IDENTIFY CELL WALL FACTORS LIMITING DIGESTIBILITY & FORAGE UTILIZATION

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。为了确定在可持续奶牛养殖中限制消化率和饲料利用的植物细胞壁因子，我们将1。利用转基因木质素途径对植物进行表征，以开发提高牧草利用率的新方法，并深入了解木质素组成对细胞壁消化率和不可消化残留物形成的影响。2. 确定不可消化残留物的内在化学特性，以阐明限制其被奶牛消化和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.
