New cytotoxic xenia diterpenoids from the Formosan soft coral Xenia umbellata.
Seven new cytotoxic xenicane-type diterpenoids, 9-deoxyxeniloide-E (1), 9-deoxy-7,8-epoxyxeniloide-E (2), xeniolide-G (3), 9-deoxyxenialactol-C (4), xenibecin (5), xeniolide-H (6), and xenitacin (7), were isolated from the methylene chloride solubles of the Formosan soft coral Xenia umbellata. The structures were elucidated by 1D and 2D NMR spectral analysis, and their cytotoxicity against sele...
متن کاملXenia and Metaxenia in Persian Walnut (Juglans regia L.)
In 2007 and 2008, the influence of pollen source on the shell and kernel traits of resulting seeds and on fruit set was examined to evaluate the potential for Xenia or Metaxenia in Persian walnut. Pistillate flowers of ‘Jamal’, ‘Chandler’, ‘Hartley’ and ‘Pedro’ were crossed with the pollen of ‘Serr’, ‘Z60’ and ‘Damavand’. The pistillate flowers on each female parent were covered about one week...
متن کاملInorganic nutrient availability affects organic matter fluxes and metabolic activity in the soft coral genus Xenia.
The release of organic matter (OM) by scleractinian corals represents a key physiological process that importantly contributes to coral reef ecosystem functioning, and is affected by inorganic nutrient availability. Although OM fluxes have been studied for several dominant reef taxa, no information is available for soft corals, one of the major benthic groups in tropical reef environments. Thus...
متن کاملSynthesis of Xenia diterpenoids and related metabolites isolated from marine organisms
This review describes strategies for the chemical synthesis of xenicane diterpenoids and structurally related metabolites. Selected members from the four different subclasses of the Xenia diterpenoid family, the xenicins, xeniolides, xeniaphyllanes and xeniaethers, are presented. The synthetic strategies are discussed with an emphasis on the individual key reactions for the construction of the ...
متن کاملXenia Effects on Quality of Maize Female Inbred in Production of Hybrid Seeds
In Maize (Zea maize L.), cost of hybrid seed production is directly related to the yield and quality of seed obtained per hectare of female parent. It is also important to consider the effects that a male parent can exert on the development of hybrid seed in the female parent. This effect is known as xenia. The objectives of this study were to evaluate xenia effects on 1) yield as 80K units, 2)...
