(Submitter supplied) To elucidate the epigenetic regulation of salt-responsive genes helps to understand the underlying mechanisms that confer salt tolerance in rice. However, it is still largely unknown how epigenetic mechanisms function in regulating the salt-responsive genes in rice and other crops at a global level. In this study, we mainly focused on dynamic changes in transcriptome and histone marks between rice leaf and root tissues during salt treatment by using RNA-seq and ChIP-seq approaches. more...

(Submitter supplied) Dongxiang wild rice (Oryza rufipogon Griff.) is the progenitor of cultivated rice (Oryza sativa L.) and is well known for its superior level of tolerance against cold, drought and diseases. To date, however, little is known about the salt-tolerant character of Dongxiang wild rice. To elucidate the molecular genetic mechanisms of salt-stress tolerance in Dongxiang wild rice, the Illumina HiSeq 2000 platform was used to analyze the transcriptome profiles of the leaves and roots at the seedling stage under salt stress compared with those under normal conditions. more...

(Submitter supplied) DNA methylation and histone H3 lysine 9 dimethylation (H3K9me2) are important epigenetic repression marks for silencing transposons in heterochromatin and regulating gene expression in plant development. However, the mechanistic relationship to other repressive marks, such as histone H3 lysine 27 trimethylation (H3K27me3), is unclear. OsFIE1 (Fertilization Independent Endosperm 1) encodes an Esc-like core component of the Polycomb repressive complex 2 (PRC2), which is involved in H3K27me3-mediated gene repression. more...

(Submitter supplied) We identified and characterized a rice epigenetic mutant Epi-df which exhibits a dwarf stature and various floral defects that are inherited in a dominant fashion. We demonstrated that Epi-df participates in Polycomb repressive complex 2 (PRC2) mediated gene silencing. Epigenetic mutations results in ectopic expression of Epi-df and pleiotropic developmental defects in mutant plants. Moreover, ectopic expression of Epi-df leads to mis-regulated H3K27me3 and changed expression of hundreds of genes involved in a wide range of biological processes. more...

(Submitter supplied) Soil salinity is one of the primary causes of yield decline in rice. Pokkali (Pok) is a highly salt-tolerant landrace whereas IR29, is salt-sensitive but a widely cultivated cultivar. Comparative analysis of these genotypes may offer better understandings of the salinity tolerance mechanism. The published reports largely underscored the importance of transcriptional regulation during salt stress in these genotypes, while, the regulation at translational level is also critically important. more...

(Submitter supplied) H3K27me3 is a repressive chromatin mark of genes and is catalyzed by homologs of Enhancer of zeste [E(z)], a component of Polycomb-repressive complex 2 (PRC2), while DNA methylation that occurs in CG and non-CG (CHG and CHH, where H is A, C or T) contexts is a hallmark of transposon silencing in plants. However, relationship between H3K27me3 and DNA methylation in gene repression remains unclear. In addition, the mechanism of PRC2 recruitment to specific genes is not known in plants. more...

(Submitter supplied) 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. more...

(Submitter supplied) We used GeneChip Rice Genome Array (Affymetrix, Santa Clara, CA, USA) to identify genes that were rapidly induced by glutamate in rice roots. Transcriptomic analysis of rice roots revealed that the expression of at least 122 genes involved in metabolism, transport, signal transduction, defense, and stress responses was rapidly induced by glutamate within 30 minutes.

(Submitter supplied) Nitrogen is major nutrient for plant growth. Two forms for inorganic nitrogen are available for plant, ammonium and nitrate. External status of them affects largely plant growth and production. Generally, root is a sole organ to uptake nitrogen. Hence, identifying regulatory genes depend on nitrogen status in roots is important to improve sustainable production or rice. To isolate the candidate gene, array experiments were performed. more...

(Submitter supplied) Plasma membrane NADPH oxidases (NOXs) are major producers of reactive oxygen species (ROS) in plant cells under normal growth and stress conditions. Rice NOXs have multiple homologs but their functional mechanisms are largely unknown. We used microarrays to detail the global gene expression profiles in rice wild-type (WT, Dongjin) and a mutant osnox2 which loss the functions of OsNOX2 protein under drought and identified distinct classes of genes between the two type rice plants under both normal growth and drought stressed conditions.

(Submitter supplied) Epigenetic processes play a crucial role in the regulation of plant stress responses, but their role in plant-pathogen interactions remains poorly understood. Although histone modifying enzymes are deregulated in galls induced by root-knot nematode (RKN, Meloidogyne graminicola) in rice, their influence on plant defence and their genome-wide impact has not been comprehensively investigated. At genome-wide level, three histone marks, H3K9ac, H3K9me2 and H3K27me3 were studied by chromatin-immunoprecipitation (ChIP)-sequencing on RKN-induced galls at 3 days post inoculation. more...

(Submitter supplied) There is mounting evidence for the role of epigenetic processes in the regulation of plant responses to a wide range of external stimuli. Despite their importance, the significance of epigenetic processes in plant-pathogen interactions remain poorly understood. So far, the role of histone modifications has not been investigated at genome wide level in plant-nematode interactions, although their expression levels are altered in nematode-induced galls. more...

(Submitter supplied) To gain more insight into cellular responses to mercury, we have undertaken a large-scale analysis of the rice transcriptome during mercury stress.More transcripts were responsive to mercury during short (pooled from 1- and 3-h treatments) , as compared to long (24 h) exposures. After short exposures, these induced genes can be divided into different functional categories, mainly on the basis of cell wall formation, chemical detoxification, secondary metabolism, signal transduction and abiotic stress response. more...
