“…TFs enriched among the DEGs were analyzed using the Plant Transcription Factor Database (http://planttfdb.cbi.pku.edu.cn/, accessed on 3 February 2022). The DEGs from resistant Kufri Swarna included genes for 23 TF families, mainly including bHLH (10), AP2/ERF-ERF (9), MYB (7), and WRKY (9) TFs. These TFs, playing an important role in disease resistance, were highly upregulated in resistant Kufri Swarna versus susceptible Kufri Jyoti (Figure 7A).…”

“…Plant R genes encode proteins that initiate pathways leading to biotic-stress-related disease resistance in plants. Overall, 32 R genes were upregulated in resistant Kufri Swarna in response to PCN infestation (Figure 7B); these included KIN (10), RLK (7), LECRK (5), RLP (3), LEC (2), N (2), CL (1), LYK (1), and T (1). Their expression levels are presented in Figure 7B.…”

“…Infestation by nematodes severely affects the transportation of water and nutrients from roots due to vascular tissue damage, as well as the quality and quantity of the crop. Moreover, the feeding site (i.e., syncytium) formed by the PCN is metabolically active, acts as a "nutrient sink", and attracts nutrients produced by plants [10]. In other words, the plant spends major portions of its energy supporting the PCN at the cost of itself, which results in heavy yield losses of up to 80% [11,12].…”

“…Soil treatment with nematicides is generally not recommended because of the severe health risks to humans, animals, and the environment [17]. To avoid this situation, eco-friendly approaches, such as using resistant varieties, cultural and physical control, and biocontrol agents, etc., are acceptable [10]. However, cultural, physical, and biological control are not efficient because of the several survival adaptations of PCNs, such as a hard protective cyst coat, extended survival in the egg stage for more than two decades, diapause in juveniles, etc.…”

Potato (Solanum tuberosum L.) is an important food crop worldwide, and potato cyst nematodes (PCNs) are among the most serious pests. The identification of disease resistance genes and molecular markers for PCN infestation can aid in crop improvement research programs against PCN infestation. In the present study, we used high-throughput RNA sequencing to investigate the comprehensive resistance mechanisms induced by PCN infestation in the resistant cultivar Kufri Swarna and the susceptible cultivar Kufri Jyoti. PCN infestation induced 791 differentially expressed genes in resistant cultivar Kufri Swarna, comprising 438 upregulated and 353 downregulated genes. In susceptible cultivar Kufri Jyoti, 2225 differentially expressed genes were induced, comprising 1247 upregulated and 978 downregulated genes. We identified several disease resistance genes (KIN) and transcription factors (WRKY, HMG, and MYB) that were upregulated in resistant Kufri Swarna. The differentially expressed genes from several enriched KEGG pathways, including MAPK signaling, contributed to the disease resistance in Kufri Swarna. Functional network analysis showed that several cell wall biogenesis genes were induced in Kufri Swarna in response to infestation. This is the first study to identify underlying resistance mechanisms against PCN and host interaction in Indian potato varieties.

Potato cyst nematodes (PCNs; Globodera spp.) are one of the most difficult pests of potato to manage worldwide. Indiscriminate use of pesticides and their hazardous effects discourage the use of many chemicals for the management of PCNs. As a result, biological control agents and trap crops have received more attention from growers as safer ways to manage PCNs. The biological control agents such as Pochonia chlamydosporia, Purpureocillium lilacinum, Trichoderma spp., Pseudomonas fluorescens, Bacillus spp., Pasteuria spp., and others are recognized as potential candidates for the management of PCNs. Moreover recently, the use of trap crop Solanum sisymbriifolium also showed promise by drastically reducing soil populations of PCNs. Integration of these management strategies along with other practices including identification, conservation, and multiplication of native antagonists, will facilitate efficient management of the PCNs in potato cropping system. Some of the promising research approaches that are being used against PCNs are addressed in this review. © 2022 Society of Chemical Industry.
