(Submitter supplied) Heat stress is a common stress for plants. Long heat stress can triger a series of biological responses. RNA-seq is a useful method to profile RNA dynamics in creatures. Here we profiles the RNA dynamics in heat stressed Arabidopsis. These data will help us understanding the stress response mechanism in plants.

(Submitter supplied) The R-loop is a common chromatin feature presented from prokaryotic to eukaryotic genomes and has been revealed to be involved in multiple cellular processes and associated with many human diseases. Here, we take the advantage of our recently developed ssDRIP method to profile genome-wide R-loop levels and provided a first-hand R-loop atlas during Arabidopsis development and in response to various environmental factors.

(Submitter supplied) We applied a tRNA-specific sequencing pipeline to analyze tRNA expression during infection of MC57G fibroblasts with the gammaherpesvirus MHV68. We find that expression of 14% of tRNA genes is significantly upregulated during infection. By mapping reads to either premature tRNA (pre-tRNA) or mature tRNA sequences, we find that increased expression of tRNA genes is manifested at the level of the pre-tRNA only, indicating a homeostatic mechanism to maintain the size and composition of mature tRNA pools.

(Submitter supplied) The goal of this study is to investigate a chromatin-based mechanism that suppresses intragenic initiation of RNAPII transcription in A.thaliana. We demonstrate that RNAPII transcription across gene promoters represses their function in plants. The FACT histone chaperone complex is required for this repression mechanism by co-transcriptionally enforcing elevated levels of H3K4me1 at repressed intragenic promoters;

(Submitter supplied) Inspired by the important roles of the special chromatin structure R-loops, here we report a new method, ssDRIP-seq, for genome-wide identification of R-loops, and demonstrate its high efficiency, low bias, and strand-specificity when profiling the R-loops in Arabidopsis. Using this single-strand DNA ligation based library construction technique, we find that Arabidopsis R-loops are formed in both the sense and antisense orientations of genes, and prefer both AT and GC skews. more...

(Submitter supplied) Serine phosphorylation of conserved Y1S2P3T4S5P6S7 repeats of RNA polymerase II carboxy-terminal domain (RNAPII CTD) plays a central role in the regulation of transcription and co-transcriptional RNA processing. Maintenance of CTD phosphoserine-7 mark in Arabidopsis requires the CDKF;1 kinase, which mediates in vivo activation of downstream-acting CDKD CTD kinase family. Knockout mutations of CDKF;1 lead to over 50% reduction of RNAPII CTD Ser-7 phosphorylation as early as 7 days after germination in seedlings. more...

(Submitter supplied) Purpose: Determine whether Cdk1 only regulates a specific subset of tDNAs, or whether Cdk1 has a more global impact on tDNA expression; Method: We study the expression of tRNA genes in WT cells and cdk1-as1 mutants during S phase by small-RNAseq; Result: We found that expression of at least 77% of all tDNAs is significantly downregulated in S-phase in the cdk1-as1 mutant compared with the WT strain; Conclussions: Cdk1 promotes transcription of the majority of tRNA genes during the cell cycle.

(Submitter supplied) Ambient temperature is one of the most important environment factors that direct all organisms for morphogenesis, metabolisms and growth. Plants have evolved efficient mechanisms adapting temperature fluctuation such as heat stress response (HSR). Although transcriptional regulatory network of plant HSR has been established, little is known on the genome-wide transcriptional changes within first several minutes upon heat shock (HS). more...

(Submitter supplied) The expresion of dominant negative version of Arabidopsis TFIIS (TFIISmut) in plants lacking funtional TFIIS leads to severe growth defects. The genome-wide analysis of transcriptomic changes upon TFIISmut expression was performed by RNA-seq to better understand the biological importance of TFIIS. 10DAS seedlings of transgenic lines carring inducible GFP-TFIIS or GFP-TFIISmut transgenes were studied by RNA-seq following plants exposure to 24h b-estradiol or EtOH (mock) induction.

The genome-wide analysis of changes in active RNAPII occupancy upon TFIISmut expression was determined using ChIP-seq in order to better understand the biological importance of TFIIS. 10DAS seedlings of transgenic lines carring inducible GFP-TFIIS or GFP-TFIISmut transgenes were studied by ChIP-seq following plants exposure to 24h b-estradiol or EtOH (mock) induction.

Chromatin Immuno-precipitation (ChIP) was performed for FLAG tagged version of pol III subunit RPC128 after crosslinking the log-phase cells with formaldehyde. MOCK and IP DNA was sequenced and coverage of pol III was calculated at each base of the genome.

(Submitter supplied) Transcription of the eukaryotic genomes is carried out by three distinct RNA polymerases I, II and III whereby each polymerase is thought to independently transcribe a distinct set of genes. To investigate a possible relationship of RNA polymerases II and III we mapped their in vivo binding sites throughout the human genome using ChIP Seq in two different cell lines, GM12878 and K562 cells. Pol III was found to bind near many known genes as well as several novel genes. more...

(Submitter supplied) Proto-oncogene c-myc encodes a bHLH leucine-zipper containing transcription factor which has a DNA binding domain and a transactivation domain. Myc can dimerize with other factors like Max, Mad, Mnt and Miz and can influence transcription of genes. The c-myc oncogene contributes to the genesis of a wide variety of human tumors. A higher than normal level of c-myc gene expression has been observed in 50-80% of colon and breast cancers and a large proportion of human mortality from cancer is caused by abnormal expression of c-myc. more...
