Project description:The angle of rice leaf inclination is an important agronomic trait and closely related to the yield and architecture of crops. Through genetic screening, a rice gain-of-function mutant leaf inclination1, lc1, was identified . Phenotypic analysis confirmed the exaggerated leaf angels of lc1 due to the stimulated cell elongation at the collar.In this series, we compare the transcriptome of zhonghua11 and lc1 collar.

Project description:The leaf lamina joint joins the rice leaf blade and sheath, contributing significantly to the leaf angle trait. A more erect leaf facilitates the penetration of sunlight, enhancing photosynthetic efficiency and occupying less space in dense planting. Genetic screening found a mutant increased leaf angle1, ila1 from rice T-DNA insertional mutants library. We used microarrays to detail the transcriptional profile changes in the mutant ila1 lamina joint.

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:affy_xoo_rice - affy_xoo_rice - 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 that is devoted to the injection of type 3 effectors 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. We are interested in the functional analysis of a subgroup of Xoo T3Es, that are specialized in host cell transcriptome remodelling. These effectors, therefore called TAL for Transcription Activator-Like proteins (also named AvrBs3/PthA-like), are often key virulence factors essential to Xoo pathogenicity such as the effector protein Talc of african Xoo strain BAI3. Our goal is to understand its function during disease development, by identifying rice host genes that are being directly up- or down-regulated by Talc. To that end, we aim at performing Affymetrix transcriptomic analysis, comparing leaf samples of a susceptible rice line inoculated with Xoo to leaves challenged with a Talc-deficient mutant and water-treated leaves. Highly induced genes are likely to be Talc primary targets and therefore potentially good susceptibility gene candidates.-The goal of the experiment is to identify the rice genes up- or down-regulated by the type III effector Talc from Xoo African strain BAI3, upon the inoculation of susceptible rice leaves 24 hours post-infection. To that end, the experimental design includes the inoculation of Nipponbare rice leaves with the virulent Xoo strain BAI3, that will be compared to Nipponbare rice leaves inoculated with a talc K.O. mutant strain and water.

Project description:Overexpression of OsMYB103L leads to leaf rolling in transgenic rice plants. To explore the possible molecular mechanism of OsMYB103L’s effects on rice leaf development, we examined the expression profiles of OsMYB103L overexpression transgenic rice plants and wild type leaf blades using Digital Gene Expression (DGE) profiling analysis.

Project description:Elevated CO2 (eCO2) has an influence on developing leaf growth of rice (Oryza sativa cv. Nipponbare), specifically lower growth stage than P4 (plastochron number), resulting in decrease in leaf size compared with that in ambient CO2 (aCO2). Since several micro RNAs are associated with the regulation of plant leaf development, in order to clarify which micro RNAs are involved in the decrease of leaf blade size at eCO2, we carried out high-throughput small RNA sequencing analysis and compared the amount of identified miRNAs in developing rice leaf blade grown between aCO2 and eCO2 condition.

Project description:Lesion mimic mutants in rice are widely known as spotted leaf (spl) mutants, of which several genotypes exhibit enhanced resistance to different races of Magnaporthe grisea. Besides naturally occurring spotted leaf mutants, tissue culture-induced reverse genetic repositories also act as sources of lesion mimic mutants in rice. We systematically evaluated a large collection of Tos17 mutant panel lines, developed and maintained at the National Institute of Agrobiological Sciences, Tsukuba, Japan, for their reaction to three different races of M. grisea and identified a lesion mimic mutant, NF4050-8, that showed lesions similar to naturally occurring spl5 mutant and enhanced resistance to all three blast races tested. Microarray analysis of ~44,000 rice genes in NF4050-8 with Nipponbare as control during the progressive lesion appearance stage revealed significant up-regulation of numerous defense/pathogenesis-related genes as well as several WRKY domain-containing genes and down-regulation of haem peroxidase gene. Subsequent real-time PCR analysis of WRKY45 and PR1b genes in NF4050-8 and spl5 suggested possible constitutive activation of a defense signaling pathway downstream of Salicylic Acid (SA) but independent of NH1 in these mutant lines of rice.
