Other claims from this paper (18)
- Observation Agropyron chloroplast genome length ranged from 135,321 to 135,564 bp.
- Observation Agropyron chloroplast GC content was stable at 38%.
- Observation All Agropyron chloroplast genomes encoded 132 consistent genes.
- Observation Direct repeats predominated among long repeats, numbering 29-31.
- Observation Each Agropyron sample contained 29-34 tandem repeats.
- Observation Agropyron mongolicum Keng (0506) had the maximum 34 tandem repeats.
- Observation Most samples had 13 palindromic long repeats.
- Observation Most samples had 29-31 forward long repeats.
- Observation No reverse or complementary repeats were detected.
- Observation Codon endings were predominantly A/U, accounting for 48.4% of RSCU > 1 codons.
- Observation Nucleotide diversity analysis found six hypervariable regions including psbA and rpl32.
- Method / resource Those hypervariable regions did not distinguish the five Agropyron species.
- Observation Agropyron samples formed a strongly supported monophyletic clade with bootstrap 100.
- Observation Relationships among five species and two varieties remained unresolved, with 178 informative sites out of 135,978.
- Observation No species-specific chloroplast SNPs or indels were found.
- Method / resource PCA did not separate species on the first two principal components.
- Method / resource STRUCTURE analysis of Angiosperms353 markers favored K = 2 groups.
- Observation STRUCTURE genetic grouping did not match Agropyron taxonomy.
