Respiration under pathogenesis

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Respiration is stimulated in leaves of groundnut plants following infection byCercospora personata. The degree of stimulation varies with the variety of the host plant. A decreased sensitivity to malonate and an accumulation of sugars are noted in the infected tissues. The actual increase in oxygen uptake induced by 2, 4-dinitrophenol (DNP) is almost the same in healthy and infected tissues although when expressed as a percentage of the control rate (i.e.,—DNP) the stimulation is less in infected tissues. The culture filtrate ofCercospora personata induces marked stimulation in respiratory rate of groundnut leaf tissue.
