Genome Mapping and Molecular Breeding of Tomato
The cultivated tomato, Lycopersicon esculentum, is the second most consumed vegetable worldwide and a well-studied crop species in terms of genetics, genomics, and breeding. It is one of the earliest crop plants for which a genetic linkage map was constructed, and currently there are several molecular maps based on crosses between the cultivated and various wild species of tomato. The high-dens...
متن کاملHigh-Throughput Genomics Enhances Tomato Breeding Efficiency
Tomato (Solanum lycopersicum) is considered a model plant species for a group of economically important crops, such as potato, pepper, eggplant, since it exhibits a reduced genomic size (950 Mb), a short generation time, and routine transformation technologies. Moreover, it shares with the other Solanaceous plants the same haploid chromosome number and a high level of conserved genomic organiza...
متن کاملTomato Breeding Lines Resistant and Tolerant to Tomato Yellow Leaf Curl Virus Issued from Lycopersicon hirsutum.
ABSTRACT Two tomato yellow leaf curl virus (TYLCV)-resistant plants from accessions LA1777 and LA386 of the wild tomato species Lycopersicon hirsutum have been crossed. The resulting resistant F1 plants were crossed with the domesticated tomato L. esculentum, and a series of selfing was performed. At each generation, individuals were selected for resistance (no symptoms and undetectable viral D...
متن کاملTargeted recombination between homologous chromosomes for precise breeding in tomato
Homologous recombination (HR) between parental chromosomes occurs stochastically. Here, we report on targeted recombination between homologous chromosomes upon somatic induction of DNA double-strand breaks (DSBs) via CRISPR-Cas9. We demonstrate this via a visual and molecular assay whereby DSB induction between two alleles carrying different mutations in the PHYTOENE SYNTHASE (PSY1) gene result...
متن کاملBiotic and Abiotic Stress Responses in Tomato Breeding Lines Resistant and Susceptible to Tomato Yellow Leaf Curl Virus
In the eyes of a tomato grower, resistance to TYLCV, as opposed to susceptibility, is defined by the absence of, or mild, disease symptoms, and acceptable yield. In resistant cultivars and breeding lines, the amount of virus that can be detected with molecular tools is usually smaller than that in the susceptible plants, especially during the first 4 weeks after inoculation. Genetic studies hav...
