“…Anise oil enhances thermotolerance and antiviral responses by triggering salicylic acid (SA) and jasmonic acid (JA)-associated defense pathways in tomato (Tsai et al, 2019). 4 0 ,5,7-trihydroxy-3,6-dimethoxyflavone (jaceosidin), a 6-O-methylated flavonoid, has insecticidal activity against the mosquito Aedes aegypti and free radical scavenging activities (Al-Massarani et al, 2021). Jaceosidin enhances resistance against necrotrophic and biotrophic plant pathogens by SA and JA signaling (Song et al, 2013).…”

MicroRNAs (miRNAs) are small regulatory RNAs that participate in various biological processes by silencing target genes. In Arabidopsis, microRNA163 (miR163) was found to be involved in seed germination, root development, and biotic resistance. However, the regulatory roles of miR163 remain unclear. In the current study, the mir163 mutant was investigated to comprehensively understand and characterize its functions in Arabidopsis. RNA‐sequencing and Gene Ontology enrichment analyses revealed that miR163 might be involved in “response to stimulus” and “metabolic process”. Interestingly, “response to stress”, including heat, cold, and oxidative stress, was enriched under the subcategory of “response to stimulus”. We observed that miR163 and PXMT were repressed and induced under heat stress, respectively. Furthermore, the study detected significant differences in seed germination rate, hypocotyl length, and survival rate, indicating a variation in the thermotolerance between WT and mir163 mutant. The results revealed that the mir163 mutant had a lesser degree of germination inhibition by heat treatment than WT. In addition, the mir163 mutant showed a better survival rate and longer hypocotyl length under heat treatment than the WT. The metabolomes of WT and mir163 mutant were further analyzed. The contents of benzene derivatives and flavonoids were affected by miR163, which could enhance plants' defense abilities. In conclusion, miR163/targets regulated the expression of stress‐responsive genes and the accumulation of defense‐related metabolites to alter stress tolerance.

“…This compound belongs to the class of ketone sesquiterpenoids produced from the mevalonate acid pathway which has activity as an anti-feedant, hormone, antimicrobial, antibiotic and toxin as well as a plant growth regulator [25]. α-cyperone is also found in the rhizome and tuber oils of nutgrass from South Africa and Saudi Arabia and in the essential oil of the nutgrass chemotypes (types H, K, M, and O) in Asia [26,27]. This compound has good antioxidant activity, has a protective effect against DNA damage, a cytotoxic effect on human SH-SY5Y neuroblastoma cells, and also an antibacterial effect against foodborne pathogens [28].…”

Environmentally friendly weed control is highly recommended to be implemented in agriculture. The objective of this research was to assess the herbicidal efficacy of n-hexane, ethyl acetate, and methanol extracts derived from the tuber of Cyperus rotundus L. on Amaranthus spinosus L. The tuber was consecutively extricated with n-hexane, ethyl acetate, and methanol. These extracts were given to A. spinosus in pot culture at concentrations of 5%, 10%, 15%, and 20%.The herbicide (2,4-D at 0.686 kg a.i. ha−1) and distilled water were acted as positive and negative controls. The extract had variable effects on weed control percentage, leaf area, root length, shoot and root dry weight of A. spinosus. Major compounds in GC-MS in n-hexane of C. rotundus extract were: 7-Isopropenyl-1, 4a- dimethy l-4,4a,5,6,7,8-hexahydro-3H-naphthalen-2-one (19.60%), phthalic acid (7%), dibutyl phthalate (3.97%); in ethyl acetat extract were propanetriol, 1-acetate (37,40%) and 7 Isopropenyl-1,4a-dimethyl-4,4a,5,6,7,8-hexahyro-3H-naphthalen-2-one (6.42%); in methanol extract were d-glycero-d-ido-heptose (21.31%) and octaethylene glycol monododecyl ether (39.15%). The 20% of those extracts causing 53.33%, 64.33% and 55.33 destruction of A. spinosus respectively at 14 Days After Aplication. Thus, ethyl acetate is the most potent herbicide extract to be developed as an agent against A. spinosus.
