Special Issue Information

Dear Colleagues,

Biotic and abiotic stresses limit improvements in the variety and cultivation regulation of crops such as rice, corn, sorghum, wheat, cotton, rape, peanut, soybean, sugarcane and beet, and thus seriously restrict the corresponding industrial developments. However, the response of crops to these stresses remains unclear. It is therefore crucial to focus our research on crop stress biology and molecular breeding through genetic, genomics, molecular biology and other approaches. Current studies in this field seek to reveal the biological basis and processes of important crop traits, including genomics, genes and gene networks; to elucidate the signal transduction pathway of crop stress responses and their interaction with corresponding stress factors; to elaborate upon the adaptation mechanisms of crops in response to their environment (stress); and to discover and identify the key genes and interacting proteins that regulate the formation of traits or adapt to the environment. The exploration of these areas will no doubt reveal gene elements or targets that can be utilized for the genetic improvement of important agronomic traits and assist in enhancing crop characteristics or even creating novel germplasms.

This Special Issue, entitled “Crop Stress Biology and Molecular Breeding: 5th Edition”, welcomes original research and review papers that present biological process analyses of important crop traits, crop gene cloning and functional identification, the screening of linkage markers for crop target traits, and all other related processes. We also welcome the submission of papers that detail the bioinformatics tools and databases used for research regarding crop stress biology and molecular breeding.

This Special Issue is supervised by Prof. Dr. Youxiong Que and assisted by our Topical Advisory Panel Member Dr. Qibin Wu (National Key Laboratory for Tropical Crop Breeding, Institute of Tropical Bioscience and Biotechnology, Chinese Academy of Tropical Agricultural Sciences, Sanya/Haikou, 572024/571737, China).

Pathogens deploy various molecular mechanisms to overcome host defenses, among which glycoside hydrolases (GHs) play a critical role as virulence factors. Understanding the functional roles of these enzymes is essential for uncovering pathogen–host interactions and developing strategies for disease management. Fusarium wilt has occurred in the main Piper nigrum cultivation regions, which seriously affects the yield and quality of P. nigrum. Here, we identified and characterized FsGH28c, a GH28 family member in Fusarium solani. Its expression was significantly upregulated during the infection of black pepper (Piper nigrum) roots by F. solani cv. WN-1, indicating its potential role in pathogenicity. FsGH28c elicited cell death in Nicotiana benthamiana and modulated the expression of genes related to pathogenesis. FsGH28c exerts a positive influence on the pathogenicity of F. solani. The knockout of FsGH28c mutant strains markedly attenuated F. solani ’s virulence in black pepper plants. The knockout mutant strains decrease the ability of F. solani to utilize carbon sources. The FsGH28c deletion did not affect mycelial growth on PDA but did impact spore development. We identified a U-box protein, PnPUB35, interacting with FsGH28c using yeast two-hybrid and bimolecular fluorescence complementation assays. PnPUB35 conferred enhanced resistance to F. solani in black pepper through positive regulation. These findings suggest that FsGH28c may function as a virulence factor by modulating host immune responses through its interaction with PnPUB35. Full article
