Summary: Significant yield losses in major cereal-growing regions have been caused by cereal cyst nematodes. Identifying natural sources of resistance is important due to concerns about chemical methods. In this study, diverse wheat genotypes were screened for nematode resistance, and genome-wide association analysis identified several significant genetic markers related to nematode resistance. Candidate gene analysis further revealed potential genes involved in disease resistance. These results provide valuable genetic resources for reducing the impact of cereal cyst nematodes on wheat production and developing new control strategies.

Summary: The increased populations of Heterodera avenae in southeastern Idaho are attributed to the planting of susceptible cereal cultivars and the lack of crop rotation. Testing new genotypes and susceptibility assessments of marketed cultivars are necessary to identify high-yield, resistant spring wheat cultivars with tolerance. The results of the experiments showed that the use of aldicarb increased the grain yield of susceptible cultivars, while the resistant variety carrying the Cre5 resistance gene maintained its standard yield.

Summary: CCNs has been found in many provinces in China, and our study collected 821 samples from 16 provinces during 2019-2022 to investigate its distribution. Heterodera avenae was detected in 56.39% of the samples, primarily in Hubei, Henan, Hebei, Shandong, Shanxi, Gansu, Beijing, Tianjin, Inner Mongolia, Ningxia, Xinjiang, Qinghai, Anhui, Shaanxi, and Jiangsu. Genetic analysis revealed significant differences between Chinese populations and populations from other countries.

Summary: Increased populations of H. avenae in southeastern Idaho are caused by susceptible cereal cultivars and lack of crop rotation. We conducted experiments to test the yield of wheat cultivars with resistance to H. avenae and found that aldicarb treatment significantly increased grain yield of susceptible cultivars. Our results suggest that aldicarb can improve wheat grain yield and has potential for research.

Summary: This study provides theoretical support for the origin and spread of H. avenae populations in China and elsewhere in the world. It found that H. avenae in China has high genetic diversity and endemism, with significant evolutionary and genetic differences from populations in other countries. The Yellow River and mechanical harvesters may promote gene exchange among different regions.

Summary: The resistance conferred by the Cre8 locus of wheat prevents cereal cyst nematode feeding sites from reaching and invading root metaxylem vessels, leading to differences in cellular structures and internal changes in the roots between susceptible and resistant wheat plants.

Summary: In this study, a major QTL associated with the resistance to the cereal cyst nematode Heterodera avenae was identified in wheat. The resistant DH lines showed a decrease in the number of nematode juveniles with no presence of J4 stage juveniles compared to the susceptible lines. In addition, the resistant DH lines exhibited higher biological yield, grain yield, and harvest index compared to the known resistant parent over a span of two years. These findings suggest that the selected DH lines are potential pre-breeding materials to introduce novel genetic variations for H. avenae resistance in cultivated wheat.

Summary: This study investigated the effects of five inorganic ion concentrations on the hatching of cereal cyst nematode eggs. The results showed that ZnCl2 and FeCl3 promoted the hatching of induced and natural diapausing eggs, while different concentrations of inorganic ions did not have any effect on white female eggs. These findings provide valuable information for controlling nematode diseases caused by H. avenae using new fertilizers.

Summary: A TaqMan-minor groove binder (TaqMan-MGB) probe-based fluorescence quantitative real-time PCR (qPCR) method was successfully developed for the efficient detection and quantification of H. filipjevi directly from field soils. The method showed high specificity and sensitivity, capable of detecting very low levels of H. filipjevi DNAs.

Summary: The study revealed that the fungal species associated with the cereal cyst nematode H. filipjevi belong to diverse phyla, including Ascomycota, Basidiomycota, and Mucoromycota. Ascomycota represent recent fungal infections, while Basidiomycota indicate the preceding host plants, allowing for the chronological tracing of plant field colonization history.

Summary: The study investigated the resistance situation of indigenous wheat varieties in Turkey against a certain population of cereal cyst nematodes. Some wheat varieties showed high resistance, while barley varieties generally lacked resistance. Various resistance genes were identified in different wheat varieties, but there was no correlation found between any marker and phenotypic resistance.

Summary: The soybean cyst nematode (SCN, Heterodera glycines, HG) is a major pest that causes significant damage to soybean production worldwide by impairing root development. Breeding SCN-resistant cultivars is crucial for maintaining harvests without harming the environment. In this study, 12 soybean cultivars were evaluated for their resistance markers and shown to have resistance against multiple SCN races, indicating their potential as donor parents in breeding programs and their contribution to sustainable agriculture management by reducing SCN field populations.

Summary: Plant-parasitic cyst nematodes deliver effector proteins into root cells to modulate plant defense responses and developmental programs. The Hs2D01 effector interacts with the receptor kinase HAESA and may play a role in sugar beet cyst nematode parasitism.
