The recent progress in cloning and characterization of plant cuticular wax genes was reviewed and the prospects of the research in wax genes was also discussed.

作者对近年来角质层蜡质基因的研究进展进行综述，同时也对蜡质基因的研究前景提出一些看法。

Quantification analysis of wax composition by gc-ms revealed a significant reduction of total cuticular wax in the mutant and increase of total cuticular wax in the over-expression plants.

利用气相色谱质谱联用仪对蜡质成分进行定量分析表明总角质层蜡质在过量表达植株中显著升高而在突变体中降低。

These results indicate that cuticular wax content in flag leaf is closely related to drought tolerance and can be used as a physiological indicator of drought resistance in wheat selection.

以上结果表明，蜡质能够提高小麦的抗旱性，旗叶蜡质含量可以作为抗旱小麦品种的选择指标。
