针叶树果实中含有丰富的抗坏血酸（阿萨）。阿萨生物合成途径上游3个酶的基因表达水平与两个金虎尾品种果实中阿萨含量相关。缩写：阿萨：抗坏血酸; PMI：磷酸甘露糖异构酶; PMM：磷酸甘露糖变位酶; GMP：GDP-d-甘露糖焦磷酸化酶; GME：GDP-d-甘露糖3 β，5 β-差向异构酶; GGP：GDP-1-半乳糖磷酸化酶; GPP：1-半乳糖-1-磷酸酶; GDH：1-半乳糖脱氢酶; GLDH：l-半乳糖酸-1，4-内酯脱氢酶
Acerola fruits contain abundant ascorbic acid (AsA). The gene expression levels of three upstream enzymes in the primary AsA biosynthesis pathway were correlated with AsA contents in the fruits of two acerola cultivars. Multiple overexpression of the enzymes increased AsA contents, suggesting their high expression is important for high AsA accumulation in acerola fruits and the breeding of AsA-rich plants.Abbreviations:AsA: ascorbic acid; PMI: phosphomannose isomerase; PMM: phosphomannomutase; GMP: GDP-d-mannose pyrophosphorylase; GME: GDP-d-mannose 3ʹ,5ʹ-epimerase; GGP: GDP-l-galactose phosphorylase; GPP:l-galactose-1-phosphate phosphatase; GDH:l-galactose dehydrogenase; GLDH:l-galactono-1,4-lactone dehydrogenase
