Description

María Núñez and six colleagues made new analogs of brassinosteroids, the plant hormones that steer growth. The new compounds carry a benzoate group at a key carbon, decorated with added groups of differing size and electronegativity. Activity was tested two ways: bending of rice leaf segments, a classic hormone assay, and root growth inhibition in Arabidopsis. Buildup of a signaling protein measured pathway activation inside cells.

Set against earlier series, the tests isolated the effect of one ring's chemistry. A two-hydroxy setup beat carbonyl or single-hydroxy variants. Docking math linked binding strength to the measured responses. The team could thus follow structure from first binding, through a signaling step, to whole plant response. Such maps help design growth regulators that work at lower doses in agriculture.
