Project description:The goal is to know which kinds of gene are affected in rice leaves by OsHAP2E over-expression Transgenic rice with OsHAP2E driven by CaMV35S promoter was produced by Agrobacterium. The resultant two over-expressed lines were used for rice 44K microarray with two colors.

Project description:affy_riz_2011_7 - affy_riz_2011_7 - The Bacterial Leaf Blight disease of rice is due to Xanthomonas oryzae pv. oryzae. As for many pathogenic bacteria, it relies on a type 3 secretion system (TTSS) that is devoted to the injection of type 3 effectors (T3Es) into the eukaryotic host cell. These proteins are meant to suppress host basal defense responses and/or mimic some host regulatory function promoting bacterial survey in the plant. During an incompatible interaction, T3Es may act as Avr proteins and stimulate Effector-Triggered-Immunity. We aim at evaluating the transcriptomic response of rice leaves challenged with avirulent strains of Xoo BAI3 and MAI1 on resistant lines IR64 and IRBB4 versus the reference susceptible rice line Nipponbare. In addition, we investigated the transcriptomic response of rice leaves upon inoculation of an XoohrcC mutant strain affected in the production of a functional TTSS.-The goal of the experiment is to characterize the rice leaf transcriptome response, upon the inoculation of susceptible and resistant rice leaves 24 hours post-infection. To that end, the experimental design includes the inoculation of susceptible Nipponbare rice leaves with Xoo strains BAI3 (race A1) and MAI1 (race A3), that will be compared to the response of resistant lines IRBB4 and IR64 rice lines. In addition, Nipponbare rice leaves will also be challenged with the BAI3hrcC mutant that is affected in the production of a functional TTSS.

Project description:Several metals are essential nutrients for plants but metals are toxic in excess, deleteriously affecting crop yield and quality. Various kinds of genes involved in metal homeostasis have been investigated in detail over the past few decades and the mechanisms of how metals are absorbed from soil and distributed in plants have been elucidated. However, numerous genes related to metal homeostasis remain to be investigated and a comprehensive analysis of the expressions of these genes is required. In the present study, we investigated the spatial gene expression profile of iron (Fe)-deficient and cadmium (Cd)-stressed rice by a combination of laser capture microdissection and microarray analysis. We performed comprehensive microarray analysis of a rice root using laser microdissection and collected a total of 13 samples (3 replicates for each sample, 39 total microarray data). Roots of normal, Fe-deficient (-Fe) and Cd-stressed (+Cd) rice were separated into the vascular bundle (VB), cortex (Cor), and epidermis plus exodermis (EP). In addition, vascular bundles from new leaves (newDC) and old leaves (oldDC) at the lowest node, which are important for metal distribution, were separately analyzed.

Project description:Oryza sativa cv. Nipponbare was engineered to over-express a barley alanine aminotransferase (alaAT) gene using the promoter (OsANT1) from a rice aldehyde dehydrogenase gene that expresses in roots. We are using biotechnology to improve the nitrogen use efficiency of rice by over-expressing alaAT in a tissue specific (root) manner. The AlaAT enzyme is a reversible aminotransferase that is linked to both C and N metabolism since it uses pyruvate plus glutamate to produce alanine and 2-oxoglutarate, and visa versa.

Project description:Straw return is crucial for the sustainable development of rice planting. To investigate the response of rice leaves to rice straw return, we analyzed the physiological index of rice leaves and measured differentially expressed protein (DEPs) and differentially expressed metabolites (DEMs) levels in rice leaves by the use of proteomics and metabolomics approaches. The results showed that, compared with no rice straw return, rice straw return significantly decreased the dry weight of rice plants and nonstructural carbohydrate contents and destroyed the chloroplast ultrastructure. In rice leaves under rice straw return, 329 DEPs were upregulated, 303 DEPs were downregulated, 44 DEMs were upregulated, and 71 DEMs were downregulated. These DEPs and DEMs were mainly involved in various molecular processes, including photosynthesis, carbon fixation in photosynthetic organisms, glycolysis, and the citric acid cycle. Rice straw return promoted the accumulation of osmotic adjustment substances, such as organic acids, amino acids, and other substances, and reduced the material supply and energy production of carbon metabolism, thus inhibiting the growth of rice.

Project description:Treatment of rice roots with glutamate (Glu) induces systemic disease resistance against rice blast in leaves. To analyze the effect of Glu on the transcriptome of rice, rice roots were treated with Glu solution, and then fourth leaves were harvested and analyzed by Agilent rice microarray.
