Lipids from Rice Anthers
The phosphatidylglycerols (PG), but no other lipid classes, from the chilling-sensitive plants, contain a large proportion of saturated molecular species, 1, 2-dipalmitoyl-PG and sn-1-palmitoyl-2-(trans-3)hexadecenoyl-PG, which undergo a thermotrophic phase transition at the room temperature range or above (Murata et al. 1982; Murata 1983; Murata and Yamaya 1984). The phase transition of cellular membranes induced by these saturated lipid molecules is proposed to be the primary event of the chilling injury.
