Long Term Effects of Weightlessness on a Biological System-Isoenzyme Analysis: Supplemental Report (COS 1129-13)
Principal Investigator
Research Area:
Plant biology
Species Studied
Scientific Name: Daucus carota Species: Carrot

Description
Objectives:

The main objective of the gel electrophoresis study was to determine if weightlessness or other gravity treatments altered the isoenzyme profile of crown gall tumors. This objective was extended to include nontumored cortex and stele tissue. Although tumor growth in weightlessness was minimal, and the amount of material available for study was limited, it was decided to proceed with electrophoretic analysis where a sufficient amount of tumor tissue was available.
