Extended Data Fig. 2: F-actin and MT aster structures become more apparent after the 3rd nuclear divisions.

a, Illustration showing how to set the axis for analyzing frequency histograms of spatial orientations of F-actin and MTs surrounding the endosperm nucleus (related to Figs. 2c−e and 4a−c) and definition of the criteria to evaluate aster structure. Magenta, nucleus; cyan, F-actin or MTs. b,c, Probability distribution of F-actin (b) and MTs (c) in degrees relative to the axis of a quarter nucleus (bottom in a). The probability is calculated from all frequency histograms of the orientations of F-actin and MTs combined from the entire nucleus (top in a). Different colors denote the different nuclear division stages. The shaded area indicates reticulate patterns of F-actin and MTs, which do not contribute to the aster structures.
