Genomic Variation in Rice: Genesis of Highly Polymorphic Linkage Blocks during Domestication

Genomic regions that are unusually divergent between closely related species or racial groups can be particularly informative about the process of speciation or the operation of natural selection. The two sequenced genomes of cultivated Asian rice, Oryza sativa, reveal that at least 6% of the genomes are unusually divergent. Sequencing of ten unlinked loci from the highly divergent regions cons...

Genomic variation associated with local adaptation of weedy rice during de-domestication

De-domestication is a unique evolutionary process by which domesticated crops are converted into 'wild predecessor like' forms. Weedy rice (Oryza sativa f. spontanea) is an excellent model to dissect the molecular processes underlying de-domestication. Here, we analyse the genomes of 155 weedy and 76 locally cultivated rice accessions from four representative regions in China that were sequence...

SNP deserts of Asian cultivated rice: genomic regions under domestication.

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...

Genomic dissection of small RNAs in wild rice (Oryza rufipogon): lessons for rice domestication.

The lack of a MIRNA set and genome sequence of wild rice (Oryza rufipogon) has prevented us from determining the role of MIRNA genes in rice domestication. In this study, a genome, three small RNA populations and a degradome of O. rufipogon were sequenced by Illumina platform and the expression levels of microRNAs (miRNAs) were investigated by miRNA chips. A de novo O. rufipogon genome was asse...

Polymorphic Blocks

We present a novel block-based UI called Polymorphic Blocks, in which a connector’s shape visually represents the structure of the data being passed through the connector. We use Polymorphic Blocks to add visual type information to block-based programming environments like Blockly or Scratch. We also use Polymorphic Blocks to represent logical proofs. In this context, if we erase all symbols, o...
