Recent retrotransposon insertions are methylated and phylogenetically clustered in japonica rice (Oryza sativa spp. japonica).
In plants, the genome of the host responds to the amplification of transposable elements (TEs) with DNA methylation. However, neither the factors involved in TE methylation nor the dynamics of the host-TE interaction are well resolved. Here, we identify 5,522 long terminal repeat retrotransposons (LTR-RT) in the genome of Oryza sativa ssp. japonica and then assess methylation for individual ele...
متن کاملRetrogenes in Rice (Oryza sativa L. ssp. japonica) Exhibit Correlated Expression with Their Source Genes
Gene duplication occurs by either DNA- or RNA-based processes; the latter duplicates single genes via retroposition of messenger RNA. The expression of a retroposed gene copy (retrocopy) is expected to be uncorrelated with its source gene because upstream promoter regions are usually not part of the retroposition process. In contrast, DNA-based duplication often encompasses both the coding and ...
متن کاملInfluence of cooking on anthocyanins in black rice (Oryza sativa L. japonica var. SBR).
The composition and thermal stability of anthocyanins in black rice (Oryza sativa L. japonica var. SBR) produced in California were investigated. Six anthocyanin pigments were identified and quantified by high performance liquid chromatography using photo diode-array detection (HPLC-PDA) and electrospray ionization mass spectrometry [LC-(ESI)MS/MS]. The predominant anthocyanins are cyanidin-3-g...
متن کاملTranscriptome-based examination of putative pollen allergens of rice (Oryza sativa ssp. japonica).
Pollen allergens are among the most abundantly transcribed and translated products in the life history of plants, and particularly grasses. To identify different pollen allergens in rice, putative allergens were identified in the rice genome and their expression characterized using the Affymetrix 57K rice GeneChip microarray. Among the most abundant pollen-specific candidate transcripts were Or...
متن کاملThe Rice Annotation Project Database (RAP-DB): hub for Oryza sativa ssp. japonica genome information
With the completion of the rice genome sequencing, a standardized annotation is necessary so that the information from the genome sequence can be fully utilized in understanding the biology of rice and other cereal crops. An annotation jamboree was held in Japan with the aim of annotating and manually curating all the genes in the rice genome. Here we present the Rice Annotation Project Databas...
