Stress resilience in <i>Coffea arabica</i> and <i>Coffea canephora</i> under harsh drought and/or heat conditions: selected genes, proteins, and lipid integrated responses.

ABSTRACT: Climate change has intensified the frequency, severity, and simultaneous incidence of drought and heat events, threatening the sustainability of agricultural systems worldwide. This implies the use of resilient plant genotypes able to activate defense mechanisms and overcome stress damage. We examined the leaf transcriptomic, proteomic, and membrane lipid responses in two cultivars of the main coffee-producing species-Coffea arabica L. cv. Icatu and Coffea canephora Pierre ex A. Froehner cv. Conilon Clone 153 (CL153-subjected to single and combined exposure to severe water deficit (SWD) and heat (up to 42°C/30°C, day/night). Well-watered (WW) plants maintained under adequate temperature (25°C/20°C) were gradually exposed to SWD and afterward to a slow temperature increase up
