Article Synopsis
- Soil autotoxic chemosensory substances, particularly benzoic acid, significantly limit the growth and yield of certain plants, yet the specific impact of benzoic acid on growth remains unclear.
- Research showed that exposure to 200 mmol/L of benzoic acid reduced various growth metrics (height, root length, fresh weight) while increasing root enzyme activity and the accumulation of polysaccharides and lobetyolins.
- The study identified nearly 8,000 differentially expressed genes influenced by benzoic acid, suggesting that it may enhance lobetyolin content and gene expression related to key metabolic pathways, leading to increased plant resilience against stress.
Normal root growth is essential for the plant uptake of soil nutrients and water. However, exogenous HO inhibits the gravitropic growth of pea primary roots. It has been shown that CaCl application can alleviate HO inhibition, but the exact alleviation mechanism is not clear.

- The study examines the growth and lobetyolin synthesis of C. pilosula under continuous cropping stress, revealing that such stress significantly hinders plant growth and reduces lobetyolin levels.
- Using advanced techniques like high-performance liquid chromatography and transcriptome analysis, researchers identified a potential biosynthesis pathway for lobetyolin linked to specific gene expressions.
- Findings indicate that soil properties and microorganisms play a crucial role in root growth and lobetyolin production, highlighting their importance in addressing the challenges posed by continuous cropping in cultivation practices.
Acetochlor, as a commonly used pre-emergent herbicide, can be toxic to crops and affect production if used improperly. However, the toxic mechanism of acetochlor on plants is not fully understood. The present study used a combination of transcriptomic analysis and physiological measurements to investigate the effects of short-term (15-day) exposure to different concentrations of acetochlor (1, 10, 20 mg/kg) on the morphology, physiology, and transcriptional levels of pea seedlings, aiming to elucidate the toxic response and resistance mechanisms in pea seedlings under herbicide stress.
