MPF1-like gene expression. a Analysis of STMADS11 and MPF1 expression by Northern blotting. ACTIN was used as a loading control. Total RNAs were extracted from leaves (L), sepals, petals, stamens and carpels from buds (B), small buds (sB), large buds (lB), flowers (F), young flowers (yF) or mature flowers (mF), and young fruits (yFr), large fruits (lFr) and old fruits (oFr), respectively. b Functional promoter analysis: GUS expression pattern in STMADS11:GUS (upper) and MPF1:GUS (lower) transgenic Arabidopsis lines. GUS signals are in leaf, inflorescence (flower buds), mature flower and silique, but not in ovary and seeds (from left to right)
