Protective effect of glutamine on the main and adjacent organs damaged by ischemia-reperfusion in rats.

abstract：:The morphogenesis of galls occurs by the redifferentiation of cells that assume new functions in the modified host plant organs. The redifferentiated cells in the galls of Nothotrioza myrtoidis on Psidium myrtoides have low complexity metabolism and are photosynthesis-deficient. These galls were studied in search for ...
