DESCRIPTION:The evolution of 3-dimensional (3D) growth coincided with the 
 colonization of land by plants approximately 470 million years ago. The ac
 quisition of apical cells that could cleave in three planes\, rather than 
 just one or two\, allowed plants to develop the characteristics required t
 o successfully survive and reproduce on land (e.g.\, roots\, vasculature\,
  seeds). 3D growth is an invariable and fundamental feature of all land pl
 ants\, and the diverse morphologies exhibited across the globe are a resul
 t of the differential regulation of 3D growth processes. Yet\, we know ver
 y little about how 3D growth is regulated at the genetic level. In many pl
 ants\, 3D growth is initiated during the first few divisions of the zygote
 \, and therefore\, the genetic basis cannot be dissected because mutants d
 o not survive. However\, in mosses\, which are representatives of the earl
 iest land plants\, 3D shoot growth is preceded by a 2D filamentous phase t
 hat can be maintained indefinitely. Using forward genetics\, we have isola
 ted many developmental mutants that fail to establish and/or maintain 3D g
 rowth. This has been a powerful and unbiased approach that has enabled us 
 to identify\, and functionally characterize novel regulators of the 2D to 
 3D growth transition. In this talk\, I will describe the identification an
 d characterization of our recently generated ‘no gametophores’ mutants
