Heterokaryon identification through simultaneous fluorescence of tetramethylrhodamine isothiocyanate and fluorescein isothiocyanate labelled protoplasts. 1984

T L Barsby, and S A Yarrow, and J F Shepard

Protoplasts were separately stained with the fluorescent dyes fluorescein isothiocyanate (FITC) and tetramethylrhodamine isothiocyanate (TRITC). Following fusion, doubly stained heterokaryons were identified under fluorescence microscopy by using the Zeiss filter set 48 77 05 (excitation filter 450-490 nm, dichroic reflector 510 nm, and barrier filter 520 nm) which allowed simultaneous fluorochrome emissions. Previously, either emission spectrum, but not both, was possible for any single filter set.

UI	MeSH Term	Description	Entries
D010944	Plants	Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE.	Plant
D011523	Protoplasts	The protoplasm and plasma membrane of plant, fungal, bacterial or archaeon cells without the CELL WALL.	Protoplast
D002459	Cell Fusion	Fusion of somatic cells in vitro or in vivo, which results in somatic cell hybridization.	Cell Fusions,Fusion, Cell,Fusions, Cell
D005456	Fluorescent Dyes	Chemicals that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags.
