01Narrative

Dendrobium discolor, commonly known as antler orchids, are epiphytic or lithophytic orchids in the family Orchidaceae. They have cylindrical pseudobulbs, each with between ten and thirty five leathery leaves, and flowering stems with up to forty mostly brownish or greenish flowers with wavy and twisted sepals and petals. Antler orchids occur in northern Australia, New Guinea and Indonesia and there are several subspecies and varieties.

05DNA & barcodingmolecular

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 Dendrobium discolor has left across the world's sequence archives.

06Genome at a glanceCCDB · GoaT

The complete instruction manual Dendrobium discolor 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 size880 200 000 bp

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.
