Article Synopsis
- The study focuses on cold tolerance at the seedling stage (CTSS) in rice as a key trait for stable production in colder regions.
- Researchers developed 331 single nucleotide polymorphism (SNP) markers to identify quantitative trait loci (QTLs) associated with CTSS in a mapping population derived from a cold-tolerant wild rice and a sensitive variety.
- They identified three QTLs, with a significant locus (qCtss11) on chromosome 11 explaining about 40% of the phenotypic variation, and fine-mapped it to a 60-kb region containing six candidate genes, suggesting that certain genes may be responsible for CTSS.

Many transcriptional factors harboring the R2R3-MYB domain, basic helix-loop-helix domain, or WD40 repeats have been identified in various plant species as regulators of flavonoid biosynthesis in flowers, seeds, and fruits. However, the regulatory elements of flavonoid biosynthesis in underground organs have not yet been elucidated. We isolated the novel MYB genes IbMYB1 and IbMYB2s from purple-fleshed sweet potato (Ipomoea batatas L.

We searched for SNPs in 417 regions distributed throughout the genome of three Oryza sativa ssp. japonica cultivars, two indica cultivars, and a wild rice (O. rufipogon).
View Article and Find Full Text PDFA rice semidwarfing gene, sd-1, known as the "green revolution gene," was isolated by positional cloning and revealed to encode gibberellin 20-oxidase, the key enzyme in the gibberellin biosynthesis pathway. Analysis of 3477 segregants using several PCR-based marker technologies, including cleaved amplified polymorphic sequence, derived-CAPS, and single nucleotide polymorphisms revealed 1 ORF in a 6-kb candidate interval. Normal-type rice cultivars have an identical sequence in this region, consisting of 3 exons (558, 318, and 291 bp) and 2 introns (105 and 1471 bp).
