Function
OsMADS50 and OsMADS56 , which is highly homologous to Arabidopsis SOC1, are affected by the circadian clock. Under long days, OsMADS50 serves as a flowering activator by controlling various floral regulators such as OsMADS1, OsMADS14, OsMADS15, OsMADS18 and Hd3a. But OsMADS50 and OsMADS56 function antagonistically in regulating LD-dependent flowering by controlling expression of OsLFL1 and Ehd1. MATERIALS. So OsMADS56 is an LD-specific floral repressor.OsMADS50 and OsMADS56 form a complex that regulates downstream target genes in order to regulate the Rice's flowering time.
interference
In those Ehd1-RNAi plants, mRNA levels of both OsMADS56 and OsMADS50 were unchanged,indicating that OsMADS50 and OsMADS56 are upstream of Ehd1.Transcript levels of OsMADS56 were not altered in OsID1-RNAi plants , indicating that OsMADS56 is not hypostatic to OsID1. The level of Hd1 transcript was not affected in osmads50mutant and 56OX transgenic plants. T-DNA insertional knockdown plants for Hd1 reveals that mRNA levels of these two MADS genes in the mutants were unaltered under both SD and LD conditions,thus the LD-flowering pathway mediated by these two MADS genes is independent of Hd1.
Expression
(1)Real-time RT-PCR analyses indicates that OsMADS56 transcript levels were low at the seedling stage
but gradually increased to a maximum at 4 weeks after
germination as the observation made by CHOONG-HWAN RYU1 etc. (fig.3b)
(2)OsMADS56 and OsMADS50 control the Rice's flowering time through regulating their communal downstream genes OsLFL1-Ehd1 .The expression patterns of Ehd1, Hd3a RFT1 and OsLFL1 reveal it.(fig3c-f)
(3)The mRNA levels of OsMADS50 and OsMADS56 along with other flowering regulators
such as Ehd1, Hd1 reveals that OsMADS50 and OsMADS56 also have daily rhythms.(fig9) The transcript levels of
them is similar to that of Ehd1.
(4)OsMADS56 is located on chromosome 10, and consists of eight exons that encode a typical MIKC-type MADS-box protein.
