BYPASS 1 (BPS1) is required for normal root and shoot development. This protein prevents constitutive production of a root mobile carotenoid-derived signaling compound that is capable of arresting shoot and leaf development [ 1 , 2 ].

ROH1 is an interactor of the exocyst subunit Exo70A1, and has been shown to be required for seed coat mucilage deposition [ 3 ].

This entry includes protein BYPASS 1 (BPS1) and protein ROH1, which are known to exhibit significant sequence similarity [ 4 ].
