Fig. 5. mRNA transcript number and corresponding fold-change in expression levels of five phospholipase genes in winter wheat accession 442 during 4 wk of cold acclimation at 4°C. All fold-change values are expressed relative to initial values, arbitrarily set to a value of one. The gene identification and the GenBank or TIGR (TC) sequences they were based on were A–Phospholipase C, TC148099; B–Phospholipase D, BE490064; C–Phospholipase A₂, CA654135; D–GDSL lipase/hydrolase, TC143709; E–Lysophospholipase, TC171605. Error bars indicate ± one standard error unit.
