E. Jonesvilleneuve et al., ASSESSMENT OF MICROINJECTION FOR INTRODUCING DNA INTO UNINUCLEAR MICROSPORES OF RAPESEED, Plant cell, tissue and organ culture, 40(1), 1995, pp. 97-100
Approximately 2,000 embryogenic uninuclear microspores of rapeseed (Br
assica napus) cv. Topas were intranuclearly injected with a chimaeric
beta-glucuronidase (Escherichia coli Uid A) gene. Stable integration h
ad not occurred among 55 plants that were regenerated. Coinjection of
the dye Lucifer Yellow and detection of injected DNA by the polymerase
chain reaction revealed high frequencies of transfer. However, the am
ount of DNA injected was less than 20 copies, which may have been insu
fficient for stable transformation of microspores.
