Summary: | Buckwheat is a nutritional and economically crop belonging to
Polygonaceae
,
Fagopyrum
. To better understand the mutation patterns and evolution trend in the chloroplast (cp) genome of buckwheat, and found sufficient number of variable regions to explore the phylogenetic relationships of this genus, two complete cp genomes of buckwheat including
Fagopyrum dibotry
s (
F
.
dibotrys
) and
Fagopyrum luojishanense
(
F
.
luojishanense
) were sequenced, and other two
Fagopyrum
cp genomes were used for comparative analysis. After morphological analysis, the main difference among these buckwheat were height, leaf shape, seeds and flower type.
F
.
luojishanense
was distinguishable from the cultivated species easily. Although the
F
.
dibotrys
and two cultivated species has some similarity, they different in habit and component contents. The cp genome of
F
.
dibotrys
was 159,320 bp while the
F
.
luojishanense
was 159,265 bp. 48 and 61 SSRs were found in
F
.
dibotrys
and
F
.
luojishanense
respectively. Meanwhile, 10 highly variable regions among these buckwheat species were located precisely. The phylogenetic relationships among four
Fagopyrum
species based on complete cp genomes was showed. The results suggested that
F
.
dibotrys
is more closely related to
Fagopyrum tataricum
. These data provided valuable genetic information for
Fagopyrum
species identification, taxonomy, phylogenetic study and molecular breeding. |
