In contrast,decreasing the amount of TAs in chloroplast
membranes has been shown to strongly enhance
high-temperature tolerance in plants.Cosuppression
by gene silencing of the chloroplast x-3 desaturases in
transgenic tobacco resulted in very low levels of TAs
and increased levels of DAs in the chloroplast membranes.
When compared to control plants,these
transgenic plants demonstrated resistance to high
temperature (36\2C) that was not transient.Moreover,
thermal denaturation of photosynthetic machinery
proteins was observed in the chloroplast membranes
of wild-type plants exposed to high temperature but not
in transgenic plants with decreased TAs (Iba 2002).
The effects of elevated temperature on the fatty acid
composition of storage lipids have been examined
extensively in developing seeds.For example,the
changes in soybean seed glycerolipid composition
observed at high temperatures (Wilson 2004; Rajcan
et al.2005; Hou et al.2006) were an increase in 18:1
and a decrease in polyunsaturated fatty acids
(18:2 + 18:3),a pattern similar to the one for plant
leaves acclimating to rising temperatures.
