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 flowering (DAF).

Methods: Adult zebrafish were put into a 10 micromol/L DiA water solution and then anaesthetized for observation under a fluorescent microscope.
Results: The labeled substance appeared in round bright spots and some of them gather together to form a cluster which distributed through the body surface orderly.
