Monitoring rice anther proteome expression patterns during pollen development
Rice (Oryza sativa L.) pollen grains are highly sensitive to extreme temperatures. Studies on the proteomic analysis of pollen at different developmental stages are limited. In this study, to identify proteins ex...

Analysis of complete chloroplast genome sequence of Korean landrace Cymbidium goeringii
The complete chloroplast genome sequence of Korean Cymbidium goeringii acc. smg222 was analyzed. Based on a comparison with Chinese C. goeringii, losses of nine ndh subunits (ndhA, ndhB, ndhC, ndhD, ndhE, ndhF, n...

Genome-wide association study reveals candidate genes related to low temperature tolerance in rice (Oryza sativa) during germination
In this study, relative germination percentage (RGP) and delayed mean germination time (DMGT) were measured in various rice accessions at the germination stage and carried out association analysis to identify ...

Quantitative shotgun proteomic analysis of cold-stressed mature rice anthers
Rice crops are vulnerable to low temperatures. During development, the reproductive stage is particularly sensitive to cold exposure, which causes abnormal pollen development and a high degree of male sterilit...

Open AccessDefining the genome structure of `Tongil' rice, an important cultivar in the Korean "Green Revolution"
Tongil (IR667-98-1-2) rice, developed in 1972, is a high-yield rice variety derived from a three-way cross between indica and japonica varieties. Tongil contributed to the self-sufficiency of staple food producti...

Open AccessAnalysis of segregation distortion and its relationship to hybrid barriers in rice
Segregation distortion (SD) is a frequently observed occurrence in map** populations generated from crosses involving divergent genotypes. In the present study, ten genetic linkage maps constructed from reci...

A novel HSI2 mutation in Arabidopsis affects the PHD-like domain and leads to derepression of seed-specific gene expression
Two related B3 domain transcriptional repressors, HSI2 (HIGH-LEVEL EXPRESSION OF SUGAR-INDUCIBLE GENE2)/VAL1 (VP1/ABI3-LIKE1) and HSL1 (HSI2-LIKE1)/VAL2, function redundantly to repress key transcriptional reg...

Fine map** and candidate gene analysis of dense and erect panicle 3, DEP3, which confers high grain yield in rice (Oryza sativa L.)
Architecture of the rice inflorescence, which is determined mainly by the morphology, number and length of primary and secondary inflorescence branches, is an important agronomical trait. In the current study,...

Xyloglucan endotransglycosylase/hydrolase genes in cotton and their role in fiber elongation
Plant cell wall extensibility is mediated, in part, by xyloglucan endotransglycosylases/hydrolases (XTH) that are able to cleave and reattach xyloglucan polymers that make up the hemicelluloses matrix of type ...

Map-based cloning of the ERECT PANICLE 3 gene in rice
Panicle architecture in rice can have a strong influence on yield. Using N-methyl-N-nitrosourea mutagenesis, we isolated an erect panicle mutant, Hep, from Hwasunchalbyeo, a glutinous japonica rice cultivar. Gene...

High-resolution map** of two rice brown planthopper resistance genes, Bph20(t) and Bph21(t), originating from Oryza minuta
Brown planthopper (BPH) is one of the most destructive insect pests of rice. Wild species of rice are a valuable source of resistance genes for develo** resistant cultivars. A molecular marker-based genetic ...

Fine map** and candidate gene analysis of hwh1 and hwh2, a set of complementary genes controlling hybrid breakdown in rice
Hybrid breakdown (HB), a phenomenon of reduced viability or fertility accompanied with retarded growth in hybrid progenies, often arises in the offspring of intersubspecific hybrids between indica and japonica in...
