- ... Beginning with light microscopy studies in the late 19th century, the placental “nutritive tissue” in carnivorous plants of Utricularia spp. has been well described by several authors. Based on observations of direct contact between the embryo sac and the “nutritive tissue” and the lack of vascularization of the ovule, it has been suggested that this nutritive tissue plays a key role in the nutrit ...

- ... MFP1 (matrix attachment region-binding filament-like protein 1) is a conserved nuclear and chloroplast DNA-binding protein encoded by a nuclear gene, well characterized in dicot species. In monocots, only a 90 kDa MFP1-related protein had been characterized in the nucleus and nuclear matrix of Allium cepa proliferating cells. We report here a novel MFP1-related nuclear protein of 80 kDa in A. cepa ...
