Extended Data Fig. 8: Phosphorylation of SWEET11 contributes to root growth under drought stress.
From: Phosphorylation of SWEET sucrose transporters regulates plant root:shoot ratio under drought
a, Vertical sections of representative root systems of Col-0 wild-type, sweet11/12 mutant, and SWEET11pro::SWEET11-HA transgenic plants expressing wild-type and mutated SWEET11 in the sweet11/12 mutant background, grown in well-watered or arid soil for 30 days. Red lines: traced roots from the image; red bars, 5 cm. The experiments in (a) were repeated independently at least three times with similar results. b-e, Fresh and dry weight in roots (b,d) and shoots (c,e) of Col-0 wild-type, sweet11/12 mutant and SWEET11pro::SWEET11-HA transgenic plants expressing wild-type and mutated SWEET11 in the sweet11/12 mutant background, without or with mannitol, PEG or ABA treatments. Error bars indicate SEM (n = 10 seedlings). Student’s t-test (two-sided). f, Representative images of Col-0 wild-type, sweet11/12 mutant and SWEET11pro::SWEET11-HA transgenic plants expressing wild-type and mutated SWEET11 in the sweet11/12 mutant background, grown under drought stress in soil. Water was withheld from 10-day-old Arabidopsis plants for 21 d under short-day conditions. The experiments in (f) were repeated independently at least three times with similar results.
