To comprehensively define the potential plant SWI/SNF sub-complexes and their subunits organization, we started by performing immuno-purification followed by mass spectrometry analysis (IP-MS) using stable transgenic Arabidopsis lines that expressed a green fluorescent protein (GFP)-tagged ATPase subunit, BRM (Li et al., 2016), SYD (Shu et al., 2021) or MINU2 (this study), driven by its native promoter in corresponding null mutant background.
