“…Root-knot nematodes (RKNs) are recognized as major agricultural pathogens, causing expressive losses in many crops (Jones et al, 2013). Among several species that parasitize coffee plants, Meloidogyne paranaensis (Carneiro et al, 1996) is especially important, hindering plant growth and causing losses of approximately 35% in yield (Lopez-Lima et al, 2015). The damage can be even higher depending on the level of attack and on the genetic variability within nematode population (Santos et al, 2018).…”

Resistance of Conilon coffee cultivar Vitoria Incaper 8142 to Meloidogyne paranaensis under field conditions

Meloidogyne paranaensis is responsible for considerable losses in coffee production. Because of the distribution of this species in the main Coffea arabica producing regions, there is a need for management practices to ensure the sustainability of coffee production. In this work, we evaluated the agronomic performance of resistant clones of the Conilon coffee cultivar Vitoria Incaper 8142 in areas infested by M. paranaensis in the west region of Minas Gerais, Brazil. Clones 2V, 3V, and 6V presented the lowest number of nematodes per gram of roots and were considered resistant to M. paranaensis. All other clones were considered tolerant to this nematode, and one had good vegetative growth but allowed nematode reproduction. Clones of Vitoria Incaper 8142 of C. canephora represent an alternative to coffee production in areas infested by M. paranaensis including areas traditionally cultivated with C. arabica.

“…As the infection progresses, the concomitant presence of fungi and bacteria is observed along with nematodes in root tissues, which present more severe symptoms such as hyperplasia with deep and cracked cortical root tissues, having a cork-like appearance, leading to necrosis and atrophy of the root system (Koike et al, 2006;Taher et al, 2017;López-Lima et al, in press;Wolfgang et al, 2019). These symptoms, in the advanced stages of infection, are also commonly known as corky-root disease in coffee (Bertrand et al, 2000;Lopez-Lima et al, 2015;Villain et al, 2018). Consequently, water and nutrient flows are altered, causing significant damage to the plant including chlorosis, defoliation, necrosis of tip branches, and decreased production (Hajji-Hedfi et al, 2018).…”

“…Particularly, severe effects of MDC have been reported in two crops of world importance: tomato (Sasanelli et al, 2008;Ganaie and Khan, 2011;Rizvi et al, 2015;Mwangi et al, 2019) and coffee (Alvarado, 1935;Carneiro et al, 1996;Carneiro et al, 2004;Villain et al, 2013;Lopez-Lima et al, 2015;Monteiro et al, 2016;Villain et al, 2018). In tomato MDC is caused by M. incognita and/or M. enterolobii interacting with F. oxysporum, F. solani, Pyrenochaeta lycopersici, and Rhizoctonia solani (Sasanelli et al, 2008;Ganaie and Khan, 2011;Rizvi et al, 2015;van Bruggen et al, 2016;Mwangi et al, 2019).…”

“…In coffee, MDC is caused by the RKN Meloidogyne paranaensis or M. arabicida interacting with phytopathogenic fungi such as Fusarium oxysporum and F. solani (Bertrand et al, 2000;López-Lima et al, in press). In Mexico, Brazil and Guatemala, M. paranaensis is the RKN responsible for MDC, affecting both Arabica and Robusta crops (Carneiro et al, 1996;Carneiro et al, 2004;Villain et al, 2013;Lopez-Lima et al, 2015;Villain et al, 2018).…”

The Meloidogyne-based disease complexes (MDCs) are caused by the interaction of different root-knot nematode species and phytopathogenic fungi. These complexes are devastating several important crops worldwide including tomato and coffee. Despite their relevance, little is known about the role of the bacterial communities in the MDCs. In this study 16s rDNA gene sequencing was used to analyze the bacterial microbiome associated with healthy and infested roots, as well with females and eggs of Meloidogyne enterolobii and M. paranaensis, the causal agents of MDC in tomato and coffee, respectively. Each MDC pathosystems displayed a specific taxonomic diversity and relative abundances constituting a very complex system. The main bacterial drivers of the MDC infection process were identified for both crops at order level. While corky-root coffee samples presented an enrichment of Bacillales and Burkholderiales, the corckyroot tomato samples presented an enrichment on Saprospirales, Chthoniobacterales, Alteromonadales, and Xanthomonadales. At genus level, Nocardia was common to both systems, and it could be related to the development of tumor symptoms by altering both nematode and plant systems. Furthermore, we predicted the healthy metabolic profile of the roots microbiome and a shift that may result in an increment of activity of central metabolism and the presence of pathogenic genes in both crops.

Plants of Coffea arabica Icatu IAC 925 germplasm show resistance to Meloidogyne paranaensis under field conditions, but with variable rates of segregation. One mother plant, IAC 3, of Icatu IAC 925 was evaluated under controlled conditions through the reaction of its clones, obtained by somatic embryogenesis. Reproduction of nematodes in clones were compared with an open-pollinated progeny from the same mother plant, C. arabica cultivar Mundo Novo IAC 515-20, susceptible to nematodes, and Clone IAC 1, also susceptible and obtained by somatic embryogenesis. Open-pollinated progeny showed segregation to resistance and was classified as susceptible according to the reproduction factor. The average number of nematodes (eggs and J2) per gram of roots in clones was eight fold lower than that of open-pollinated progeny,and 51 fold lower than Mundo Novo IAC 515-20. Based on Seinhorst model, IAC 3 clone showed a tolerance limit of 7.7 nematodes per cm 3 of soil, while in Mundo Novo the tolerance limit was 3.9 nematodes per cm 3 of soil. These results revealed that clonal Arabica coffee nematoderesistant trees represent an alternative to the time consuming and expensive process inherent to conventional breeding strategies.
