Co-immunoprecipitation (CO-IP)
CO-IP were performed as previously described
(Fiil, Qiu, Petersen, Petersen, & Mundy,
2008). 35S:COL3-HA and 35S:COL13-GFP constructs were transformed into
EHA105 Agrobacterium cells and then used to generate 35S:COL3-HA
and 35S:COL3-HA::COL13-GFP transgenic plants. Proteins were extracted
from 18-d-old seedlings.
