Use of growth retardants enables post-planting optimization of vegetative growth, which is particularly important given ongoing climate change. Mepiquat chloride is an economical and safe retardant widely applied in cotton farming, but it is not uniformly effective. Here, identification of its molecular target as the ent-copalyl diphosphate synthase that initiates gibberellin biosynthesis enabled the introduction of selective agrochemical inhibition, leaving intact more specialized metabolism important for resistance to biotic and abiotic stresses.

Faculdades Pequeno Príncipe Av Iguaçu, 333, 80230-020 Curitiba, Paraná, Brazil.
Neural tube defects (NTDs) are the second most common congenital anomaly and have been widely associated with exposure to pesticides. This systematic review which analyzes the association between parental exposure to pesticides and NTDs was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The search strategy was designed considering the population, exposure, controls, outcomes, and study design (PECOS).

Nucleic acid aptamers are single-stranded oligonucleotides that are selected through exponential enrichment (SELEX) technology from synthetic DNA/RNA libraries. These aptamers can specifically recognize and bind to target molecules, serving as specific recognition elements. Surface-enhanced Raman scattering (SERS) spectroscopy is an ultra-sensitive, non-destructive analytical technique that can rapidly acquire the "fingerprint information" of the measured molecules.

Background: Imported malaria from southern Mozambique drives low levels of disease transmission in KwaZulu-Natal, South Africa. Therefore, the South African Department of Health funded implementation of indoor residual spraying (IRS) in Mozambiquan districts identified as sources of malaria infection for border communities in KwaZulu-Natal. IRS was initiated in districts of Guija, Inharrime, Panda and Zavala.

The continual use of synthetic insecticides to control mosquito larvae has severe implications for human health and the ecosystem, highlighting the need for alternative natural insecticides. Macroalgae may be a good alternative because of their biologically active metabolites with distinctive chemical structures that have been reported for their insecticidal properties. The study aimed to investigate the potential of different extracts from Jania rubens (Linnaeus) J.

Short neuropeptide F (sNPF) is an insect-specific neuropeptide named for its C-terminal phenylalanine. It consists of 6-19 amino acids with a conserved RLRFa structure, regulating feeding, growth, circadian rhythms, and water-salt balance in insects. Its receptor belongs to GPCR-As and binds sNPF to regulate the insect nervous system.
