摘　　要：Dear Editor, Male reproductive development is an essential biological process for flowering plants and crucial for crop seed produc- tion. Formation of the male reproductive organ, the anther, involves a number of developmental events, including sta- men meristem specification, generation of sporogenous cells and their differentiation into microspore mother cells （MMCs）, meiosis, microspore （pollen） maturation, and polli- nation （Ma, 2005）. The formation of microspores and their development into mature pollen grains require cooperative interactions between gametophytic （microspores） and sporo- phytic （anther wall） cells, with the innermost cell layer, the tapetum, playing the most crucial role （Ma, 2005）. Tapetal cells underao decleneration bv Droclrammed cell death （PCD）.Dear Editor, Male reproductive development is an essential biological process for flowering plants and crucial for crop seed produc- tion.
