Special Issue Information

Dear Colleagues,

The photosynthetic capacity of plants to generate much of their own energy and resources makes them attractive targets to many microbes. The complex interplay between plants and beneficial and harmful microbes has evolved ever since they first appeared on land and shaped them at the genomic and phenotypic levels. A central goal of studying plant–microbe interaction is to understand how plant hosts and microbes communicate and/or manipulate each other to promote their own fitness in an positive or stressed ecosystem. Such research focuses include the plants’ innate immune system, microbial pathogenesis, and synergistic interactions. The advancement of biotechnological tools in fields of genomics, microscopes, biochemistry, and computational biology has revolutionized the study of plant–microbe interaction and fostered new insights and central concepts toward understanding the underlying molecular mechanisms.

Led by Prof. Dr. Yangyong Zhang and assisted by our Topical Advisory Panel Member, Dr. Wei Zhang (Institute for Integrative Genome Biology, University of California Riverside, 2024 Keen Hall, 3401 Watkins Dr, Riverside, CA 92521, USA), this Special Issue is devoted to covering a range of recent advances in natural and agricultural plant–microbe interaction systems using cutting-edge approaches. We welcome all relevant original research, reviews, methods, and opinion articles that aim to propel plant–microbe biology research and applications forward.

Verticillium dahliae is a soil-borne phytopathogenic fungus causing destructive Verticillium wilt disease that greatly threats cotton production worldwide. The mechanism of cotton resistance to Verticillium wilt is very complex and requires further research. In this study, RNA-sequencing was used to investigate the defense responses of cotton leaves using varieties resistant (Zhongzhimian 2, or Z2) or susceptible (Xinluzao 7, or X7) to V. dahliae. The leaf samples were collected at 48 and 72 hpi (hours post infection) from the two varieties infected by V. dahliae (strain Vd991) or treated by water. Compared to X7, Z2 had less genes responsive to V. dahliae infection at 72 hpi and had no DEGs (differentially expressed genes) at 48 hpi. WGCNA (Weighted Gene Co-Expression Network Analysis) revealed seven key gene modules which were responsible for the resistance of Z2 and susceptibility of X7. KEGG (Kyoto Encyclopedia of Genes and Genomes) analysis of these modules found that several reported disease resistance pathways were found to be up-regulated in Z2, with some of those pathways down-regulated in X7. Unexpectedly, several photosynthesis-related pathways were significantly up-regulated in the leaves of X7 infected by V. dahliae, leading to different profiles of glucose content, which was significantly decreased at 72 hpi and 48 hpi in X7 and Z2, respectively. These results suggest that the leaves of resistant varieties have a slower and different response to V. dahliae compared to those of the susceptible variety, as well as that the translocation of sugars produced by photosynthesis in cotton leaves might vary between the two varieties. Additionally, several HUB genes regulating disease response were identified, including NDR1/HIN1-like protein 12, DELLA protein, cytochrome P450 family protein and LRR receptor-like serine/threonine-protein kinase genes, which have been reported to be related to disease resistance in other plants, which might serve as potential candidates for breeding cotton disease resistance.

Bananas (Musa spp.) are among the most important fruit and staple food crops globally, holding a significant strategic position in food security in tropical and subtropical regions. However, the industry is grappling with a significant threat from Fusarium wilt, a disease incited by Fusarium oxysporum f. sp. cubense (Foc). In this study, we explored the potential of Piriformospora indica (Pi), a mycorrhizal fungus renowned for bolstering plant resilience and nutrient assimilation, to fortify bananas against this devastating disease. Through a meticulous comparative analysis of mRNA and miRNA expression in control, Foc-inoculated, Pi-colonized, and Pi-colonized followed by Foc-inoculated plants via transcriptome and sRNAome, we uncovered a significant enrichment of differentially expressed genes (DEGs) and DE miRNAs in pathways associated with plant growth and development, glutathione metabolism, and stress response. Our findings suggest that P. indica plays a pivotal role in bolstering banana resistance to Foc. We propose that P. indica modulates the expression of key genes, such as glutathione S-transferase (GST), and transcription factors (TFs), including TCP, through miRNAs, thus augmenting the plant’s defensive capabilities. This study offers novel perspectives on harnessing P. indica for the management of banana wilt disease. Full article
