Response of rice genotypes to rice root‐knot nematode (Meloidogyne graminicola) infection under varying temperature regimes

et al. 2022

Rice (Oryza sativa) is a staple food for more than 50% of the world's population and provides 20% of total calories (Fukagawa & Ziska, 2019). Biotic and abiotic stresses are responsible for significant yield losses in rice. Among biotic stressors, nematodes are important limiting factors in both aerobic and direct-seeded rice (Devaraja et al., 2017). The four major nematode species causing significant yield losses to rice are Meloidogyne graminicola, Ditylenchus angustus, Hirshmanniella oryzae and Aphelenchoides besseyi (Bridge & Page, 1982;Pankaj et al., 2010). Among these, the rice root-knot nematode (RRKN), M. graminicola, is a major threat to the rice-wheat

“…Genetic resources are another type of ES produced by macrophytes. For example, genetic studies in cultivated and wild rice species have helped to identify disease resistance mechanisms (Bansal et al, 2020;Hada et al, 2020), with great potential to be used in breeding programs to reduce damage to varieties of rice. From this example, we expect that the same procedure can be employed for other macrophytes used as food by humans.…”

Ecosystem services provided by freshwater macrophytes

Macrophytes are considered key components of aquatic ecosystems and they also provide multiple benefits for humans. In this review, I identified and exemplified 26 types of ecosystem services provided by macrophytes. The most important supporting services provided by these plants are related to nutrient cycling and provisioning of habitat, but macrophytes also participate in water cycling and gases production. The presence of macrophytes and their activity enhance water purification and disease control which are important regulating services. Provisioning services are provided in the form of food at the local and global scale (e.g., rice), fiber, biochemicals, natural medicine and ornamental resources. Cultural services are provided in the form of spiritual and religious artifacts and local knowledge systems of communities which depend on macrophytes for surviving. Other cultural services are associated with educational activities, art inspiration, esthetic values in aquatic gardens and ponds, uses for leisure, recreation and ecotourism. There is evidence that the efficiency of ecosystem functioning, the provision of ecosystem services and ecosystem stability is enhanced by macrophyte diversity. Because macrophyte communities provide important benefits for humans, their conservation and restoration, where necessary, are important for human well-being.

Meloidogyne graminicola—A Threat to Rice Production: Review Update on Distribution, Biology, Identification, and Management

Rice (Oryza sativa L.) is one of the main cultivated crops worldwide and represents a staple food for more than half of the world population. Root-knot nematodes (RKNs), Meloidogyne spp., and particularly M. graminicola, are serious pests of rice, being, probably, the most economically important plant-parasitic nematode in this crop. M. graminicola is an obligate sedentary endoparasite adapted to flooded conditions. Until recently, M. graminicola was present mainly in irrigated rice fields in Asia, parts of the Americas, and South Africa. However, in July 2016, it was found in northern Italy in the Piedmont region and in May 2018 in the Lombardy region in the province of Pavia. Following the first detection in the EPPO region, this pest was included in the EPPO Alert List as its wide host range and ability to survive during long periods in environments with low oxygen content, represent a threat for rice production in the European Union. Considering the impact of this nematode on agriculture, a literature review focusing on M. graminicola distribution, biology, identification, and management was conducted.
