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.

MERISTEM ACTIVITYLESS1 (MAL1) is involved in crown root development through the maintenance of meristem size in rice

Project description:Rice MERISTEM ACTIVITYLESS1 (MAL1) is an RING-H2 finger domain (RFD) contained gene. To elucidate the molecular functions of MAL1 during crown root development, we generated MAL1 knock-down transgenic plants. MAL1 RNA interfering (RNAi) transgenic plants exhibited shorter crown root length and less crown root number phenotype accompanied by low cell division rate.Here we sought to find the downstream genes of OsMAL1 in rice crown root tip

A Redox-Dependent Pathway for Regulating Reversible HDACs Synchronizes Crown Root Development in Rice

Project description:As a signal molecular in aerobic organism, how reactive oxygen species (ROS) regulates normal life is a fundamental biological question. Locally accumulated ROS have been reported to balance cell division and differentiation in root apical meristem. However, the underlying molecular mechanism is unclear. Here, we reveal that developmentally produced H2O2 in plant root apical meristem (RAM) triggers reversible acetylation modification of proteins which involved in protein synthesis and cell proliferation. WOX11, an essential transcription factor for crown roots (CRs) formation, modulates ROS homeostasis by directly regulating class III peroxidases. HDACs (histone deacetylases) sense cellular redox status to enhance their enzyme activities, which drives protein acetylation level alterations in rice roots. Oxidation-dependent on WOX11 triggered protein acetylation modification leads to a robust root system in rice. Our study revealed a novel regulatory mechanism which cellular redox status via a WOX11-dependent manner regulates protein acetylation during rice crown root development. The molecular link between the redox status and HDACs activities through WOX11-dependent pathway may provide new insight into which plants exploit developmentally produced ROS to direct organogenesis. Additionally, HDACs reversible enzyme activity via redox-regulated endows with the flexibility of protein modification control in dealing with developmental and changing environmental cues.

Oryza sativa Japonica Group transcriptome sequencing

Project description:Phosphate starvation/sufficient rice seedling, root or shoot Pi-starvation or Pi-sufficient stresses responsible rice genes, including previously unannotated genes were identified by Illumina mRNA-seq technology. 53 million reads from Pi-starvation or Pi-sufficient root or shoot tissues were uniquely mapped to the rice genome, and these included 40574 RAP3 transcripts in root and 39748 RAP3 transcripts in shoot. We compared our mRNA-seq expression data with that from Rice 44K oligomicroarray, and about 95.5% (root) and 95.4% (shoot) transcripts supported by the array were confirmed expression both by the array and by mRNA-seq, Moreover, 11888 (root) and 11098 (shoot) RAP genes which were not supported by array, were evidenced expression with mRNA-seq. Furthermore, we discovered 8590 (root) and 8193 (shoot) previously unannotated transcripts upon Pi-starvation and/or Pi-sufficient.

The transcriptomic landscapes of rice cultivars with diverse root system architectures grown in upland field conditions [DAP-seq]

Project description:Genomic diversity is a source of transcriptomic and phenotypic diversities. Although genomic variations in rice (Oryza sativa) accessions have been extensively analyzed, information of transcriptomic and phenotypic variations, especially for below-ground variations, are limited. Here, we report the diversities of above- and below-ground traits and transcriptomes in highly diversified 61 rice accessions grown in the upland-field. We found that phenotypic variations were explained by four principal components and that tiller numbers and crown root diameters could summarize admixture groups. Transcriptome analysis revealed that admixture-group-associated differentially expressed genes were enriched with stress response related genes, suggesting that admixture groups have distinct stress response mechanisms. Root growth was negatively correlated with auxin inducible genes, suggesting the association between auxin signaling and mild drought stress. Negative correlation between crown root diameters and stress response related genes suggested that thicker crown root diameter is associated with mild drought stress tolerance. Finally co-expression network analysis implemented with DAP-seq analysis identified phytohormone signaling network and key transcription factors negatively regulating crown root diameters. Our datasets would serve as an important resource for understanding genomic and transcriptomic basis of phenotypic variations under the upland-field condition.

Genome-wide transcriptome of rice laser-microdissected crown root primordia reveals genes expressed specifically during the early differentiation stages of crown roots

Project description:Crown roots constitute the main part of the rice root system. Several key genes involved in crown root initiation and development have been identified by genetics and functional genomics approaches. Nevertheless these approaches are impaired by gene function redundancy and mutant lethality. To overcome these limitations, genome-wide transcriptome analysis can help to identify genes involved in crown root formation and early development. In this study we aimed to identify the genes speciffically expressed in developing crown root primordia in comparison with adjacent cortex tissue of stem at three different developmental stages before emergence from the stem. For this, we used Laser Capture Microdissection to collect crown root primordia in the stem base of 8-day-old rice seedlings. Affymetrix microarrays were processed in the Microarray Core Facility “Transcriptome“ of the Institute in Regenerative Medicine and Biotherapy, CHU de Montpellier-INSERM-UM Montpellier, http://irmb.chu-montpellier.fr/ .

Overexpression of OsbHLH044 transcription factor controls a negative regulatory module associated with plant cell death and stress inhibition in rice crown root development

Project description:Crown roots constitute the main part of the rice root system. Several key genes involved in crown root initiation and development have been identified by genetics and functional genomics approaches. The CROWN ROOTLESS1 (CRL1) transcription factor is necessary for crown root initiation in rice. The basic helix-loop-helix 044 (OsbHLH044) transcription factor was identified as a CRL1-regulated gene. In this study, we aimed to determine OsbHLH044-regulated genes, with transcriptome analysis of OsbHLH44 overexpressing plants in crl1 mutant background. We analysed the transcriptional profile of overexpressing lines stem bases in comparison with corresponding null segregant sister control lines. Affymetrix microarrays were processed in the Microarray Core Facility “Transcriptome“ of the Institute in Regenerative Medicine and Biotherapy, CHU de Montpellier-INSERM-UM Montpellier, http://irmb.chu-montpellier.fr/ .
