Project description:Genotyping arrays are tools for high throughput genotyping, which is required in genome-wide association studies (GWAS). Since the first cucumber genome draft was reported, genetic maps were constructed mainly based on simple-sequence repeats (SSRs) or on combinations of SSRs and other sequence-related amplified polymorphism (SRAP). In this study we developed the first cucumber genotyping array which consisted of 32,864 single nucleotide polymorphisms (SNPs). These markers cover the cucumber genome every 2.1Kb and have parents/F1 hybridizations as a training set. The training set was validated with Fludigm technology and had 98% concordance. The application of the genotyping array was illustrated by constructed a genetic map of 600 cM in length based on recombinant inbred lines (RIL) population of a 9930XGy14 cross of which compromise of 11564 SNPs. The markers collinearity between the genetic map and genome references of the two parents estimated as R2=0.97. Moreover, this comparison supports a translocation in the beginning of chromosome 5 that occurred in the lineage of 9930 and Gy14 as well as local variation in the recombination rate. We also used the array to investigate the local allele frequencies along the cucumber genome and found specific region with segregation distortions. We believe that the genotyping array together with the training set would be a powerful tool in applications such as quantitative-trait loci (QTL) analysis and GWAS.

Project description:Cucumber (Cucumis sativus L.) fruit is a type of fleshy fruit that is harvested immaturely. Early fruit development directly determines the final fruit length and diameter, and consequently the fruit yield and quality. Different cucumber varieties display huge variations of fruit length, but how fruit length is determined at the molecular level remains poorly understood. To understand the genes and gene networks that regulate fruit length in cucumber, high throughout RNA-seq data were used to compare the transcriptomes of early fruit from two near isogenic lines with different fruit lengths. 3955 genes were found to be differentially expressed, among which 2368 genes were significantly up-regulated and 1587 down-regulated in the line with long fruit. Microtubule and cell cycle related genes were dramatically activated in the long fruit, and transcription factors were implicated in the fruit length regulation in cucumber. Thus, our results built a foundation to dissect the molecular mechanism of fruit length control in cucumber, a key agricultural trait of significant economic importance.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of gene expression profiles of cucumber under short-term chilling stress. The goals of this study are to transcriptome analysis of cucumber leaves under chilling stress. Methods: mRNA profiles of seedlings exposed to an air temperature of 6°C in the absence of light at 0, 2, 6, and 12 h were generated by deep sequencing, in triplicate, using Illumina Hiseq platform. The reference genome and gene model annotation files were downloaded from the genome website （http://cucurbitgenomics.org/）. An index of the reference genome was built using Bowtie v.2.2.3 and paired-end clean reads were aligned to the reference genome using TopHat v.2.0.12. qRT–PCR validation was performed using SYBR Green assays. Results: A total of 55.7 million clean reads was generated. Based on the threshold values of absolute value of log2 ratio ≥ 1 and FDR ≤ 0.05, a total of 2113 DEGs was identified at three time points (2, 6, and 12 h). A total of 30 genes was detected at all time points. The number of DEGs increased with time. In total, 100 TFs from 22 families in three subsets were detected. And 19 kinase families were identified in three subsets. The DEGs identified by RNA sequencing were confirmed by qRT-PCR analysis, indicating that the data were reliable. These findings provide information that can be useful for investigating the molecular mechanisms underlying the response to chilling stress in cucumber and other plants. Conclusions: The results presented here reveal changes in the transcriptome profile of cucumber in response to chilling stress. Exposure to a low temperature induced genes involved in hormone regulation, lipid metabolism, and photosynthesis, including NAC, WRKY, AP2/ERF, ERD, MYB as well as zinc finger TFs and protein kinases such as receptor-like protein kinase, MAPK, and CDK. Most TFs were upregulated whereas CDKs were downregulated. These findings provide information that can be useful for investigating the molecular mechanisms underlying the response to chilling stress in cucumber and other plants.

Comparative analysis of fruit from two near-isogenic lines, 408 (long fruit) and 409 (short fruit), was employed to discover genes and networks that regulate the fruit length. Two biological replicates were used from each line.

Project description:The carpel number (CN) is an important fruit trait affecting fruit shape, size, and internal quality in cucumber. CsCLAVATA3 (CsCLV3) was previously showed to be the simply inherited gene responsible for carpel number variation in cucumber, but the molecular mechanism of CsCLV3 regulating carpel number remains elusive. Here, we found that the expression of CsCLV3 was negatively correlated with carpel number variation in different cucumber lines. Knock down of CsCLV3 by RNAi led to increased number of petals and carpels, suggesting that CsCLV3 functions as a negative regulator for floral organ number in cucumber. WUSCHEL (WUS) has been well characterized to promote CLV3-expressing stem cell activity in a non-cell autonomous manner to regulate meristem maintenance and floral organ number. However, here we found the expression region of CsCLV3 overlaps with CsWUS in the basal domain of meristem, and CsCLV3 interact with CsWUS at the protein level through binding to the WUS-box motif. Overexpression of CsFUL1, a FRUITFULL-like MADS-box gene involved in fruit length regulation, resulted in increased number of floral organs in cucumber. Biochemical analyses indicated that CsFUL1 can directly bind to CsWUS promoter to stimulate its expression. Further, we found that auxin participates in carpel number variation in cucumber through physical interaction of AUXIN RESPONSE FACTOR 14 (CsARF14) and CsWUS. Therefore, CsFUL1 and CsARF14 are two new players in the WUS-CLV pathway in determining carpel number variation in cucumber.

Project description:Colletotrichum orbiculare Whi2, yeast stress response Whi2 homolog, is involved in switch from biotrophic to necrotrophic stage. To elucidate downstream genes regulated by Co Whi2, we have conducted DNA microarray. About 3100 genes were up or down regulated in the Co whi2Î mutant compared with the wild-type. In particularly, 44 genes among up-regulated 58 genes in the Co whi2Î mutant are ribosomal protein related gene. Eukaryote is widely conserved TOR (Target Of Rapamycin) which is known to regulator of ribosomal gene expression. To elucidate whether up-regulated ribosomal genes in the Co whi2Î mutant are regulated by TOR activity, we have conducted DNA microarray in the Co whi2Î mutant treated with rapamycin inhibiting TOR activity. The enormous ribosomal gene expression in the Co whi2Î mutant treated with the rapamycin is lower than that without rapamycin treatment. In gene expression of the Co whi2Î mutant, the wild-type and the Co whi2Î mutant infecting on cucumber cotyledons were assessed at 4 hours post-inoculation. In gene expression of the Co whi2Î mutant with rapamycin treatment, Co whi2Î mutant treated with 100nM rapamycin and Co whi2Î mutant without rapamycin treatment infecting on cucumber cotyledons were assesed at 4 hours post-inoculation. Four replication were performed for each experiments.
