01Narrative

Dalbergia cochinchinensis, the Thailand rosewood, Siamese rosewood, or tracwood, (: Phayung ; Vietnamese: Trắc (or Cẩm lai nam bộ); Khmer: ក្រញូង: Kranhung ; Lao: ກະຍູງ: Kayung ; Chinese: 酸枝木: Suān zhī mù ) is a species of legume in the family Fabaceae. It is a tree yielding valuable hardwood found in Cambodia, Laos, Thailand, and Vietnam.Asian Regional Workshop (Conservation and Sustainable Management of Trees, Vietnam) 1998 In 2022 its status was re-evaluated as Critically Endangered caused by illegal logging and smuggling. Conservationists project that the species could be extinct within 10 years (by 2026). Due to its pioneering characteristics, drought tolerance, and nitrogen-fixing ability, it shows potential for restoring degraded forests and deforested sites. Therefore, sustainable plantation of the tree can serve both goals of conservation and forest landscape restoration. University of Oxford published the transcriptomes of Dalbergia cochinchinensis and five other Dalbergia spp. It was found that D. cochinchinensis had fewer R genes than the co-occurring Dalbergia oliveri.

05DNA & barcoding11 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 cochinchinensis has left across the world's sequence archives.

06Genome at a glanceCCDB · GoaT · NCBI

The complete instruction manual Dalbergia cochinchinensis 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≈700 604 944 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.

09Environmental DNA9 detections

Where the DNA of Dalbergia cochinchinensis 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
