High-Resolution Mapping of a Fruit Firmness-Related Quantitative Trait Locus in Tomato Reveals Epistatic Interactions Associated with a Complex Combinatorial Locus    

Abstract: Fruit firmness in tomato (Solanum lycopersicum) is determined by a number of factors including cell wall structure, turgor, and cuticle properties. Firmness is a complex polygenic trait involving the coregulation of many genes and has proved especially challenging to unravel. In this study, a quantitative trait locus (QTL) for fruit firmness was mapped to tomato chromosome 2 using the Zamir Solanum pennellii interspecific introgression lines (ILs) and fine-mapped in a population consisting of 7,500 F2 and F3 l… Show more

“…Several reports have linked eQTLs to phenotypic variation in plants 30 ; however, in tomato only a few has been proposed [31][32][33] . Further experimentation allowed us to uncover that VTE3(1) eQTL is determined by differential methylation level of the wild and cultivated alleles.…”

“…These costs should be balanced with a proportionally higher energy intake (Agetsuma, 2001;Clymer, 2006;Oftedal, 1991). In general, fruits are high quality resources because they are easy to digest and rich in energy (Garber, 1998;Chapman et al, 2012), playing an important role in capuchins' diet (Izar et al, 2012). Fruits are, therefore, essential to increase the energy intake of juveniles and infants.…”

“…After the release of the watermelon genome (Guo et al , ), watermelon has become an ideal model crop for research on traits such as fruit cracking, size, shape, rind colour, and flesh texture due to being an annual and thus having a shorter life cycle than other perennial fruit crops. With the advancement of next‐generation sequencing (NGS) technology, sequencing‐based gene mining strategies, such as bulk segregant analysis (BSA), genetic mapping and genome‐wide association study (GWAS), have been widely used as affordable, efficient and routine approaches to dissect crop traits in rice (Wang et al , ) tomato (Chapman et al , ; Soyk et al , ), cucumber(Li et al , ; Xu et al , ), peanut(Luo et al , ), chickpea(Deokar et al , ),spinach(She et al , ), apple(Jia et al , ) and melon (Hu et al , ). Recently, genes or QTLs related to sugar transporter (Ren et al , ), dwarfism (Dong et al , ) and lobed leaves (Wei et al , ) have been reported in watermelon.…”
