(a) A pool of 4 plants were analysed for each of the indicated genotypes and a total of 32 plants were used. (b) Each pool was co-analysed together with a 2n WT sample as an internal control. 2C, 4C and 8C refer to the copy numbers of chromosomes in the nuclei analyzed and they were assigned by comparing to a known diploid WT control.
