Genetic diversity of a germplasm collection of Cucurbita pepo using SRAP and AFLP markers
Cucurbita pepo is a highly polymorphic species. The cultivars can be grouped into eight morphotypes in two subspecies, ssp. pepo and ssp. ovifera. A collection of 69 accessions representative of the
The genome of melon (Cucumis melo L.)
The data suggest that transposon amplification may in part explain the increased size of the melon genome compared with the close relative cucumber, and a low number of nucleotide-binding site–leucine-rich repeat disease resistance genes were annotated, suggesting the existence of specific defense mechanisms in this species.
Viral diseases causing the greatest economic losses to the tomato crop. II. The Tomato yellow leaf curl virus — a review
An updated review of these new approaches on virus transmission, molecular biology, variability, diagnostic methods, and potential ways to control TYLCV will lead to a better understanding of the virus-vector-host relationships, key factors in the adoption of disease control measures.
Transcriptome characterization and high throughput SSRs and SNPs discovery in Cucurbita pepo (Cucurbitaceae)
The first broad survey of gene sequences and allelic variation in C. pepo is presented, where limited prior genomic information existed, and the transcriptome provides an invaluable new tool for biological research.
Evaluation of whitefly-mediated inoculation techniques to screen Lycopersicon esculentum and wild relatives for resistance to Tomato yellow leaf curl virus
It is concluded that artificial cage inoculation, although more time-consuming, is the most efficient, adequate, and reliable technique to screen both cultivated and wild Lycopersicon species for resistance to TYLCV.
Relationships, origin, and diversity of Galapagos tomatoes: implications for the conservation of natural populations.
Three forms of L. cheesmanii that are of interest to breeders because of their distinctive morphology and habitat preferences are distinguished, and a previously unreported invasive wild red-fruited form, which was found on the island of Santa Cruz, is named L. esculentum 'Gal cer,' likely of recent origin.
Variation Revealed by SNP Genotyping and Morphology Provides Insight into the Origin of the Tomato
Tomato, Solanum lycopersicum, is divided into two widely distributed varieties: the cultivated S. lycopersicum var. lycopersicum, and the weedy S. lycopersicum var. cerasiforme. Solanum
Classification and phylogenetic relationships in Solanum section Lycopersicon based on AFLP and two nuclear gene sequences
According to the data presented, the recently proposed species, S. corneliomulleri, is indistinguishable from S. peruvianum s.str, and both the sequence and the AFLP trees suggest that S. arcanum could represent a complex of populations composed of two cryptic species.
The gene pat-2, which induces natural parthenocarpy, alters the gibberellin content in unpollinated tomato ovaries.
The pat-2 mutation may increase GA 20-oxidase activity in unpollinated ovaries, leading to a higher synthesis of GA(20), the precursor of an active GA.
