The leaf is the major organ involved in light perception and conversion of solar
energy into organic carbon. In order to adapt to different natural habitats,
plants have developed a variety of leaf forms, ranging from simple to compound,
with various forms of dissection. Due to the enormous cellular complexity of
leaves, understanding the mechanisms regulating development of these organs is
difficult. In recent years there has been a dramatic increase in the use of
technically advanced imaging techniques and computational modeling in studies of
leaf development. Additionally, molecular tools for manipulation of morphogenesis
were successfully used for in planta verification of developmental models.
Results of these interdisciplinary studies show that global growth patterns
influencing final leaf form are generated by cooperative action of genetic,
biochemical, and biomechanical inputs. This review summarizes recent progress in
integrative studies on leaf development and illustrates how intrinsic features of
leaves (including their cellular complexity) influence the choice of experimental
approach.
