Plantphysiol 2002;130:1827-1836 ©2002 by American Society of Plant Biologists Scanning electron micrographs of various floral organs observed in 35S::LMADS2 and 35S::EgMADS1 transgenic Arabidopsis plants. Tzeng T et al. Plantphysiol 2002;130:1827-1836 ©2002 by American Society of Plant Biologists Alignment of amino acid sequence of LMADS2, EgMADS1, and related D and C functional MADS box genes. FBP7(petunia), FBP11 (petunia), AGL11 (Arabidopsis), and OsMADS13 (rice) are in D functional group; AG(Arabidopsis) and AGL1 (Arabidopsis) are in C functional group. The first underlined region is MADS box domain, whereas the second underlined region is K box domain. Amino acid residues identical to LMADS2 in this alignment are indicated as dots. Dashes were introduced to improve alignment. Phylogenetic analysis of represented plant D and C functional MADS box genes. On the basis of similarity of amino acid sequence, LMADS2 was assigned in D group
