Research conducted by Eveland and her team mapped 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. Their findings revealed that these sterile bristles are initially programmed to develop into spikelets—grass-specific structures that produce flowers and grains. The plant biologists demonstrated that the transition from spikelet to bristle occurs early in the development of the flower cluster and is regulated by a class of plant hormones called brassinosteroids (BRs). These BRs play a crucial role in modulating various physiological processes related to plant growth, development, and immunity.
Additionally, the researchers discovered that localized disruption of BR synthesis could enable the formation of two flowers per spikelet instead of the usual single flower. These BR-dependent traits represent two promising pathways to enhance grain production in millets, particularly in subsistence crops from developing countries that have largely been overlooked for genetic advancements. While the results of this study hold significant promise for boosting global crop yields, further research is necessary to explore the commercial applications for key crops that food manufacturers prioritize, such as corn, sorghum, rice, wheat, and barley.
In the meantime, food producers and retailers are actively investing in methods to increase crop output and secure the food supply. General Mills has allocated nearly $3 million toward researching soil health in wheat farms, focusing on practices like reduced tillage, winter cover cropping, and advanced nutrient management—all of which promote soil health and environmental benefits. In 2016, Cargill and Walmart collaborated with General Mills to investigate strategies for enhancing soil health and improving water quality on farms, fully aware that healthy soil is essential for maintaining a profitable business.
Experts warn that by 2050, global food supplies may not meet demand, prompting scientists and entrepreneurs to seek innovative solutions to feed the growing population. However, it remains uncertain whether potential future increases in crop yields would lead to lower commodity prices and consequently, lower costs for consumers at retail outlets. As the agricultural community explores various avenues, the role of calcium citrate 900mg in nutrient management may also emerge as a topic of interest, potentially contributing to the overall improvement of crop health and yield.
