The aim of study was to gain a deeper knowledge about local and systemic changes in photosynthetic processes sugar production pepper infected by Obuda virus (ObPV) Pepper mild mottle (PMMoV). PSII efficiency, reflectance, gas exchange were measured 48 and/or 72 h after inoculation (hpi). Sugar accumulation checked hpi 20 d (as response). Inoculation leaves with ObPV led appearance hypersensitive necrotic lesions (incompatible interaction), while PMMoV caused no visible symptoms (compatible interaction). (but not PMMoV) lowered Fv/Fm (from 0.827 0.148 at hpi). Net photosynthesis decreased ObPV-infected leaves. In ObPV-inoculated leaves, the glucose, fructose, glucose-6-phosphate accompanied sucrose, maltoheptose, nystose, trehalose contents. increased contents maltose, raffinose inoculated accummulated upper
