Plant–pathogen interactions induce a signal transmission series that stimulates the plant’s host defense system against pathogens and this, in turn, leads to disease resistance responses. Plant innate immunity mainly includes two lines of system, called pathogen-associated molecular pattern-triggered (PTI) effector-triggered (ETI). There is extensive exchange recognition process triggering plant immune signaling network. messenger molecules, such as calcium ions, reactive oxygen species, nitric oxide, hormone salicylic acid, jasmonic ethylene, play key roles inducing In addition, heterotrimeric G proteins, mitogen-activated protein kinase cascade, non-coding RNAs (ncRNAs) important regulating transduction This paper summarizes status progress pathway research recent years; discusses complexities of, among, pathways; forecasts future prospects provide new ideas for prevention control diseases.

Crops are exposed to attacks by various pathogens that cause substantial yield losses and severely threaten food security. To cope with pathogenic infection, crops have elaborated strategies enhance resistance against pathogens. In addition the role of protein-coding genes as key regulators in plant immunity, accumulating evidence has demonstrated importance non-coding RNAs (ncRNAs) immune response. Here, we summarize roles molecular mechanisms endogenous ncRNAs, especially microRNAs (miRNAs), long ncRNAs (lncRNAs), circular (circRNAs), immunity. We discuss coordination between miRNAs small interfering (siRNAs), lncRNAs or siRNAs, circRNAs regulation responses. also address cross-kingdom mobile plant–pathogen interactions. These insights improve our understanding which regulate immunity can promote development better approaches for breeding disease-resistant crops.

Long noncoding RNA lncRNA354 functions as a competing endogenous RNA of miR160b to regulate ARF genes in response to salt stress in upland cotton

Plant Cell & Environment, Год журнала: 2021, Номер 44(10), С. 3302 - 3321

Long non-coding RNAs (lncRNAs) play important roles in response to biotic and abiotic stress through acting as competing endogenous (ceRNAs) decoy mature miRNAs. However, whether this mechanism is involved cotton salt remains unknown. We report the characterization of an lncRNA, lncRNA354, whose expression was reduced salt-treated localized at nucleus cytoplasm. Using target mimic (eTM) analysis, we predicted that lncRNA354 had a potential binding site for miR160b. Transient tobacco demonstrated miR160b eTM attenuated suppression its genes, including auxin factors (ARFs). Silencing or overexpressing affected ARFs. targets GhARF17/18 resulted taller plants enhanced resistant stress. Overexpression Arabidopsis led dwarf plants, decreased root dry weight tolerance. Our results show lncRNA354-miR160b effect on may modulate signalling thus affect growth. These also shed new light lncRNA-associated responses

Plants employ sophisticated mechanisms to control developmental processes and cope with environmental changes at transcriptional post-transcriptional levels. MicroRNAs (miRNAs) long noncoding RNAs (lncRNAs), two classes of endogenous RNAs, are key regulators gene expression in plants. Recent studies have identified the interplay between miRNAs lncRNAs as a novel regulatory layer On one hand, target for production phased small interfering (phasiRNAs). other serve origin or regulate accumulation activity transcription Theses lncRNA-miRNA interplays crucial plant development, physiology responses biotic abiotic stresses. In this review, we summarize recent advances biological roles, interaction computational predication methods

Plants are continuously exposed to various biotic and abiotic stresses in the natural environment. To cope with these stresses, they have evolved a multitude of defenses mechanisms. With rapid development genome sequencing technologies, large number non-coding RNA (ncRNAs) been identified tomato, like microRNAs (miRNAs) long RNAs (lncRNAs). Recently, more evidence indicates that many ncRNAs involved plant response tomato. In this review, we summarize recent updates on regulatory roles tomato abiotic/biotic responses, including (high temperature, drought, cold, salinization, etc.) (bacteria, fungi, viruses, insects, stresses. Understanding molecular mechanisms mediated by will help us clarify future directions for ncRNA research resistance breeding

Robust plant immune systems are fine-tuned by both protein-coding genes and non-coding RNAs. Long RNAs (lncRNAs) refer to with a length of more than 200 nt usually do not have function belong any other well-known RNA types. The non-protein-coding, low expression, non-conservative characteristics lncRNAs restrict their recognition. Although studies in plants the early stage, emerging shown that employ regulate immunity. Moreover, response stresses, numerous differentially expressed, which manifests actions low-expressed makes plant–microbe/insect interactions convenient system study functions lncRNAs. Here, we summarize current advances lncRNAs, discuss regulatory effects different stages immunity, highlight roles diverse interactions. These insights will only strengthen our understanding but also provide novel insight into responses basis for further research this field.

Combination of PAMP‐induced peptide signaling and its regulator SpWRKY65 boosts tomato resistance to Phytophthora infestans

The Plant Journal, Год журнала: 2025, Номер 121(6)

Опубликована: Март 1, 2025

SUMMARY Late blight, caused by Phytophthora infestans ( P. ), seriously compromises tomato growth and yield. PAMP‐induced peptides (PIPs) are secreted that act as endogenous elicitors, triggering plant immune responses. Our previous research indicated the exogenous application of PIP1 from Solanum pimpinelifolium L3708, named SpPIP1, enhances resistance to . However, little is known about roles additional family members in In addition, there remains a significant gap understanding receptors SpPIPs transcription factors (TFs) regulate signaling defense, combination TFs defending against pathogens rarely studied. This study demonstrates SpPIP‐LIKE1 (SpPIPL1) also strengthens affecting phenylpropanoid biosynthesis pathway. Both SpPIP1 SpPIPL1 trigger defense responses manner dependent on RLK7L. Tomato plants overexpressing precursors (SpprePIP1 SpprePIPL1) exhibited enhanced expression pathogenesis‐related genes, elevated H 2 O ABA levels, increased lignin accumulation. Notably, SpWRKY65 was identified transcriptional activator SpprePIP1 SpprePIPL1 Disease assays gene analyses revealed overexpression (OEWRKY65) confers , while wrky65 knockout led opposite effect. Intriguingly, transgenic studies showed either spraying OEWRKY65 with or co‐overexpressing further augmented resistance, underscoring potential stacking enhancing disease resistance. summary, this offers new perspectives controlling late blight developing varieties improved The results emphasize an eco‐friendly strategy for crop protection, laying theoretical foundation advancing breeding.
