If the apical meristem is removed, or has grown a sufficient distance away from an axillary bud, the axillary bud may become activated ( or more appropriately freed from hormone inhibition ).
42.
Initially, a young plant will only produce phytomers at its apical meristems but later in development, secondary meristems will begin to form and phytomers will be formed on this lateral plant growth.
43.
True leaves, however, are formed post-embryonically ( i . e . after germination ) from the shoot apical meristem, which is responsible for generating subsequent aerial portions of the plant.
44.
Dr . Meyerowitz is well known for his contributions on the genetic and molecular basis of plant hormone reception, and on the molecular mechanisms of pattern formation during flower and shoot apical meristem development.
45.
Euphyllophytes have large'true'leaves ( megaphylls ), which develop through marginal or apical meristems ( i . e ., the leaves effectively grow from the sides or the apex ).
46.
In wheat ( " Thinopyrum " ), perenniality is associated with production of a secondary set of tillers ( stems arising from the crown's apical meristem ) following the reproductive phase.
47.
Specifically, arrival of FT at the shoot apical meristem and formation of the FT / FD heterodimer is followed by the increased expression of at least one direct target gene, APETALA 1 ( AP1 ),
48.
Further work on this system has shown that the formation of flowers is triggered by PIN1-mediated local accumulations of auxin on the surface of the shoot apical meristem in the so-called L1 cell layer.
49.
In " Arabidopsis thaliana ", 3 interacting " CLAVATA " genes are required to regulate the size of the stem cell reservoir in the shoot apical meristem by controlling the rate of cell division.
50.
In botany, "'sympodial "'growth is a specialized lateral growth pattern in which the apical meristem is terminated and growth is continued by one of more lateral meristems, which repeat the process.
