Interpretive Summary:

Technical Abstract: Structure, histochemistry and composition of mature seeds of several ancient or alternative crops were studied by light and electron microscopies to localize specific macronutrients including protein, starch, non-starch carbohydrates and lipid. Botanically, these seeds fall into different classifications, some of them are cereals (channel millet, eel grass, perennial grains), others are pseudo-cereals (amaranth, quinoa, buckwheat) which are typically dicotyledonous plants that are consumed like a cereal and yet others (desert ironwood, mesquite, Illinois bundle flower) are legumes. Many ancient crops have small seeds due to limited selective breeding. The benefit of a small seed is that all of the essential enzymes and nutrients necessary for plant growth are packaged into a small space. Thus, the seeds are more nutrient-dense and contain densely-packed proteins and lipids with little corresponding starch compared to their commercial, large-seeded counterparts. The nutrient dense and starch-poor seeds make ancient seeds excellent choices for human health. Another benefit of these ancient crops is that some of them are tolerant to agronomic conditions which are less than optimal for the cultivation of commercial crops. Here, we note the distribution and relative proportions of macronutrients in various seeds that, together, we term alternative or ancient crops.
