Abstract: Modeling studies have predicted that coffee crop will be endangered by future global warming, but recent reports highlighted that high [CO2] can mitigate heat impacts on coffee. This work aimed at identifying heat protective mechanisms promoted by CO2 in Coffea arabica (cv. Icatu and IPR108) and Coffea canephora cv. Conilon CL153. Plants were grown at 25/20°C (day/night), under 380 or 700 μL CO2 L−1, and then gradually submitted to 31/25, 37/30, and 42/34°C. Relevant heat tolerance up to 37/30°C for both [CO2]… Show more

“…Such repression was only maintained for CAT at severe water stress in Burgos, while their expression was up-regulated in the other genotypes under elevated [CO 2 ] × severe water stress. This could suggest a higher demand for ROS control, which would indicate a limitation to the transfer of electrons through photosystems to drive C assimilation (Martins et al, 2016). Enzyme activity and CAT gene expression have been reported to decrease under elevated [CO 2 ] in wheat, possibly due to the inhibition of photorespiration, while they increased only in response to severe drought (Luna et al, 2005; Xu et al, 2010; Vicente et al, 2015b).…”

“…Notably, coffee production is notable due to the use of family labor, which mostly involves low technology. Such practices have influenced both coffee production and final grain quality, potentially affecting not only producers but also the entire industrial and final consumer market (Martins et al, 2016).…”

“…Soluble sugars are highly sensitive to environmental fluctuations, especially when carbon partitioning between sources and sinks is affected. Interferences between elevated CO 2 and heat integrate metabolic and signaling mechanisms (Ahammed et al, 2015;Hamilton et al, 2008;Li et al, 2015;Martins et al, 2016;Zinta et al, 2014). Variations of sugar levels are sensed by the SnRK1 (Snf1-related protein kinase 1) sensor, which is involved in stress tolerance.…”

“…Moreover, most environmental stresses induce major changes in carbon metabolism (Rosa et al, 2009). eCO 2 can have positive effects on photochemical functioning, through lower rate of PSII inactivation and nonphotochemical quenching (Martins et al, 2016). Metabolic performance is thus improved relatively to normal CO 2 conditions, with the maintenance of positive carbon balance and accumulation of nonstructural carbohydrates, which result from increase in net photosynthesis, inhibition of photorespiration, and more production than utilization of carbohydrates (Song, Yu, & Huang, 2014).…”
