Zea mays Transcriptome or Gene expression

ABSTRACT: The classical maize mutant lazy1 (la1), displayed prostrate growth with reduced shoot gravitropism. We compared the transcriptome profile of the third node in la1-ref mutants with those in wild-type plants using RNA-SEQ to examine the genome-wide effect of the ZmLA1 gene. We generated 14.6 and 36.5 million paired-end reads from two biological samples of wild-type and la1-ref mutant plants, respectively.

Maize LAZY1 mediates shoot gravitropism and inflorescence development through regulating auxin transport, auxin signaling, and light response.

Auxin is a plant hormone that plays key roles in both shoot gravitropism and inflorescence development. However, these two processes appear to be parallel and to be regulated by distinct players. Here, we report that the maize (Zea mays) prostrate stem1 mutant, which is allelic to the classic mutant lazy plant1 (la1), displays prostrate growth with reduced shoot gravitropism and defective inflorescence development. Map-based cloning identified maize ZmLA1 as the functional ortholog of LAZY1 in r ...[more]

Genome-wide transcriptome analysis of explant regeneration in be1-3

Project description:The Arabidopsis Branching Enzyme 1 (BE1) gene encodes a putative glycoside hydrolase involved in carbohydrate metabolism. A partial loss-of-function mutation of the BE1 gene (be1-3 mutant) severely impaired adventitious shoot formation and somatic embryogenesis but not root formation in tissue culture. To gain a better understanding of the molecular mechanism underlying the in vitro plant regeneration defects caused by the BE1 gene mutation, we performed RNA sequencing analysis (RNA-seq) to examine the differential gene expression between WS and be1-3 mutant at dedifferentiation and redifferentiation stages.

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.

The Zeanome

Project description:Maize exhibits levels of structural variation (SV) of non-repeat sequences that are unprecedented among higher eukaryotes. This SV includes hundreds of copy number variants (CNVs) and thousands of presence/absence variants (PAVs). Many of the PAVs contain intact, expressed, single-copy genes that are present in one haplotype but absent from another. The goal of this project is to test the hypothesis that differences in gene copy number (both gains and losses) contribute to the extraordinary phenotypic diversity and plasticity of maize. Maize is a good model for these studies because it exhibits a rapid decay of linkage disequilibrium (LD) and because a draft genome sequence of the B73 inbred and mapping populations are available. As a first step, the Zeanome, a near-complete set of genes present in B73, other maize lines and the wild ancestor of maize (teosinte), is being defined using transcriptomic data. Note: All samples in SRA were assigned the same sample accession (SRS302561). This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.

Triticum urartu strain:PI 428198 Genome sequencing and Transcriptome or Gene expression

Project description:For this project, we have sequenced, assembled and annotated a transcriptome of a diploid wheat Triticum urartu accession PI 428198. The sequencing libraries were prepared from shoot and root tissues harvested from 2-3 week old seedlings. All sequencing was carried out on the Illumina HiSeq platform using the 100 bp pair-end protocol (248.5 million reads). The assembly was constructed using a multiple k-mer approach with a de novo assembly algorithm implemented in CLC Genomics Workbench 5.5 and additional redundancy reduction with CD-HIT and blast2cap3 programs. Open reading frames and proteins were predicted using BLASTX searches and a findorf algorithm.

Oryza sativa cultivar:Nippobare Transcriptome or Gene expression

Project description:We used RNA-Seq to systematically investigate the global transcriptomes of rice which was inoculated with viruliferous SBPH, or inoculated with insect-derived RSV or plant-derived RSV by mechanical inoculation, and generated a useful resource for the immune reaction of rice in face of different kinds of RSV. The changes in the expression of candidate transcripts may provide valuable information for future studies on molecular mechanisms of rice stripe disease.
