Global expression analysis of differential expression of genes working under Soil Water Stress condition in different genotypes of rice in Vegetative and Grain-filling stage [set 1]

ABSTRACT: One of the serious constraints to realize high level of rice crop productivity in Indian agriculture has been due to soil moisture stress (SMS) situation that growing plants often face. In order to increase or maintain the crop productivity in SMS situation our initial aim is to understand the drought response mechanism in different genotypes of rice. For thorough analysis of SMS situation in rice we have taken here two wild genotypes of rice namely Oryza nivara, Oryza rufipogan and three Indian cultivar namely Oryza Nagina-22, Oryza IR20 and Oryza Vandana, where IR20 is known to be susceptible and Vandana is known to be tolerant under SMS condition. Global analysis of transcript profiling under SMS condition reveal the actual picture of genes responsive to stress situation in different genetic background of rice. Furthermore it would help us in the selection of most desirable resource for crop breeding without compromising the yield of crop. We used the 44k rice Oligoarray from Agilent technologies to study the transcript profiling from five genotypes of rice under control, soil moisture stress and after recovery conditions during vegetative and grainfilling phase.Here in case of Nagina-22 we have taken grainfilling stage.

Global expression analysis of differential expression of genes working under Soil Water Stress condition in different genotypes of rice in Vegetative and Grain-filling stage [set 2]

Project description:One of the serious constraints to realize high level of rice crop productivity in agriculture has been due to Soil Water Stress (SWS) situation that growing plants often face. In order to increase or maintain the crop productivity in SWS situation, our initial aim is to understand the drought response mechanism in different genotypes of rice. For thorough analysis of SWS situation in rice we have taken here two wild genotypes of rice namely Oryza nivara, Oryza rufipogon and three Oryza sativa indica cultivars namely Nagina-22, IR20 and Vandana, where IR20 is known to be susceptible and Vandana is known to be tolerant under SWS condition [GSE49364 and the current study]. Global analysis of transcript profiling under SWS condition reveal the actual picture of genes responsive to stress situation in different genetic background of rice. Furthermore it would help us in the selection of most desirable resource for crop breeding without compromising the yield of crop. We used the 44k rice Oligoarray from Agilent technologies to study the expression profiles from five rice genotypes during vegetative (Veg) and grain-filling (GF) stages under varying water conditions, viz. Before Stress (BS), After Stress (AS) and After Recovery (AR).

miR2118-triggered phased siRNAs are differentially expressed during the panicle development of wild and domesticated African rice species

Project description:Rice was domesticated independently in Asia and Africa, leading to two distinct but closely related crop species, Oryza sativa and Oryza glaberrima, respectively. The two domestications lead to morphological changes, in which a higher branching complexity of the panicles, influencing seed production and crop yield. Although much emphasis was placed on changes in transcriptional regulation during rice domestication and improvement, no large-scale study of small RNA regulation changes during domestication has been reported so far. To analyze whether rice domestication has altered the expression of small RNAs, we performed deep sequencing of small RNA transcriptomes from early developmental stages of panicles from 10 genotypes of the cultivated African species and 10 genotypes of its wild-relative O. barthii. Our study shows a drastic expression change of the 21-nucleotide smallRNA population. A total of 29% of these smallRNAs are overexpressed in panicles of O. barthii vs. O. glaberrima, corresponding mainly to 21-nucleotide phased siRNAs (or phasiRNAs). We also show that these changes are associated with a differential expression of a known regulator of phased siRNAs, miR2118 during early panicle development. Finally, these changes are associated to a heterochronic alteration of phasiRNAs and miR2118 expression pattern, during panicle development with a delayed expression in the domesticated species. Our study suggests a major reshaping of the regulation network from a specific class of small RNA during African rice domestication.

Transcriptome dynamics of rice spikelets under heat stress treatment

Project description:Rice reproductive development is highly sensitive to high temperature stress. In rice flowering occurs over a period of at least 5 days. Heat stress alters the global gene expression dynamics in panicle especially during pollen development, anthesis and grain filling. Some of the rice genotypes like Nagina 22 show better spikelet fertility and grain filling compared to high yielding and popular rice cultivars like IR 64. We carried out microarray analysis of 8 days heat stressed panicles of Nagina22, heat and drought tolerant aus rice cultivar and IR64, a heat susceptible indica genotype along with unstressed samples of Nagina22 and IR64 so as to understand the transcriptome dynamics in these two genotypes under heat stress and to identify the genes important for governing heat stress tolerance in rice.

Transcript profiling of drought responsiveness in two contrasting rice genotypes during vegetative stage stress

Project description:Rice (Oryza sativa), the major staple food crop is being cultivated under varying ecosystems ranging from irrigated lowland to rainfed upland environments. Improvement in the rice production under drought prone unfavourable environment depends on the development of drought tolerant genotypes which needs thorough understanding of physiological and molecular events behind the tolerance mechanism. There is considerable genetic variation for drought tolerance mechanism within the cultivated gene pool. To understand the diversity of drought response, two indica rice genotypes namely, i) Apo, an up-land drought tolerant indica veriety from Philippines and ii) IR64, a popular high yielding drought susceptible genotype were selected for this study. We used the 22K rice Oligoarray from Agilent technologies to study the transcript profile in the leaves of the two contrasting rice genotypes under control and drought stressed conditions during vegetative phase. Keywords: Drought response We used Agilent rice gene chips (G4138A) to investigate the transcript level changes in rice leaf tissues during drought stress. We used two contrasting rice genotypes (IR64 drought susceptible and Apo drought tolerant) differing in their degree of drought tolerance. Plants were grown under green house conditions and drought stress was imposed on 33rd DAS. Leaf sampling was done in both control and drought stressed plants after 6 days of drought stress. Three replications of microarray experiments were carried out by hybridizing the control samples against the drought stressed samples.

Transcriptome profile for leaves of rice plants subjected to severe reproductive stage drought stress

Project description:To understand how the qDTY12.1 interacts with other genes within the genome to give better physiological adaptations and better yield; the leaves transcriptome of DTY12.1 parents (Vandana , Way Rarem) and DTY12.1 NIL (481-B) were compared under control and drought conditions. Drought induced gene expression was studied in the leaves of the rice plants subjected to severe reproductive stage drought. Seeds of Vandana, Way Rarem, and 481-B were sown into rotovated soil at a rate of 2.0 g m-1 into plots of 3 rows X 3 m. The three genotypes were sown in three replications in a randomized complete block design.

Expression data from Oryza sativa and Arabidopsis thaliana

Project description:In this study, we used a cross-species network approach to uncover nitrogen (N)-regulated network modules conserved across a model and a crop species. By translating gene network knowledge from the data-rich model Arabidopsis (Arabidopsis thaliana, ecotype Columbia-0) to a crop, rice (Oryza sativa spp. japonica (Nipponbare)), we identified evolutionarily conserved N-regulatory modules as targets for translational studies to improve N use efficiency in transgenic plants.
