A team of researchers at the University of California, Riverside, has accomplished success in microbial production of a class of plant hormones, known as strigolactones. According to the preceding studies and pieces of research, strigolactones along with several hormones are synthesized within the plants, which can help regulate the growth and development of flora. The scientists mentioned that owing to the ability of strigolactones to develop symbiotic relationships with microorganisms, several agronomists and soil scientists have been showing keen interest in these kinds of hormones. This relationship remarkably improves the crop yield as the plantscan efficiently absorb nutrients directly from the soil, thereby boosting the nutrient uptake of the soil.

Yarn Li, who is an Assistant Professor with a specialization in environmental & chemical engineering, demonstrated countless benefits of these compounds in the agricultural sector. Despite multiple advantages, no pragmatic approach has been discovered yet to efficiently synthesize and extract strigolactones. He also mentioned that the research is still ongoing as this group of plant hormones promotes germination as well as the rapid vegetative growth of plants.

Strigolactones production from yeast is a complicated and laborious process. The scientists have been engaged in the research comprising utilization of plant genes and baker’s yeast for the last 3 years. After multiple attempts, they succeeded in synthesizing strigolactones by converting a precursor hormone known as carlactone under in vitro conditions.However, the precursor hormonewas unstable, which made the process of strigolactones synthesis impractical as E. coli failed to further modify the genes.

To enhance the stability of the hormone, Kang Zhou, the co-author of the study published in an open-access journal Science Advances,devised an innovative technique known as the microbial consortium technique. In this approach, both bacteria and yeast were cultured in the same medium. The precursor hormone synthesized by E. coli was instantly modified by yeast into strigolactones. This sophisticated research would eventually lay the foundation to enhance the crop yield, thereby mitigating the concern of global food scarcity.
