From: The ABA receptor PYL9 together with PYL8 plays an important role in regulating lateral root growth
pyl8-1pyl9 double mutant shows a prolonged quiescence phase compared to pyl8-1 on ABA-containing medium.
(a) Average and total lateral root lengths of Col-0, pyl8-1 and pyl8-1pyl9 mutants under different concentrations of ABA. Lateral root length of 7 dpt seedlings grown on ABA media were measured. The concentrations of ABA in the medium are as indicated. Error bars indicate s.e.m. (n = 25 seedlings, 5 independent experiments). *P < 0.05, **P < 0.01, Student’s t test. Asterisks indicate comparison between pyl8-1 and pyl8-1pyl9. P-values were adjusted for multiple comparisons by “Benjamini & Hochberg” method. (b) Pie charts of the percentage of quiescent lateral roots for the indicated number of days on seedlings on control medium and medium with ABA (n = 25 seedlings per condition, 5 independent experiments). The proportion of quiescence greater than 3 days of pyl8-1 is significantly less than that of pyl8-1pyl9 (p-value < 0.05, one-tailed binomial test).
