Landsberg and cv.Columbia.MISCELLANEOUS:Loss-of-function mutants (T-DNA insertion) show a reduction in leaf size, but no apparent defect in pollen development or fertility.SIMILARITY:Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.SIMILARITY:Contains 5 LRR (leucine-rich) repeats.SIMILARITY:Contains 1 protein kinase domain.SEQUENCE CAUTION:Sequence=BAB01397.1; Type=Erroneous gene model prediction; "
