IDENTIFY CELL WALL FACTORS LIMITING DIGESTIBILITY & FORAGE UTILIZATION

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得主要资金， 因此可以在其他CRISP条目中表示。列出的机构是 研究中心，而研究中心不一定是研究者所在的机构。 为了确定植物细胞壁因素限制消化率和饲料利用可持续奶牛养殖，我们将1。表征具有转基因木质素途径的植物，以开发用于改善饲料利用的新方法，并提供对木质素组成对细胞壁稳定性和形成不可消化残留物的影响的见解。2.确定难消化残留物的内在化学特性，以阐明限制奶牛消化的机制，并减少其负面影响。

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.
