Extensive studies on heterosis in plants using transcriptome analysis have identified differentially expressed genes (DEGs) in F1 hybrids. However, it is not clear why yield in heterozygotes is superior to that of the homozygous parents or how DEGs are produced. Global allele-specific expression analysis in hybrid rice has the potential to answer these(More)
Plant architecture directly affects biomass in higher plants, especially grain yields in agricultural crops. In this study, we characterized a recessive mutant, plant architecture determinant (pad), derived from the Oryza sativa ssp. indica cultivar MH86. The mutant exhibited severe dwarf phenotypes, including shorter and stunted leaves, fewer secondary(More)
For heterozygous genes, alleles on the chromatin from two different parents exhibit histone modification variations known as allele-specific histone modifications (ASHMs). The regulation of allele-specific gene expression (ASE) by ASHMs has been reported in animals. However, to date, the regulation of ASE by ASHM genes remains poorly understood in higher(More)
Sec18p/N-ethylmaleimide-sensitive factor (NSF) is a conserved eukaryotic ATPase, which primarily functions in vesicle membrane fusion from yeast to human. However, the function of the OsSec18 gene, a homologue of NSF in rice, remains unknown. In the present study, we investigated the function of OsSec18 in rice and found that OsSec18 complements the(More)
