“…The mechanism of action of sRNA at target sites involves transcriptional and post-transcriptional gene silencing through DNA methylation, RNA slicing, histone modification, and translational repression (Tang et al 2022 ; Patel et al 2020 ). Additionally, they exhibit diverse regulatory patterns in response to varying stress conditions, with upregulation observed in positive regulators and downregulation in negative stress regulators (Sun et al 2021a ).…”

Main conclusion Plant Biomarkers are objective indicators of a plant’s cellular state in response to abiotic and biotic stress factors. They can be explored in crop breeding and engineering to produce stress-tolerant crop species. Abstract Global food production safely and sustainably remains a top priority to feed the ever-growing human population, expected to reach 10 billion by 2050. However, abiotic and biotic stress factors negatively impact food production systems, causing between 70 and 100% reduction in crop yield. Understanding the plant stress responses is critical for developing novel crops that can adapt better to various adverse environmental conditions. Using plant biomarkers as measurable indicators of a plant’s cellular response to external stimuli could serve as early warning signals to detect stresses before severe damage occurs. Plant biomarkers have received considerable attention in the last decade as pre-stress indicators for various economically important food crops. This review discusses some biomarkers associated with abiotic and biotic stress conditions and highlights their importance in developing stress-resilient crops. In addition, we highlighted some factors influencing the expression of biomarkers in crop plants under stress. The information presented in this review would educate plant researchers, breeders, and agronomists on the significance of plant biomarkers in stress biology research, which is essential for improving plant growth and yield toward sustainable food production.

“…Although this remains speculative, another possible route/vehicle could be through extracellular vesicles that have received quite a lot of attention in the past decade and have been shown to enable intercellular communication via transport of small proteins, hormones, and sRNA molecules to (neighboring) target cells. While this area of research is booming in animal cell systems, research on this topic in plant systems is still in its infancy [ 12 , 109 ].…”

“…Also depending on the biogenesis of the siRNAs, they can be further divided into different subcategories: trans-acting siRNAs (ta-siRNAs) or secondary phased siRNAs (phasiRNAs), natural antisense transcripts-derived siRNAs (nat-siRNAs), heterochromatic siRNAs (hc-siRNAs), and long siRNAs (lsiRNAs) [ 3 , 4 , 7 , 8 ]. The sRNA categorization and their potential roles in plants have been extensively reviewed elsewhere [ 7 , 9 , 10 , 11 , 12 ]. In this review, we focus on sRNAs potentially involved in virus–plant interactions.…”

Small RNAs (sRNAs) are the hallmark and main effectors of RNA silencing and therefore are involved in major biological processes in plants, such as regulation of gene expression, antiviral defense, and plant genome integrity. The mechanisms of sRNA amplification as well as their mobile nature and rapid generation suggest sRNAs as potential key modulators of intercellular and interspecies communication in plant-pathogen–pest interactions. Plant endogenous sRNAs can act in cis to regulate plant innate immunity against pathogens, or in trans to silence pathogens’ messenger RNAs (mRNAs) and impair virulence. Likewise, pathogen-derived sRNAs can act in cis to regulate expression of their own genes and increase virulence towards a plant host, or in trans to silence plant mRNAs and interfere with host defense. In plant viral diseases, virus infection alters the composition and abundance of sRNAs in plant cells, not only by triggering and interfering with the plant RNA silencing antiviral response, which accumulates virus-derived small interfering RNAs (vsiRNAs), but also by modulating plant endogenous sRNAs. Here, we review the current knowledge on the nature and activity of virus-responsive sRNAs during virus–plant interactions and discuss their role in trans-kingdom modulation of virus vectors for the benefit of virus dissemination.

“…Small RNAs (sRNAs) are a class of non-coding RNAs, with 20 to 35 nucleotides, that are key players in post-transcriptional and transcriptional gene silencing [ 91 ]. MicroRNAs (miRNAs), one of the best studied sRNA classes, are mostly involved in post-transcriptional gene silencing by guiding the cleavage or translation inhibition of complementary target transcripts [ 92 ] with roles in a variety of processes, including plant development, as well as response to abiotic and biotic stresses [ 93 , 94 ].…”

Pine wilt disease (PWD) is a severe environmental problem in Eastern Asia and Western Europe, devastating large forest areas and causing significant economic losses. This disease is caused by the pine wood nematode (PWN), Bursaphelenchus xylophilus, a parasitic migratory nematode that infects the stem of conifer trees. Here we review what is currently known about the molecular defense response in pine trees after infection with PWN, focusing on common responses in different species. By giving particular emphasis to resistance mechanisms reported for selected varieties and families, we identified shared genes and pathways associated with resistance, including the activation of oxidative stress response, cell wall lignification, and biosynthesis of terpenoids and phenylpropanoids. The role of post-transcriptional regulation by small RNAs in pine response to PWN infection is also discussed, as well as the possible implementation of innovative RNA-interference technologies, with a focus on trans-kingdom small RNAs. Finally, the defense response induced by elicitors applied to pine plants before PWN infection to prompt resistance is reviewed. Perspectives about the impact of these findings and future research approaches are discussed.
