Understanding the mechanisms of plant-pathogen interactions is essential for developing genetic strategies to safeguard crops against disease. <em>Ralstonia solanacearum</em>, a soil-borne pathogen of significant importance, has emerged as a prominent model for studying plant-pathogenic bacteria due to its extensive genetic diversity, prolonged environmental persistence, unusually broad host range, and notably, its considerable impact on agriculture. To successfully invade and propagate in plants, <em>R</em>. <em>solanacearum</em> employs diverse extracellular pathogenic factors and intracellular type III effectors (T3Es) to evade or disrupt plant immunity. In response, plants have evolved a two-layered innate immune system, represented by pattern-triggered immunity (PTI)—mediated by cell-surface pattern recognition receptors (PRRs) and effector-triggered immunity (ETI)—mediated by intracellular nucleotide-binding and leucine-rich repeat receptors (NLRs). Over the past three decades, many factors contributing to the dynamic interactions between <em>R</em>. <em>solanacearum</em> and plants have been identified. This comprehensive overview aims to summarize the current understanding of <em>R. solanacearum</em> extracellular virulence factors and intracellular T3Es, as well as host plant PRRs recognizing characterized PAMPs (pathogen-associated molecular patterns), and plant NLR-mediated recognition of avirulent T3Es that govern plant host-<em>R. solanacearum</em> interactions. Additionally, we highlight current endeavors aimed at applying this knowledge to developing enhanced plant disease resistance tools, address prevailing challenges, and provide insights into future research perspectives.</p></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"1 ","pages":"Article 100014"},"PeriodicalIF":0.0,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949952624000049/pdfft?md5=70ba1ee28a25b97c9cf9e70bc9f4632d&pid=1-s2.0-S2949952624000049-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139890489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The symbiosome represents a temporary organelle in which rhizobia-encoded nitrogenase catalyzes dinitrogen conversion to ammonia in an oxygen-regulated microenvironment. Investigating symbiosome biology will undoubtedly improve our understanding of nitrogen fixation mechanisms and highlight novel targets for improving nitrogen fixation efficiency. Recent research advancements have taken place on regulatory aspects of symbiosome generation and functions, but obtaining spatiotemporally resolved symbiosome proteome and metabolomes, as well as tracking and deciphering its intracellular communication, is challenging. As a symbiotic interface, the symbiosome membrane proteome is largely composed of plant-derived proteins, while the symbiosome space between the symbiosome membrane and bacteria consists of proteins and metabolites from the rhizobium and plant. In the unique microenvironment, symbiosome proteins likely perform multiple tasks via their moonlighting functions, accounting for the many unsolved questions associated with symbiotic nitrogen fixation. In this review, we outline the current knowledge regarding the composition and potential moonlighting functions of symbiosome proteins. We highlight our current understanding of emergent symbiosome properties closely tied to nitrogen fixation activity. Ultimately, we discuss the challenges and opportunities for discovering new paradigms in symbiosome biology using recently developed technologies.</p></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"1 ","pages":"Article 100015"},"PeriodicalIF":0.0,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949952624000050/pdfft?md5=a165278179ea71d9734a2e7246eedc71&pid=1-s2.0-S2949952624000050-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139885997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unleashing the potential of the plant microbiome stands as a pivotal approach to safeguard and rejuvenate our planet. However, the complex nature of microbiome interactions, coupled with their limited persistence in intricate environmental settings due to gaps in understanding or technological limitations, has impeded substantial progress in this field. This review explores innovative and revitalized strategies for harnessing microbiome-based enhancements in crop fitness. Additionally, we illuminate the challenges encountered in deciphering the intricate interplay between the microbiome and its host, particularly in the context of mitigating the adverse influences of climate change on crop resilience. To navigate these complexities, we advocate for a comprehensive approach that considers both host and microbiome-oriented perspectives.

Closing stomata, limiting water dissipation, and improving water use efficiency are important components of plant drought responses. In our study, the MYB-like transcription factor ZmMYB56, expressed in maize guard cells, played important roles in regulating stomatal closure and drought tolerance. Mutations in ZmMYB56 triggered elevated stomatal conductance, rapid water loss in isolated leaves, and severe drought sensitivity in plants. ZmMYB56 possesses transcriptional activation activity, and is expressed specifically in stomatal guard cells. As an R2R3 transcription factor, ZmMYB56 can bind the cis-acting element on the <em>ZmTOM7</em> promoter sequence, activating its expression. Correspondingly, the <em>ZmTOM7</em> transcript level is downregulated in <em>Zmmyb56</em> seedlings. Transgenic <em>Arabidopsis</em> plants overexpressing <em>ZmTOM7</em> exhibit limited stomatal conductance and elevated drought tolerance, while the <em>ZmTOM7</em> mutation is linked to higher stomatal conductance and substantial drought sensitivity in maize seedlings. According to these findings, we conclude that <em>ZmTOM7</em> operates as a key target gene of ZmMYB56 and is involved in ZmMYB56-regulated stomatal closure and maize drought tolerance.

Arbuscular mycorrhizal (AM) fungi release diffusible signaling molecules known as mycorrhizal factors (Myc factors) to establish communication with plants. Extensive research has established that Myc factors play a pivotal role in orchestrating root architectural changes before fungal colonization occurs. In this study, we investigate the impact of the Myc factor CO4 on the architectural modifications of rice roots. Our findings reveal that CO4 actively promotes the development of crown roots and lateral roots in wild-type rice plants. Furthermore, we have identified that pivotal role of receptors such as OsCERK1, OsMYR1, and OsCEBiP in mediating the stimulatory effects of CO4. Knockout mutants of these receptors exhibit a significant reduction in the number of lateral roots and crown roots with lateral roots, along with decreased sensitivity to CO4. Conversely, the overexpression of OsMYR1 leads to a substantial increase in lateral roots and crown roots with lateral roots, even in the absence of CO4 treatment. We propose that CO4-induced root architecture development offers promising opportunities for enhancing lateral root growth, which, in turn, can promote nutrient uptake through direct Myc factor application.</p></div>","PeriodicalId":100953,"journal":{"name":"New Crops","volume":"1 ","pages":"Article 100009"},"PeriodicalIF":0.0,"publicationDate":"2023-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949952623000080/pdfft?md5=df11a97d6a630a0b25ca903928345754&pid=1-s2.0-S2949952623000080-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139022066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
