Figure 2. Phenotypic characterization of TMK mutants and wild type Arabidopsis show that the TMK Genes Act Redundantly to Regulate Diverse Aspects of Plant Growth and Development.

Figure 2

(A) Four day-old light grown seedlings (wild type COL; tmk1; tmk4 double mutant; tmk1; tmk3; tmk4 triple mutant). (B) Four day-old etiolated seedlings (wild type COL; tmk1; tmk4 double mutant; tmk1; tmk3; tmk4 triple mutant). (C) 4 week-old wild-type plant. (D) 4 week-old tmk1; tmk4 double mutant. (E) 4 week-old tmk1; tmk3; tmk4 triple mutant. (F) Inflorescence of wild type (left) and quadruple mutant (right). Note sterility. (G) Developing flowers of wild type (left) and quadruple mutant (right). (H) Developing silique of wild type. (I) Developing silique of tmk1; tmk4 double mutant. (J) Developing silique of tmk1; tmk3; tmk4 triple mutant. (K) Developing silique of quadruple mutant showing infertility. (L) Rosette of four week old wild type plant. (M) Rosette of four week old tmk1; tmk4 double mutant plants. (N) Recovery of tmk1; tmk4 phenotype by gTMK1. (O) Recovery of tmk1; tmk4 phenotype by gTMK4. Scale bars: 5 mm for (A)–(G) and (L)–(O); 0.5 mm for (H)–(K).
