“…Two articles found increased light exposure resulted in increased levels of lipids (Delaroza et al, 2017;Rakocevic et al, 2018) while one article found a decrease in lipids with increased light (dos Santos Scholz et al, 2018). Two articles found an increase in sugar levels with increased light (Somporn et al, 2012;Worku et al, 2018) while two other articles found a decrease in sugar levels with increased light (Somporn et al, 2012;dos Santos Scholz et al, 2018).…”

“…Four articles found a decrease in phenolic metabolites with an increase in light exposure (Somporn et al, 2012;Delaroza et al, 2017;Tolessa et al, 2017;dos Santos Scholz et al, 2018) while three other articles demonstrated an increase in phenolics with increasing light exposure (Somporn et al, 2012;Tolessa et al, 2017;dos Santos Scholz et al, 2018). Several articles found both an increase and a decrease of various phenolic metabolites with increasing light exposure (Somporn et al, 2012;Tolessa et al, 2017;dos Santos Scholz et al, 2018).…”

“…Several articles found both an increase and a decrease of various phenolic metabolites with increasing light exposure (Somporn et al, 2012;Tolessa et al, 2017;dos Santos Scholz et al, 2018). The articles examining the effects of increased light exposure on methylxanthines/alkaloids (n = 3) found an inverse relationship (Delaroza et al, 2017;Tolessa et al, 2017;Rakocevic et al, 2018).…”

“…One article revealed a non-linear relationship between chlorogenic acids and light, with the highest levels of chlorogenic acids being highest in coffee grown in natural shade (>70%) followed by coffee grown under artificial shade of 60, 70, 50%, and lastly under full sun (Somporn et al, 2012). Tolessa et al (2017) and Delaroza et al (2017) found caffeine content decreased with increased light due to less shade from the canopy.…”

Climate Change and Coffee Quality: Systematic Review on the Effects of Environmental and Management Variation on Secondary Metabolites and Sensory Attributes of Coffea arabica and Coffea canephora

et al. 2021

Climate change is impacting crop performance and agricultural systems around the world with implications for farmers and consumers. We carried out a systematic review to synthesize evidence regarding the effects of environmental factors associated with climate change and management conditions associated with climate adaptation on the crop quality of a culturally-relevant perennial crop, coffee (Coffea arabica and Coffea canephora). Seventy-three articles were identified that addressed the study's research question including 42 articles on environmental factors, 20 articles on management conditions, and 11 articles on both. While variation was found between studies, findings highlight that coffee quality is vulnerable to changes in light exposure, altitude, water stress, temperature, carbon dioxide, and nutrient management. Both increases as well as decreases were found in secondary metabolites and sensory attributes that determine coffee quality in response to shifts in environmental and management conditions. The most consistent evidence identified through this systematic review includes the following two trends: (1) increased altitude is associated with improved sensory attributes of coffee and; (2) increased light exposure is associated with decreased sensory attributes of coffee. Research gaps were found regarding the effects of shifts in carbon dioxide, water stress, and temperature on the directionality (increase, decrease, or non-linear) of coffee quality and how this varies with location, elevation, and management conditions. This systematic review further identified the following research needs: (1) long-term studies that examine the interactive effects of multiple environmental factors and management conditions on coffee quality; (2) studies that examine the interaction between sensory attributes and secondary metabolites that determine coffee quality and; (3) studies on the feasibility of various climate-adaptation strategies for mitigating the effects of climate change on coffee quality. Evidence-based innovations are needed to mitigate climate impacts on coffee quality toward enhanced sustainability and resilience of the coffee sector from farm to cup.

Metabolomics, a Powerful Tool for Understanding Plant Abiotic Stress

et al. 2021

Metabolomics is a technology that generates large amounts of data and contributes to obtaining wide and integral explanations of the biochemical state of a living organism. Plants are continuously affected by abiotic stresses such as water scarcity, high temperatures and high salinity, and metabolomics has the potential for elucidating the response-to-stress mechanisms and develop resistance strategies in affected cultivars. This review describes the characteristics of each of the stages of metabolomic studies in plants and the role of metabolomics in the characterization of the response of various plant species to abiotic stresses.
