IDENTIFY CELL WALL FACTORS LIMITING DIGESTIBILITY & FORAGE UTILIZATION

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 为了在可持续奶牛养殖业中识别限制植物细胞壁消化和饲料利用的因素，我们将1.利用转基因木质素途径对植物进行表征，以开发提高饲料利用的新途径，并深入了解木质素组成对细胞壁消化和不可消化残留物形成的影响。2.确定难消化残留物的内在化学特性，以阐明限制其被奶牛消化并减少其负面影响的机制。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. To identify plant cell wall factors limiting digestibility and forage utilization in sustainable dairy farming, we will 1. Characterize plants with genetically modified lignin-pathways in order to develop novel approaches for improving forage utilization and provide insight into the effects of lignin composition on cell wall digestability and formation of indigestible residues. 2. Determine the intrinsic chemical characteristics of indigestible residues in order to elucidate mechanisms that limit their digestion by dairy cows and reduce their negative impact.
