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.
