	Distance to root tip	Nipponbare	Tianfeng 202	Liaohan 109
Endodermis	20 mm	Deposition of SL in a few endodermal cells (Fig. 1J)	Deposition of SL in some endodermal cells (Fig. 1K)	Deposition of SL in most endodermal cells (Fig. 1L)
	50 mm	SL along the length of radial walls in a few endodermal cells (Fig. 1M)	SL along the length of radial walls in some endodermal cells (Fig. 1N)	SL filled most of the length of radial walls in most endodermal cells (Fig. 1O)
