Project description:The lem mutant was discovered in a doubled haploid (DH) line derived from the F1 of Gui-630 (Indica)xTaiwanjing (Japonica) by anther culture. The lem mutant did not affect other traits but caused all other floral organs (including palea, lodicule, stamen and carpel) to homeotically transform into lemma or lemma-like structures and caused floral meristem to be indeterminate, thus resulting in the mutant floret consisting of whorls of lemma and lemma-like organs. To identify the global gene expression changes mediated by LEM, we used 57K Affymetrix rice whole genome array to investigate the differences of genome-wide transcriptome between the young panicles of mutant lem versus WT samples during flower development stage. Keywords: rice (Oryza sativa L.),wild-type and lemmata mutant We generate gene expression profiles of rice cultivar Gui-630 (indica)x Taiwanjing (japonica) and mutant lemmata by using 57K Affymetrix rice whole genome array.

Project description:Expression Data of Rice Crown and Growing Point Tissue Under Salt Stress imposed during the Panicle Initiation Stage Experiment Overall Design: Rice Genotypes a sensitive japonica, m103, tolerant japonica agami, sensitive indica ir29 and tolerant indica ir63731 were used for expression anlaysis using the tissue from crown and growing point under control and salt stressed conditions at the sensitive early reproductive stage (panicel initiation).

Project description:Towards understanding gene expression variation among related rice lineages on a genome-wide scale, we sought to assess global gene expression in the heading-stage panicle using a whole genome oligonucleotide microarray designed to represent 36,926 annotated indica genes. Using a loop-design, we interrogated gene expression patterns in six related rice lineages, including O. sativa (two Asian cultivars indica and japonica), O. nivara (Asian annual wild rice), O. rufipogon (Asian perennial wild rice) and O. glaberrima (African cultivated rice).

Project description:The publicly available genome sequence information of two rice strains, japonica cultivar Nipponbare and indica cultivar 93-11, opens a great opportunity for investigation of performances DNA genotyping by high-density oligonucleotide arrays. Here, we compare single feature polymorphism (SFP) detection performances between whole genome hybridization and transcript hybridization using Affymetrix Rice Expression Array and the two rice cultivars.

Project description:Agrobacterium tumefaciens-mediated genetic transformation has been routinely used in rice for more than a decade. However, the transformation efficiency of the indica rice variety is still unsatisfactory and much lower than that of japonica cultivars. Further improvement on the transformation efficiency lies in the genetic manipulation of the plant itself, which requires a better understanding of the underlying process accounting for the susceptibility of plant cells to Agrobacterium infection as well as the identification of plant genes involved in the transformation process. In order to investigate the related genes affecting the transformation efficiency of embryogenic calli of different rice cultivars, we used Affymetrix GeneChip® Rice Genome Array to measure the global gene expression profiling just before transformation and at four different time points after transformation (1 h, 6 h, 12 h, 24 h) in both japonica rice cultivar Nipponbare and indica rice cultivar Zhenshan 97.

Project description:Rice is highly sensitive to drought, and the effect of drought may vary with the different genotypes and development stages. Genome-wide gene expression profiling was used as the initial point to dissect molecular genetic mechanism of this complex trait and provide valuable information for the improvement of drought tolerance in rice. Affymetrix rice genome array containing 48,564 japonica and 1,260 indica sequences was used to analyze the gene expression pattern of rice exposed to drought stress. The transcriptome from leaf, root, and young panicle at three developmental stages was comparatively analyzed combined with bioinformatics exploring drought stress related cis-elements. In this study, the gene expression patterns across six tissues including leaves and roots at tillering stage and panicle elongation stage, leaves and young panicle at booting stage ( TL: leaves at tillering stage; TR: roots at tillering stage; PL: leaves at panicle elongation stage; PR: roots at panicle elongation stage; BP: young panicle at booting stage; BL: leaves at booting stage) were characterized by using the Affymetrix rice microarray platform based on a drought tolerant rice line derived from IR64.
