Expression of Arabidopsis cis-NAT pairs in inflorescences, leaves and roots

ABSTRACT: We systematically identified long noncoding natural antisense transcripts (lncNATs), defined as lncRNAs transcribed from the opposite DNA strand of coding or noncoding genes. We identified in total 37,238 sense-antisense transcript pairs and found 70% mRNAs are associated with antisense transcripts in Arabidopsis. To detect the expression levels of these NAT pairs, we designed an Agilent custom array, ATH NAT array, and analyzed RNA samples from Arabidopsis inflorescences, leaves and roots, with 3 biological replicates each.

Dynamic changes of Arabidopsis cis-NAT pairs during de-etiolation

Project description:We systematically identified long noncoding natural antisense transcripts (lncNATs), defined as lncRNAs transcribed from the opposite DNA strand of coding or noncoding genes. We identified in total 37,238 sense-antisense transcript pairs and found 70% mRNAs are associated with antisense transcripts in Arabidopsis. To investigate the role of NATs in response to white light treatment, we designed an Agilent custom array, ATH NAT array, and analyzed WT seedlings grown in the dark (0h) and seedlings undergoing de-etiolation in continuous white light for 1h and 6h. To obtain information on organ-specific transcriptome profiles, we further dissected seedlings into cotyledons, hypocotyls and roots. We examined the abundance of NATs in etiolated seedlings and seedlings undergoing de-etiolation in continuous white light for 1/6h. Seedlings were further dissected into cotyledons, hypocotyls and roots. RNAs from 3 biological replicates of each of the 3 organs were separately hybridized to ATH NAT arrays to profile light-regulated NAT pairs.

Expression Profiling of Arabidopsis Long Intergenic Nongcoding RNA in Inflorescences, Leaves, and Roots

Project description:Long intergenic noncoding RNAs (lincRNA) transcribed from intergenic regions of eukaryotic genomes play important roles in key biological processes; yet, plant lincRNAs remain poorly characterized. Here we profiled lincRNA expression in inflorescences, leaves and roots using ATH lincRNA v1 array. we found 92% lincRNAs could be detected in at least 2 ATH lincRNA v1 arrays and majority of the lincRNAs were expressed at levels higher than those of pri-miRNAs but lower than those of mRNAs.Using a cut-off of 2-fold change, we identified 149 lincRNAs preferentially expressed in inflorescences, 232 in leaves and 164 in roots.

Expression Profiling of Arabidopsis Long Noncoding RNAs Under Continuous Light Condition

Project description:Long intergenic noncoding RNAs (lincRNAs), Natural Antisense Transcripts (NATs), and microRNAs (miRNAs) play important roles in many biological processes. To profile circadian regulated long noncoding RNAs (lncRNAs), we grow Arabidopsis plants (Col-0) under short day SD (8h light/16h dark) condition and used the ATH lincRNA v1 array to profile lincRNA, NAT and miRNA gene expression under continuous light condition. Using JTK_CYCLE to search for cycling expression pattern of genes, we found ~900 genes encoding lincRNAs, NATs and miRNAs showed significant cycling expression patterns (Adjusted P-value < 0.05).

Identification of Arabidopsis Long Intergenic Noncoding RNA regulated by RNA-dependent RNA polymerase 2 (RDR2)

Project description:RNA-dependent RNA polymerase 2 (RDR2) is a crucial regulator of RNA-directed DNA methylation (RdDM). Recentily RDR2 was reported to regulate expression of long intergenic noncoding RNAs. Here we used ATH lincRNA v1 expression arrays to compare lincRNA expression in inflorescence tissues of rdr2-1 and WT. Among the 4,634 lincRNAs detected we found that more than 34% of them were differentially expressed, including 676 lincRNAs that were up-regulated and 890 down-regulated in rdr2-1. Inflorescences(Col-0) x Inflorescences(rdr2-1), 3 biological replicates.

Carbon-Deprivation-Driven Transcriptome Reprogramming in Detached Developmentally-Arresting Arabidopsis Inflorescences

Project description:Senescence is genetically-controlled and activated in mature tissues during ageing. However, immature plant tissues also display senescence-like symptoms when continuously exposed to adverse energy-depleting conditions. We used detached dark-held immature inflorescences of Arabidopsis thaliana to understand the metabolic reprogramming occurring in immature tissues transitioning from rapid growth to precocious senescence. Macroscopic growth of the detached inflorescences rapidly ceased upon placement in water in the dark at 21°C. Inflorescences were completely de-greened by 120 h of dark incubation and by 24 h had already lost 24% of their chlorophyll and 34% of their protein content. Comparative transcriptome profiling at 24 h revealed that inflorescences response at 24 h had a large carbon-deprivation component. Genes that positively regulate developmental senescence (ANAC092) and shade avoidance syndrome (PIF4 and PIF5) were up-regulated within 24 h. Mutations in these genes delayed de-greening of the inflorescences. Their up-regulation was suppressed in dark-held inflorescences by glucose treatment, which promoted macroscopic growth and development and inhibited de-greening of the inflorescences. Detached inflorescences held in the dark for 4 days were still able to re-initiat development to produce siliques upon being brought out to light indicating the transcriptional reprogramming at 24 h was adaptive and reversible. Our results suggest that the response of detached immature tissues to dark storage involves interactions between carbohydrate status sensing and light deprivation signaling and that the dark adaptive response of the tissues appears to utilize some of the same key regulators as developmental senescence.
