title: Data from: Chromosomal loci important for cotyledon opening under UV-B in Arabidopsis thaliana

description: BACKGROUND: Understanding of the genetic architecture of plant UV-B
 responses allows extensive targeted testing of candidate genes or regions,
 along with combinations of those genes, for placement in metabolic or
 signal transduction pathways. RESULTS: Composite interval mapping and
 single-marker analysis methods were used to identify significant loci for
 cotyledon opening under UV-B in four sets of recombinant inbred lines. In
 addition, loci important for canalization (stability) of cotyledon opening
 were detected in two mapping populations. One candidate locus contained
 the gene HY5. Mutant analysis demonstrated that HY5 was required for
 UV-B-specific cotyledon opening. CONCLUSIONS: Structured mapping
 populations provide key information on the degree of complexity in the
 genetic control of UV-B-induced cotyledon opening in Arabidopsis. The loci
 identified using quantitative trait analysis methods are useful for
 follow-up testing of candidate genes.
