System analysis of microRNAs in the development and aluminium stress responses of the maize root system.

ABSTRACT: Four sRNA libraries were generated and sequenced from the early developmental stage of primary roots (PRY), the later developmental stage of maize primary roots (PRO), seminal roots (SR), and crown roots (CR). Through integrative analysis, we identified 501 miRNAs (246 conserved and 255 novel ones) and found that the expression patterns of miRNAs differed dramatically in different maize roots.

MicroRNAs in the development and the environmental responses of the maize root system

Project description:Four sRNA libraries were generated and sequenced from the early developmental stage of primary roots (PRY), the later developmental stage of maize primary roots (PRO), seminal roots (SR), and crown roots (CR). Through integrative analysis, we identified 501 miRNAs (246 conserved and 255 novel ones) and found that the expression patterns of miRNAs differed dramatically in different maize roots. we generated and sequenced four maize small RNA libraries from the early developmental stage of primary roots (PRY), the later developmental stage of maize primary roots (PRO), seminal roots (SR), and crown roots (CR) using Solexa high-throughput sequencing technology

The distinct transcription patterns correlate with the differential growth responses to salt stress in maize roots

Project description:We found that primary root (PR) is more resistant to salt stress compared with crown roots (CR) and seminal roots (SR). To understand better salt stress responses in maize roots, six RNA libraries were generated and sequenced from primary root (PR), primary roots under salt stress (PR-salt) , seminal roots (SR), seminal roots under salt stress (SR-salt), crown roots (CR), and crown roots under salt stress (CR-salt). Through integrative analysis, we identified 444 genes regulated by salt stress in maize roots, and found that the expression patterns of some genes and enzymes involved in important pathway under salt stress, such as reactive oxygen species scavenging, plant hormone signal perception and transduction, and compatible solutes synthesis differed dramatically in different maize roots. 16 of differentially expressed genes were selected for further validation with quantitative real time RT-PCR (qRT-PCR).We demonstrate that the expression patterns of differentially expressed genes are highly diversified in different maize roots. The differentially expressed genes are correlated with the differential growth responses to salt stress in maize roots. Our studies provide deeper insight into the molecular mechanisms about the differential growth responses of different root types in response to environmental stimuli in planta.

miRNA expression data from low nitrate culture in leaf and root of maize

Project description:Nitrate is the major source of nitrogen available for many crop plants and is often the limiting factor for plant growth and agricultural productivity especially for maize. Many studies have been done identifying the transcriptome changes under low nitrate conditions. However, the microRNAs (miRNAs) varied under nitrate limiting conditions in maize has not been reported. MiRNAs play important roles in abiotic stress responses and nutrient deprivation. We used the microarray systems to detect miRNAs responding to the chronic nitrate limiting conditions in maize leaves and roots.

Reprograming of gene expression and DNA methylation during initiation stages of the different root types in rice

Project description:Rice possesses a fibrous root system with a primary root, lateral roots and crown roots. The cellular origins and early morphologies of the three root types vary greatly, but the adult structures are remarkably similar. Previous studies have highlighted diverse mechanisms involved in rice roots formation However, the gene expression reprograming and the underling epigenetic mechanisms of cell differentiation and initiation of the different roots are not studied. Here, we analyzed spatiotemporally resolved transcriptomes and DNA methylomes during the initiation processes of the three root types using a precise laser microdissection (LM) coupled with RNA-Seq and BS-seq. The analysis reveals distinct gene expression programs during the first stages during the initiation of the three root types. DNA methylome analysis uncovers a dynamic but distinct CHH methylation reprogramming during initiation of the three roots, with a genome-wide decrease of CHH methylation in crown and lateral root initials, but an increase in embryonic root primordium. In addition, a more drastic reprogramming of CHH methylation was observed in lateral root initials. Together, the results provide stage-specific gene expression signatures of the rice roots initiation and show distinct epigenetic and gene expression reprograming during the formation of the three different root types in rice.

Digital gene expression analysis of early root infection of Sporisorium reilianum f.sp.zeae in maize based on susceptible and resistant lines

Project description:The maize smut fungus, Sporisorium reilianum f. sp. zeae, which is an important biotrophic pathogen responsible for extensive crop losses, infects maize by invading the root during the early seedling stage. In order to investigate disease-resistance mechanisms at this early seedling stage, digital gene expression (DGE) analysis, which applies a dual-enzyme approach (DpnII and NlaIII), was used to identify the transcriptional changes in roots of Huangzao4 (susceptible) and Mo17 (resistant) after inoculation with teliospores of S. reilianum. Before and after inoculation, pathogenesis-related genes were differentially regulated and enzymes involved in controlling reactive oxygen species (ROS) levels showed different activity between Huangzao4 and Mo17, which can potentially lead to changes in the growth of S. reilianum and ROS production in maize. Moreover, lignin depositions of roots were also changed differentially during root colonization of hyphae between Huangzao4 and Mo17. These results suggest that the interplays between S. reilianum and maize during the early infection stage involve many interesting transcriptional and physiological changes, which offer several novel insights for understanding the mechanisms of resistance to the fungal infection.

Histone acetyltransferase OsGCN5 palys an important role in establishing programs of cell proliferation of crown root meristem

Project description:Shoot-borne crown roots are the major root system in cereals. Previous work has shown that the Wuschel-related homeobox gene WOX11 is necessary and sufficient to promote rice crown root emergence and elongation. Here, we show that WOX11 recruits the ADA2-GCN5 histone acetyltransferase (HAT) module to activate downstream target genes in crown root meristem. OsGCN5 and OsADA2 are highly expressed in root meristem. Knockdown of OsGCN5 and OsADA2 affects crown root initiation and elongation. Here we sought to find the downstream genes of OsGCN5 in rice crown root tip.

Temporal expression study of microRNAs in crown tissues of winter wheat grown under natural growth condition

Project description:MicroRNAs (miRNAs) are single strand small non-coding RNAs that regulate target mRNAs at post-transcription level. Winter wheat (Triticum aestivum L.), is an important crop plant all over the world. Long term cold exposure (vernalization) is necessary for winter wheat transition from vegetative growth to reproductive growth, yet the involvement of miRNAs in these stages remains unknown. Therefore, we performed next generation sequencing of small RNAs profiles in crown tissues at three-leaf stage, winter dormancy stage, spring greenup stage and jointing stage.

MeDIP-seq in human lung cancer tissues

Project description:we used methylated DNA immunoprecipitation sequencing (MeDIP-Seq) to detect DNA methylation levels and lncRNA-seq to detect lncRNA expression levels in 3 lung cancer samples and 3 matched normal samples. Then 255 differentially methylated genes (DMGs) and 246 differentially expressed lncRNAs (DELs) were identified. Finally, LINC01354 was founded to be differentially methylated and predictive of transcription. Besides, the prognostic value of differential methylation related DELs was analyzed.
