The GS3 locus located in the pericentromeric region of rice chromosome 3 has been frequently identified as a major QTL for both grain weight (a yield trait) and grain length (a quality trait) in the literature. Near isogenic lines of GS3 were developed by successive crossing and backcrossing Minghui 63 (large grain) with Chuan 7 (small grain), using Minghui(More)
Crop domestications are long-term selection experiments that have greatly advanced human civilization. The domestication of cultivated rice (Oryza sativa L.) ranks as one of the most important developments in history. However, its origins and domestication processes are controversial and have long been debated. Here we generate genome sequences from 446(More)
BACKGROUND With the availability of rice and sorghum genome sequences and ongoing efforts to sequence genomes of other cereal and energy crops, the grass family (Poaceae) has become a model system for comparative genomics and for better understanding gene and genome evolution that underlies phenotypic and ecological divergence of plants. While the genomic(More)
Cis- natural antisense transcripts (cis- NATs) are RNAs transcribed from the antisense strand of a gene locus, and are complementary to the RNA transcribed from the sense strand. Common techniques including microarray approach and analysis of transcriptome databases are the major ways to globally identify cis- NATs in various eukaryotic organisms.(More)
A huge amount of cDNA and EST resources have been developed for cultivated rice species Oryza sativa; however, only few cDNA resources are available for wild rice species. In this study, we isolated and completely sequenced 1888 putative full-length cDNA (FLcDNA) clones from wild rice Oryza rufipogon Griff. W1943 for comparative analysis between wild and(More)
PURPOSE To describe the clinical and genetic findings in one Chinese family with autosomal recessive retinitis pigmentosa (arRP) and in three unrelated Chinese families with Usher syndrome type II (USH2). METHODS One family (FR1) with arRP and three unrelated families (F6, F7, and F8) with Usher syndrome (USH), including eight affected members and seven(More)
Cold tolerance at the early seedling stage of rice is one of the major determinants for uniform seedling growth. The trait is complex and controlled by quantitative trait loci (QTLs). In this study, a linkage map consisting of 129 SSR markers was constructed, spanning 2,051.1 cM with ranging from 4.3 to 36.5 cM between adjacent markers. QTLs analysis at the(More)
Rice is the principal food for over half of the population of the world. With its genome size of 430 megabase pairs (Mb), the cultivated rice species Oryza sativa is a model plant for genome research. Here we report the sequence analysis of chromosome 4 of O. sativa, one of the first two rice chromosomes to be sequenced completely. The finished sequence(More)
Ginsenoside Rb1 has been demonstrated with neuroprotective effects, but the mechanisms remain unclear. This study aimed to probe the effects and mechanisms of ginsenoside Rb1 on activation of autophagy in glutamate-injured neurons. Ginsenoside Rb1 of exponential concentrations (1.2, 12, 120 microM) or autophagy inhibitor 3-methyladenine (5mM) was added to(More)
Personality traits have been shown to interact with environmental cues to modulate biological responses including treatment responses, and potentially having a role in the formation of placebo effects. Here, we assessed psychological traits in 50 healthy controls as to their capacity to predict placebo analgesic effects, placebo-induced activation of(More)
