Rocketing labor cost is a major challenge threatening agricultural sustainability and food security worldwide. The replacement of manual pruning of horticultural plants with chemical pruning has long been a goal for saving cost and reducing virus spreading. Here, guided by the structure-function relationship of allelochemical benzoic acid derivatives, we have identified 4-(2-phenylethynyl)-benzoicacid (PEBA) as a highly bioactive compound.

Allelochemicals are specific secondary metabolites that can exhibit autotoxicity by inhibiting the growth of the same plant species that produced them. These metabolites have been found to affect various physical processes during plant growth and development, including inhibition of seed germination, photosynthesis, respiration, root growth, and nutrient uptake, with diverse mechanisms involving cell destruction, oxidative homeostasis and photoinhibition. In some cases, allelochemicals can also have positive effects on plant growth and development.

- - Common bean is an important crop that often suffers from drought, but the right amount of copper can help, despite excess copper being harmful.
- - Researchers identified nine SMXL gene orthologues in common bean, discovering their varying responses to drought and copper stress, with some genes increasing and others decreasing in expression.
- - The study found that silencing the PvSMXL2 gene improves drought tolerance but does not help with copper tolerance, highlighting the specific roles of SMXL genes in managing abiotic stresses.
