Abstract
Diversity of indigenous arbuscular mycorrhizal fungi in rhizosphere of upland rice (Oryza sativa L.) varieties in Southwest Nigeria
Highlights
Rice (Oryza sativa L.) is one of the world’s most important cereal crops
Given the paucity of information on the natural association of Arbuscular mycorrhizal fungi (AMF) with rice in different production areas of the southwest Nigeria, the aim of this study was to survey fields of different rice cultivars grown across the southwest Nigeria to determine the extent of AMF colonization and community structure in the rhizosphere
Percent AMF root colonization was highest in roots collected from ITA 150 (50%) and lowest in UORW 111 (33.6%)
Summary
Rice (Oryza sativa L.) is one of the world’s most important cereal crops. In Nigeria, rice is a major staple food consume in many households. One of the limiting factors in sustainable utilization of agricultural land for rice production in Nigeria is the declining soil fertility. Arbuscular mycorrhizal fungi (AMF) are important and widespread components of soil microbial communities and agricultural ecosystems forming symbiotic relationships with roots of over 80% terrestrial plants, including many agricultural crops such as rice, soybean etc. (Brundrett and Tedersoo, 2018; de Andrade Júnior et al, 2018) They are generally essential for many important ecosystem functions and processes, including nutrient cycling, plant productivity and sustainability (Van Der Heijden et al, 2015; Souza et al, 2016)
