From: Aberrant imprinting may underlie evolution of parthenogenesis
The imprinted PHEL1 is upregulated in maternal, female gametophytic, and sporophytic tissues of apomictic Boechera, correlating with deregulation of DNA methyltransferase genes. (a) Maternal and paternal PHEL1 transcripts assayed by allele-specific RT-PCR in immature seeds, embryo, and endosperm fractions upon reciprocal crosses between two sexual Boechera accessions. (b–d) Relative transcript levels of PHEL1, MET1, and DRM2. Expression deviation from sexual Boechera (t-test significance levels: **α ≤ 0.01;*α ≤ 0.05).
