The pattern of senescence was studied by following the changes in chlorophyll and protein in the leaves and by measuring (32)P retention and export from source to sink during development of the rice plant (Oryza sativa L. cv. Jaya) subjected to different manipulative treatments. With the advance of reproductive development, the chronological sequence of leaf senescence was changed, so that the ...
Transfer rRNAs are important molecules responsible for the translation event during protein synthesis. tRNAs are widespread found in unicellular to multi-cellular organisms. Analysis of tRNA gene family members in Oryza sativa revealed the presence of 750 tRNA genes distributed unevenly in different chromosomes. The length of O. sativa tRNAs genes were ranged from 66 to 91 nucleotides encoding ...
Rice (Oryza sativa) tiller angle is a key component for achieving ideal plant architecture and higher grain yield. However, the molecular mechanism underlying rice remains elusive. We characterized novel mutant lazy2 (la2) isolated causative gene LA2 through map-based cloning. Biochemical, genetic studies were conducted to elucidate LA2-involved regulatory mechanism. The la2 shows large with im...
We examined the relationship between morphological characteristics of anthers and fertility in japonica rice cultivars subjected to high temperature (37.5(26 degrees C day/night) at flowering. Percentage fertility was negatively correlated with the number of cell layers that separated the anther locule from the lacuna that formed between the septum and the stomium. The cell layers consisted of ...
The ongoing international efforts of the Rice Genomic Sequencing Project have already generated a large amount of sequence data. The next important challenge will be to construct saturation mutant lines for the functional analysis of all of the genes revealed by this effort in the context of the rice plant as a whole. Recently, the endogenous retrotransposon Tos17 has been shown to be an effici...
The OsCPK4 gene is a member of the complex gene family of calcium-dependent protein kinases in rice (Oryza sativa). Here, we report that OsCPK4 expression is induced by high salinity, drought, and the phytohormone abscisic acid. Moreover, a plasma membrane localization of OsCPK4 was observed by transient expression assays of green fluorescent protein-tagged OsCPK4 in onion (Allium cepa) epiderm...
A polar gibberellin active in the dwarf rice (Oryza sativa L.) seedling and barley (Hordeum vulgare L.) half-seed assays was extracted from immature sour cherry (Prunus cerasus L.) seed and identified as gibberellin A(32) by gas-liquid chromatography and selected ion monitoring.

Tilletia horrida is the most destructive fungal pathogen of rice (Oryza sativa L.). The 20,105,270-bp draft genome sequence of T. horrida strain QB-1 is reported here. Genes encoding proteins associated with key virulence factors were predicted, and this can provide information for understanding the pathogenic mechanisms in T. horrida.
