Natural products are one of the resources for discovering novel pesticide leads. Here, by molecular hybridization between natural enamino diketone skeleton and reported herbicide lead compound I, a series 3-(1-aminoethylidene)-6-methyl-2H-pyran-2,4(3H)-dione derivatives (APD) were rationally designed, synthesized tested herbicidal activity in greenhouse. The bioassay results showed that most ta...

Abstract Background The identification of chromosomes among Avena species have been studied by C-banding and in situ hybridization. However, the complicated results from several cytogenetic nomenclatures for identifying oat are often contradictory. A universal karyotyping nomenclature system precise chromosome comparative evolutionary studies would be essential genus based on recently released ...
