Nature-Inspired Biphenyls and Diphenyl Ethers: Design, Synthesis, and Biological Evaluation

mycolabadmin

Researchers synthesized compounds inspired by naturally occurring substances found in brown algae called phlorotannins. These synthetic compounds were tested against fungi that damage rice crops and other plants. Some methylated versions showed promise in slowing fungal growth, suggesting they could potentially be developed into new natural fungicides. However, the compounds were not effective against bacteria, indicating more research is needed.

Abscisic Acid Metabolizing Rhodococcus sp. Counteracts Phytopathogenic Effects of Abscisic Acid Producing Botrytis sp. on Sunflower Seedlings

Scientists discovered that a beneficial soil bacterium can protect sunflower plants from a harmful fungus by eating the toxin the fungus produces. The fungus normally weakens plant defenses by producing a chemical called abscisic acid, but the bacterium metabolizes this chemical and prevents it from harming the plant. This approach works without the bacterium directly killing the fungus, offering a new way to protect crops from disease.

Abscisic Acid Metabolizing Rhodococcus sp. Counteracts Phytopathogenic Effects of Abscisic Acid Producing Botrytis sp. on Sunflower Seedlings

Researchers discovered that a beneficial soil bacterium (Rhodococcus sp.) can protect sunflower plants from a harmful fungus (Botrytis sp.) by breaking down a plant stress hormone (ABA) that the fungus produces to weaken plant defenses. Unlike other protection methods that kill the fungus or boost immune responses, this bacterium works by removing the fungus’s chemical weapon. This discovery suggests new ways to protect crops from diseases.
