One of its components is a (*) tube nucleus that produces a tube down the style, while another of its components is a generative cell that undergoes mitosis to produce two cells, one of which fuses with the diploid endosperm.
Cysteine rich polypeptides called LUREs act as a chemoattractant that guides one of its components. Media used for culturing it require elevated levels of boron. The tapetum is the nutritive layer that supports its development, and it is classified as colpate or sulcate depending on the orientation of furrows. One of its components is a (*) tube nucleus that produces a tube down the style, while another of its components is a generative cell that undergoes mitosis to produce two cells, one of which fuses with the diploid endosperm.
