Abstract

A series of Hordeum vulgare cultivars was irradiated by X-rays to induce mutations in endosperm. Many structural defects of endosperm were revealed in plants irradiated 8 DAF. Change of a cell cycle was especially frequent and this was visible in the form of clones of small or large cells in the aleurone layer. X-irradiation appeared as a successful tool in the study of development.

Fig. 1. Developmental mosaics of aleurone layer (surface views) in irradiated caryopses of barley: A – an aleurone layer expressing lighter and darker patches of cells with less or more protein, respectively (stained by bromophenol blue). Two clones of larger cells are marked by arrows; B – three cells (black dots) expressing changed cell cycles – a large cell is developed as omitting at least two cytokineses; two small cells are created after one additional cytokinesis, in excess when compared to normal aleurone cells; C – a mosaic of aleurone layer with two adjacent clones of large and small cells, marked by black lines; D – a large fragment of aleurone layer with increased frequency of mutated cell clones, some are marked by arrows. Pictures B, C and D are taken under a polarising microscope.
