Expression pattern of the HAM::GUS genes. (A) Seedling of one-week-old harbouring a HAM1::GUS fusion grown in vitro. Boxed section represents a magnification of stained root hairs. Bar: 250 μm. (B) Three week-old plant grown in vitro. Boxed section represents a close-up view on a stained trichome. Bar: 1 mm. (C) Floral tissue of a 5-week-old plant. Bar: 1 mm. (D) Section of HAM1::GUS young floral bud at the stage of tetrad. Bar: 50 μm. (E-F) cleared whole mount of young (E) and mature pollen grains (F) showing the decreased of GUS expression during the pollen maturation. Bars: 25 μm.
