Preparation of Corn Root Plasmalemma with Low Mg-ATPase Latency and High Electrogenic H Pumping Activity after Phase Partitioning.

abstract：:Wood is an important raw material and environmentally cost-effective renewable source of energy. However, the molecular biology of wood formation (i.e. secondary growth) is surprisingly understudied. A novel experimental system was employed to study the molecular regulation of secondary xylem formation in Arabidopsis....
