The polar lipid composition of extreme halophiles appears to be correlated with their taxonomic classification on the level of the genera so far distinguished [4,5,10,32, 50-52,54] Halobacterium, Haloarcula, Haloferax, Halococcus, Natronobacterium and Natronococcus (Table 1). All of these genera were found to contain C2o-C2o-archaeol PGP-Me (4A) as the major phospholipid, C2o-C2o-archaeol PG (3) and PGS (5) as minor phospholipids, and small to trace amounts of archaeol PA (6) [5,10,11,32,40] (see Table 1), with the following exceptions (a) PGS is characteristically absent...

Table I. Polar Lipid Composition of Potato Leaves and P. infestans. Fungal cultures were grown in liquid French bean media (4) for 14 days at 14° without shaking. Lipids were extracted (42) separated by 2-dimensional TLC (18). Individual spots were identified by comparison with standards, scraped from TLC plates, and analyzed for phosphorous (6) and hexose (43).

Under water stress, polar lipid composition of leaves undergoes noticeable changes ( Pham Thi et al.l982). On the other hand, recent works (Murata 1983) have demonstrated the existence of a relationship between molecular species composition of plant lipids, particularly of PG, and chilling sensitivity. In this paper, we examine the influence of water deficits on the molecular species composition of the main polar lipids from two varieties of Cowpea. ...

We have analyzed the polar lipid composition of mitochondria (from both green and non-green tissues), peroxisomes, chloroplasts and non-green plastids. Some experiments have also been performed with isolated cells from sycamore, cultivated in liquid suspension. In this last case, a specific parameter for the culture, i.e. the oxygen content of the medium, has to be taken into account as far as the fatty acid content of the membrane glycerolipids is concerned .

POLAR LIPID COMPOSITION, PHOTOSYNTHETIC ACTIVITY AND CHLOROPHYLL-PROTEIN COMPLEXES OF CHLOROPLASTS FROM HEMIPARASITIC ANGIOSPERMS ORIGINATING FROM TEMPERATE AND TROPICAL AREAS... 

This study showed that chloroplasts from hemiparasitic plants reveal a trend for low values of chlorophyll and polar lipids while the protein content is less affected. "Tropical chlroroplasts present marked changes in polar lipid composition along with a decrease in unsaturation of fatty acids. Chloroplasts from all hemiparasitic plants are capable of a more or less limited photosynthesis, probably reflecting the degree of dependence on the host.
