“…These molecules contain oxygen atoms and easily excited double and triple bonds and are susceptible to release into the environment ( Zhang et al., 2007b ; Yu et al., 2015 ). Autotoxins are generally divided into water-soluble organic acids, linear alcohols, aliphatic aldehydes, and alkenes; simple phenols, benzoic acids, and their derivatives; simple unsaturated lactones, long-chain fatty acids, and polyacetylenes; naphthoquinone, anthraquinone, and quinone compounds; cinnamic acids and their derivatives; coumarins, tannins, terpenoids, and sterides; amino acids and polypeptides; alkaloids and cyanohydrins; sulfides and glucosinolates; and purines and nucleosides ( Zhang et al., 2011b ; Scavo et al., 2018 ; Blum, 2019 ). Many autotoxins associated with continuous cropping obstacles ( p -hydroxybenzoic acid, homovanillic acid, vanillic acid, vanillin, cinnamic acid, ferulic acid, cumaric acid, benzoic acid, sesamin, momilactone B, etc.)…”

Tobacco belongs to the family Solanaceae, which easily forms continuous cropping obstacles. Continuous cropping exacerbates the accumulation of autotoxins in tobacco rhizospheric soil, affects the normal metabolism and growth of plants, changes soil microecology, and severely reduces the yield and quality of tobacco. In this study, the types and composition of tobacco autotoxins under continuous cropping systems are summarized, and a model is proposed, suggesting that autotoxins can cause toxicity to tobacco plants at the cell level, plant-growth level, and physiological process level, negatively affecting soil microbial life activities, population number, and community structure and disrupting soil microecology. A combined strategy for managing tobacco autotoxicity is proposed based on the breeding of superior varieties, and this approach can be combined with adjustments to cropping systems, the induction of plant immunity, and the optimization of cultivation and biological control measures. Additionally, future research directions are suggested and challenges associated with autotoxicity are provided. This study aims to serve as a reference and provide inspirations needed to develop green and sustainable strategies and alleviate the continuous cropping obstacles of tobacco. It also acts as a reference for resolving continuous cropping challenges in other crops.

Ranunculus sceleratus L. (celery-leaved buttercup) is a herbaceous plant grows in wet and moist habitats and is native to temperate and boreal North America and Eurasia. Moreover, it is listed as an invasive weed in northern Africa, Europe and Asia. This study aimed to determine some secondary products in R. sceleratus (Shoot and Root system) collected from canal banks of drains, Nile Delta, Egypt and to demonstrate their antioxidant and allelopathic potential. Results revealed that, methanolic extract of R. sceleratus rich in phenols, saponins and tannins. The antioxidant activity of the R. sceleratus has IC50 value of 0.37 mg/ml and 0.34 mg/ml for shoot and root, respectively, compared to 0.15 mg/ml for catechol. At 400 mg/ml, Chenopodium murale germination was inhibited by 79.74% and 92.64 for shoot and root extract, respectively, compared to control. However, the shoot growth was reduced by 76.06 % and 87.96 %, with the same sequence. The root growth was more sensitive to the allelopathic effect compared to the shoot, where it was inhibited by 82.68% and 98.67%, respectively, compared to control at the highest concentration. The obtained results on this invisive weed R. sceleratus could be a source of eco-friendly bioherbicides against C. murale and as a source of antioxidants.
