Oryza sativa strain:Zhonghua11 Transcriptome or Gene expression

ABSTRACT: In the current study, we characterized an miRNA, OsmiR397, which was found to be associated with increased grain size, more rice panicle branching and higher grain productivity. We also elucidated the molecular mechanisms by which OsmiR397 increased grain yield. This miRNA downregulated the expression of its target gene, OsLAC, which then affected the sensitivity of plants to brassinosteroids. These results should be useful for breeding high-yield crops through genetic engineering. We performed RNA-seq on the young panicles of the wild-type, OXmiR397b and OXLAC plants and found that lots of brassinosteroid-related genes were differentially expressed between the three samples

Increasing grain yields is a major focus of crop breeders around the world. Here we report that overexpression of the rice microRNA (miRNA) OsmiR397, which is naturally highly expressed in young panicles and grains, enlarges grain size and promotes panicle branching, leading to an increase in overall grain yield of up to 25% in a field trial. To our knowledge, no previous report has shown a positive regulatory role of miRNA in the control of plant seed size and grain yield. We determined that Os ...[more]

Epigenetic variation through the breeding processes of maize

Project description:The concurrent epigenetic changes during this period of remarkable improvement in maize grain yield remain unknown. Here, we performed MethylC-seq and RNA-seq on 4 related inbred lines with known pedigree information. Analysis of epigenetic changes over the course of historical maize breeding is a valuable new avenue in the exploration for crop improvement. These data lead us to suggest that novel epihaplotypes, in addition to DNA variation, are a substrate of selection during breeding, and that epigenetic variation between parents may also contribute to heterosis in hybrids.

Oryza sativa Transcriptome or Gene expression

Project description:A biological phenomenon in which hybrids exhibit superior phenotypes from its parental inbred lines known as heterosis, has been widely exploited in plant breeding and extensively used in crop improvement. Hybrid rice has immense potential to increase yield over other rice varieties and hence is crucial in meeting increasing demand of rice globally. Moreover, the molecular basis of heterosis is still not fully understood and hence it becomes imperative to unravel its genetic and molecular basis. In this context, RNA sequencing technology (RNA-Seq) was employed to sequence transcriptomes of two rice hybrids, Ajay and Rajalaxmi, their parental lines, CRMS31A (sterile line, based on WA-CMS) and CRMS32A (sterile line based on Kalinga-CMS) respectively along with the common restorer line of both hybrids, IR-42266-29-3R at two critical rice developmental stages viz., panicle initiation (PI) and grain filling (GF). Identification of differentially expressed genes (DEGs) at PI and GF stages will further pave the way for understanding heterosis. In addition, such kind of study would help in better understanding of heterosis mechanism and genes up-regulated and down-regulated during the critical stages of rice development for higher yield.

Oryza sativa Transcriptome or Gene expression

Project description:We analyzed the transcriptome profiles for rice grain from heat-tolerant and -sensitive lines in response to high night temperatures at the early milky stage using the Illumina Sequencing method. On the 8th day after the labeled florets flowered, plants with the same label were transferred to chambers and maintained at a temperature of 38.0âÂ±â0.5Â°C (treatment) or 25.0âÂ±â0.5Â°C (control) for the dark period (10 h), and 26.0âÂ±â0.5Â°C (both treatment and control) for the light period (14 h). Three biological replicates of the temperature treatments were grown under the same conditions. After 48 h of treatment, samples containing 45 grains with labels from the same region (middle to bottom part) of labelled ears were harvested, packed in aluminum foil, and flash-frozen in liquid nitrogen until further use. A total of 12 rice grain samples were harvested, i.e., controls (TC1, TC2 and TC3) and treatments (TT1, TT2 and TT3) of the three biological replicates of the heat-tolerant line, and controls (SC1, SC2 and SC3) and treatments (ST1, ST2 and ST3) of the three biological replicates of the heat-sensitive line.

Whole transcriptome sequencing of wheat 3B chromosome

Project description:To study the expression profiles of hexaploid wheat chromosome 3B genes during the life cycle of a wheat plant and establish a transcriptome atlas for this chromosome, deep transcriptome sequencing was conducted in duplicates in 15 wheat samples corresponding to five different organs (leaf, shoot, root, spike, and grain) at three developmental stages each. Strand-non-specific and strand-specific libraries were used to produce 2.52 billion paired-end reads (232 Gb) and 615.3 single-end reads (62 Gb), respectively.

Glycine max Transcriptome or Gene expression

Project description:Tropospheric ozone (O3) is a secondary air pollutant and anthropogenic greenhouse gas. Concentrations of tropospheric O3 have more than doubled since the Industrial Revolution, and are high enough to damage plant productivity. Soybean (Glycine max L. Merr.) is the worldâs most important legume crop and is sensitive to O3. Current ground-level O3 are estimated to reduce global soybean yields by 6% to 16%. In order to understand transcriptional mechanisms of yield loss in soybean, we examined the transcriptome of soybean flower and pod tissues exposed to elevated O3 using RNA-Sequencing.

Triticum aestivum strain:cultivar Transcriptome or Gene expression

Project description:The pistillody mutant wheat (Triticum aestivum L.) plant HTS-1 exhibits homeotic transformation of stamens into pistils or pistil-like structures. Unlike common wheat varieties, HTS-1 produces three to six pistils per floret, potentially increasing the yield. Thus, HTS-1 is highly valuable in the study of floral development in wheat. In this study, we conducted RNA sequencing of the transcriptomes of the pistillody stamen (PS) and the pistil (P) from HTS-1 plants, and the stamen (S) from the non-pistillody control variety Chinese Spring TP to gain insights into pistil and stamen development in wheat.

Glycine max strain:93B15 Transcriptome or Gene expression

Project description:The seed coat is a vital tissue for directing nutrient supply to the embryo and cotyledons during development. By forming a sucrose gradient, the seed coat promotes transport of sugars from source leaves to seeds, thereby increasing sink strength. Understanding how gene regulation in sink tissue is altered by climate change factors will help elucidate the role these genes play in determining yield. This project aims to determine how elevated temperature, drought and ozone alter gene expression in the seed coat. Overall this study discovered high abundance seed coat specific genes, which may be candidates for functional genomic analysis in the future.

Comparing the response to chronic ozone of five agriculturally important legume species.

Project description:In the past 100 years, tropospheric ozone concentrations [O3] have more than doubled in response to industrialization. Current [O3] can cause oxidative damage in plants, leading to yield losses that have been estimated to cost growers $1.8-3.6 billion per year for soybean in the US. Models indicate that [O3] will continue to rise another 25% by the year 2050, thus exacerbating the strain on agriculture to provide food at a time of rapid population growth. To identify specific markers of O3 tolerance at the molecular level, we have undertaken a transcriptome sequencing approach using the Illumina platform. RNA-seq details: total RNA was isolated from the leaves of 3 control and 3 treatment replicates.
