TL;DR: A 2275-marker genetic map of rice (Oryza sativa L.) covering 1521.6 cM in the Kosambi function has been constructed using 186 F2 plants from a single cross between the japonica variety Nipponbare and the indica variety Kasalath, and permitted us to characterize meiotic recombinations in the whole genome.
Journal ArticleDOI
Deletion in a gene associated with grain size increased yields during rice domestication
Ayahiko Shomura,Takeshi Izawa,Kaworu Ebana,Takeshi Ebitani,Hiromi Kanegae,Saeko Konishi,Masahiro Yano +6 more
TL;DR: Cl cloning of a newly identified QTL, qSW5 (QTL for seed width on chromosome 5), involved in the determination of grain width in rice found that a deletion resulted in a significant increase in sink size owing to an increase in cell number in the outer glume of the rice flower.
Journal ArticleDOI

TL;DR: The essentially complete sequence of chromosome 1, the longest chromosome in the rice genome, is reported and characteristics of the chromosome structure and the biological insight gained from the sequence are summarized.
Journal ArticleDOI
A 300 kilobase interval genetic map of rice including 883 expressed sequences.
Nori Kurata,Yoshiaki Nagamura,Kimiko Yamamoto,Yoshiaki Harushima,N Sue,Jianzhong Wu,Baltazar A. Antonio,Ayahiko Shomura,T Shimizu,Shaoyang Lin +9 more
TL;DR: A high resolution rice genetic map containing 1,383 DNA markers at an average interval of 300 kilobases is constructed, which is the first significant gene expression map in plants and the first to be backed up comprehensively by clone sequence data.
Journal ArticleDOI
Hd6, a rice quantitative trait locus involved in photoperiod sensitivity, encodes the α subunit of protein kinase CK2
TL;DR: Map-based cloning with advanced backcross progeny enabled us to identify a gene underlying a quantitative trait locus even though it exhibited a relatively small effect on the phenotype.
