Root-knot nematodes (RKNs), belonging to the genus Meloidogyne, are plant parasitic with a broad host range, causing substantial economic losses annually. The selection and utilization of novel biological control resources crucial for managing RKNs diseases. This study isolated Candida quercitrusa Cq-C08 from rhizosphere soil, which efficacy against Meloidogyne incognita was investigated through laboratory experiments, pot plot trials, analysis transcriptomic data cucumber roots treated Cq-C08. series experiments confirmed that fermentation broth had lethal rate 100% M. J2s within 12 h exhibited significant repellent effect on nematodes. In tests, strain achieved over 50% significantly promoted (Cucumis sativus, Zhongnong No. 6, China) growth. Inoculation could activate key immune signaling pathways salicylic acid (SA) jasmonic (JA). Split-root tests showed induced resistance by 32.3%.

Biosecurity in agriculture is essential for preventing the introduction and spread of plant-parasitic nematodes (PPNs) which threaten global food security by reducing crop yields facilitating disease spread. These risks are exacerbated increased trade climate change, may alter PPN distribution activity, increasing their impact on agricultural systems. Addressing these challenges vital to maintaining integrity supply chain. This review highlights significant advancements managing PPN-related biosecurity within chain, particularly considering change’s evolving influence. It discusses modes transmission, factors risk infestation, PPNs safety security, traditional emerging approaches detecting pests. Literature suggests that implementing advanced measures could decrease infestation rates up 70%, substantially yield losses bolstering security. Notably, adoption modern detection management techniques, (molecular diagnostics integrated pest management) geospatial surveillance analysis systems (spectral imaging, change-detection analysis) has shown greater effectiveness than methods. innovations offer promising avenues enhancing health securing chain against environmental shifts. The integration strategies crucial, demonstrating potential transform practices sustain productivity face changing climatic conditions. emphasizes importance adopting protect ensure resilience, providing valuable insights stakeholders across sector.

The assembly of the rhizosphere community, even diazotroph is mainly shaped by soil environmental factors (including climate and physiochemical characteristics) plant selection. To better understand driving forces on active overall nitrogen-fixing bacterial community compositions, we characterized communities tobacco collected from three sampling sites with a large geographic scale (> 600 km). results indicate that diversity composition are obviously differed according to sites. Still, no significant difference found between in rootzone samples. Climate variables including mean annual precipitation (MAP) temperature (MAT), characteristics available nitrogen (AN), potassium (AK) pH main affect structures Furthermore, MAP MAT, AN phosphorus (AP), total (TN) organic carbon (OC), AK electrical conductivity (EC) showed similar effects, but independent effect bacteria communities. However, alpha indices higher than samples, differences observed among different Proteobacteria predominant phylum all samples for bacteria.

These contribute more assemblage, contributes community. Our study provides novel knowledge assemble across geographical scale.
