摘要： DNA constructs comprising a first DNA segment that corresponds to at least a portion of a gene in the monolignol biosynthetic pathway, a spacer DNA segment, and a second DNA segment that is complementary to the first DNA segment can be used to reduce or modulate the lignin content in plants. In some embodiments, DNA constructs comprise at a least a portion of a gene for 4CL, C3H, CCR, C4H or CCoAOMT. Vascular-preferred and constitutive promoters can be used to drive expression of the constructs.

摘要： DNA constructs comprising a first DNA segment that corresponds to at least a portion of a gene in the monolignol biosynthetic pathway, a spacer DNA segment, and a second DNA segment that is complementary to the first DNA segment can be used to reduce or modulate the lignin content in plants. In some embodiments, DNA constructs comprise at a least a portion of a gene for 4CL, C3H, CCR, C4H, Cald5H, 5AD or CCoAOMT. Vascular-preferred and constitutive promoters can be used to drive expression of the constructs.

摘要翻译： 包含对应于单螺旋藻生物合成途径中的基因的至少一部分的第一DNA片段，间隔区DNA片段和与第一DNA片段互补的第二DNA片段的DNA构建体可用于减少或调节木质素 植物中的内容。 在一些实施方案中，DNA构建体包含4CL，C3H，CCR，C4H，Cald5H，5AD或CCoAOMT的基因的至少一部分。 血管优选和组成型启动子可用于驱动构建体的表达。
