Plant materials and growth conditions
The A. thaliana mutant col13 (GK657F04-023194) in the
Columbia background (Col-0) was purchased from Germany (GABI-Kat, Max
Planck Institute for Plant Breeding Research, Carl-von-Linné-Weg 10,
50829 Köln, Germany) (Rosso et al., 2003), whereas col3 was
generously provided by Professor Magnus Holm (Datta et al., 2006).
Col-0, Ws, and their F1 hybrids were used as wild-type controls. Seed
sterilization and growth were performed as previously described (Liu et
al., 2016).
