“…In previous studies, it was found that large-scale weeding mainly depends on chemical herbicides. At the same time, chemical herbicides can cause some environmental pollution problems, increase weed resistance to herbicides, and change weed population structure 40 . Biological herbicides are presently being used as a new weed control method because of their wide herbicide spectrum, environmental protection and long persistence 41,42 .…”

Wild oat (Avena fatua L.) is among the most harmful of gramineous weeds infiltrating crops, resulting in reductions in crop quality and yield. The moderately halophilic bacterium Bacillus altitudinis D30202 has a good biological control effect on wild oat. In order to explore the biocontrol mechanism of B. altitudinis D30202, through whole-genome sequencing analysis, we explored the genome composition of B. altitudinis D30202, and conducted research on the prediction of herbicide secondary metabolite synthesis gene clusters to provide a reference for follow-up research on the mechanism of biological control of weeds.The whole gene sequencing results showed that the genome size of the B. altitudinis D30202 strain was 3,777,154 bp, the GC content was 41.32%, and there were a total of 3809 coding genes. In addition, The strain can also produce substances that may have herbicidal activity, including 4-hydroxy-3-methoxycinnamic acid and indole derivative. Online predictive analysis found that the strain has 10 secondary metabolite gene clusters. The results of whole-genome sequencing obtained in this study provide an information basis for the research and development of the molecular mechanism of weed inhibition. Genomic information reveals the interaction between several enzyme genes and wild oat, provides a reference for the study of metabolite synthesis and regulatory mechanisms, and lays the foundation for the development of new biological control agents.

“…These recent concerns have encouraged researches focusing on isolation, quantification and characterization of new bioactive compounds with effectiveness and low toxicity to application in the agricultural sector [100]. Nonetheless, studies show that many plants secrete specific toxins with antimicrobial action [101][102][103]. One of the main examples is the allelochemicals produced by plants that affect weeds and do not damage crops, due to the difference in sensitivity in the target enzymes or the occurrence of particular receptors in weeds that react directly to the action of secreted biocompounds [104].…”

The growing development of biological products highlights the social and environmental responsibility that several industrial companies are facing in recent years. In this context, the advancement of bioprocessing as an alternative for exploring the potential of ecologically based products, especially in biofuels, food, and agro-industrial business, exposes the rational efficiency of the application of renewable sources in different industrial segments. Industries strongly associated with food production concentrate large amounts of wastes rich in bioactive compounds. A range of highly effective technologies has been highly explored to recover large concentrations of prominent compounds present in these materials. The advances in this scenario assurance value addition to these by-products, in addition to highlighting their various technological applications, considering the biorefinery and ecologically based production concepts. Accordingly, this review article described a detailed and systematic approach to the importance of using bioactive compounds and exploring the main sources of these elements. Also, some recent and innovative research that has achieved encouraging results was highlighted. Furthermore, the study included the main extraction technologies that have been investigated as a strategy of prospecting the application of bioactive compounds and optimizing the processes for obtaining natural compounds from plant sources. Finally, future outlooks were presented to contribute to the innovative opportunities and applicability of highly promising technologies and manipulations of bioactive compounds from a range of perspectives.

“…Ocimum basilicum extract can also be applied as a biodegradable herbicide due to the content of allelochemicals. Mekky et al (2019) pointed to the richness of the chemical composition of the basil extract, which contained 2-cyclopenten-1-one, 2,5,5-trimethyl, 3-cyano-5,5-dimethyltetrafuran-2-one, linoleic acid, methyl ester, 9,12-octadecadienoic acid (Z,Z), phthalic acid, di(2-propylpentyl) ester, 1,2-benzenedicarboxylic acid, 6-octadecenoic acid, methyl ester, (Z), 2,3-bis(acetyloxy) propyl laurate, squalene, thymol, 2-cyclohexen-1-one, 4-(3-hydroxy-1-butenyl)-3,5,5-trim ethyl, hexadecenoic acid, methyl ester, cis-linalool oxide. Khare et al (2019) showed that essential oils (EOs) extracted from Lemon eucalyptus (Eucalyptus citriodora), basil (O. basilicum), field mint (Mentha arvensis) demonstrated the phytotoxicity on weeds.…”

Plants due to the high content of various bioactive compounds are the main raw material for production of valuable, and useful bio-products (e.g., food, cosmetics, medicines, biostimulants, biopesticides, and feed). Different plant parts, for instance: seeds, fruits, flowers, stems, leaves, and roots can be used for their manufacture. Nowadays, there is a clear need to develop new, efficient, and environmentally safe methods of stimulation of plant, growth and crop protection. Plant-based extracts are new, natural, and multi-compounds products that could be used for these purposes. They possess antifungal, antimicrobial, antiparasitic, antiprotozoal, antioxidant, medicinal, aromatic, and anti-inflammatory properties. This group of natural products has the potential to become a new generation of bio-products suitable for use in sustainable agriculture. The purpose of this review is to provide an overview of the literature describing the impact of plant-derived extracts/biostimulants (PDBs) on crops grown in controlled, and real conditions as well as under various abiotic and biotic stresses; the extraction methods used to obtain PDBs, and the specific constituents responsible for their biostimulating activity. The application of these bio-products could be beneficial for sustainable production, due to several advantages, such as low toxicity to humans and the environment, enhanced resistance of cultivated plants to biotic and abiotic stress, increased yields and quality of crops, as well as the reduction in the use of mineral fertilisers and pesticides. However, deeper cooperation between industrial and academic research is required to accelerate the development of new environmentally safe solutions for future agriculture. Highlights - Higher plants constitute a rich source of various bioactive compounds for the production of useful natural products. - The importance of the proper choice of extraction method and solvent to process and preserve the desired substances.- Plant extracts as biostimulants and plant protection products for use in modern and sustainable agriculture. - The positive effects of plant-based extracts on plants cultivated under normal and unfavourable conditions.- Plant extracts as a new generation of eco-friendly products for the increment of the production of high-quality food.
