Autofluorescence of developing plant vegetative microspores studied by confocal microscopy and microspectrofluorimetry.

Phenomenon of autofluorescence from vegetative microspores of spore-breding plant Equisetum arvense has been studied by methods of laser-scanning confocal microscopy (LSCM) and microspectrofluorimetry during the development of the cells. The microspores have demonstrated a difference between structures: blue-fluorescing cover and red-fluorescing chloroplasts. The fluorescence spectra of the studied cells was also measured by original microspectrofluorimeter.
