Fig. 2. lmi1 lfy-10 meristem identity phenotypes. (A-C) Meristem identity and flowering time of lmi1 lfy-10 double mutants compared with the weak lfy-10 allele, the intermediate lfy-9 allele, and the lfy-1 null allele. Secondary inflorescence (A) and bract numbers (B) were counted, as well as the number of rosette leaves formed (C). Shown are the mean values±standard error (s.e.m.) of at least 20 plants counted (10 for lfy-1). Asterisks denote statistical significance in comparison to values of lfy-10 (Student's t-test, P<0.0088). Arrow identifies the lfy-10 mutant in A-C. (D) Meristem identity transition in lfy-10 (left) and lmi1-1 lfy-10 (right). The arrowhead indicates the position of the first flower formed. (E) Flowers of lfy-10 (left) and lmi1-1 lfy-10 (right), with floral homeotic defects typical of weak lfy mutants, such as a reduction in the number of petals and stamens formed.
