“…Traditionally, genetic architecture of complex traits has been accomplished by scanning recombinant mapping families using a QTL mapping approach. In coffee, QTL have been reported for the incompatibility S locus (Lashermes et al., 1996), pollen viability restoration (Coulibaly et al., 2003), disease resistance (de Almeida et al., 2021), root traits (Achar et al., 2015), fructification time (Akaffou et al., 2003), morphological traits (Michel et al., 2007), and more recently, for yield and quality‐related traits (Leroy et al., 2011). Despite the relevance, QTL studies required either a detailed population pedigree or controlled crosses, restricting the conclusions to a certain genetic background (Comeault et al., 2014).…”

Genomic‐assisted breeding for climate‐smart coffee

Coffee is a universal beverage that drives a multi‐industry market on a global basis. Today, the sustainability of coffee production is threatened by accelerated climate changes. In this work, we propose the implementation of genomic‐assisted breeding for climate‐smart coffee in Coffea canephora. This species is adapted to higher temperatures and is more resilient to biotic and abiotic stresses. After evaluating two populations, over multiple harvests, and under severe drought weather condition, we dissected the genetic architecture of yield, disease resistance, and quality‐related traits. By integrating genome‐wide association studies and diallel analyses, our contribution is four‐fold: (i) we identified a set of molecular markers with major effects associated with disease resistance and post‐harvest traits, while yield and plant architecture presented a polygenic background; (ii) we demonstrated the relevance of nonadditive gene actions and projected hybrid vigor when genotypes from different geographically botanical groups are crossed; (iii) we computed medium‐to‐large heritability values for most of the traits, representing potential for fast genetic progress; and (iv) we provided a first step toward implementing molecular breeding to accelerate improvements in C. canephora. Altogether, this work is a blueprint for how quantitative genetics and genomics can assist coffee breeding and support the supply chain in the face of the current global changes.

“…More recently, resistance to three different H. vastatrix pathotypes in another HDT-derived lineage was shown to be conferred by at least two independent dominant QTLs [91]. These genetic resources opened new possibilities for MAS-driven resistance breeding in coffee, prompting the first reports of successful marker validation and selection of coffee cultivars harboring distinct loci for resistance, not only to CLR, but also to coffee berry disease (CBD) [92,93]. Other promising genomic-driven approaches to improve coffee breeding for durable and broad-spectrum resistance have been studied, such as genomic selection [94], and genomics-assisted exploitation of mutant or impaired susceptibility (S)-genes in the host plant that will lead to ''loss of susceptibility" [95].…”

Coffee is one of the most consumed beverages in the world. It is also one of the most globally traded commodities. Coffee leaf rust (CLR), caused by the biotrophic fungus Hemileia vastatrix, is the most important disease affecting Arabica coffee growing worldwide, leading to significant yield losses if no control measures are applied. A deep understanding of the complex mechanisms involved in coffee-H. vastatrix interactions, such as the pathogen variability and the mechanisms governing plant resistance and susceptibility, is required to breed efficiently for durable resistance and design new approaches for crop protection. Here we summarize our current understanding across multiple areas related to pathogen infection, variability and candidate effectors, breeding for disease resistance, and the various components of the coffee immune system, by reviewing a comprehensive body of research on CLR and the advances recently made. We also update information about the defense responses activated by the application of plant resistance inducers, a promising alternative to fungicides in the control of CLR. Moreover, we identify and discuss future directions for further research.

“…Genetic sources of resistance to coffee leaf rust (CLR), caused by the fungal pathogen Hemileia vastatrix , are today present in most commercial C . arabica coffee cultivars (i.e., Catimores and Sachimores) based on breeding programmes using nine resistance genes called S H 1–9 , from the Timor Hybrid (de Almeida et al, 2021; Sera et al, 2022; Talhinhas et al, 2017; Zambolim, 2016). Wild Ethiopian landraces (i.e., Geisha) also exhibit some level of genetic resistance to CLR (https://varieties.worldcoffeeresearch.org/varieties/geisha).…”

Alternative plant protection strategies for tomorrow's coffee

Around 2 billion cups of coffee are consumed daily, worldwide (Reay, 2019). However, the coffee plant is under threat due to its vulnerability to a plethora of plant pests and diseases, exacerbated by climate change (Avelino, ten Hoopen, et al., 2012;Kumar et al., 2016).In fact, the typical coffee farmer faces a diverse onslaught by an assortment of beetles, bacteria, fungi and nematodes in just one production season (Waller et al., 2007). Traditional chemical pesticides (i.e., insecticides and fungicides) have been a mainstay of the Green Revolution, and thus commonly deployed in coffee production. With more than 470 licensed products approved for use in Brazil alone (Coelho et al., 2019), these agrochemicals are being used as a primary means of management in the onset of pests and diseases across all agricultural sectors including coffee (
