HTA3:GFP expression in wild-type and dme-2 mutant central cells.Confocal image of WT (a) and dme-2 mutant (b) developing ovules expressing an HTA.3:GFP transgene. Expression is confined to the central cell. (c) Box plot showing the distribution of GFP positive central cells between WT and dme-2 mutant ovules. There was no significant change in GFP positive central cells in DME/dme-2. + mark in boxplot is mean of data. The line in a box is median (n = 554 mature ovules for HTA3:GFP/- plants and 412 mature ovules for HTA3:GFP/- in DME/dme-2 heterozygous plants. The values are not significantly different by Student’s t test
