Metaphase I in a diploid lily pollen mother cell. The nuclear envelope is gone and the 12 bivalents can be seen lined up on the metaphase I plate. Counting from the top left and moving to bottom righ...

Scanning electron microscope image of Penta lanceolata anther (pollen bearing part of stamen).

Hedgehog (Hh, red) is transcribed in apical cells of the Drosophila wild-type germarium (CIL# 13755, 13744). In the absence of boi (boi[e] mutant), Hh protein is redistributed from apical cells to the...

Hedgehog (Hh, red) is transcribed in apical cells of the Drosophila wild-type germarium (CIL# 13755 and this image). In the absence of boi (boi[e] mutant), Hh protein is redistributed from apical cell...

In the absence of boi (boi[e] mutant), Hedgehog (Hh, red) is redistributed from apical cells to the extracellular space of the local follicle stem cell niche (CIL# 13744, 13745). Expression of a mutan...

Prophase I of meiosis, diakinesis substage in a diploid lily pollen mother cell. Nucleoli are not visible. The 24 chromosomes have condensed, and are each paired with their homolog to form the 12 bi...

Model of the structure of the synaptonemal complex (SC) in Drosophila females based on EM immunolocalization of SC components C(3)G and C(2)M.
