Dolichols of the fern Matteucia struthiopteris.
Dolichols isolated from leaves of the fern Matteucia struthiopteris were present as a mixture of prenologues composed of 14 up to 20 isoprene units with Dol-16 dominating. They comprised approximately 0.004% of the fresh weight of fresh plant tissue and were accompanied by traces of polyprenols (Pren-14 up to Pren-17, Pren-16 dominating). Their structure was confirmed by electropray ionization ...
متن کاملChloroplast Division in the Gametophyte of the Fern Matteuccia Struthiopteris (l.) Todaro
The mechanism by which fully developed chloroplasts divide has been reported to consist of an initial constriction around the entire chloroplast, which is followed by a p inching into two daugh te r chloroplasts. Constr ict ion is accompanied by fusion of the inner and outer layers of the chloroplast membrane . Such a division has been documented by electron microscopy for the brown alga, Fucus...
متن کاملCytological Features of the Egg Cell Protoplasts Isolated from Gametophytes of Fern, Struthiopteris niponica (Kunze) Nakai
Egg cell protoplasts were isolated from the gametophyte of the fern, Struthiopteris niponica (Kunze) Nakai. Archegonia were excised from the prothallia and then digested in an enzyme solution that contained Cellulase "Onozuka" RS and Macerozyme R-10. After 3 hours of incubation, the egg cell protoplasts had separated completely from the somatic cells. The protoplasts had such cytological featur...
متن کاملخصوصیات حشره‌کشی و ضدتغذیه‌ای عصاره متانولی گیاه سرخس شترمرغی (Matteucia struthiopteris (L.) Tod) بر شب‌پره پشت الماسی (Plutella xylostella L.)
شب‌پره پشت الماسی آفت عمده محصولات خانواده چلیپائیان است که به بسیاری از حشره‌کش‌های شیمیایی مقاوم شده‌است. در سال‌های اخیر استفاده از متابولیت‌های ثانویه با دارا بودن خواص ضدتغذیه‌ای و حشره‌کشی نقش مهمی را در کنترل آفات بر عهده دارد. در این مطالعه، حشره‌کشی عصاره متانولی سرخس شترمرغی (Matteucia struthiopteris (L.) Tod) بر لارو سن سوم شب‌پره پشت الماسی (Plutella xylostella L.) مورد بررسی قرار گ...
متن کاملLiquid-chromatographic determination of dolichols in urine.
A reversed-phase "high-performance" liquid chromatographic assay for dolichols-18, -19 and -20 in urine is described. Dolichols are extracted from urine by using C18 cartridges and are chromatographed with a mobile phase consisting of 2-propanol/methanol, the effluent being monitored at 210 nm. The useful lower limit of sensitivity for quantification is 4 pmol (5 ng) of each dolichol per 5-micr...
