- Abstract
Microsporogenesis in Lilium longiflorum Thunb. is a naturally synchronous process and affords a system in which to study stage-specific events of meiosis and anther development. Zymogram gel analyses were conducted with extracts from a variety of stages of anther development to identify proteinases which likely play roles in anther metabolism. These experiments revealed that several proteinases are present at different stages of anther development, and class-specific inhibitors were used to classify these enzymes. Proteolytic activities increased as anther development proceeded and these activities were temporally correlated with the apoptotic events which precede dehiscence, as well as with events crucial for the maturation of viable pollen.
