Based on gene expression profiling data obtained using the NSF45K, we concluded that the four unique genes (1a, 1b, 1c, and 3) and the three predominantly light-responsive candidate genes (2-1, 5-2, and 7-1) would be good targets for studying the biological functions of genes involved in rice chloro ...

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.
