    Notes: Abstract Oleosomes, up to 14μm in diameter, were found in mesophyll and bundle sheath cells of the flag and lower leaves of wheat cv Professeur Marchal. They develop in flag leaves at least 10 d before anthesis, possibly from fatty acids secreted by the plastids, and persist in mature and senescing leaf tissue. Oleosomes are bordered with an osmiophilic layer rather than a unit membrane. The major lipids of oleosomes, isolated 20 d after anthesis, are triacylglycerols (50%) and sterol or wax exter (34%). The dominant fatty acids of both lipid classes are plamitic (16:0) and stearic (18:0) acids which accounts for the low osmiophilia of the oleosomes. The function of the oleosomes is unknown but they may act as short-term energy reserves. Oleosomes persist in leaves infected with brown rust, even in cells penetrated by haustoria. Yellowish-brown oleosomes found in senescing and rust-infected leaves may be formed by the release and coalescence of pigmented plastoglobuli.

    Balloon-borne polarimetry (1996)
    Springer
    Solar physics 164 (1996), S. 403-415 
    Details
    ISSN: 1573-093X
    Keywords: Stratospheric balloon ; Antarctica ; Vector polarimetry ; Flares

    Topics: Physics
    Notes: Abstract For about two weeks in 1995, the balloon-borne Flare Genesis Experiment will continuously observe the Sun well above the turbulent, image-blurring layers of the Earth's atmosphere. The polarization-free 80 cm telescope will supply images to a liquid-crystal based vector magnetograph, which will measure magnetic features at a resolution of 0.2 arcsec. An electrically tunable lithium-niobate Fabry-Perot provides a spectral resolution of about 0.015 nm. In a follow-up series of Antarctic balloon flights, the Flare Genesis Experiment (FGE) will provide unprecedented details about sunspots, flares, magnetic elements, filaments, and the quiet solar atmosphere.
