Summary: The study showed that vermicomposts from different plant residues sources can significantly promote the growth of tomato plants infected with root-knot nematodes while effectively controlling the nematode infection. This type of vermicompost serves not only as a bio-organic fertilizer but also as an effective bio-controlling treatment for root-knot nematodes, with no negative impact on the environment.

Summary: The root-knot nematode Meloidogyne incognita adapts rapidly to unfavorable conditions through epigenetic mechanisms, impacting gene expression and sharing similar epigenetic signatures with the model nematode Caenorhabditis elegans. The H3K4me3 histone modification is strongly correlated with high expression of genes during specific developmental stages, providing insights into the dynamic regulation of parasitism genes.

Summary: In this study, Burkholderia sp. JB-2 strain isolated from rhizosphere soil in South Korea was evaluated for its nematicidal and plant growth-promoting effects. The cell-free filtrates of JB-2 showed high nematicidal activity against Meloidogyne incognita and a broad spectrum of activity against other plant parasitic nematodes. Moreover, the cell-free filtrates efficiently controlled nematode populations in soil and promoted the growth of tomato plants.

Summary: Plant-parasitic nematodes (PPNs) are a major threat to global food security and cause crop losses amounting to over USD 150 billion worldwide. This review provides a comprehensive overview of the strategies used to understand the morpho-physiological and molecular events during root-knot nematode (RKN) parasitism. It highlights the recent advancements in transcriptomics, proteomics, metabolomics, and genetic engineering techniques that contribute to understanding plant-nematode interactions and enhancing plant resistance against RKNs.

Summary: Fungal volatile organic compounds (VOCs), particularly 1-Octen-3-ol, are highly toxic to root-knot nematodes and show potential as ecofriendly alternatives to synthetic nematicides. Exposure to 1-Octen-3-ol and 3-Octanone resulted in high mortality rates of the nematodes, with 1-Octen-3-ol exhibiting greater nematicidal activity than 3-Octanone.

Summary: The study found that the level of Meloidogyne javanica inoculum significantly affected soybean growth, grain production, yield, composition, and antioxidant capacity. Plants free of nematodes showed lower vegetative growth and higher yield than nematode-infected plants. The content of various nutrients and antioxidants in soybean grains changed with the increasing nematode inoculum levels.

Summary: This article highlights recent advances in understanding the molecular dialogue between plant-parasitic nematodes (PPNs) and plants at the cellular level. It discusses the roles of plant receptors in PPN perception and manipulation of immune or developmental pathways, as well as how PPNs target these receptors to manipulate their hosts. Additionally, the importance of the plant secretory pathway in PPN infection and resistance is emphasized.

Summary: In this study, the classification of MAP3K genes in plants was conducted and the members and basic characteristics of each subfamily of MAP3K were briefly described. Additionally, the roles of plant MAP3Ks in regulating plant growth and development and in response to stress (abiotic and biotic) were detailed. Furthermore, the involvement of MAP3Ks in plant hormone signaling pathways was briefly introduced, and future research focuses were discussed.

Summary: In this study, vermicomposting of Pleurotus eryngii spent mushroom substrate (SMS) with cow dung as amendment was investigated. It was found that the combination of 65% SMS and 35% cow dung was the most suitable for vermicomposting, resulting in the highest vermicompost production and earthworm biomass increment. Vermicompost also showed significant control efficiency against nematode disease, which was attributed to the enhancement of nematode-trapping fungi species diversity and defense response enzymes in tobacco plants. This study establishes a sustainable avenue for SMS disposal and a practical manner for controlling pathogens.

Summary: The study reveals that soybean lines expressing the Bacillus thuringiensis protein Cy14Ab offer significant protection against soybean cyst nematode (SCN) in both greenhouse and field trials, showing promising potential for controlling plant-parasitic nematodes (PPNs). The mechanism of action involves damaging the nematodes' intestines, similar to how Cry proteins control insects, resulting in a reduction in cyst numbers and egg counts in transgenic soybean plants expressing Cry14Ab.

Summary: This study aimed to identify suitable reference genes for mulberry under different biotic stresses and concluded that different genes are preferred as reference genes during different stresses. This finding contributes to the precise quantification of target genes and unraveling disease resistance mechanisms in mulberry.

Summary: The study examines the impact of root-knot nematode (RKN) and drought stress (DS) on cotton plants. Results show that RKN stress can be detected as early as 10 days after infestation, and RKN, DS, and DS + RKN can be detected with an accuracy of over 98% using specific wavelength bands. Different cotton genotypes showed varied responses to the stresses, with hyperspectral sensor data being able to distinguish RKN-infected plants from drought-stressed plants.
