Hemp has become increasingly popular for its versatile uses — CBD-rich varieties are in high demand for pharmaceutical products, while fiber-rich varieties are valued for industrial applications like textiles. Now, a new University of Houston study of hemp microbes, published in the journal Nature, may help scientists create special mixtures of helpful microbes to make hemp plants produce more CBD or have better-quality fibers.
As a community of tiny organisms including microbes, the plant microbiome helps plants absorb nutrients, handle stress and produce valuable compounds.
The study, led by Abdul Latif Khan, assistant professor of biotechnology at the Cullen College of Engineering Technology Division, examined the communities of microbiomes living in and around the roots (rhizosphere) and on the leaves (phyllosphere) of four types of hemp plants. Khan’s team also compared how these microorganisms differ between hemp grown for fiber and hemp grown for CBD production.
“In hemp, the microbiome is important in terms of optimizing the production of CBD and enhancing the quality of fiber. This work explains how different genotypes of hemp harbor microbial communities to live inside and contribute to such processes,” reports Khan. “We showed how different types of hemp plants have their own special groups of tiny living microbes that help the plants grow and stay healthy.”
“Understanding these microorganisms can also lead to more sustainable farming methods, using nature to boost plant growth instead of relying heavily on chemicals,” said Waqar Ahmad, the paper’s first author and doctoral student of Khan’s.
