摘要

An investigation was conducted to determine the effect of the mac1 mutation (multiple archesporial cells) on the development of ovules and anthers of Z. mays. Mac1 anthers did not form three normal layers, and the archesporial cells divided excessively and most of them failed to form microsporocytes. The centrally located mutant microsporocytes were abnormal in both appearance and callose distribution, and they failed to pass through meiosis. In mac1 mutant ovules several archesporial cells were formed instead of the single cell as typical for normal maize ovules. Some of the resulting megasporocytes undergo normal meiosis, and some degenerate. Each ovule displays a range of developmental stages of the sporogenous cells. The study suggests that the mac1 mutation plays an important role in disturbance of the control over switching meristematic cells from the vegetative to the meiotic (sporogenous) pathway, which causes abundance of archesporial cells in anthers and ovules.
