“…Plants are often more prone to different biotic and abiotic stresses owing to their sessile nature, and constant exposure to an unpredictable environment leading to extreme loss to crop productivity [ 52 ]. The overexpression, up- or down-regulation, or knock-in of transcribed miRNA gene sequences has confirmed the involvement of miRNAs in biotic stress responses in different plant species [ 53 ].…”

“…Overexpression of miR393 represses auxin signalling, enhancing bacterial resistance, suggesting auxin signalling plays a vital role in plant-induced immune response [ 58 , 59 ]. The complementary strand miR393 has also been reported to play a role in antibacterial immunity by negatively regulating the expression of MEMB12 (SNARE), a protein involved in membrane fusion, thereby promoting the exocytosis of pathogenesis-related protein (PR1) [ 52 ]. Natarajan et al [ 60 ] demonstrated that miR160 plays a crucial role in local defence and systemic acquired resistance (SAR) responses by regulating targets of auxin response factor ( StARF10) and MAP kinase ( StMAPK9 ) during the interaction between potato and P. infestans .…”

Recent advances and potential applications of cross-kingdom movement of miRNAs in modulating plant’s disease response

In the recent past, cross-kingdom movement of miRNAs, small (20–25 bases), and endogenous regulatory RNA molecules has emerged as one of the major research areas to understand the potential implications in modulating the plant’s biotic stress response. The current review discussed the recent developments in the mechanism of cross-kingdom movement (long and short distance) and critical cross-talk between host’s miRNAs in regulating gene function in bacteria, fungi, viruses, insects, and nematodes, and vice-versa during host-pathogen interaction and their potential implications in crop protection. Moreover, cross-kingdom movement during symbiotic interaction, the emerging role of plant’s miRNAs in modulating animal’s gene function, and feasibility of spray-induced gene silencing (SIGS) in combating biotic stresses in plants are also critically evaluated. The current review article analysed the horizontal transfer of miRNAs among plants, animals, and microbes that regulates gene expression in the host or pathogenic organisms, contributing to crop protection. Further, it highlighted the challenges and opportunities to harness the full potential of this emerging approach to mitigate biotic stress efficiently.

“…In the recent past, miRNAs regulated by various stress conditions were identified in plants, which include lack of nutrients [ 86 ], drought [ 87 ], low temperatures [ 88 ], salinity [ 89 ], and pathogen infection [ 90 ], suggesting that miRNAs are regulated in various ways in response to environmental stress. Jones-Rhoades and Bartel revealed that, in Arabidopsis , miR395 levels are increased in sulfate starvation conditions [ 91 ], which suggests that miRNAs are not only synthesized through developmental processes but also due to environmental factors.…”

The Critical Role of Small RNAs in Regulating Plant Innate Immunity

et al. 2021

Plants, due to their sessile nature, have an innate immune system that helps them to defend against different pathogen infections. The defense response of plants is composed of a highly regulated and complex molecular network, involving the extensive reprogramming of gene expression during the presence of pathogenic molecular signatures. Plants attain proper defense against pathogens through the transcriptional regulation of genes encoding defense regulatory proteins and hormone signaling pathways. Small RNAs are emerging as versatile regulators of plant development and act in different tiers of plant immunity, including pathogen-triggered immunity (PTI) and effector-triggered immunity (ETI). The versatile regulatory functions of small RNAs in plant growth and development and response to biotic and abiotic stresses have been widely studied in recent years. However, available information regarding the contribution of small RNAs in plant immunity against pathogens is more limited. This review article will focus on the role of small RNAs in innate immunity in plants.

Background Bacterial wilt is the most devastating disease in ginger caused by Ralstonia solanacearum. Even though ginger (Zingiber officinale) and mango ginger (Curcuma amada) are from the same family Zingiberaceae, the latter is resistant to R. solanacearum infection. MicroRNAs have been identified in many crops which regulates plant-pathogen interaction, either through silencing genes or by blocking mRNA translation. However, miRNA’s vital role and its targets in mango ginger in protecting bacterial wilt is not yet studied extensively. In the present study, using the “psRNATarget” server, we analyzed available ginger (susceptible) and mango ginger (resistant) transcriptome to delineate and compare the microRNAs (miRNA) and their target genes (miRTGs). Results A total of 4736 and 4485 differential expressed miRTGs (DEmiRTGs) were identified in ginger and mango ginger, respectively, in response to R. solanacearum. Functional annotation results showed that mango ginger had higher enrichment than ginger in top enriched GO terms. Among the DEmiRTGs, 2105 were common in ginger and mango ginger. However, 2337 miRTGs were expressed only in mango ginger which includes 62 defence related and upregulated miRTGs. We also identified 213 miRTGs upregulated in mango ginger but downregulated in ginger, out of which 23 DEmiRTGS were defence response related. We selected nine miRNA/miRTGs pairs from the data set of common miRTGs of ginger and mango ginger and validated using qPCR. Conclusions Our data covered the expression information of 9221 miRTGs. We identified nine miRNA/miRTGs key candidate pairs in response to R. solanacearum infection in ginger. This is the first report of the integrated analysis of miRTGs and miRNAs in response to R. solanacearum infection among ginger species. This study is expected to deliver several insights in understanding the miRNA regulatory network in ginger and mango ginger response to bacterial wilt.
