From: OsLAP6/OsPKS1, an orthologue of Arabidopsis PKSA/LAP6, is critical for proper pollen exine formation
SEM and TEM observation for the WT and oslap6 anther and pollen. a-l SEM analysis of the surfaces of anthers and pollen grains in the WT and oslap6 at stage 12. m-p TEM observation of pollen exine in the WT and oslap6 at stage 13. a and b Anthers of WT and oslap6. c and e Anther epidermis of WT and oslap6. d and f The enlarged images of epidermal surface of the WT and oslap6 anthers. g and j The inner surface of the WT and oslap6 anthers. h and k Pollen grains in the WT and oslap6 anthers. i and l Outer surface of pollen grains in the WT and oslap6 anthers. m and o Ultra-thin sections of pollen in the WT and oslap6. n and p The magnified images of pollen exine in the WT and oslap6, the arrows indicate the collapsed bacula. Ba, bacula; DEx, deformed exine; DP, degenerated pollen; DUb, deformed Ubisch body; Ex, exine; In, intine; GP, germination pore; MP, mature pollen; Ne, nexine; Te, tectum; Ub, Ubisch body; Scale bars = 100 μm (a and b); 10 μm (c–f, h, and k); 1 μm (g, j, i, and l); 2 μm (m); 5 μm (o); 500 nm (n and p)
