Transporter 3 (ClSWEET3) and Tonoplast Sugar Transporter (ClTST2) participate in plasma membrane sugar transport and sugar storage in fruit cell vacuoles, respectively. Knocking out ClAGA2, ClSWEET3, and ClTST2 affected fruit sugar accumulation. Genomic signatures indicate that the selection of ClAGA2, ClSWEET3, and ClTST2 for carbohydrate partitioning led to the derivation of modern sweet watermelon from non-sweet ancestors during domestication.

    Abstract: NAC (NAM, ATAF1/2, and CUC2) transcription factors play important roles in fruit ripening and quality. The watermelon genome encodes 80 NAC genes, and 21 of these NAC genes are highly expressed in both the flesh and vascular tissues. Among these genes, ClNAC68 expression was significantly higher in flesh than in rind. However, the intrinsic regulatory mechanism of ClNAC68 in fruit ripening and quality is still unknown. In this study, we found that ClNAC68 is a transcriptional repressor and that the repression domain is located in the C-terminus. Knockout of ClNAC68 by the CRISPR-Cas9 system decreased the soluble solid content and sucrose accumulation in mutant flesh. Development was delayed, germination was inhibited, and the IAA content was significantly decreased in mutant seeds. Transcriptome analysis showed that the invertase gene ClINV was the only gene involved in sucrose metabolism that was upregulated in mutant flesh, and expression of the indole-3-acetic acid-amido synthetase gene ClGH3.6 in the IAA signaling pathway was also induced in mutant seeds. EMSA and dual-luciferase assays showed that ClNAC68 directly bound to the promoters of ClINV and ClGH3.6 to repress their expression. These results indicated that ClNAC68 positively regulated sugar and IAA accumulation by repressing ClINV and ClGH3.6. Our findings provide new insights into the regulatory mechanisms by which NAC transcription factors affect fruit quality and seed development.

    First Report of the L993S Mutation in the Voltage-Gated Sodium Channel in Field Populations of the German Cockroach Blattella germanica

    Abstract: The long-term and frequent use of pyrethroid insecticides has led to the development of pyrethroid resistance in many insect populations around the world. Specific mutations in the voltage-gated sodium channel (VGSC) have been well documented to be responsible for knockdown resistance (kdr) to pyrethroids and dichlorodiphenyltrichloroethane (DDT) in a variety of arthropods. However, reports regarding naturally occurring kdr mutation in field populations of the German cockroach Blattella germanica (Linnaeus) (Dictyoptera: Blattellidae) in China have remained scarce. In this study, a survey was conducted to detect the presence and frequency of kdr mutations in field populations of B. germanica across Neijiang, Sichuan province of China. In addition to the previously reported L993F mutation, a new amino acid substitution L993S was discovered for the first time. Overall, the classical 993F was the dominant allele with frequencies ranging from 61.8 to 89.6%, while the frequencies of the novel L993S mutation were in the range between 2.5 and 15.0%. Notably, high frequencies (50.0–79.2%) of resistant homozygotes were detected in our samples, indicating high levels of pyrethroid resistance in these B. germanica populations. The results suggest that alternative insecticides with a mode of action different from pyrethroids should be considered in the control of German cockroaches in these regions.

    Abstract: The 8th edition of the American Joint Committee on Cancer (AJCC) staging system for medullary thyroid cancer (MTC) was implemented in 2018. However, its ability to predict prognosis remains controversial. Patients and Methods Patient data were obtained from the Surveillance, Epidemiology, and End Results (SEER) database and multicenter datasets. Overall survival was the primary end-point of the present study. The concordance index (C-index) was used to assess the efficacy of various models to predict prognostic outcomes. Results A total of 1450 MTC patients were selected from the SEER databases and 349 in the multicenter dataset. According to the AJCC staging system, there were no significant survival differences between T4a and T4b categories (P = .299). The T4 category was thus redefined as T4a’ category (≤3.5 cm) and T4b’ category ( & gt;3.5 cm) based on the tumor size, which was more powerful for distinguishing the prognosis (P = .003). Further analysis showed that the T category was significantly associated with both lymph node (LN) location and count (P & lt; .001). Therefore, the N category was modified by combining the LN location and count. Finally, the above-mentioned novel T and N categories were adopted to modify the 8th AJCC classification using the recursive partitioning analysis principle, and the modified staging system outperformed the current edition (C-index, 0.811 vs. 0.792). Conclusions The 8th AJCC staging system was improved based on the intrinsic relationship among the T category, LN location, and LN count, which would have a positive impact on the clinical decision-making process and appropriate surveillance.

    Abstract: The purpose of this study is to explore whether social relationships of family and school contexts mediate the influence of socioeconomic status (SES) on Chinese adolescents’ mental health. Methods A school-based study was conducted among a sample aged 13–18 in East China (n = 6902). We used scales for measuring social relationships and self-rated mental health. Family SES was computed from subjective socioeconomic status, education and occupation of parents. The mediation model was tested by using Path Analysis in IBM SPSS-Amos. Results The results showed that SES can significantly influence adolescent mental health through parent–child relationship, student–teacher relationship and student–student relationship. The total effect, direct effect and total indirect effect were −0.209 (95% CI = −0.299, −0.136), −0.090 (95% CI = −0.174, −0.007), −0.119 (95% CI = −0.187, −0.078) for boys, and −0.337 (95% CI = −0.478, −0.230), −0.132 (95% CI = −0.283, 0.010), −0.205 (95% CI = −0.351, −0.085) for girls. Conclusion The link between SES and adolescent mental health can be explained by social relationships. Focusing on the parent–child, student–student and student–teacher relationship interventions may contribute to improving the mental health of Chinese adolescents, especially in low socioeconomic groups, as well as female students.
