Genetic and molecular regulation of fruit and plant domestication

Domestication traits often seem to be controlled by independent mutations at orthologous loci (Paterson et al., 1995), although this observation does not hold true in all cases (Li and Gill, 2006). The lack of detailed genome sequences and functional analysis of genes at the selected loci limits a t ...

(Chaubet et al., 1992; Robertson et al., 1996; Waterborg, 1992); however, the expression patterns of these variants have not been elucidated and the precise number of histone variants that exist remains unclear, even in the model plant Arabidopsis. This is probably because many of the histone varian ...

Quantitative trait locus

A quantitative trait locus (QTL) is a section of DNA (the locus) that correlates with variation in a phenotype (the quantitative trait). The QTL typically is linked to, or contains, the genes that control that phenotype. QTLs are mapped by identifying which molecular markers (such as SNPs or AFLPs) correlate with an observed trait. This is often an early step in identifying and sequencing the actual genes that cause the trait variation.Quantitative traits are phenotypes (characteristics) that vary in degree and can be attributed to polygenic effects, i.e., the product of two or more genes, and their environment.
