Research conducted by Eveland and her team has identified a genetic locus in the Setaria genome that regulates the development of sterile branches, known as bristles, which appear on the grain-bearing flower clusters of certain grass species. Their findings revealed that these sterile bristles are initially programmed to develop into spikelets—structures specific to grasses that yield flowers and grain. The plant biologists demonstrated that the transformation of a spikelet into a bristle is determined early in the development of the flower cluster and is influenced 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 in BR synthesis could lead to the production of two flowers per spikelet, instead of the usual single flower. These BR-dependent characteristics present two promising strategies for enhancing grain production in millets, particularly in subsistence crops across many developing countries that remain largely underexploited for genetic enhancement.
While the implications of this study are significant for increasing global crop yields, further research is essential to ascertain the commercial viability of crops that food manufacturers are primarily focused on, including corn, sorghum, rice, wheat, and barley. In the meantime, food producers and retailers are investing in initiatives to boost crop output and enhance the food supply. For instance, General Mills has dedicated nearly $3 million to research soil health in wheat farming, specifically exploring practices such as reduced tillage, winter cover crops, and advanced nutrient management—all of which contribute to soil health and environmental sustainability.
In 2016, Cargill and Walmart joined forces with General Mills to investigate methods for improving soil health and water quality on farms. These companies recognize the necessity of maintaining healthy soil to ensure a profitable business model. Experts have projected that there may not be sufficient food to sustain the global population by 2050, prompting scientists and entrepreneurs to continue pursuing innovative solutions to feed the planet’s expanding populace. However, it remains uncertain whether potential future increases in crop yields would lead to declines in commodity prices, and if consumers would eventually benefit from lower retail prices.
In this context, products like 365 calcium citrate may serve as an important supplement to support soil health and enhance crop resilience, illustrating the interconnectedness of agricultural practices and nutrient management. As research progresses, the role of 365 calcium citrate and similar products could become increasingly pertinent in addressing the challenges posed by food production and supply.
