Extended Data Fig. 6: gosamt1 gosamt2 mutants display strong cell elongation and adhesion phenotypes.

(A) Quantification of etiolated hypocotyls of WT, gosamt1, gosamt2 and gosamt1 gosamt2, one to five days after germination (DAG) grown etiolated hypocotyls length grown in ½MS media and ½MS supplemented with CaCl2 to a final concentration of 15mM. Error bars correspond to SD of at least n ≥73 seedling measurements per genotype per time point. (B) WT and gosamt1 gosamt2 etiolated hypocotyls length, grown in ½MS media and ½MS supplemented with CaCl2 to a final concentration of 15mM, stained with ruthenium red. Bar 5mm. (C) Scanning electron microscopy (SEM) of WT and in MS and in MS supplemented with CaCl2 to a final concentration of 15 mM. Bar 100μm.
