Special Issue Information

Dear Colleagues,

As plants are constantly plagued by a wide variety of pathogens, ongoing pathogens genomics revolution has highly contributed to disease management applications in phytopathology. The advent of such genomics-based resources coupled with next-generation sequencing (NGS) technologies has improved disease resistance in various crops. Coping with this challenge, these applications are effective and can be routinely adopted for crop protection by unraveling the molecular mechanisms underpinning pathogenesis and resistance, gaining insights into the genetics of pathogen populations on a large scale. Furthermore, transcriptome profiling plays a pivotal role for unraveling the molecular mechanisms during compatible or incompatible plant–pathogen interactions. Thus, RNA-seq technology can effectively decipher the differential expression patterns and the transcriptional immune responses when it comes to resistant and sensitive plant hosts challenged by pathogens.

The aim and scope of this Special Issue are the integration and contribution of genomics or transcriptomics data that would undoubtedly facilitate a comprehensive approach for deciphering various plant–microbe interactions. In the context of this Special Issue, we aim to exchange knowledge on the implementation of pathogens’ genomic approaches, such as pathogen genome-wide association studies and population genomics, or transcriptomic approaches employing RNA-seq differential expression analyses.

In this respect, we are soliciting the submission of any type of research article covering the applications of specific genomics or transcriptomics approaches towards enhancing our understanding of plant–microbe interactions and control of diseases caused by plant pathogens.

The potato is the third largest food crop, and nitrogen fertilizer is important for increasing potato yields; however, the shallow root system of potatoes causes the nitrogen fertilizer utilization rate to be low, which results in waste and environmental pollution, meaning that high nitrogen efficiency breeding is highly significant for potatoes. In the high nitrogen efficiency breeding of potatoes, genes with a nitrogen-deficient response should first be identified, and RNA-seq is an efficient method for identifying nitrogen-deficiency-response genes. In this study, two potato cultivars, Dongnong 322 (DN322) and Dongnong 314 (DN314), were utilized, and two nitrogen fertilizer application rates (N0 and N1) were set for both cultivars. Through the determination of physiological indicators, we identified that DN314 is more sensitive to nitrogen fertilizer, while DN322 is relatively insensitive to nitrogen fertilizer. Samples were taken at the seedling and tuber formation stage. At the seedling stage, DN322 and DN314 had 573 and 150 differentially expressed genes (DEGs), while at the tuber formation stage, they had 59 and 1905 DEGs, respectively. A total of three genes related to a low-nitrogen response were obtained via the combined analysis of differentially expressed genes (DEGs) and weighted correlation network analysis (WGCNA), of which two genes were obtained at the tuber formation stage and one gene in the seedling stage, providing theoretical guidance for the high nitrogen efficiency breeding of potatoes.
