Please input one-sentence summary here.
SDG724 is a class II SET domain protein and is constitutively expressed in various kinds of tissues.
Contents
Annotated Information
Funtion
- SDG724 functions as a histone methyltransferase in vitro and contributes to a major fraction of globalhistone H3 lysine 36 (H3K36) methylation in vivo[1].
- Histone Lys methylation in plants functions in biological processes such as flowering transition, floral organ development,carotenoid biosynthesis, shoot and root branching, pollen and macro-trichome development, and the brassinosteroid signaling pathway[2].
- lesions in SDG724 were responsible for the late-flowering phenotype of lvp1 plants Heading date analyses showed that the flowering time defect was rescued in thetransgenic plant lines[1].
- Long vegetative phase 1 (LVP1)/SDG724, is required for H3K36 methylation and promotes heading date in rice. The loss of function mutant lvp1 has a late flowering phenotype under both LD and SD conditions, associated with the suppressed expression of MADS50, MADS51, Ehd1, RFT1, and Hd3a. Furthermore, our results suggest a novel mechanism for the epigenetic regulation of flowering in rice, in which SDG724 mediates H3K36me2/3 deposition at the MADS50 and RFT1loci and promotes flowering through MADS50/MADS51-Ehd1-Hd3a/RFT1 pathways[3].
Expression
- Expression analyses of flowering time genes in wild-type and lvp1 mutants revealed that Early heading date1, but not Heading date1, are misregulated in lvp1 mutants. In addition, the double mutant of lvp1 with photoperiod sensitivity5 (se5) flowered later than the se5 single mutant, indicating that lvp1 delays flowering time irrespective of photoperiod[1].
- To investigate the role of SDG724 in aphotoperiod-insensitive background, lvp1 se5 double mutants were created using a se5 nonsense mutation in Nipponbare,the same genetic background as for the lvp1 mutant[1].
- Genetic analysis demonstrated that the late flowering phenotype of lvp1 segregated as a complete monogenic recessive trait.Therefore, we carefully selected 1147 extremely late-heading plants from an F2 population derived from a cross between lvp1 and Minghui 63 and used a map-based cloning strategy to identify the candidate gene[1].
- Under Beijing field conditions,lvp1 plants did not show heading even in November, 160 d after germination, when the weather became too cold for rice growth[1].
- Chromatin structure is important for eukaryotic gene expression, and histone Lys methylation has drawn special attention due to its complex role in this process[4].
- Ehd1, which encodes a B-type response regulator, is a unique transcriptionalregulator and promotes flowering by controlling FT-like gene expression independent of Hd1 under both SD and LD condi-tions in rice[5].
Evolution
- SET domain–containing proteins are well annotated and characterized in Arabidopsis[6].
- There are at least two independent flowering pathways in rice.The Heading date1 (Hd1) pathway is conserved between rice and Arabidopsis, but the Early heading date1 (Ehd1) pathway is unique to rice[5].
- RFT1 and Hd3a encode two rice florigens and are closely linked in the genome, separated by only 11.5 kb. However, RFT1 and Hd3a have functionally diverged to control the LD and SD flowering time pathways, respectively[7].
