Arachis pintoi, the Pinto peanut, is a forage plant native to Cerrado vegetation in Brazil. It is native to the valleys of the upper São Francisco and the Jequitinhonha rivers of Minas Gerais. It has been named after the Brazilian botanist Geraldo Pinto, who first collected the plant at the locality of Boca do Córrego, município de Belmonte (State of Bahia) in 1954 and suggested its potential as a forage. The species has been first described by A. Krapovickas and W. Gregory in 1994. This wild perennial relative of the groundnut or peanut, has been of increasing importance to pasture improvement in the tropics. Its stoloniferous growth habit, subterranean seed production, high forage quality, and acceptability to grazing cattle are of particular value. It is widely used in tropical grazing systems for ruminant livestock.Heuzé V., Tran G., Delagarde R., Bastianelli D., Lebas F., 2017. Pinto peanut (Arachis pintoi). Feedipedia, a programme by INRA, CIRAD, AFZ and FAO. https://www.feedipedia.org/node/702 Last updated on June 26, 2017, 15:11 The most common cultivar was first released in 1989 as cv. 'Amarillo' in Australia. Subsequently, it was released as cv. 'Mani Forrajero Perenne' in Colombia in 1992. It has been widely distributed in the tropics as accession CIAT 17434. The symmetry of the flower is zygomorph.

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 Arachis pintoi has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Arachis pintoi 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
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.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Wildobservation + sensor
Human sightings and records, or camera-trap / sensor detections — someone (or a device) saw or captured the species in the wild.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Arachis pintoi 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.
Signal
Where its DNA was found
How strong is each trace?
Modelled climatemodelled
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.
