“…In addition, Free-living nematodes can improve soil health, nutrient cycling and even control pests [ 1 ]. Thus, understanding and characterizing the biodiversity of free-living nematodes and their associated bacterial communities in crop ecosystems is crucial for developing sustainable agriculture practices [ 2 – 5 ].…”

“…The intricate and complex network of soil microbial communities plays a vital role in maintaining a healthy ecosystem. These communities are responsible for various ecosystem services such as recycling nutrients, sequestering carbon, retaining water, and promoting plant growth and defense [ 5 ]. By delving deeper into the interactions between plants, nematodes, and microbes in both natural and agricultural ecosystems, we can develop innovative biotechnological tools to manage soil fertility and achieve a high-yield food production system [ 10 , 11 ].…”

The productivity of agricultural ecosystems is heavily influenced by soil-dwelling organisms. To optimize agricultural practices and management, it is critical to know the composition, abundance, and interactions of soil microorganisms. Our study focused on Acrobeles complexus nematodes collected from tomato fields in South Africa and analyzed their associated bacterial communities utilizing metabarcoding analysis. Our findings revealed that A. complexus forms associations with a wide range of bacterial species. Among the most abundant species identified, we found Dechloromonas sp., a bacterial species commonly found in aquatic sediments, Acidovorax temperans, a bacterial species commonly found in activated sludge, and Lactobacillus ruminis, a commensal motile lactic acid bacterium that inhabits the intestinal tracts of humans and animals. Through principal component analysis (PCA), we found that the abundance of A. complexus in the soil is negatively correlated with clay content (r = -0.990) and soil phosphate levels (r = -0.969) and positively correlated with soil sand content (r = 0.763). This study sheds light on the bacterial species associated to free-living nematodes in tomato crops in South Africa and highlights the occurrence of various potentially damaging and beneficial nematode-associated bacteria, which can in turn, impact soil health and tomato production.

The literature review focuses on a comprehensive analysis of scientific research aimed at studying the interaction of phytoparasitic nematodes with energy crops such as Miscanthus, Jerusalem artichoke, and paulownia, as well as examining the factors influencing the spread of these nematodes in cultivation systems of three biofuel crops: giant Miscanthus, velvetleaf, and Jerusalem artichoke. The research is grounded in analyzing the interaction between nematodes and the yield of these crops, along with the potential positive impact of nematode communities from different trophic groups on soil quality and phytoremediation. Special attention is given to phytoparasitic nematodes, which are among the most widespread soil pests of plants. Considering the interaction between nematodes and energy crops is crucial for developing resilient and efficient cultivation systems that ensure high yields and preserve the biodiversity of soil ecosystems.The research concludes that phytoparasitic nematodes have a significant negative impact on the cultivation of energy crops, particularly giant miscanthus. However, certain climatic, chemical, and physical conditions are conducive to the formation of nematode communities that can positively affect soil quality and maintain its fertility. The review provides an overview of three energy crops for biofuel production (giant Miscanthus, velvetleaf, and Jerusalem artichoke), highlighting the nematode pests associated with each of these crops, which have been found in the rhizosphere of plants over many years of published research. Attention is also given to the negative impact of phytoparasitic nematodes on the cultivation of energy crops, especially Miscanthus. However, it has been observed that certain climatic, chemical, and physical conditions favor the formation of nematode communities that can positively influence soil quality and maintain its fertility. This work is significant for the development of strategies to manage the population levels of various trophic levels of nematodes, especially phytoparasitic ones, particularly in the context of cultivating promising energy crops for biofuel production. Additionally, the review describes the important influence of phytoremediation on the population of nematode communities in the soil. The obtained results can serve as a basis for further research in this field and the implementation of effective methods to preserve soil fertility and increase the productivity of energy crops. Furthermore, the findings of this literature review can contribute to the development of environmentally sustainable methods for cultivating energy crops, thereby aiding in the conservation of natural resources and reducing the impact of agricultural activities on the environment.
