“…Additionally, there are other morphological traits modified during domestication, such as seed or plant tissue composition that are far less studied, especially in legumes. Different accumulation of nutrients, such as microelements, was recently shown in comparative analysis of wild and cultivated Phaseolus species (Schier et al, 2019). A recent study showed decrease carotenoids in crops compared with respective progenitors (Fernández‐Marín et al, 2014).…”

Legumes represent the second most important family of crop plants after grasses, accounting for approximately 27% of the world's crop production. Past domestication processes resulted in a high degree of relatedness between modern varieties of crops, leading to a narrower genetic base of cultivated germplasm prone to pests and diseases. Crop wild relatives (CWRs) harbor genetic diversity tested by natural selection in a range of environments. To fully understand and exploit local adaptation in CWR, studies in geographical centers of origin combining ecology, physiology, and genetics are needed. With the advent of modern genomics and computation, combined with systematic phenotyping, it is feasible to revisit wild accessions and landraces and prioritize their use for breeding, providing sources of disease resistances; tolerances of drought, heat, frost, and salinity abiotic stresses; nutrient densities across major and minor elements; and food quality traits. Establishment of hybrid populations with CWRs gives breeders a considerable benefit of a prebreeding tool for identifying and harnessing wild alleles and provides extremely valuable long-term resources. There is a need of further collecting and both ex situ and in situ conservation of CWR diversity of these taxa in the face of habitat loss and degradation and climate change. In this review, we focus on three legume crops domesticated in the Fertile Crescent, pea, chickpea, and lentil, and summarize the current state and potential of their respective CWR taxa for crop improvement.

“…Of course, many annual staple crops are also nutritionally important and constitute an essential part of gastronomic cultures. Moreover, specific annual crops may be more nutritionally dense than their perennial counterparts in some cases, as documented in one study of micronutrients of annual and perennial Phaseolus species (Schier et al, 2019). We do not advocate for the outright replacement of annual crops, but rather, for a reemphasis on perennial staple crops in those geographic and cultural contexts where exotic annual staple crops have been privileged by development agencies and colonial sensibilities over culturally established, Indigenous, perennial staple crops (Brandt et al, 1997;Chifamba, 2011;Rogé et al, 2016).…”

“…Efforts to this end are actively taking place through breeding projects to either perennialize herbaceous annual staple crops, or domesticate wild perennial grasses for food production (e.g., Kernza-Thinopyrum intermedium [Host] Barkworth & D.R.Dewey, a domesticated version of a wild perennial wheatgrass; Glover et al, 2012). For these breeding projects, and for a few shorter-lived perennial staple crops that have congeneric annual crops (such as beans), agronomic and environmental outcomes can be directly compared to the equivalent annual species (Vico and Brunsell, 2018;Schier et al, 2019). But scientific analyses on a global food system scale are lacking for already existing and nutritionally important perennial staple crops.…”

Staple crops, which have large amounts of carbohydrates, proteins, and/or fats, provide the bulk of calories in people's diets. Perennial plants, which can be productive for many years without the need for replanting, can produce staple foods and environmental benefits, but their agronomic and nutritional properties haven't been considered synthetically in comparison to annual staples. Here we offer a framework to classify perennial staple crops according to their nutritional categories and cultivation status. We assemble literature to report on the yield potential of 51 perennial staple crops, only 15 of which are well-characterized in existing global datasets. We show the extent and distribution of perennial staple crop production in relation to annual crop types, calculate the carbon stocks they hold, and analyze their nutritional content for three macronutrients and nine micronutrients. We found that most perennial staple crops are regional crops (not globally traded) that grow in the subtropics to tropics. At least one perennial staple crop in each of the five nutritional categories has yields over 2.5 t/ha, in some cases considerably higher, competitive with and in many cases exceeding those of nutritionally comparable annual staples. Perennial staple crops only comprise ~4.5% of total cropland. They hold a modest ~11.4 GtC above and below ground, less than one third of the anthropogenic carbon-equivalent emissions for the year 2018, but more than the ~9 GtC held by the same amount of annual cropland. If linear growth in land under perennial staple production continues to 2040, and replaces only annual cropland, an additional ~0.95 GtC could be sequestered. Many perennial crops also had competitive macronutrient density and yield (per unit area) compared to annual staples; moreover, specific perennial staples are abundant in specific micronutrients, indicating that they can be a nutrient-dense part of diets, unlike the most ubiquitous annual staple crops (corn, wheat, rice) that do not appear in the top 85th percentile for any of the nine micronutrients analyzed. Transition of land and diets to perennial staple crops, if judiciously managed, can provide win-win solutions for both food production and ecosystems.

“…Although the use of inorganic fertilizers is a cost-effective, simple, and quick method of agronomic biofortification, it has several drawbacks. The main downside is related to the misuse of inorganic fertilizers, which has negative environmental consequences such as water pollution, algal bloom, and biodiversity loss in various natural systems (Zhang et al, 2019;Schier et al, 2019;Jewell et al, 2020). Moreover, these are expensive, if considered for bulk application to soil, and labor-intensive to apply, which may further impoverish farmers with small holdings.…”

Agronomic biofortification of food crops: An emerging opportunity for global food and nutritional security

Fortification of food with mineral micronutrients and micronutrient supplementation occupied the center stage during the two-year-long Corona Pandemic, highlighting the urgent need to focus on micronutrition. Focus has also been intensified on the biofortification (natural assimilation) of mineral micronutrients into food crops using various techniques like agronomic, genetic, or transgenic. Agronomic biofortification is a time-tested method and has been found useful in the fortification of several nutrients in several crops, yet the nutrient use and uptake efficiency of crops has been noted to vary due to different growing conditions like soil type, crop management, fertilizer type, etc. Agronomic biofortification can be an important tool in achieving nutritional security and its importance has recently increased because of climate change related issues, and pandemics such as COVID-19. The introduction of high specialty fertilizers like nano-fertilizers, chelated fertilizers, and water-soluble fertilizers that have high nutrient uptake efficiency and better nutrient translocation to the consumable parts of a crop plant has further improved the effectiveness of agronomic biofortification. Several new agronomic biofortification techniques like nutripriming, foliar application, soilless activation, and mechanized application techniques have further increased the relevance of agronomic biofortification. These new technological advances, along with an increased realization of mineral micronutrient nutrition have reinforced the relevance of agronomic biofortification for global food and nutritional security. The review highlights the advances made in the field of agronomic biofortification via the improved new fertilizer forms, and the emerging techniques that achieve better micronutrient use efficiency of crop plants.
