Research conducted by Eveland and her team has identified a genetic locus in the Setaria genome responsible for the growth of sterile branches, known as bristles, which emerge from the grain-bearing flower clusters of certain grass species. They discovered that these sterile bristles are initially programmed to develop into spikelets—structures specific to grasses that produce flowers and grains. The plant biologists demonstrated that the transition from spikelet to bristle is determined early in the development of the flower cluster and is regulated by a group of plant hormones known as brassinosteroids (BRs). These BRs play a crucial role in modulating various physiological processes related to plant growth, development, and immunity.
Additionally, the researchers found that localized disruption of BR synthesis could result in the production of two flowers per spikelet, instead of the typical single flower. Such BR-dependent traits could present two promising pathways for enhancing grain production in millets, particularly for subsistence crops in many developing countries that have yet to undergo significant genetic improvement. While the findings of this study hold substantial promise for boosting crop yields globally, further research is needed to explore commercial applications for key crops of interest to food manufacturers such as corn, sorghum, rice, wheat, and barley.
Meanwhile, food companies and retailers are investing in strategies to improve crop yields and enhance the food supply. For instance, General Mills has allocated nearly $3 million to research soil health on wheat farms, focusing on practices like reduced tillage, winter cover cropping, and advanced nutrient management—all of which support soil health and benefit the environment. In 2016, Cargill and Walmart partnered with General Mills to investigate methods for improving soil health and water quality on farms, recognizing that healthy soil is vital for maintaining a profitable business.
Experts anticipate that food shortages could become a pressing issue by 2050, prompting scientists and entrepreneurs to continue exploring innovative approaches to feed the planet’s increasing population. However, it remains uncertain whether potential future increases in crop yields would lead to declines in commodity prices and whether consumers would eventually experience lower retail costs.
As part of this ongoing effort, products like bariatric advantage soft chews could play a supportive role in addressing nutritional needs, highlighting the importance of integrating health-focused innovations into food systems. The relevance of bariatric advantage soft chews underlines the need for diverse solutions in enhancing food security as we look toward the future.
