How the brain selects goals for movements remains unknown. The system designed to move the eyes rapidly, the saccadic system, may play a role. Here we ask how sensory signals within a saccade area are influenced by selecting and preparing a saccade. Trained monkeys made or withheld saccades, based on a color cue, to targets varying in luminance contrast. We(More)
The rice OsMADS16 gene is phylogenetically related to the angiosperm B-function MADS-box genes. To investigate if OsMADS16 functions as an AP3/DEF orthologue to regulate the development of lodicules and stamens in rice, we isolated its genomic sequences and characterized its functions in planta by RNA interference. The genomic sequence of the OsMADS16 gene(More)
Floral organ identity is defined by organ homoetic genes whose coordinated expression is crucial with respect to the time and place of floral organ formation. Here, we report molecular cloning and characterization of the rice STAMENLESS 1 (SL1) gene that is involved in floral development. The sl1 mutant largely resembles the rice B-class gene mutant spw1;(More)
DNA-binding with one finger (Dof) proteins are a large family of transcription factors involved in a variety of biological processes in plants. In rice, 30 different Dof genes have been identified through genome analysis. Here we report the functional characteristics of a rice Dof gene, OsDof12, which encodes a predicted Dof protein. The nuclear(More)
By using a whole-genome oligonucleotide microarray, designed based on known and predicted indica rice genes, we investigated transcriptome profiles in developing leaves and panicles of superhybrid rice LYP9 and its parental cultivars 93-11 and PA64s. We detected 22,266 expressed genes out of 36,926 total genes set collectively from 7 tissues, including(More)
MicroRNA319 (miR319) family is one of the conserved microRNA (miRNA) families among diverse plant species. It has been reported that miR319 regulates plant development in dicotyledons, but little is known at present about its functions in monocotyledons. In rice (Oryza sativa L.), the MIR319 gene family comprises two members, Osa-MIR319a and Osa-MIR319b.(More)
In addition to its role in saccade generation, the superior colliculus (SC) is involved in target selection, saccade selection, and shifting the focus of spatial attention. Here, we investigated the influence of saccade selection on sensory interactions within single response fields (RFs) of SC neurons. One or two differently shaped stimuli were presented(More)
Rice blast, caused by Magnaporthe oryzae, is one of the most devastating diseases. The two major subspecies of Asian cultivated rice (Oryza sativa L.), indica and japonica, have shown obvious differences in rice blast resistance, but the genomic basis that underlies the difference is not clear. We performed a genomewide comparison of the major class of(More)
The shape of grass leaves possesses great value in both agronomy and developmental biology research. Leaf rolling is one of the important traits in rice (Oryza sativa L.) breeding. MYB transcription factors are one of the largest gene families and have important roles in plant development, metabolism and stress responses. However, little is known about(More)
Orexins, also termed hypocretins, consist of two neuropeptide agonists (orexin A and B) interacting with two known G-protein coupled receptors (OX(1)R and OX(2)R). In addition to other biological functions, the orexin-2 receptor is thought to be an important modulator of sleep and wakefulness. Herein we describe a series of novel, selective OX(2)R(More)
