Fig 6. Aberrant leaf phenotype of rh7 mutants compared with WT under low temperature (12°C).
(A) The phenotype of WT and rh7 mutants germinated at 22°C for 1 week, then transferred to 12°C and incubated for another 5 weeks. (B) Cotyledons and rosette leaves of plants in (A). (C) Typical plants of WT and rh7 mutants from (A). Circle indicates slightly wrinkly surface; arrow indicates upwardly curling leaf margin. (D) Observation of rosette center of mutants from (A) by scanning electron microscopy. Asterisk indicates a needle-like leaf. Scale bars = 1 cm in (B); 5 mm in (C); 1 mm in (D, left panel) and 2 mm in (D, right panel).
