We have characterized a rice (Oryza sativa) dwarf mutant, dwarf11 (d11), that bears seeds of reduced length. To understand the mechanism by which seed length is regulated, the D11 gene was isolated by a map-based cloning method. The gene was found to encode a novel cytochrome P450 (CYP724B1), which showed homology to enzymes involved in brassinosteroid (BR)(More)
Dierent languages sometimes use dierent acoustic manners to transmit the same kind of linguistic information. This fact lets us easily suppose that learners tend to transmit the information in a manner of not a language to learn but their native language. While English word accent i s linguistically almost the same as Japanese one, the word accent(More)
We have been focusing on applying speech technologies to pronunciation learning. In our previous study[1], a stressed syllable detector was implemented by using stressed syllable HMMs and unstressed ones. And using the detector internally, several systems were implemented[2]. However, their development did not necessarily require the use of HMMs as an(More)
In order to estimate whether mastoparan 7 specifically activates plant heterotrimeric G proteins, comparisons were made between the responses of a rice normal cultivar and a rice dwarf mutant, Daikoku dl, which has a mutation in the gene of the a subunit of a heterotrimeric G protein, to mastoparan 7. First, we found that mastoparan 7 induced the activity(More)
Magnaporthe oryzae, the fungus causing rice blast disease, should contend with host innate immunity to develop invasive hyphae (IH) within living host cells. However, molecular strategies to establish the biotrophic interactions are largely unknown. Here, we report the biological function of a M. oryzae-specific gene, Required-for-Focal-BIC-Formation 1(More)
