Soy bean

- derived from wild soya, a species native to China, Japan, and Korea - first cultivated 3,000 years ago - the seeds are very high in protein (35 to 40%) - most economically important of the legumes - requires warm temps and a long growing season - used as fresh and dried beans, bean sprouts, edile oil products various asian cooking products like soy sauce and used as meat alternatives

Carob

- is a subtropical tree native to the arabian peninsula - the large pods, known as st.johns bread, contain seeds rich in protein an sugar - the pods are often sold fresh for the edile sweetmeat that surronds the seeds - another tropical leguminous tree, the tamarind is used in the same way - the pods can be processed into a thick paste used as a chocolate substitue - a gum is extracted from the seeds and is used as stabilizers and a thickener in ice creams, salad dressings and other food products - the most important are gum arabic and rhe guargum bean

Pea

- is an acient legume crop and has been cultivated for 7000 years - indigenous to the mediterranean region, the middle east and northern Africa - the seeds may be dried or eaten fresh - peas were an important source of protein in medieval Europe "mushy peas"

Nitrogen fixing bacteria

- legumes produce root nodules that house colonies on nitrogen fixing bacteria - these bacteria convert inert atmospheric nitrogen into a form that can be utilized by plants - because nitrogen is a limiting nutrient in most soils, the presence of these are a great assest and lugume are planted between years to increase the nitrogen in the soil

Common or kidney bean

- native to central and south america - the whole pod may be eaten fresh or the seeds may be harvested and dried - dried beans contain about 20% protein

- the fruit is know as legumes,single chambered pod with the seeds attached along one edge - dried seeds are very high in protein (up to 30%) - the seeds can be eaten fresh or dried for storage

ecological mutalism

- the legume provides food in the form of sugar from photosynthesis to the bacterial colonies in the nodules and recessive an essential nutrient for plant growth in return - the plant and the bacteria benefit from the association

Pea family
