- Genbank accession number
- Key message
- Furthermore, resistance to cold stress in the transgenic plants overexpressing OsCycB1;1 was also enhanced
- We show that OsMYB3R-2 specifically bound to a mitosis-specific activator cis-element, (T/C)C(T/C)AACGG(T/C)(T/C)A, a conserved sequence that was found in promoters of cyclin genes such as OsCycB1;1 and OsKNOLLE2
- These results suggest that OsMYB3R-2 targets OsCycB1;1 and regulates the progress of the cell cycle during chilling stress
- Expression analysis showed that Orysa;CycB1;1 transcripts were localized in the endosperm and embryo
- The results of the knockdown of Orysa;CycB1;1 via an endosperm or an embryo-specific promoter also suggest that the enlarged embryo may be correlated to the abortive endosperm
- Our results suggest that Orysa;CycB1;1 expression is critical for endosperm formation via the regulation of mitotic division, and that the endosperm plays an important role in maintenance of embryo development in rice
- The expression of Orysa;CycB1;1 is essential for endosperm formation and causes embryo enlargement in rice
- In our current study, we show that the knockdown of Orysa;CycB1;1 in rice results in the production of abnormal seeds, which at maturity contain only an enlarged embryo

- CPT1, CycB1;1~OsCycB1;1, Enhanced tolerance to chilling stress in OsMYB3R-2 transgenic rice is mediated by alteration in cell cycle and ectopic expression of stress genes, OsCPT1, which may be involved in the dehydration-responsive element-binding factor 1A pathway, showed the same transcription pattern in response to cold as did OsCycB1;1 in transgenic rice
- CycB1;1~OsCycB1;1, OsMYB3R-2, Enhanced tolerance to chilling stress in OsMYB3R-2 transgenic rice is mediated by alteration in cell cycle and ectopic expression of stress genes, We show that OsMYB3R-2 specifically bound to a mitosis-specific activator cis-element, (T/C)C(T/C)AACGG(T/C)(T/C)A, a conserved sequence that was found in promoters of cyclin genes such as OsCycB1;1 and OsKNOLLE2
- CycB1;1~OsCycB1;1, OsMYB3R-2, Enhanced tolerance to chilling stress in OsMYB3R-2 transgenic rice is mediated by alteration in cell cycle and ectopic expression of stress genes, In addition, overexpression of OsMYB3R-2 in rice led to higher transcript levels of several G2/M phase-specific genes, including OsCycB1;1, OsCycB2;1, OsCycB2;2, and OsCDC20
- CycB1;1~OsCycB1;1, OsMYB3R-2, Enhanced tolerance to chilling stress in OsMYB3R-2 transgenic rice is mediated by alteration in cell cycle and ectopic expression of stress genes, The level of cellular free proline was increased in the overexpressed rice lines of OsMYB3R-2 and OsCycB1;1 transgenic plants compared with wild-type plants under the cold treatment
- CycB1;1~OsCycB1;1, OsMYB3R-2, Enhanced tolerance to chilling stress in OsMYB3R-2 transgenic rice is mediated by alteration in cell cycle and ectopic expression of stress genes, These results suggest that OsMYB3R-2 targets OsCycB1;1 and regulates the progress of the cell cycle during chilling stress
- CycB1;1~OsCycB1;1, NIGT1, NIGT1 represses plant growth and mitigates phosphate starvation signaling to balance the growth response tradeoff in rice., We further demonstrate that NIGT1 constrains shoot growth by repressing the expression of growth-related regulatory genes, including brassinolide signal transduction master regulator BZR1, cell division regulator CYCB1;1, and DNA replication regulator PSF3
