英语翻译
Trienoic fatty acids (TAs),hexadecatrienoic acid
(16:3) and linolenic acid (18:3),are the major polyunsaturated
fatty acid species in membrane lipids.
Increasing TAs in chloroplast membranes has been
shown to enhance low temperature tolerance in plants
during the early growth stage (Iba 2002).Overexpressing
the Arabidopsis chloroplast x-3 desaturase genes
FAD7 or FAD8 in tobacco increased TAs and
decreased dienoic fatty acids (DAs),hexadecadienoic
acid (16:2) and linoleic acid (18:2),in leaf tissue
(Nishiuchi and Ida 1998).Comparison of wild type
with transgenic tobacco showed that chilling tolerancewas achieved in transgenic seedlings,but not in mature
plants (Kodama et al 1995).When the levels of TAs
in tobacco phospholipids,the main constituent of
extrachloroplastic membranes,were increased by
overexpressing an ER localized x-3 fatty acid desaturase
FAD3 gene,no significant differences were
detected between wild type and transgenic tobacco for
resistance to chilling and freezing (Hamada et al.
1998).
