Physiological Variables Influenced by ' Liberibacter asiaticus' Infection in Two Citrus Species.

' Liberibacter asiaticus' is the bacterium associated with the citrus disease known as huanglongbing (HLB). This study evaluated the influence of ' L. asiaticus' infection on a number of key plant physiological variables concerning photosynthesis, cell integrity, reactive oxygen species scavengers' activity, and osmoregulation of two different species of citrus-the pomelo and the mandarin 'Tankan'-relative to their measured ' L.
