Project description:By performing QTL mapping using 82 backcross inbred lines (BILs) of the Koshihikari (japonica) and Habataki (indica) cultivars for the rice initial growth, we identified two QTLs, qEPD1 and qEPD2, responsible for modulating plant height and/or leaf sheath length. To narrow down the number of candidate genes of each QTL, we conducted transcriptional profiling using RNAs isolated from the vegetative stem of Koshihikari and its two substituted lines (SL) with the Habataki qEPD1 or qEPD2 allele.

Expression profiling with the rice 44K-Agilent microarray (Agilent-028517) was conducted using RNAs extracted from the 30-day-old vegetative stem of the corresponding lines. Each dataset was obtained from three biological replicates.

Project description:In this study, we sequenced small RNA content from three different rice cultivars employing Illumina technology. More than 15 million reads were generated using Illumina high-throughput sequencing platform. After pre-processing, distinct small RNA sequences were identified for each rice cultivars. We collected seedlings of different rice cultivars and total RNA isolated was subjected to Illumina sequencing. The sequenced data was further filtered using NGS QC Toolkit to obtain high-quality reads. The filtered reads were pre-processed using modified perl script provided in the miRTools software. After quality control, the identical reads were collapsed into a unique read and read count for each sequence was recorded. All the filtered unique reads from each sample were mapped on the rice genome to find their location.

Project description:High ozone (O3) concentration causes serious damages in plant productivity. Climate models forecast that ground O3 level in the future will reach phytotoxic range, resulting in crop yield losses. With an ultimate goal to screen molecular factors to minimize losses of crop production by the rise of O3 level, we have started an investigation on effects of O3 on rice using rice DNA chip. Herein, we have utilized the samples of dry mature rice seeds harvested in an ozone-sensitive rice cultivar (Oryza sativa L. indica cv. Takanari) and a tolerant cultivar (Oryza sativa L. japonica cv. Koshihikari) which were fumigated with ambient air (mean O3: 32.7 ppb) in small open-top chambers (OTCs). First, we extracted total RNA from dry mature rice seeds of Takanari and Koshihikari using a modified protocol based on cethyltrimethylammonium bromide extraction buffer and phenol-chloroform-isoamylalcohol treatment. Furthermore, to perform microarray analysis using the Agilent 4x44 rice DNA Chip and the dye-swap method, we designed a balanced block design comparing seeds in an ambient air-fumigated rice cultivar and those in a filtered air-fumigated rice cultivar. Direct comparison of Koshihikari and Takanari O3 transcriptomes in seeds of rice plants fumigated with ambient O3 in OTCs successfully showed that genes encoding proteins involved in jasmonic acid, GABA biosynthesis, cell wall and membrane modification, starch mobilization, and secondary metabolite biosynthesis are differently regulated in an O3-sensitive cv. Takanari and a tolerant cv. Koshihikari.

Controls were plants grown under filtered air. Three biological replicates (4 plants in each biological replicate in each small open top chamber - seed; pooled) were used, and dye-swaped.
