Analysis of a N-6 adenosine methylation deficient plant

ABSTRACT: The embryo lethal adenosine methylase tDNA knockout line SALK_074069 was partially complemented with its cDNA driven by the embryo specific ABI3 promoter (A6 lines). The plants have reduced adenosine methylation and show pleiotropic phenotypes. Rosette leaves were harvested from 3 week old plants, both wild-type and mutant plants in triplicate and analysed using the Affymetrix ATH1 array.

Analysis of a N-6 adenosine methylation deficient plant

Project description:The embryo lethal adenosine methylase tDNA knockout line SALK_074069 was partially complemented with its cDNA driven by the embryo specific ABI3 promoter (A6 lines). The plants have reduced adenosine methylation and show pleiotropic phenotypes. Rosette leaves were harvested from 3 week old plants, both wild-type and mutant plants in triplicate and analysed using the Affymetrix ATH1 array. The 3rd to 6th rosette leaves were harvested in triplicate from 3 week old wild-type and mutant plants (A6). Total RNA was extracted and hybridised to the Affymetrix ATH1 array.

mRNA adenosine methylase (MTA) deposits m6A on pri-miRNAs to modulate miRNA biogenesis in Arabidopsis thaliana [smallRNAs]

Project description:In order to assess the possible effects of m6A on miRNA biogenesis we performed small RNA (sRNA) sequencing to compare their levels in WT Col-0 plants to those in mutant lines with severely reduced m6A levels. The reduced mta line contains MTA cDNA under the ABI3 promoter in MTA null mutant background (ABI3:MTA) and ABI3 being an embryo specific promoter rescues the embryo lethal phenotype of MTA knockout while keeping the levels of MTA in mature plants severely low34. sRNAs isolated from 4 week old WT and mta plants were used to make libraries that were sequenced using HiSeq® (Illumina) and the results were analyzed using NOISeq package in R-Studio.

wt and opr3 control and systemic wounding

Project description:wt plants (ws) and opr3 mutant plants were wounded Half of the rosette leaves of 6 weeks old plants were wounded by clamping a tweezers across the midvein. RNA was extracted from control and systemic leaves 2 h after wounding, and was subject to affymetrix ATH1 chip.

What is the transcriptomic contrast between a TDNA-mutant and its respective wild-type from young Arabidopsis rosette?

Project description:ra15-07_burxcol_465 - burxcol-465 - What is the transcriptomic contrast between a TDNA-mutant and its respective wild-type from young rosette grown in precisely-controlled conditions on our phenotyping robot (Phenoscope)? - The candidate gene (AT1G36310) was identified through QTL mapping and cloning for rosette leaf growth trait in a Bur x Col RIL set. It corresponds to a medium effect on growth and a major effect on other traits (leaf colour and pigments). We are now exploiting an independent TDNA-insertion line (SALK_135308) in the Col-0 background) to study its effect in a simple genetic context. This is a simple comparison between homozygous T-DNA (2 lines) and their respective WT (2 lines).

DCL4 Functional Analysis

Project description:Rosette leaves (5-8) and inflorescence stages (1-12) from dcl1-7, rdr6-15, and dcl4-2 mutants, involved in Arabidopsis small RNA metabolism. Three biological replicates of each mutant comprising at least 9 independent plants were harvested, and the expression profiles were determined using Affymetrix ATH1 arrays. Comparisons among the sample groups allow the identification of genes regulated by small RNAs (microRNAs and trans-acting siRNAs). Keywords: other

mRNA ADENOSINE METHYLASE promotes drought tolerance through N6-methyladenosine-dependent and independent impacts on mRNA regulation in Arabidopsis

Project description:• Among many mRNA modifications, adenine methylation at the N6 position (N6-methyladenosine, m6A) is known to affect mRNA biology extensively. The influence of m6A has yet to be assessed under drought, one of the most impactful abiotic stresses. • We show that Arabidopsis thaliana (L.) Heynh. (Arabidopsis) plants lacking mRNA ADENOSINE METHYLASE (MTA) are drought sensitive. Subsequently, we comprehensively assess the impacts of MTA-dependent m6A changes during drought on mRNA abundance, stability, and translation in Arabidopsis. • During drought, there is a global trend towards hyper-methylation of many protein-coding transcripts that does not occur in mta. We also observe complex regulation of m6A at a transcript-specific level, possibly reflecting compensation by other m6A components. Importantly, a subset of transcripts that are hyper-methylated in an MTA-dependent manner exhibited reduced turnover and translation in mta, compared to wild-type plants, during drought. Additionally, MTA impacts transcript stability and translation independently of m6A. We also correlate drought-associated deposition of m6A with increased translation of modulators of drought response, such as RD29A, COR47, COR413, ALDH2B, ERD7, and ABF4 in WT, which is impaired in mta. • m6A is dynamic during drought and, alongside MTA, promotes tolerance by regulating drought-responsive changes in transcript turnover and translation.

Rat MeDIP Array, naïve, epileptic, and adenosine treated

Project description:Epilepsy causes altered gene expression; transient adenosine treatment inhibits progression of epileptogenesis Hippocampus of epileptic rat is hypermethylated compared to naïve; adenosine treatment causes hypomethylation Metylation state in epileptic rats (9 weeks post kainic acid induced status epilepticus) was compared to naïve (untreated) rats and epileptic rats treated with adenosine for 5 days
