Extended Data Fig. 10: Inhibition of aerenchyma and iron plaque formation via disruption of strigolactone biosynthesis/signaling and ABA signaling respectively.
From: Carotenoid biosynthesis drives root plasticity through aerenchyma and iron plaque formation in rice
a, Strigolactone (SL) biosynthesis and signaling pathway illustrating the role of D17, D10 and D14. b, Root length SL biosynthesis and signaling mutants. Data are shown as means ± SE (n = 5 roots). P values were obtained using the two-tailed Student’s t-test. c, Aerenchyma (%) in 7 cm-long adventitious roots of 3-week-old SL mutants at 2-3 cm and 4-5 cm from the tip. Data are shown as means ± SE (n = 15 root cross sections). P values were obtained using the Welch’s t-test. d, Representative root cross section demonstrating reduction in aerenchyma in SL mutants. Scale bars, 100 µm. e, Iron plaque induction in SL mutants. Scale bars, 1 cm. f, Inhibition of iron plaque formation in Kitaake roots in response to ABA Antagonist 1(AA1). Red arrowheads indicate iron plaque forming adventitious roots. Scale bars, 2 cm.
