We produced 102 randomly amplified polymorphic DNA (RAPD) markers mapped on all 12 chromosomes of rice using DNAs of cultivars Nipponbare (japonica) and Kasalath (indica) and of F2 population generated by a single cross of these parents. Sixty random primers 10 nucleotides long were used both singly and in random pairs and about 1,400 primer-pairs were tested. Using both agarose gel and polyacr...
Salt stress is an important abiotic stress, which has seriously affected the reproductive development of rice in many parts world. Therefore, it particularly to understand genetic mechanism salt tolerance rice. In this study, we preliminarily located some quantitative trait loci (QTL) for root length, bud and survival percent under different salinity conditions (0, 100, 200 400 mM NaCl), using ...
When performing a genome-wide comparison between indica (93-11) and japonica (Nipponbare), we find 8% of the genome, which have an extremely low SNP rate (< 1 SNP/kb). Inside these 'SNP deserts', experimentally confirmed genes show increased K(a)/K(s) that indicate adaptive selection. To further elucidate this connection, we survey the level and pattern of genetic variation in both cultivated a...
1000-Grain weight and spikelet number per panicle are two important components for rice grain yield. In our previous study, eight quantitative trait loci (QTLs) conferring spikelet number per panicle and 1000-grain weight were mapped through sequencing-based genotyping of 150 rice recombinant inbred lines (RILs). In this study, we validated the effects of four QTLs from Nipponbare using chromos...
We have identified about 20 million rice SNPs by aligning reads from the 3000 rice genomes project with the Nipponbare genome. The SNPs and allele information are organized into a SNP-Seek system (http://www.oryzasnp.org/iric-portal/), which consists of Oracle database having a total number of rows with SNP genotypes close to 60 billion (20 M SNPs × 3 K rice lines) and web interface for conveni...
Many quantitative trait loci (QTLs) for agronomically important traits such as grain yield, disease resistance, and stress tolerance of rice (Oryza sativa L.) have been detected by using segregating populations derived from crosses between indica and japonica subspecies or with wild relatives. However, the QTLs involved in the control of natural variation in agronomic traits among closely relat...
Monogalactosyldiacylglycerol (MGDG) is the most abundant lipid on earth and constitutes about 50% of polar lipids in thylakoid membrane higher plants. MGDG synthase (MGD) key enzyme responsible for synthesis However, so far, function MGD gene plant stress responses still unknown, especially crop In this study, performances wild-type rice (Oryza sativa L. Nipponbare), OsMGD overexpression, RNA i...
