Arachis rigonii
Arachis rigonii is a wild relative of the cultivated peanut.
Taxonomy and Nomenclature
- Scientific Name: Arachis rigonii Krapov. & W.C. Greg.
- Family: Leguminosae (Pea Family) / Faboideae (Subfamily)
- Kingdom: Plantae
- Rank: Species
- Synonyms:
- Arachis angustifolia (Chodat & Hassl.) Hoehne
- Arachis diogoi sensu Burkart (Misapplied Name)
Distribution and Habitat
- Endemic to Bolivia.
Conservation Status
- Listed as 'Critically Endangered' in the 'Red List Book of Crop Wild Relatives of Bolivia'.
Morphological Characteristics and Growth Habits
- The development of Arachis rigonii is erect.
- In the lower part, they have a pretty bare stem, with many ramifications.
Genetic Information
- The species has an Arachis rigonii nonexpressor of pathogenesis-related protein 1 (NPR1) gene (complete cds 2,303 bp linear DNA).
- It is a diploid species.
- Karyotypes have been studied in relation to other species within the genus Arachis.
Interactions with Other Organisms
- Used in interspecific hybrids with cultivated peanuts (Arachis hypogaea) to improve traits.
Quirky Facts
- Accessions of Arachis rigonii have been found to have a lower content of palmitic acid compared to other wild Arachis species.
- It has been used in crosses to improve peanut varieties and is a valuable source for genetic improvement.
