A proposed model for Ricinus communis during early seed imbibition in response to cold stress. The up-accumulated DAPS and increased content of acetyl-CoA and sucrose were indicated by the red arrow; the decreased content of ATP were indicated by blue arrow. Abbreviations: Glu-6P, Glucose 6-phosphate; 6PGDL, 6-phosphogluconolactone; G6PDH, glucose-6-phosphate 1-dehydrogenase; 6PGL, 6-phosphogluconolactonase; Gluconate-6P, 6-phosphogluconate; Ribulose-5P, Ribulose-5-phosphate; Xylulose-5P, Xylulose-5-phosphate; RPE, Ribulose-phosphate 3-epimerase; G3P, Glyceraldehyde 3-phosphate; KASI, β-ketoacyl-acyl carrier protein synthase I; KASII, β-ketoacyl-acyl carrier protein synthase II; KASIII, β-ketoacyl-acyl carrier protein synthase III. Solid lines denoted proven connections in plants, whereas broken lines represented connections that might exist in plants.
