HERK1, HERK2, THE1 and FER are regulated by BL/BES1 and are required for cell elongation. (A) The expression of CrRLK family RLKs by BL in WT and bes1-D mutant. Microarrays were performed with 2-week-old seedlings with or without BL treatment (1 µM, 3 hr). At5g38990 and At5g39000 have the same probe set in Affymetrix ATH1 Genome arrays, so only the former is shown. (B) BR responses of the indicated mutants at the seedling stage, performed as described.9 (C) Plant phenotypes of 24-day-old adult plants. The bar represents 10 mm. (D) Petiole lengths of the sixth leaf in WT and mutants. Averages and standard deviations from 10 plants are shown. (E) A model for HERK signaling and its crosstalk with BR pathway.
