Mutations in LRX genes cause aberrant plant growth. a Cotyledons of 7 days-old seedlings are gradually smaller in the lrx3 lrx4 double mutant and the lrx3 lrx4 lrx5 triple mutant compared to the wild type (Col). Roots of the same seedlings are significantly shorter in the lrx3 lrx4 lrx5 triple mutant. Error bars shown in the graph represent standard errors. Significance was tested by T-test; n ≥ 14, *: P < 0.05. b Mature plants of double and triple mutants reveal a reduction in growth compared to wild-type plants, whereas the lrx5 single mutant grows comparable to the wild type. c Sinuous structures were observed in double and triple mutant cotyledons with occasional cracks (arrows) in the epidermis of the triple mutant.
