“…The results showed that rapid growth of P. lilacinum mycelium wraps Meloidogyne eggs when in contact. The mycelium then infects and kills the eggs ( Cadioli et al, 2007 ). However, little is known about the molecular mechanisms underlying this parasitic behavior of P. lilacinum toward Meloidogyne eggs, and genetic resources of P. lilacinum are also rare.…”

The egg-pathogenic fungus Purpureocillium lilacinum parasitizes on nematode eggs, and thus, it is used as a good biocontrol agent against plant root-knot nematodes. However, little is known about the transcriptional response of P. lilacinum while infecting nematode eggs. This study presents the whole transcriptome sequencing of P. lilacinum and transcriptome-wide gene expression analysis of P. lilacinum upon infecting the eggs of Meloidogyne incognita compared to non-infecting controls. A transcriptomic library of P. lilacinum was used as reference gene set and six transcriptomic libraries of the non-infecting control and P. lilacinum infecting M. incognita eggs were constructed, respectively, comprising three biological replicates of each. A total of 1,011 differently expressed genes (DEGs) were identified in the infecting samples, including 553 up-regulated and 458 down-regulated genes compared to the non-infecting control samples. Furthermore, functional enrichment analysis exhibited that these DEGs were primarily involved in oxidative phosphorylation, oxidoreductase activity, and metabolic processes. Fifteen DEGs were randomly selected to verify the RNA sequencing results through quantitative real-time polymerase chain reaction (qPCR). The study focused on P. lilacinum genes that were strongly expressed upon infecting M. incognita eggs. These DEGs were primarily involved in detoxification, parasitic behavior, and nutritional utilization. This study contributes significantly to the understanding of the molecular mechanisms underlying the parasitic action of P. lilacinum on nematode eggs and provides a valuable genetic resource for further research on parasitic behavior of P. lilacinum. Notably, this study examined the transcriptomics of P. lilacinum infecting M. incognita eggs at only one time point. Since there were fungi at different stages of the infection process at that time point, the transcriptional profiles are not precisely examining one specific stage in this process.

“…The nematode‐control efficiency of P. lilacinum has already been observed in several studies; however, most of those results concerned the management of root‐knot nematodes (Jatala, ; Khan, Williams, & Nevalainen, , ; Morgan‐Jones, White, & Rodriguez‐Kabana, ; Santiago et al., ). In these cases, the effect was attributed to the ability of the fungus to colonize eggs and sedentary females (Khan et al., , ), including the Pae 10 isolate (Cadioli, Santiago, Hoshino, & Homechin, ), which was evaluated in the current study. On the other hand, studies focusing on the management of migratory nematodes are scarce.…”

The aim of the current study was to assess the activity of Purpureocillium lilacinum and Trichoderma harzianum fungi, either alone or in combination, and the use of a bioactivator to control Pratylenchus brachyurus in soya bean crops. Thus, two experiments were conducted in a greenhouse, and two were conducted in naturally infested fields. Both fungi were efficient in controlling the nematode when they were applied alone, whereas the combination of the two did not improve nematode control. However, the addition of a bioactivator (moss) to the combination of fungi (P. lilacinum + T. harzianum + moss) generally promoted better control of the nematode in the greenhouse, with a reduction in the total abundance of the nematode ranging from 57.1% to 73.75%, and under field conditions, with a reduction ranging from 55.5% to 72.0%. The same treatment increased yield in both field experiments, but the treatment with T. harzianum promoted greater gains in productivity, varying from 11.79% to 20.85%.
