The GA-insensitive slr1-d mutant has a hypersensitive response to LT and a severe reduction in the number of sporogenous cells (SC) and pollen mother cells (PMC). Representative sections of anthers at the sporogenous cell and pollen mother cell stages are indicated for the slr1-d3 mutant and its parental TC65. At the pollen mother cell stage, hypertrophy of tapetal cells (indicated by the red arrow) is often observed in the slr1-d3 mutant exposed to LT.
