Special Issue Information

Dear Colleagues,

As global climate change continues, wheat fungal diseases are becoming more frequent and severe. Fungal diseases like Fusarium head blight, stripe rust, and powdery mildew are causing devastation in major wheat-producing regions. Researching and understanding the pathogenic mechanisms of these fungal diseases and the functioning of the wheat immune system can help us find more effective prevention and control strategies, thereby increasing wheat yields and ensuring food security.

We aim to report a collection of the latest research, methods, and perspectives in this field. We hope that this Special Issue can facilitate communications among researchers. These exchanges will contribute to the formation of new research ideas.

Recent studies have demonstrated that we can utilize second- and third-generation sequencing technologies to better understand the evolution of fungal diseases. The genetic diversity of fungi can be studied more effectively. The development of high-throughput sequencing technologies has opened up new opportunities for studying issues such as fungal transmission and virulence dynamics. Additionally, the publication of wheat genomes and the release of pan-genomic data have accelerated the cloning and functional research of wheat disease resistance genes. We are now able to more efficiently decipher the genetic mechanisms of disease-resistant cultivars. Population genetics tools have also been widely used in the identification of avirulence genes.

Research articles, short communications, and reviews are all welcome.

Glutaredoxins (GRXs) are widely distributed oxidoreductase enzymes that play important roles in plant growth, development, and responses to various stresses. In this study, bioinformatics methods were used to identify and analyze the wheat GRX gene family and predict their properties and potential functions. RNA-seq and RT-qPCR expression analyses were used to investigate their regulatory functions under hormone treatment and fungal diseases. In this study, 86 GRX genes were identified in wheat and classified into CC-type, CGFS-type, and CPYC-type categories with no TaGRX located on chromosome 4B. The results show that TaGRXs regulate wheat transcriptional responses and have an integrative role in biotic and abiotic stress responses. TaGRXs are involved in wheat responses to Fusarium graminearum, Puccinia striiformis, and Erysiphe graminis diseases. TaGRX73-7D, TaGRX20-3A, and TaGRX29-3B play a negative regulatory role in E. graminis infection but a positive regulatory role in F. graminearum and P. striiformis infection. These TaGRXs play potential regulatory functions in wheat responses to the plant hormones and signaling molecules, including IAA, ABA, H2O2, and SA. The findings of this study lay the groundwork for further investigation of the functions of wheat GRX genes and their potential use as candidate genes for molecular breeding of stress-resistant wheat varieties.
