Fig 3. LaCl₃ inhibits DMBQ perception in Striga asiatica.

(A) Seedlings were treated with 10 μM DMBQ and/or 10 μM LaCl₃ or with t-butyl-BQ for 1 hour then loaded with Fluo-4 AM and imaged for calcium-dependent fluorescence. (B) Seedlings were incubated with 10 μM DMBQ for the indicated time period then loaded with Fluo-4 AM and imaged for calcium dependent fluorescence. All experiments conducted on day-old seedlings of S. asiatica in triplicate with results expressed as average ± SD. Samples with different letters are statistically distinct from one another (p<0.05) based on a Tukey’s post-hoc test.
