Enhanced callus-forming capacity of pericycle in kcs1 mutants. (A and B) Callus-forming phenotype (A) and cytological characteristics (B) in the roots of WT, kcs1-2, and kcs1-5 seedlings on CIM. (Scale bars: 1 cm in A, 50 µm in B.) (C) Callus formation in WT, kcs1-2, and kcs1-2 plants carrying a pKCS1::KCS1 construct. Here 7-d-old seedlings were incubated on CIM for 12 d. (Scale bar: 1 cm.) (D) Lateral root initiates in 10-d-old WT, kcs1-2, and kcs1-5 seedlings. n = 18. Error bars are SD. (E) Accumulation of KCS1 in the roots of transgenic pKCS1::KCS1:GFP and pKCS1::KCS1:GFP slr plants. (Scale bar: 50 µm.)
