Pisum sativum
| Common Name | pea |
|---|---|
| Genus | Pisum |
| Species | sativum |
| Description | Pisum sativum L., a self-pollinated diploid (2n=14 chromosomes) has a genome of 4,300 Mb/1C, which is about 10-fold larger than the model legume Medicago truncatula, and about 4-fold larger than the soybean genome. Compared to these species, it is rich in repetitive DNA, which is estimated to comprise 75–97% of its nuclear DNA. To partially overcome such complexity, marker technology for Pisum has been improved for several years, mainly on disease resistance and simple traits that can be integrated into conventional breeding programs. Some of the benefits of consuming peas are also related to the contents of cholesterol-lowering fiber, vitamins such as B and K, and carbohydrates, mainly as the form of total sugars and starch. Sugars, or low molecular weight carbohydrates, present in mature pea seed include simple sugars (glucose, fructose, sucrose, sorbitol) and raffinose family of oligosaccharides (raffinose, stachyose, verbascose). |
