Remarkably, seeds such as soybeans containing very high levels of protein can undergo desiccation, yet survive and revive after water absorption. Carl Leopold, son of Aldo Leopold, began studying this capability at the Boyce Thompson Institute for Plant Research at Cornell University in the mid-1980s.He found soybeans and corn to have a range of soluble carbohydrates protecting the seed's cell viability.
The scar, visible on the seed coat, is called the hilum (colors include black, brown, buff, gray and yellow) and at one end of the hilum is the micropyle, or small opening in the seed coat which can allow the absorption of water for sprouting.
Fermented soy foods include soy sauce, fermented bean paste, natto and tempeh. The first photosynthetic structures, the cotyledons, develop from the hypocotyl, the first plant structure to emerge from the soil.
The main countries growing soybeans are the United States (32% of world total, 2016 forecast), Brazil (31%) and Argentina (18%). These cotyledons both act as leaves and as a source of nutrients for the immature plant, providing the seedling nutrition for its first 7 to 10 days.
For example, soybean products, such as textured vegetable protein (TVP), are ingredients in many meat and dairy substitutes. Glycine soja is the wild ancestor of Glycine max, and grows wild in China, Japan, Korea and Russia.
The beans contain significant amounts of phytic acid, dietary minerals and B vitamins. includes the cultivated soybean, Glycine max (L.) Merr., and the wild soybean, Glycine soja Sieb. Like most plants, soybeans grow in distinct morphological stages as they develop from seeds into fully mature plants.
