Cool-responsive change in the rice anther transcriptome

ABSTRACT: The genome-wide transcriptome analyses using microarray probes containing genes and repeat sequences have been performed to examine response to the low-temperature in rice. We have particularly focused on the rice anther at the booting stage, since the low-temperature at this stage resulted in pollen abortion. The results demonstrated that the low-temperature stress caused genome-wide changes of transcriptional activities not only in genes, but also in repeat sequences of the rice anther. The degrees of the temperature responsive changes varied among the rice strains.

Cool-responsive change in the rice anther transcriptome

Project description:The genome-wide transcriptome analyses using microarray probes containing genes and repeat sequences have been performed to examine response to the low-temperature in rice. We have particularly focused on the rice anther at the booting stage, since the low-temperature at this stage resulted in pollen abortion. The results demonstrated that the low-temperature stress caused genome-wide changes of transcriptional activities not only in genes, but also in repeat sequences of the rice anther. The degrees of the temperature responsive changes varied among the rice strains. The five rice strains exposed to the low temperature at 12Â°C for four days, were used for the microarray analyses. RNA was extracted from the anthers one day (C1), three days (C3) and five days (C5: this is one day after completion of the cool treatment) after the cool treatment and non-treated anthers (C0) with three biological replicates.

The rice anther transcriptomes responded to low temperature

Project description:Transcriptome analysis using a microarray equipped with probes for genes and repetitive sequences has been performed to examine the expression change in rice anther. We performed transcriptome analysis in 13 rice lines with different cold tolerances at the booting stage because the low temperature at this stage resulted in pollen sterility. From our study, it was found that genome-wide expression is negatively correlated with the degree of cold tolerance.

The rice anther transcriptomes responded to low temperature [RNA-seq]

Project description:The booting stage of rice shows the most sensitivity to cold stress, and low-temperature stress causes irreversible pollen sterility. We performed transcriptome analysis using RNA-seq to investigate the response of rice anthers to low-temperature stress. In this RNA-seq analysis, to validate the results of transcriptome analysis of anthers from 13 rice lines using microarrays, four cultivars were selected for analysis from the 13 tested for microarrays.

Gene expression profiling of flower and leaf of Cold-tolerant rice variety Stejaree45

Project description:To stabilize crop yield under low temperature stress conditions, it is important to improve stress tolerance in crops. Upon exposure to low temperature stress, many genes are induced and their products are thought to function as cellular protectants of stress-induced damages Therefore, responses of global gene expression profiles to cold stress was analyzed at the booting stage using the 60K Rice Whole Genome Microarray. The cold-tolerant rice variety, Stejaree45 was transplanted in 1/5000 pot at 20 days after seeding. Fertilizers were applied at the rate of 11, 7.7 and 9.3 kg/10a in N, P2O5 The samples were selected at the booting stage of rice on the basis of the auricle distance (the distance between auricles of flag leaf and the previous leaf of the main culm). The plants with an auricle distance ranging from -5 ㎝ to 0 ㎝ were exposed up to the flag leaf auricle using cold water (13℃) for 3 days. Glumous flowers and flag leaves of the cold-resistant variety, Stejaree45, were used to examine gene expression profiles.

Genome-wide temporal-spatial gene expression profiling of drought responsiveness in rice

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.

Proteomic Changes of Wheat Male Sterile Anther Induced by Temperature

Project description:Wheat, an important human food crop, is very sensitive to temperature changes. Thermosensitive sterile lines (TMS) is a natural material for exploring the effects of anther development and temperature changes on male fertility. In order to study the possible molecular mechanism of regulating protein activity during anther fertility alteration, proteomics analysis based on high resolution mass spectrometry were used to study the binuclear anther of wheat YS3038.

miR167 limits anther growth to potentiate anther dehiscence

Project description:In flowering plants, anther dehiscence and pollen release are essential for sexual reproduction. Anthers dehisce after cell wall degradation weakens stomium cell junctions in each anther locule, and desiccation creates mechanical forces that open the locules. Either effect or both together may break stomium cell junctions. The microRNA miR167 negatively regulates ARF6 and ARF8, which encode Auxin Response transcription Factors. Arabidopsis mARF6 or mARF8 plants with mutated miR167 target sites have defective anther dehiscence and ovule development. Null mir167a mutations recapitulated mARF6 and mARF8 anther and ovule phenotypes, indicating that MIR167a is the main miR167 precursor gene that delimits ARF6 and ARF8 expression in these organs. Anthers of mir167a or mARF6/8 plants overexpressed genes encoding cell wall loosening functions associated with cell expansion, and grew too large starting at flower stage 11. Experimental desiccation enabled dehiscence of miR167-deficient anthers, indicating competence to dehisce. Conversely, high humidity conditions delayed anther dehiscence in wild-type flowers. These results support a model in which miR167-mediated anther growth arrest permits anther dehiscence. Without miR167 regulation, excess anther growth delays dehiscence by prolonging desiccation.
