Y. Kishima et al., PHYSICAL MAPPING OF DIFFERENCES BETWEEN THE CHLOROPLAST DNAS OF BETA-VULGARIS AND B-WEBBIANA, Plant breeding, 114(4), 1995, pp. 361-362
A physical map of Beta webbiana (a wild species of the section Procumb
entes) chloroplast genome was constructed by localizing the cleavage s
ites of SmaI, PstI, PvuII, XhoI, and HindIII, and the map was then ali
gned with the map of sugarbeet (B. vulgaris) chloroplast DNA. This ali
gnment shows 27 restriction-site changes and 11 insertions/deletions,
most of which occur in the large single-copy region of the genome. A 0
.7-kb long mutation,located within an unidentified open reading frame
(ORF2280) in the inverted repeat, was also found.
