英文摘要：

Four L- ascorbic acid（ As A） biosynthetic routes have been proposed in higher plants and most of genes associated with As A biosynthesis have been identified in recent years. Currently,research advances in the genes and their putative functions involved in the As A biosynthetic pathways were summarized.
