Phylogenetic Tree of 704 Indole-3-Acetic Acid Methyltransferase Sequences

704 IAMT protein sequences were aligned to construct a maximum likelihood phylogenetic tree. The analysis used the JTT+R8 substitution model and 1000 ultrafast bootstrap replicates for branch support. The dataset, created by Bahar Saadaie Jahromi, represents a curated collection of sequences from NCBI and OneKP databases.

Use Cases

• Analyze the evolutionary relationships among the 704 IAMT sequences using the phylogenetic tree structure.
• Validate the JTT+R8 amino acid substitution model's performance on IAMT protein family data.
• Assess branch support values derived from 1000 ultrafast bootstrap replicates for phylogenetic confidence.
• Cross-reference IAMT sequences sourced from NCBI's nr and tsa-nr databases with those from the OneKP database.

Strengths

• Contains 704 distinct IAMT protein sequences for analysis.
• Phylogenetic tree was estimated with a specific, optimized substitution model (JTT+R8).
• Branch support is quantified using 1000 ultrafast bootstrap replicates.
• Sequences were sourced from multiple authoritative databases including NCBI and OneKP.

Limitations

• The dataset is very small in size (75.1 KB), limiting its scope to sequence and tree data only.
• No raw sequence alignment files or columnar data are provided, only the final phylogenetic tree description.
• The temporal and geographic origins of the source sequences are not specified.

Provenance

Source

NCBI non-redundant protein (nr), Transcriptome Shotgun Assembly (tsa-nr), Core-nt, wgs, TSA databases, and the OneKP database of China National Gene Bank.

Collection Method

Sequences obtained via BlastP and TBlastN searches using Arabidopsis thaliana IAMT (NP_200336.1) as query, aligned with MAFFT, with phylogeny estimated by IQtree.
