The role of GRAS proteins in plant signal transduction and development

Planta. 2004 Mar;218(5):683-92. doi: 10.1007/s00425-004-1203-z. Epub 2004 Feb 4.


GRAS proteins are a recently discovered family of plant-specific proteins named after GAI, RGA and SCR, the first three of its members isolated. Although the Arabidopsis genome encodes at least 33 GRAS protein family members only a few GRAS proteins have been characterized so far. However, it is becoming clear that GRAS proteins exert important roles in very diverse processes such as signal transduction, meristem maintenance and development. Here we present a survey of the different GRAS proteins and review the current knowledge of the function of individual members of this protein family.
