The many functions of ERECTA.

The Arabidopsis thaliana accession Landsberg erecta contains an induced mutation in the leucine-rich repeat receptor-like Ser/Thr kinase gene ERECTA. Landsberg erecta is commonly used as a genetic background in mutant screens and in natural variation studies. Therefore, the erecta mutation is present in many loss-of-function mutants and recombinant inbred lines. Information on how the absence of functional ERECTA affects the interpretation of obtained phenotypic results is scattered. In this report we inventoried ERECTA functions and highlight ERECTA as a pleiotropic regulator of developmental and physiological processes, as well as a modulator of responses to environmental stimuli.
