01Narrative

Exacum travancoricum is one of the rare and threatened plants of western Ghats. It comes under family Gentianaceae. Moderately to much branched usually laxly cushion-like herb with elliptic, somewhat succulent leaves and usually solitary terminal pale blue to blue flowers. Endemic to Southern Western Ghats at 950-1800m (Ponmudi, Agasthyamala and Tinnevelly hills). Flowers during July - November.Greeting Cards, Tropical Botanic Garden & Research Institute, Pacha, Palode, Trivandrum - 695 562. 1997 Leaves dense, fleshy, 1-1.5 x 0.6-0.8 cm, elliptic-ovate, obtuse to round at apex, attenuate at base; margins thin; midrib prominent.Exacum travancoricum Bedd., Ic. t. 118. 1868-1874; Gamble, Fl.

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 Exacum travancoricum has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Exacum travancoricum 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.

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.
