- ... 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 ...

- ... Transmission electron microscopy (TEM) and fluorescence microscopy studies revealed that the metaphloem sieve elements (MSEs) in the ventral vascular bundle of the caryopses of developing wheat (Triticum aestivum L.) undergo a unique type of programmed cell death (PCD). Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive nuclei were observed at 3 and 4 days after ...
