Abstract
The quality and yield of rice are characterized by starch. ADP-glucose pyrophosphorylase small subunit gene is one of the
key enzyme genes of starch synthesis. In this study, PCR amplification, cloning, sequencing and sequence alignment of Common wild
rice (from Yuanjiang),
japonica
(Yumi15),
indica
(93
-
11) and
indica
-
japonica
lines (Nan34) were analyzed by specific primer (seq-
uences of F: 5'
-
TACGCTATGCTCTTGAAAC

3'; R: 5'

-
3') to ADP-glucose pyrophosphorylase
small subunit gene (
AGPsma
). Besides, 20 accessions of wild rice of 15 AA and 5 CCDD genomes from 13 countries, and 205 rice
cultivars which covers 40
Indica
and 165
Japonica
including Yunnan landraces and improved lines were PCR detected by the primer.
The fragments of 184 bp and 215 bp in four different rice with the primer were sequences of
AGPsma
. The similarity between common
wild rice (from Yuanjiang) and Yumi15, between common wild rice and 93
-
11, and between common wild rice and Nan34 was 100%,
99.54%, and 85.19%, respectively. On 109 bp of the sequence, common wild rice from Yuanjiang and Yumi15 were T, but 93
-
11 and
Nan34 were C. In the range of 121~151 bp, indica-japonica lines Nan34 deleted 31 bases. The total rice accessions were divided into
three classes. The first class only has 215 bp fragment, including all the wild rice and 196
indica
and Japonica materials. The number
of
indica
accounted for 95% of the total
indica
samples, and
indica
landraces accounted for 75% of the total
indica
landraces; The
number of
Japonica
accounted for 83.6% of the total
Japonica
samples, and
Japonica
landraces accounted for 60% of the total
Japonica
landraces; The second class only has 184 bp fragment, including 28 and
Japonica
materials. The third class have 215 bp and 184 bp
