De novoassembly of the zucchini genome reveals a whole-genome duplication associated with the origin of theCucurbitagenus
2018
Summary The Cucurbita genus (squashes, pumpkins and gourds) includes important domesticated species such as C. pepo, C. maxima and C. moschata. In this study, we present a high-quality draft of the zucchini (C. pepo) genome. The assembly has a size of 263 Mb, a scaffold N50 of 1.8 Mb and 34 240 gene models. It includes 92% of the conserved BUSCO core gene set, and it is estimated to cover 93.0% of the genome. The genome is organized in 20 pseudomolecules that represent 81.4% of the assembly, and it is integrated with a genetic map of 7718 SNPs. Despite the small genome size, three independent lines of evidence support that the C. pepo genome is the result of a whole-genome duplication: the …
An SNP-based saturated genetic map and QTL analysis of fruit-related traits in Zucchini using Genotyping-by-sequencing
2016
[EN] Background: Cucurbita pepo is a cucurbit with growing economic importance worldwide. Zucchini morphotype is the most important within this highly variable species. Recently, transcriptome and Simple Sequence Repeat (SSR)- and Single Nucleotide Polymorphism (SNP)-based medium density maps have been reported, however further genomic tools are needed for efficient molecular breeding in the species. Our objective is to combine currently available complete transcriptomes and the Zucchini genome sequence with high throughput genotyping methods, mapping population development and extensive phenotyping to facilitate the advance of genomic research in this species. Results: We report the Genoty…
A Major QTL Located in Chromosome 8 of Cucurbita moschata Is Responsible for Resistance to Tomato Leaf Curl New Delhi Virus
2020
[EN] Tomato leaf curl New Delhi virus (ToLCNDV) is a bipartite whitefly transmitted begomovirus, responsible since 2013 of severe damages in cucurbit crops in Southeastern Spain. Zucchini (Cucurbita pepo) is the most affected species, but melon (Cucumis melo) and cucumber (Cucumis sativus) are also highly damaged by the infection. The virus has spread across Mediterranean basin and European countries, and integrated control measures are not being enough to reduce economic losses. The identification of resistance genes is required to develop resistant cultivars. In this assay, we studied the inheritance of the resistance to ToLCNDV previously identified in two Cucurbita moschata accessions. …

Phenotypic values of RILs carrying Zucchini and Scallop alleles in the detected QTL regions. Means and standard errors of the phenotypic value of RILs belonging to the alternative allelic classes (Zuchini versus Scallop) for the markers in the LOD peak regions of each significant QTL are shown. Data of the three environments, combined and separate, are shown to validate the effects of the different QTLs (Paip2014, Paip2015, and UPV2015). (DOCX 39 kb)

a) LOD peaks of the QTLs identified in the RIL population for vine, flowering and fruit traits. Lines represent the thresholds p 0.01 and 0.05. Results of CIM analysis with a 20 cM windows are shown for each trait. First box show QTL results with data from all the environments and the other three boxes show the QTL results for single environments Paip2014, Paip2015 and UPV2015. b) Means and errors of the phenotype of alternative allelic classes, homozygous Zucchini (AA) and homozygous Scallop (BB), are shown for each QTL, calculated with the full set of data and with the data form each environment separately. c) Genetic correlations (r x,y) between locations for each trait (*p

a) Genetic map developed using the GBS approach with the RIL population derived from the cross Zucchini x Scallop. The genetic and physical position of each of the the 7,718 SNP markers (in the C. pepo genome version 3.2) is indicated and the flanking sequenced of each SNPs is also included. b) Physical position and annotation (in the C. pepo genome version 3.2) of the SNPs that showed statistically significant distorted segregation. Chi-square p-values were corrected for multiple testing using Benjamini and Yekutieli correction [36]. Distorted SNPs are integrated with the 7,718 non-distorted SNPs used for the map construction for which the genetic position is also indicated. c) Main region…
