Vicia faba is a stiffly erect, annual plant 0.5 to 1.8 metres (1 + 1 ⁄ 2 to 6 ft) tall, with two to four stems that are square in cross-section. The leaves are 10 to 25 centimetres (4 to 10 in) long, pinnate with 2–7 leaflets, and glaucous (grey-green). Unlike most other vetches, the leaves do not have tendrils for climbing over other ...
Vicia is a genus of over 240 species of flowering plants that are part of the legume family , and which are commonly known as vetches. Member species are native to Europe, North America, South America, Asia and Africa.
The flowers are arranged in pairs (although sometimes solitary) on long (5 cm) peduncles branching from the leaf axils. The petals are purple and white, 2 cm long, and have 10 stamens and 1 style. The fruit is a hairy pod or legume up to 5 cm long with 4 to 8 seeds. [2] It has 14 chromosomes. [2] [4]
Uromyces viciae-fabae var. viciae-fabae is a plant pathogen commonly known as faba-bean rust. The rust is distinguished by the typical rust-like marks on the stem and leaves, causing defoliation and loss of photosynthetic surface along with reduction in yield. The disease is fungal and is autoecious meaning it has one plant host.
All of the flowers in an inflorescence open at once. In the Faboideae, the flowers are zygomorphic, and have a specialized structure. The upper petal, called the banner or standard, is large and envelops the rest of the petals in bud, often reflexing when the flower blooms. The two adjacent petals, the wings, surround the two bottom petals.
Botrytis fabae is a plant pathogen, a fungus that causes chocolate spot disease of broad or fava bean plants, Vicia faba. It was described scientifically by Mexican-born Galician microbiologist Juan Rodríguez Sardiña in 1929. [1]

Vicine was initially isolated in 1870 from the seeds of Vicia sativa by a method of extraction with sulfuric acid and subsequent precipitation with mercury sulfate (HgSO 4). Later vicine was also found in other Vicia species, namely Vicia faba, beet juice and peas. The chemical structure of the compound was built gradually.
