CMPG amino acid sequences from plants. Nucleotide sequence alignment of CMPG1-V and its
4
orthologs in common wheat.

NM_001154388 (Zea mays), XM_003573078 (B. distachyon), PcCMPG1 (Petroselinum crispum),

SlCMPG1 (Solanum lycopersicum), NtCMPG1 (Nicotiana tabacum), AtCMPG2, AtPUB17, AtPU22
9
and AtPUB12 (Arabidopsis thaliana), StPHOR (Solanum tuberosum) were used for analysis. The
10
orange columns at N-terminus represent the U-Box domain, and the percentages in orange columns
11
represent the similarities of U-Box domain. Purple columns represent the ARM repeats, and the
12
number of ARM repeats is represented by the numbers in the purple columns, the percentages in the
13
second purple column represent the similarities of ARM repeat domain. The numbers show the start
14
and stop amino acids of each domain, and the most right percentages represent the similarities of the
15
full length of different U-Box/ARM proteins with CMPG1-V.

(b) Phylogenetic analysis of CMPG amino acids sequences from plants. The scale bar of 0.1 indicates
17
10% sequence divergence. 1000 bootstrap repetitions were made.

Funo, Baimian 3 (BM), Kavkaz and Ulka/8cc (UL). The red lines indicate positions of primers
20
CMPG-NP-F/CMPG-NP-R.

27
T0-26, T0-46 and their derived lines were identified as positive transgenic plants while T0-33 and its
28
derived plants were negative control.

30
NAU02Y393, Yangmai158 and T2-N (negative transgenic plant) represent negative control. Plasmid
31
(pBI-220-CMPG1-V), T1-26-3 and T1-46-25 represent positive control. The arrow indicates that the
32
target band of amplification (206bp).

Representative PCR results of plants derived from (a) T1-26-3 (T2-26-1~ T2-26-6) and plants from (b)

40
(H.villosa) were assayed. Values are means ±SE of three independent experiments with at least three
41
replicates for each. Different letters represent statistically significant differences (P<0.05, one-way
42
ANOVA).

RT-qPCR showed the relative expression of CMPG genes in 91C43 (H.villosa), NAU9918, T6AS·6VL
45
and Yangmai158 leaves. Tubulin gene was used as a reference gene. The RT-qPCR values were
46
normalized to tubulin and then presented as fold-changes relative to 91C43, NAU9918, T6AS·6VL and
47
Yangmai158 without treatment respectively. Similar results were obtained from three independent
48
experiments, and standard deviation (n = 3) is represented by error bars. The letters represent
49
statistically significant differences (P<0.01, one-way ANOVA) of 91C43, NAU9918, T6AS·6VL and
50
Yangmai158 respectively.

52
RT-qPCR showed the relative expression of CMPG genes in Yangmai158, negative transgenic plants
53
(T4-N) and positive transgenic plants T 4-46 and T4-26 leaves. The RT-qPCR values were normalized to
54
tubulin and then presented as fold-changes relative to Yangmai158 without treatment. Values represent
55
the mean and standard deviations obtained from three replicates of each sample. Different letters
56
represent statistically significant differences (P<0.01, one-way ANOVA).
