Phenotypic analysis of the floral organs in MIM167d. a Phenotype of the flowers. The anthers from KA and MIM167d move out from the flowers. b Overview of the inner floral organs in KA and MIM167d lines. c Phenotype of the filament elongation. d Phenotype of the stigmas. The stamen was removed from (b). Red arrows indicate the stigmas. Bars, 2 mm. e Comparison of the stigma width. Error bars indicate the standard deviation (SD) (n = 10). **P < 0.01 (Student’s t-test). f Close-up view of the lodicules in KA and MIM167d. Bars, 100 μm. g Cell morphological features of lodicules in KA and MIM167d. Bars, 50 μm. h Comparison of the cell length and cell width from (g). Error bars indicate the standard deviation (SD) (n = 20). **P < 0.01 (Student’s t-test). (i) Transverse sections of flower in KA and MIM167d
