zogenes are differentiated cells capable of the biosynthesis of secondary metabolites. Hairy roots also have a high rate of proliferation. They are therefore expected to become widely used culture systems for the production of useful secondary metabolites and for studies on the production of biologically active compounds and transformation of organic substrates. We reported the production of a ...

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Carbon Dioxide and Flowering in Pharbitis nil Choisy.
The effects of photoperiod on floral and vegetative development of Pharbitis nil were modified by atmospheric CO(2) concentrations maintained during plant growth. Short day (SD) photoperiods caused rapid flowering in Pharbitis plants growing in 0.03 or 0.1% CO(2), while plants in long day (LD) conditions remained vegetative. At 1 or 5% CO(2), however, flower buds were developed under both the S...
متن کاملTwo new phenolic amides from the seeds of Pharbitis nil.
Two new phenolic amides, pharnilatins A (1) and B (2), were isolated from the seeds of Pharbitis nil. These new compounds possess a p-coumaroyl unit with a structurally unique side chain, (2S,3S)-2,3-dihydroxyputrescine. The chemical structures and absolute stereochemistries of the new compounds were determined on the basis of spectroscopic analyses including 1D- and 2D-NMR experiments and chem...
