Abstract
MAIN CONCLUSION This review provides valuable insights into plant molecular regulatory mechanisms during fungus attacks, highlighting potential miRNA candidates for future disease management. Plant defense responses to biotic stress involve intricate regulatory mechanisms, including post-transcriptional regulation of genes mediated by microRNAs (miRNAs). These small RNAs play a vital role in the plant's innate immune system, defending against viral, bacterial, and fungal attacks. Among the plant pathogenic fungi, Colletotrichum spp. are notorious for causing anthracnose, a devastating disease affecting economically important crops worldwide. Understanding the molecular machinery underlying the plant immune response to Colletotrichum spp. is crucial for developing tools to reduce production losses. In this comprehensive review, we examine the current understanding of miRNAs associated with plant defense against Colletotrichum spp. We summarize the modulation patterns of miRNAs and their respective target genes. Depending on the function of their targets, miRNAs can either contribute to host resistance or susceptibility. We explore the multifaceted roles of miRNAs during Colletotrichum infection, including their involvement in R-gene-dependent immune system responses, hormone-dependent defense mechanisms, secondary metabolic pathways, methylation regulation, and biosynthesis of other classes of small RNAs. Furthermore, we employ an integrative approach to correlate the identified miRNAs with various strategies and distinct phases of fungal infection. This study provides valuable insights into the current understanding of plant miRNAs and their regulatory mechanisms during fungus attacks.

PLANTS (BASEL, SWITZERLAND) 2023; 12:3070. [PMID: 37687317 PMCID: PMC10490192 DOI: 10.3390/plants12173070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 08/17/2023] [Accepted: 08/26/2023] [Indexed: 09/10/2023]
Abstract
Panax ginseng, renowned for its medicinal properties, relies on adventitious roots and hairy roots as crucial sources for the production of ginsenosides. Despite the widespread utilization of ginseng, investigations into its miRNAs have remained scarce. To address this gap, two samples of ginseng adventitious roots and ginseng hairy roots were collected, and subsequent construction and sequencing of small RNA libraries of ginseng adventitious roots and hairy roots were performed using the Illumina HiSeq X Ten platform. The analysis of the sequencing data unveiled total miRNAs 2432. The miR166 and miR396 were the most highly expressed miRNA families in ginseng. The miRNA expression analysis results were used to validate the qRT-PCR. Target genes of miRNA were predicted and GO function annotation and KEGG pathway analysis were performed on target genes. It was found that miRNAs are mainly involved in synthetic pathways and biological processes in plants, which include metabolic and bioregulatory processes. The plant miRNAs enriched KEGG pathways are associated with some metabolism, especially amino acid metabolism and carbohydrate metabolism. These results provide valuable insights miRNAs and their roles in metabolic processes in ginseng.
