From: The effect of ‘Candidatus Liberibacter asiaticus’ infection on the proteomic profiles and nutritional status of pre-symptomatic and symptomatic grapefruit (Citrus paradisi) plants

Figure 5

The concentrations of macro- and micro-nutrients in leaves of grapefruit plants that were Las-infected or uninfected and pre-symptomatic or symptomatic for HLB. (A) macronutrients calcium, potassium and magnesium; (B) micronutrients iron, manganese, zinc, and copper. UP, uninfected control for pre-symptomatic plants; IP, infected pre-symptomatic plants; US, uninfected control for symptomatic plants; IS, infected symptomatic plants. Two-year old healthy plants were either graft-inoculated with side shoots from PCR-confirmed Las-infected bud sticks or uninoculated and leaf samples were analyzed at three months post-inoculation (for pre-symptomatic plants) or six months post-inoculation (for symptomatic plants). Bars within an elemental group with the same lower case letter are not significantly different from each other (P > 0.05).
