Integrative Comparative Proteomics Identifies Core Differentially Expressed Proteins and Pathways for Drought Tolerance by Exploiting Contrasting Rice Varieties

ABSTRACT: More tightly coordinated response was revealed at the protein level in the tolerant varieties by proteomic analysis. Carbohydrate metabolism, redox homeostasis and protein transport were found activated in the tolerant varieties in functional enrichment analysis; while photosynthesis was suppressed. However, the networks of protein-protein interaction between more drought tolerant lines were richer and well connected. In the interaction networks of proteins, these two drought tolerant lines had key hub proteins which play pivotal roles in effective signal transduction. The results systematically presented the complex regulatory network basis of drought resistance in rice, and offered novel molecular targets for screening drought tolerance in rice.

RNA-seq analyses of most resistance Indica Rice varieties (Oryza sativa L.) leaves tissue under water-deficit condition

Project description:In order to evaluate the genome differences and find the more tolerant cultivar, first eleven Malaysian rice cultivars namely, MR219, MR276, MR220, MR211, MR219-4, MR253, Q50, Q74, MR159, Masuri and MR263 were subjected under water deficit. Then, based on the morphological and physiological traits, the more drought-tolerant and -susceptible cultivars were screened and time-course gene expression profiling established by a comprehensive transcriptome database sequencing of the leaf RNA of tolerant rice. The current investigation provides pivotal data for understanding the rice drought tolerance mechanisms.

Transcriptomic expression patterns of two contrasting lowland rice varieties reveal high iron stress tolerance

Project description:Iron (Fe) toxicity is a major challenge for plant cultivation in acidic water-logged soil environments, where lowland rice is a major staple food crop. Only few studies addressed the molecular characterization of excess Fe tolerance in rice, and these highlight different mechanisms for Fe tolerance in the studied varieties. Here, we screened 16 lowland rice varieties for excess Fe stress growth responses to identify contrasting lines, Fe-tolerant Lachit and -susceptible Hacha. Hacha and Lachit differed in their physiological and morphological responses to excess Fe, including leaf growth, leaf rolling, reactive oxygen species generation, Fe and metal contents. These responses were mirrored by differential gene expression patterns, obtained through RNA-sequencing, and corresponding GO term enrichment in tolerant versus susceptible lines. From the comparative transcriptomic profiles between Lachit and Hacha in response to excess Fe stress, individual genes of the category metal homeostasis, mainly root-expressed, may contribute to the tolerance of Lachit. 22 out of these 35 metal homeostasis genes are present in selection sweep genomic regions, in breeding signatures and/or differentiated during rice domestication. These findings will serve to design targeted Fe tolerance breeding of rice crops.

Expression data from rice varieties Azucena and Bala grown in 0 and 1ppm arsenate

Project description:We advance a three gene model of arsenate tolerance in rice based on testing root growth of 108 recombinant inbred lines (RILs) of the Bala x Azucena population. Marker genotype at 3 loci determined arsenate tolerance in 99% of RILs tested. Interestingly, plants must inherit 2, but any two alleles from the tolerant parent (Bala) to have the tolerant phenotype. Challenging the Affymetrix GeneChip Rice Genome array with Azucena and Bala RNA isolated from control and arsenate treated plants revealed 592 genes 2 fold-upregulated by arsenate and 696 downregulated. The array data was also used to identify which genes are expressed within the three target loci. We used microarrays to detail the gene expression at three locations in the rice genome termed AsTol6.1, AsTol6.2 and AsTol10 in response to 1ppm arsenate. The data was also used to study the global gene expression of the two varieties of rice, Azucena and Bala, in the presence of 1ppm arsenate.

Soil salinity and mechanical obstruction differentially affects embryonic root architecture in native rice varieties of West Bengal

Project description:Roots make the first contact with the soil environment and are the first responders of stress. These root behaviors are quantifiable and adaptive. The response of rice varieties in mechanical and salinity stress was measured in a novel experimental setup that mimics the soil environment. We analyzed the response of roots by means of SAC (Stress Adaptation Coefficient) in 28 rice varieties that include high-yield salt tolerant varieties as well as geographically isolated native rice varieties. cDNA microarray of IR64 root-tip shows about 6000 common transcripts to be differentially regulated among the two stresses and common pathways were identified. Overall, our study indicates that there is an important commonality in the molecular basis of salt and mechanical stress and presents an easy-to-perform early establishment stress screen for rice varieties.

System responses to long-term drought and re-watering of two contrasting alfalfa varieties

Project description:Two alfalfa varieties, 'Chilean' (M. sativa ssp. sativa var. Chilean, drought sensitive) and 'Wisfal' (M. sativa ssp. falcata var. Wisfal, drought tolerant), with contrasting water use efficiency were subjected to water withholding for 11 days followed by re-watering. Samples were taken for well-watered plants and plants after five, eight, eleven days of drought stress as well as plants after recovery for one day following drought stress. Roots and shoots were sampled and analyzed separately by expression profiling using Affymetrix Medicago GeneChip.

Transcription profiling of parental lines and bulked salt sensitive and salt tolerant RILs derived from 2 rice varieties

Project description:The aim of this study was to minimize the number of candidate genes responsible for salt tolerance between a pair of rice varieties (CSR27 and MI48) with contrasting level of salt tolerance by bulked segregant analysis of their recombinant inbred lines. Microarray analysis of RNA extracted from the tolerant and susceptible parents without and with stress showed 798 and 2407 differentially expressed genes, respectively. The number of differentially expressed genes was drastically reduced to 70 and 30, by pooling the RNAs from ten extreme tolerant and ten extreme susceptible RILs due to normalization of irrelevant differentially expressed genes between the parents.

Transcriptome profiling for drought tolerant and susceptible cultivars of indica rice

Project description:Traditional rice varieties found in India have many desirable characteristics. Amongst them, their differential responses to abiotic and biotic stresses are of great agricultural importance. Drought or osmotic stress is one of the major abiotic stresses afflicting crop plants in India. Indigenous varieties like Dagad deshi have been found to be drought resistant and, thereby, are being studied in great detail by plant breeders and biotechnologists alike. In this study, we have analyzed the transciptomes of two contrasting cultivars, i.e. Dagad deshi (tolerant) and IR20 (susceptible), under control and stress conditions to elucidate the differences in their responses to drought stress using Affymetrix microarray platform.
