Plumbagin as a new natural herbicide candidate for Sicyon angulatus control agent with the target 8-amino-7-oxononanoate synthase

Triazolyl phenyl disulfides: 8-Amino-7-oxononanoate synthase inhibitors as potential herbicides

“…Our laboratory has been performing molecular genetics dissection using the antisense approach to identify new target 8-amino-7-oxononanoate synthase (AONS) on the pathway of biotin biosynthesis and to characterize the phenotypic consequences of lossof-function mutations [6,7]. Biotin biosynthesis is understood in detail in Therefore, inhibition of the enzymes involved in the biotin biosynthesis pathway can cause irreparable damage to plants; for this reason, such enzymes can be useful targets for the rational design of inhibitors in the hopes of finding new herbicides [4,5].…”

“…In mutant plants with reduced amounts of glutamine synthetase activity, the target of glufosinate, reduction in glutamine synthetase activity of only 38% was sufficient to cause severe abnormalities Based on knowledge of pathway dynamics, such directed knock-outs can allow the screening of enzymes whose inhibition might be expected to have catastrophic effects in the plant. Hwang et al [6,7] argued that our knowledge of biochemical pathways in plants is incomplete, and the next major herbicide target may lie in an unexpected area of plant metabolism; knowledge in detail of how plants actually die as a result of inhibition of certain known targets is still ambiguous [25]. However, it can be predicted that herbicidal activity is somewhat connected with reducing the level of the target enzyme activity which leads to plant death.…”

“…Therefore, inhibition of the enzymes involved in the biotin biosynthesis pathway can cause irreparable damage to plants but be non-toxic to mammals; for this reason, such enzymes can be useful targets for the rational design of inhibitors in the hopes of finding new herbicides [4,5]. The validation of one potential herbicide target, 8-amino-7-oxononanoate synthase (AONS), was performed in vitro and in vivo with lead chemical triphenyltin acetate [6]; a natural compound, plumbagin (5-hydroxy-2-methyl-1,4-naphthoquinone), was reported as a potential AONS inhibiting herbicide [7].…”

Elicitation of Induced Resistance against Pectobacterium carotovorum and Pseudomonas syringae by Specific Individual Compounds Derived from Native Korean Plant Species

“…The specific compounds isolated from plant extracts were identified as described previously [65]. Briefly, each tissue was harvested and prepared following drying at room temperature for five days under shade conditions.…”
