“…Although most of the results could be explained by the difference of virus concentration between cultivars, however, it is necessary to do more experiments with different levels of infection in order to confirm this hypothesis (El Aou‐ouad et al ., ; Montero et al ., , ). Differences in virus concentration could explain the great variability of physiological consequences of this biotic stress observed among the studies.…”

Grapevine leafroll disease is one of the most important viral diseases of grapevine (Vitis vinifera) worldwide. Grapevine leafroll-associated virus 3 (GLRaV-3) is the most predominant virus species causing this disease. Therefore, it is important to identify GLRaV-3 effects, especially in plants which do not systematically show visual symptoms. In this study, effects of GLRaV-3 on grapevine physiology were evaluated in asymptomatic plants of Malvasía de Banyalbufar and Cabernet Sauvignon cvs. Absolute virus quantification was performed in order to determine the level of infection of the treatment. The net carbon dioxide (CO 2 ) assimilation (A N ) and electron transport rate (J flux ) were the main parameters affected by the virus. The A N reduction in infected plants was attributed to restrictions in CO 2 diffusion caused by anatomical leaf changes and a reduction of Rubisco activity. Those effects were more evident in Malvasia de Banyalbufar plants. The reduction of A N leads to a decrease in the total oxygen uptake rate by the activity of the cytochrome oxidase pathway, producing slight differences in plant growth. Therefore, even though no symptoms were expressed in the plants, the effects of the virus compromised the plant vital processes, showing the importance of early detection of the virus in order to fight against the infection.Closteroviridae family. In red varieties, symptoms of GLRaV-3 are easily identified, noticeable as dark-red, downward rolling leaves with green veins, but the infection is almost asymptomatic in white varieties. The difficulty in detecting virus can lead to rapid spread of virus-infected material through propagation. Diagnostic methods for the detection of grapevine viruses have been developed over the last few years. These methods include: biological indexing (Habili et al., 1992), enzyme-linked immunosorbent assay (ELISA) (Rowhani, 1992;Frosline et al., 1996;Rowhani et al., 1997) and nucleic acid-based methods, mainly PCR methods (Minafra et al.Grapevine leafroll-associated virus 3 effects on plant physiology R.

“…The allocation of carbohydrate depends upon virus-encoded membrane proteins (MPs) and plasmodesmata (PDs) size expansion. Several workers demonstrated that leafroll virus-3 in grapevine causes a disruption in transport and accumulation of photosynthetic assimilates such as sucrose (Endeshawet et al, 2014;Montero et al, 2016…”

“…In grapevines, measuring the changes in carbon assimilation and respiration during the growing season can provide an understanding of the dynamics of carbon fluxes from different organs and their relationship during vine phenology. Nowadays, the quantitative understanding of how plants gain and allocate their resources would help to make predictions under particular climate change conditions, such as higher temperature (Greer 2017), drought and salinity (Flexas et al 2006), under specific cultural practices (Brunori et al 2016) or under the effect of plant diseases (Montero et al 2016, El Aou-Ouad et al 2018. Plant carbon balance in the field, however, represents important experimental limitations and difficulties because of a large number of factors that interact along plant phenology in natural vegetation and crop systems (Mir as- Avalos et al 2018).…”

Background and Aims Measuring the carbon assimilation and respiration during vine phenology can provide an understanding of the dynamics of carbon fluxes from different organs and their relationship. Most field studies to date do not consider the respiratory losses of different plant organs and their variability under environmental, genetic and phenological changes. The aim of this study was to investigate the effect of genotype and water regime on carbon assimilation, respiration and allocation during vine phenology. Methods and Results Field trials were carried out during 2013 and 2014 to study the effect of genotype and water status on carbon assimilation, respiratory losses from leaves, shoots, fruits and roots during the vine phenological cycle, and on biomass production. Carbon respiration varied during plant phenology and represented a significant proportion of the total vine carbon assimilation. The integrated carbon respiratory loss in leaves, fruits and roots was greater in irrigated vines than in non‐irrigated vines. Tempranillo recorded the highest carbon assimilation, leaf and stem respiration, as well as the highest above‐ground biomass. Garnacha showed a higher root respiration loss and allocated more biomass to the permanent organs. Accumulation of above‐ground biomass was influenced by plant carbon budgets during the growing season. Conclusions Vine phenology, cultivar and plant water status affected carbon assimilation, carbon loss and carbon allocation. Non‐irrigated vines had a higher respiratory carbon loss in respect to the total carbon assimilation by photosynthesis. Above‐ and below‐ground carbon fluxes were coupled during vine phenology. Significance of the Study The present work illustrates the importance of respiratory processes on the carbon balance and the relationship among different carbon balance components during vine phenology.
