Characterization of polymorphic microsatellite loci in Yucca filamentosa.
Yuccas and their pollinator moths are a textbook example of mutualism, yet we lack sufficiently variable markers to properly study the population genetics of the plants. We characterized 13 polymorphic microsatellite loci for Yucca filamentosa by screening primers derived from an expressed sequence tag database. We found four to 13 alleles per locus and the observed heterozygosity ranged from 0...
متن کاملChemistry and geographic variation of floral scent in Yucca filamentosa (Agavaceae).
We identified volatiles from the floral headspace of Yucca filamentosa using gas chromatography and mass spectrometry and analyzed floral scent composition and variation among populations pollinated by different yucca moth species. Twenty-one scent compounds were repeatedly identified and most could be categorized into two major classes: (1) homoterpenes derived from the sesquiterpene alcohol n...
متن کاملارزیابی کارایی گیاه یوکا (Yucca filamentosa wood) در حذف ازت و فسفر درتصفیه فاضلاب روستایی
سامانه تالابهای مصنوعی از جمله روشهای تصفیه فاضلاب شهری و صنعتی بوده که از لحاظ مصرف انرژی و هزینه بسیار مقرون به صرفه می‌باشد که به دو صورت سطحی (تالاب با سطح آزاد آب) و تالاب زیرسطحی می‌باشد. در این تحقیق، حذف ازت و فسفر به وسیله گیاه‌یوکا (Yucca filamentosa wood) در محیط تالاب مصنوعی با جریان زیرسطحی افقی از شبکه فاضلاب روستای مرادتپه از توابع شهرستان اشتهارد، استان ...
متن کاملFeeding saponin-containing Yucca schidigera and Quillaja saponaria to decrease enteric methane production in dairy cows.
An experiment was conducted in vitro to determine whether the addition of saponin-containing Yucca schidigera or Quillaja saponaria reduces methane production without impairing ruminal fermentation or fiber digestion. A slightly lower dose of saponin was then fed to lactating dairy cows to evaluate effects on ruminal fermentation, methane production, total-tract nutrient digestibility, and milk...
متن کاملSpectrophotometric determination of saponin in Yucca extract used as food additive.
A spectrophotometric method was developed for the determination of saponin in Yucca extract or its preparation for food additive use. A saponin fraction of Yucca extract was prepared by column chromatography with porous polymer, and hydrolyzed with a 2 mol/L mixture of hydrochloric acid-ethanol (1 + 1) to generate sapogenin. Sapogenin amounts were determined by measuring absorbance at 430 nm, b...
