Updated project metadata. With the aim of reveal the mechanism of Podophyllum Hexandrum Royle adaption to high altitude, MALDI-TOF-MS/MS in combination with 2-DE was used to identify the differentially expressed proteins in leaves of Podophyllum Hexandrum Royle between low altitude (2200m) and high altitude (3100m), 65 differentially expressed proteins was identifed and 44 was up-regulated in high altitude compared tolow altitude.
