| Abstract/Contents: | "Proplastids of both tapetal cells and microsporocytes were present early in anther development. Tapetal proplastids differentiated - probably into elaioplasts - at late microspore stage. The tapetal cytoplasm was completely resorbed by early tricellular pollen stage. Microspore proplastids differentiated into amyloplasts at early bicellular stage, and were present in both vegetative and generative cells. In the generative cell, the amyloplasts were ephemeral and apparently degenerated within autophagic vacuoles. Plastids were absent from sperm cells. Vegetative cell amyloplasts increased in number apparently by fission such that one amyloplast produced one amyloplast and one proplastid per division. Mature pollen grains were estimated to contain between 550 and 820 amyloplasts with only one starch granule per plastid." |
