植物中转录因子具备广泛调节下游基因的功
能。近年来，以调节与脂肪酸合成相关转录因子表
达水平，提高受体材料中油脂含量的研究越来越受
重视。目前，应用较多的转录因子编码基因包括
LEC1
(
LEAFY COTYLEDON1
)
、
LEC1-LIKE
以及
WRI1
等，已经在玉米
(Shen et al., 2010)
和油菜
(Tan et
al., 2011)
等作物中获得良好改良效果。故而，转录
因子研究为植物油脂遗传改良开辟了新的路径。
总之，棉籽油份改良工作还有很大空间。长期
以来，棉籽只作为棉花的副产品对待；棉籽油份含
量遗传及其品质改良研究滞后的局面，随着油脂合
成的分子机理研究深入、油脂合成相关基因及其功
能鉴定工作推进，将会大有改观。
