01Narrative

Dalbergia oliveriGamble JS ex Prain D (1897) J. Asiat. Soc. Bengal, Pt. 2, Nat. Hist. 66: 451. is a species of legume in the family Fabaceae which grows in tree form to 15 – 30 meters in height (up to 100 ft.). The fruit is a green pod containing one to two seeds which turn brown to black when ripe. It is threatened by habitat loss and over-harvesting for its valuable red "rosewood" timber. University of Oxford published the transcriptomes of Dalbergia oliveri and five other Dalbergia spp. It was found that D. oliveri had more R genes than the co-occurring Dalbergia cochinchinensis.

05DNA & barcoding21 specimens

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Dalbergia oliveri has left across the world's sequence archives.

06Genome at a glanceCCDB · GoaT · NCBI

The complete instruction manual Dalbergia oliveri carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.

Genome sizehow big the whole instruction manual is

Genome size≈689 201 487 bp assembly estimate

Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).

Chromosomes & ploidyhow the DNA is packaged

2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants. Click any value below to see the underlying records and sources.

Sequencing statusassembly quality — how far to trust these numbers

Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.

Where the DNA of Dalbergia oliveri was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
