Potential Impact of Global Warming on Virus Propagation in Infected Plants and Agricultural Productivity

Abstract

The increasing pace of global warming and climate instability will challenge the management of pests and diseases of cultivated plants. Several reports have shown that increases in environmental temperature can enhance the cell-to-cell and systemic propagation of viruses within their infected hosts. These observations suggest that earlier and longer periods of warmer weather may cause important changes in the interaction between viruses and their host’s plants, thus posing risks of new viral diseases and outbreaks in agriculture and the wild. As viruses target plasmodesmata (PD) for cell-to-cell spread, these cell wall pores may play yet unknown roles in the temperature-sensitive regulation of intercellular communication and virus infection. Understanding the temperature-sensitive mechanisms in plant-virus interactions will provide important knowledge for protecting crops against diseases in a warmer climate.

R-BPMV-Mediated Resistance to Bean pod mottle virus in Phaseolus vulgaris L. Is Heat-Stable but Elevated Temperatures Boost Viral Infection in Susceptible Genotypes

“…Other putative mechanisms of temperature sensitivity have been proposed such as homeostasis of R-interacting chaperons, reduced R protein amounts resulting in a lower R activity, and deregulation of nucleo-cytoplasmic localization of R proteins (reviewed in [ 18 ]). More recently, the implication of the methionine cycle [ 72 ] and deregulation of the intercellular communication via plasmodesmata [ 73 ] have also been supposed to influence virus spread within their hosts.…”

“…Global warming leads to rising temperatures, which alter plant–virus interactions [ 73 ], potentially inducing yield losses and decreasing quality of crop productions [ 107 ]. It is therefore timely to study the effect of elevated temperatures on plant responses to virus infections.…”

Emerging Strategies Mold Plasticity of Vegetable Plants in Response to High Temperature Stress

“…Higher ambient temperatures can promote communication between viruses and infected hosts, thus affecting plant growth and agricultural productivity [ 55 ]. More generally, the high temperatures and humidity of the surrounding environment can induce bacterial disease in the roots of plants, which greatly reduces production.…”

Environmental degradation effect on agricultural development: an aggregate and a sectoral evidence of carbon dioxide emissions from Ghana

“…In spite of these efforts and attempts, growth in agricultural productivity in Ghana remains low (Food and Agricultural Organization (FAO), 2015;Ghana Statistical Service (GSS), 2016;Abdul-Rahaman et al, 2021;Sekyi et al, 2021;Ali et al, 2021). Among other factors, the slow growth in agricultural productivity is attributed to environmental degradation such as poor soil quality, nutrient depletion and climate change (Salvo et al, 2013;Mendelsohn, 2008;Amari et al, 2021;Das et al, 2021). For instance, changes in climate affect crop and livestock production, hydrological balance, input supplies and other components of the agricultural system.…”
