A new eremophilane sesquiterpene, 10α-hydroxy-3-oxoeremophil-1(2),7(11),8(9)-trien-8(12)-olide (1), was isolated from Ligularia veitchiana. The structure of the new compound was elucidated by physical and spectroscopic data analysis, including 1D NMR and 2D NMR and HR-ESI-MS. Compound 1 showed inhibitory activity against the second-stage juveniles (J2) of Meloidogyne incognita with an LC50 value of...
Background Brassica rapa is an economically important crop and a model plant for studies concerning polyploidization and the evolution of extreme morphology. The multinational B. rapa Genome Sequencing Project (BrGSP) was launched in 2003. In 2008, next generation sequencing technology was used to sequence the B. rapa genome. Several maps concerning B. rapa pseudochromosome assembly have been published...
We report a MEMS-integrated on-chip tunable resonator consisting of two coupled one-dimensional (1D) Photonic Crystal nanocavities capable of achieving a relatively large tuning range with no significant deterioration of quality factor and sufficiently large transmissions.
