- Key message
- CHR729 Is a CHD3 Protein That Controls Seedling Development in Rice.
- These results suggest that the rice CHD3 protein CHR729 plays an important role in many aspects of seedling development and controls this development via the gibberellin pathway
- CHR729 encoded a nuclear protein and was expressed in almost all organs
- Realtime RT-PCR analysis showed that CRL6 was most highly expressed in the stem base region where crown roots initiated
- Histological analysis showed that CRL6 influences crown root formation by regulating primordial initiation and development
- Our results provide evidence that CRL6 plays an important role in crown root development in rice via auxin-related signaling pathway
- In addition, auxin-action inhibited phenotype was observed during crl6 development
- Map-based cloning and subsequent complementation tests verified that the CRL6 gene encodes a member of the large chromodomain, helicase/ATPase, and DNA-binding domain (CHD) family protein
- Our results suggest that RFS is required for many aspects of plant development and its function is closely associated with epigenetic regulation of genes that modulate ROS homeostasis
- Connection
- CHR729~OsCHD3~CRL6~RFS, OsCLF~SDG711, Histone H3K4me3 and H3K27me3 regulatory genes control stable transmission of an epimutation in rice., Here we show that maintenance of a stably hypomethylated active epiallele in rice required a CHD3 protein (CHR729) and that over-expression of an H3K4me3 demethylase (JMJ703) or H3K27me3 methyltransferase (SDG711) could stably resilence the epiallele
- CHR729~OsCHD3~CRL6~RFS, JMJ703~OsJMJ703, A Chromodomain-Helicase-DNA-like Binding Factor Functions in Chromatin Modification and Gene Regulation., Genetic and genomic analysis revealed that CHR729 and JMJ703, an H3K4 demethylase, had agonistic, antagonistic and independent functions in modulating H3K4me3 and expression of subsets of genes
- CHR729~OsCHD3~CRL6~RFS, SPR9, SPR9 encodes a 60 S ribosomal protein that modulates panicle spreading and affects resistance to false smut in rice Oryza sativa. L., RESULTS: In this study, we show that a simple spreading panicle change in rice panicle shape, controlled by the Spreading Panicle 9 (SPR9) locus, also has a significant impact on the resistance to rice false smut (RFS)
- CHR729~OsCHD3~CRL6~RFS, SPR9, SPR9 encodes a 60 S ribosomal protein that modulates panicle spreading and affects resistance to false smut in rice Oryza sativa. L., Interestingly, the spr9 mutant was found to improve resistance to RFS without affecting major agronomic traits
