the respiration of a susceptible mutant barley ( the yellow-green virescent mutant of the variety himalaya ) when grown in the light at 11 degrees was not changed by infection although the characteristic respiratory rise occurred in plants grown at 15 degrees . at the lower temperature chloroplasts fail to develop in this mutant , although development is normal at 15 degrees .it is suggested that the pathogen is not directly responsible for the increase in respiration in green leaves , rather that this is a response in the host cells to a loss of photosynthetic capacity .
