Transcriptome and methylome interactions in rice hybrids

ABSTRACT: This research reports genome-wide measurements of genetic and epigenetic patterns of inheritance through an integrative analysis of BS-seq, RNA-seq, and siRNA-seq data in two inbred parents of the Nipponbare (NPB) and Indica (93-11) variety of rice and their hybrid offspring. We generated integrative maps of whole genome cytosine methylation profiles (BS-Seq), transcriptional profiles (RNA-seq), and small RNA profiles (sRNA-seq) to characterize two rice subspecies, Oryza sativa spp japonica (Nipponbare) and Oryza sativa spp indica (93-11) and their two reciprocal hybrid offspring using Illumina's sequencing-by-synthesis (SBS) platform .

DNA methylation is a heritable epigenetic mark that controls gene expression, is responsive to environmental stresses, and, in plants, may also play a role in heterosis. To determine the degree to which DNA methylation is inherited in rice, and how it both influences and is affected by transcription, we performed genome-wide measurements of these patterns through an integrative analysis of bisulfite-sequencing, RNA-sequencing, and siRNA-sequencing data in two inbred parents of the Nipponbare (NP ...[more]

Transcription profiling by array of rice plants grown in different light and temperature conditions

Project description:Rice (Oryza sativa, spp. Indica, cv. 93-11) plants were grown in a Conviron PGR 15 growth chamber using precise control of temperature, light, and humidity.<br>Diurnal (driven) conditions included 12L:12D light cycles and 31C/20C thermocycles in three different combinations. These were: photocycles (LDHH), 12 hrs. light (L)/12 hrs. dark (D) at a constant temperature (31C; HH); photo/thermocycles (LDHC): 12 hrs. light (L) /12 hrs. dark (D) with a high day temperature (31C) and a low night temperature (20C); and thermocycles (LLHC): continuous light (LL) with 12 hrs. high/12 hrs. low temperature (31C, day; 20C, night). Light intensity and relative humidity were 1000 micromol m-2s-2 and 60%, respectively.<br>Three-month-old rice plants were entrained for at least one week under the respective condition prior to initiation of each experiment. Leaves and stems from individual rice plants were collected every four hours for 48 hrs in driven (diurnal) conditions followed by a two day freerun spacer under continuous light/temperature followed by two additional days of sampling under the same continuous free run condition.

RNase ZS1-mediated UbL40 mRNA decay controls thermo-sensitive genic male sterility in rice.

Project description:Male sterility is an important trait in hybrid crop breeding. Thermo-sensitive genic male sterility (TGMS) lines, which are male-sterile at restrictive (high) temperatures but convert to male-fertile at permissive (low) temperatures, have been widely utilized in two-line hybrid rice breeding3. However, the molecular mechanism underlying TGMS remains unclear. Here we show that the rice (Oryza sativa L.) thermo-sensitive genic male sterile gene 5 (tms5) locus, which in 2010 was present in cultivars occupying more than 70% (2.4 million hectares) of two-line hybrid rice-growing land in China, confers the TGMS trait through a loss-of-function mutation of RNase ZS1, resulting in failure to mediate mRNA decay of three temperature-responsive ubiquitin fusion ribosomal protein L40 genes (UbL40). TMS5 encodes an evolutionarily conserved endonuclease, RNase ZS1. RNase ZS1 can process tRNAs in vitro, but does not do so in vivo due to its localization in the cytoplasm. Defective RNase ZS1 in tms5 plants leads to over-accumulation of UbL401, UbL402 and UbL404 mRNAs at restrictive but not permissive temperatures. Furthermore, over-expression of UbL401 and UbL404 in wild-type plants causes male sterility, while knockdown of UbL401 and UbL404 in tms5 partially restores its fertility. Our results uncover a novel mechanism of RNase ZS1-mediated UbL40 mRNA decay which controls TGMS in rice and has potential applications in hybrid breeding not only of rice but also of other crops. Examination of differences in mRNA accumulation between 93-11, NIL5 and NIL8.

Genome-wide maps of DNA methylation state in rice embryo and endosperm

Project description:We report the application of methylacytosine immunoprecipetation combined with Illumina sequencing (MeDIP-seq) for high-throughput profiling of DNA methylation in rice embryo 3, 6, 9 DAP and endosperm 2, 3, 6, 9 DAP. A total number of 12-14 million of 2×49 bp paired-end reads was generated for each sample, and BOWTIE2 was used for read mapping. We generated genome-wide DNA methylation profiles of rice embryo and endosperm. This study provides a framework to systemically characterize the effect of DNA methylation in developing seeds and will help to illustrate the epigenetic regulation of rice seed development. Rice embryo and endosperm were selected for DNA extraction and methylacytosine immunoprecipetation combined with Illumina sequencing. We sought to obtain the genome-wide DNA methylation profilings of embryo at 3,6,9 days after pollination(DAP) and endosperm at 2,3,6,9 DAP. To that end, we hand-selected embryo at 3,6,9 DAP and endosperm at 2,3,6,9 DAP according to morphological criteria.

Calcium deficient transcriptome analysis of rice

Project description:Calcium is an essential macronutrient and plant requires it in large amounts for normal growth and development. This ion participated in innumerable processes and affects nearly all aspects of plant growth and development such as signal transduction, metabolism of lipids, proteins, and carbohydrates, cell growth, cell wall and membrane stabilization. We used whole genome microarrays to determine the transcriptomic profile of rice seedlings exposed to short-term and long term Ca2+ deficiency followed by Ca2+ resupply. Calcium treated seedlings were used for for RNA extraction and hybridization on Agilent microarray platform. Three biological replicates of each sample were used for microarray analysis. We wanted to know the altered expression patterns of calcium-responsive genes majorly involved in metabolic processes, signal transdction pathways, transcriptional regulation, and transport of multiple molecules including Ca2+. Seeds of indica rice were surface sterilized and grown hydroponically in rice growing medium. Plants were grown in the rice growth room under the condition of 16 h light/8 h dark (28M-BM-0C) photoperiod with 70 % humidity. After 5 days of normal growth, some of the seedlings were transferred to nutrient solution lacking CaCl2 (-Ca2+). After 5 and 14 days, calcium (0.798 mM CaCl2) was resupplied to the plants grown in -Ca2+ medium for 6 h.

Degradome sequencing reveals endogenous small RNA targets in rice (Oryza sativa L. ssp. indica)

Project description:MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) regulate gene expression in eukaryotes. Plant miRNAs modulate their targets mainly via messenger RNA (mRNA) cleavage. Small RNA targets have been extensively investigated in Arabidopsis using computational prediction, experimental validation, and degradome sequencing. However, small RNA targets are largely unknown in rice (Oryza sativa). Here, we report global identification of small RNA targets using high throughput degradome sequencing in the rice indica cultivar 93-11 (Oryza sativa L. ssp. indica). 177 transcripts targeted by total of 87 unique miRNAs were identified. Of targets for the conserved miRNAs between Arabidopsis and rice, transcription factors comprise around 70% (58 in 82), indicating that these miRNAs act as masters of gene regulatory nodes in rice. In contrast, non-conserved miRNAs targeted diverse genes which provide more complex regulatory networks. In addition, 5 AUXIN RESPONSE FACTORS (ARF) cleaved by the TAS3 derived ta-siRNAs were also detected. A total of 40 sRNA targets were further validated via RNA ligase-mediated 5M-bM-^@M-^Y rapid amplification of cDNA ends (RLM 5M-bM-^@M-^Y-RACE). Our degradome results present a detailed sRNA-target interaction atlas, which provides a guide for the study of the roles of sRNAs and their targets in rice. The degradome sequence of Young inflorescences from Oryza sativa L. ssp. indica (93-11) was sequenced

Rice gene expression using Agilent custom 8X60K Microarray

Project description:We designed an array based on the release 7 of Michigan State University (MSU) rice genome annotation database (http://rice.plantbiology.msu.edu). The array was used for investigating the expression divergence and regulation between two contrasting rice genotypes under high salinity stress. The expression analysis was carried out using 14-day old whole seedlings from both japonica and indica rice lines. Two samples from NaCl treatment (0h and 8h) for each line were collected for the analysis. Two biological replicates were carried out for both control and NaCl treatments, resulting in a dataset of 8 microarrays.

Gene expression analysis of rice seedling under potassium deprivation

Project description:Potassium is one of the essential macronutrients required for plant growth and development. It plays a major role in different physiological processes like cell elongation, stomatal movement, turgor regulation, osmotic adjustment, and signal transduction by acting as a major osmolyte and component of the ionic environment in the cytosol and subcellular organelles. We used whole genome microarrays to determine the transcriptomic profile of rice seedlings exposed to short-term K+ deficiency followed by K+ resupply. Potassium treated seedlings were used for RNA extraction and hybridization on Affymetrix rice Genechip by microarrays. Three biological replicates of each sample were used for microarray analysis. We wanted to know the altered expression patterns of potassium-responsive genes majorly involved in metabolic processes, stress responses, signaling pathways, transcriptional regulation, and transport of multiple molecules including K+. Seeds of indica rice were surface sterilized and grown hydroponically in rice growing medium. Plants were grown in the rice growth room under the condition of 16 h light/8 h dark (28°C) photoperiod with 70 % humidity. After 5 days of normal growth, one half of the rice seedlings were transferred to nutrient media with normal concentration of potassium (KP, 0.409 mM K2SO4) and other one half to medium without potassium (KM, 0 mM). After 5 days, potassium (0.409 mM K2SO4) was resupplied to the plants grown in KM medium for 6 h.

Transcriptomic profiling of rice (Oryza sativa) cv. Sijung and Jumli Marshi during early chilling stress

Project description:The aim of this study was to conduct global gene expression profiling and comparative analysis of two chilling tolerant rice varieties, Jumli Marshi and Sijung (spp. Japonica), during early chilling stress (24h, 10C). Leaf tissue from cv. Jumli Marshi and cv. Sijung plants grown under chilling stress conditions were harvested after 4 and 24 h. Control plants (0 h) were harvested at the beginning of the experiment, i.e., at mid-day. Three biological replicates were profiled for each time point and variety. In order to readily detect highly (saturated) as well as weakly (near background signal) expressed genes, scanning was done twice on the microarrays: at the PMT sensitivity level 100% (pmt100) and 10% (pmt10).
