Both the tetraploid cultivated potato (&lt;i&gt;Solanum tuberosum&lt;/i&gt; L.) and its wild tuber-bearing relatives belong phylogenetically to the &lt;i&gt;Solanum&lt;/i&gt; section &lt;i&gt;Petota&lt;/i&gt; (Yan et al., &lt;span&gt;2023&lt;/span&gt;). There are more than 100 recognized species of cultivated potatoes and their wild relatives. Like cultivated potatoes, many of these carry the A genome; they are primarily found in South America and are reproductively isolated from Mexican diploid species. The only diploid A-genome species occurring in Mexico is &lt;i&gt;Solanum verrucosum&lt;/i&gt; Schlechtendal, which also serves as a maternal ancestor of Mexican polyploid species (Hosaka et al., &lt;span&gt;2022&lt;/span&gt;). Interestingly, &lt;i&gt;S. verrucosum&lt;/i&gt; is also the only A-genome diploid potato species that is fully self-compatible.&lt;/p&gt;&lt;p&gt;William Behling, first author of the highlighted publication, has long been fascinated by crop wild relatives, and he was especially drawn to &lt;i&gt;S. verrucosum&lt;/i&gt;, which can serve as a bridge between the gene pool of cultivated and wild species because it can be fertilized by a broad range of wild &lt;i&gt;Solanum&lt;/i&gt; species (Behling et al., &lt;span&gt;2024&lt;/span&gt;). The more he worked with &lt;i&gt;S. verrucosum&lt;/i&gt;, the more he wanted to know why this species was able to do something that no other potato species seemed to be able to do—accept pollen from any male-fertile pollen donor.&lt;/p&gt;&lt;p&gt;In &lt;i&gt;S. verrucosum&lt;/i&gt;, self-compatibility has been attributed to the lack of S-ribonuclease (S-RNase) expression in the style (Eijlander et al., &lt;span&gt;2000&lt;/span&gt;). Together with other factors such as HT genes, the S-RNase has a cytotoxic effect on incompatible pollen tubes penetrating the style. However, knocking out the &lt;i&gt;S-RNase&lt;/i&gt; gene in &lt;i&gt;S. tuberosum&lt;/i&gt; is not sufficient to replicate the phenotypes observed in &lt;i&gt;S. verrucosum&lt;/i&gt; (Behling &amp; Douches, &lt;span&gt;2023&lt;/span&gt;). Additionally, there are examples of pollen rejection mechanisms that are independent of S-RNase in interspecific pollinations in tomato (Tovar-Méndez et al., &lt;span&gt;2017&lt;/span&gt;). Therefore, Behling, David Douches and colleagues set out to identify additional genetic factors that determine interspecific compatibility in &lt;i&gt;S. verrucosum&lt;/i&gt; (Behling et al., &lt;span&gt;2025&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;To create a F2 mapping population, segregating for the presence and absence of interspecific reproductive barriers (IRBs), the authors selected two &lt;i&gt;Solanum&lt;/i&gt; parents differing in their reproductive behaviour: DM1S1, a &lt;i&gt;S. tuberosum&lt;/i&gt; doubled monoploid that is effectively male sterile and has functional IRBs, but is able to accept pollen from &lt;i&gt;S. verrucosum&lt;/i&gt;; and MSJJ1813-2, a &lt;i&gt;S. verrucosum&lt;/i&gt; clonal selection that exhibits a high degree of male fertility, self-compatibility and lacks IRBs (Figure 1a).&lt;/p&gt;&lt;p&gt;To test for self-compatibility, the population was then allowed to self-pollinate.

We developed an automated pipeline named LncRAnalyzer featuring retrained models for 60 species. This workflow aims to reduce the likelihood of obtaining protein-coding or partial protein-coding transcripts during lncRNA identification by utilizing eight distinct approaches. We conducted a 10-fold cross-validation of the sorghum models and training sets with their standard ones and other approaches using real-life RNA-Seq datasets and known lncRNA and CDS sequences of sorghum. The results showed that the sorghum models and training sets were outperformed. The pipeline output comprises upset plots illustrating the number of lncRNA/NPCTs identified by the approaches, commonly identified lncRNA and their classes, NPCTs, and expression count tables. A feature-level comparison and benchmarking analysis of LncRAnalyzer with four existing pipelines, namely, LncPipe, LncEvo, lncRNA-Annotation, and Plant-LncPipe, demonstrated that LncRAnalyzer is more comprehensive, easier to implement, and accurate in lncRNA predictions.

In this study, we employed molecular biology and multi-omics techniques to identify an E3 ubiquitin ligase, PtrRZFP4. This E3 ubiquitin ligase exerts a positive regulatory effect on the JA signaling pathway, yet demonstrates differential responses to distinct insect types. We found that upon insect attack, the expression of <i>PtrRZFP4</i> transcripts is upregulated. In addition, PtrRZFP4 is able to interact with PtrJAZ2 and promote the ubiquitination and degradation of PtrJAZ2 protein. Furthermore, <i>PtrRZFP4</i> activates the jasmonic acid (JA) signaling pathway at both the transcriptional and metabolic levels, triggering the synthesis of a large number of secondary metabolites related to insect resistance, such as terpenoids and alkaloids. This ultimately enhances the plant's defense against insect herbivory. The larvae of the specialist insect showed a strong preference for feeding on the leaves of transgenic poplar overexpressing <i>PtrRZFP4</i> (<i>OX-PtrRZFP4</i>), which contain elevated levels of secondary metabolites.

This study has demonstrated that the phytomelatonin receptors SlPMTR1/2 are essential for phytomelatonin protection against cold injury in tomatoes when treated at 4°C for 48 h. Upon sensing 10 μM melatonin, SlPMTR1/2 mitigated oxidative damage through enhancing activities of antioxidant enzyme activities (superoxide dismutase, peroxidase, catalase, ascorbate peroxidase), thereby reducing levels of reactive oxygen species and malondialdehyde accumulation. Meanwhile, SlPMTR1/2 physically interacted with calmodulin SlCaM6, recruiting it to the plasma membrane and reducing its nuclear localization. This sequestration alleviated SlCaM6's inhibition of the transcription factor SlICE1 in the nucleus. Consequently, released SlICE1 activated the expression of <i>SlCBF1</i> and downstream <i>COR</i> genes.

We used weighted gene co-expression network analysis (WGCNA) to analyse cotton transcriptome changes under low-temperature stress. Differentially expressed genes were significantly enriched in those related to ethylene signalling pathways, suggesting their potential role in cold stress responses. The positive effect of ethylene on cold tolerance in cotton was demonstrated by the effects of exogenously applied ethylene precursor 1-aminocyclopropane-1-carboxylic acid and ethylene synthesis inhibitor α-aminoisobutyric acid. Using CRISPR/Cas9, virus-induced gene silencing, as well as overexpression in tobacco, we obtained evidence indicating that the ethylene synthesis gene <i>GhACO1</i> enhanced plant cold tolerance. Transcriptome analysis showed that the C-repeat/DRE binding factor (GhDREB1/CBF) was highly expressed in cotton and significantly upregulated by low-temperature stress. The CUT&amp;Tag approach suggested that GhDREB1 binds to the <i>GhACO1</i> promoter. The direct regulation of <i>GhACO1</i> by GhDREB1 was further confirmed through luciferase reporter gene and yeast one-hybrid detection. These results suggest that <i>GhACO1</i> enhances cold tolerance of cotton via the CBF-dependent pathway. Transgenic cotton plants overexpressing GhDREB1 exhibited elevated GhACO1 expression and improved cold resistance, further supporting the regulatory role of GhDREB1. Our results revealed that <i>GhACO1</i>-mediated ethylene synthesis is modulated by GhDREB1, which positively regulates cold tolerance in cotton. These findings provide valuable insights into the molecular mechanisms underlying cold tolerance in cotton and lay the foundation for improving crop resilience to low-temperature stress.</p>\u0000 </div>","PeriodicalId":233,"journal":{"name":"The Plant Journal","volume":"124 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145278574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
