Schematic diagram of OsMADS50 genomic structure, positions of T-DNA insertional mutant alleles and flowering time of mutants. (a) OsMADS50 (Os03g0122600) consists of eight exons (boxes) and seven introns (lines between boxes). Gray boxes indicate 5′ and 3′ untranslated regions. Triangles are T-DNAs, which were inserted into the fifth and third introns in osmads50-1 (Line 0-153-43) and osmads50-2 (Line 3A-03367), respectively. Arrows indicate F and R primers used for amplification of 344-base pair (bp) cDNA. LB is left border of T-DNA. (b) Days to heading in osmads50-1 and osmads50-2 plants under controlled LD (14 h light). (c) Days to heading in osmads50-1 and osmads50-2 plants under controlled SD (10 h light). Days to heading was scored when first panicle bolted. Error bars indicate standard deviations; n = 8 to 16 plants. DAG, days after germination; LD, long day; SD, short day; WT, wild type.
