Root Elongation in Response to Systemin and BL.

Seedlings were grown with or without treatment and root length was recorded after 7 d.

(A) Seedlings grown with varying concentrations of BL with or without 10 nM systemin treatment.

(B) Seedlings were grown on medium containing different levels of systemin with or without 1 nM BL.

(C) Response of mutant and Sl BRI1 transformed plants to systemin. Seedlings were grown on medium with or without the addition of 10 nM systemin and root length recorded. Plants analyzed are S. pimpinellifolium, cu3, pSl BRI1:Sl BRI1 transformed into cu3, S. lycopersicum cv Moneymaker (MM), S. lycopersicum cv Ailsa Craig (AC), S. lycopersicum cv Castlemart (CM), d^x, abs, def1, spr2, and Nr. Asterisks indicate P < 0.001. Error bars indicate se from the mean (n = 10).
