1. Coelacanth eyes are very sensitive, and have a tapetum lucidum.

2. Male - sterility mainly results from the abnormality of mesospore, tapetum tissue and vascular bundle.

3. Each microsporangium is lined with a nutritive tissue layer called the tapetum and initially contains diploid pollen mother cells.

4. AUXIN RESPONSE FACTOR17 (ARF17) plays a crucial role in pollen wall pattern formation, tapetum development, and auxin signal transduction in Anthers

5. Anther Wall: Epidermis, endothecium, middle wall layers (2-3 layered), and the tapetum (outer and inner layers) constitute the Anther wall
