文摘
- •
Glyoxylate cycle is active in scutellum of germinating barley seeds.
- •
Citrate and malate are abundant in scutellum and endosperm while succinate is not accumulated.
- •
Organic acids produced via glyoxylate cycle can participate in acidification of endosperm.
- •
Glyoxylate cycle can support amino acid synthesis in cereals during germination.
- •
Operation of the glyoxylate cycle leads to the increase in ATP/ADP and H2O2.
