Recent studies suggest that plants, such as pea (<em>Pisum sativum</em>) can recruit beneficial bacteria in the rhizosphere potentially influencing their resilience to insect pests. However, the implications of this microbial recruitment in plant-insect interactions remain underexplored. In this study, we investigated how key rhizosphere bacteria of pea, including <em>Rhizobium leguminosarum, S. sediminicola</em>, and <em>S. daechungensis</em>, modulate pea-aphid (<em>Acyrthosiphon pisum</em>) interactions and affect plant productivity. We assessed both the bottom-up effects of individual and combined bacterial inoculations on plant health and aphid performance, and the top-down effects of aphid infestation on soil functionality. Our results demonstrate that inoculation with <em>S. sediminicola</em> and/or <em>S. daechungensis</em> significantly reduced aphid fecundity, while mitigating aphid-induced stress on pea plants, thereby supporting overall plant growth and productivity. Conversely, aphid infestation negatively impacted soil functionality, potentially disrupting beneficial microbial communities. These findings highlight the potential of targeted microbial recruitment as a sustainable approach to enhance plant productivity and resilience against aphid pests.</div></div>","PeriodicalId":34736,"journal":{"name":"Plant Stress","volume":"15 ","pages":"Article 100703"},"PeriodicalIF":6.8,"publicationDate":"2024-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098267","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}

AP2/ERF transcription factors regulate genes that help plants survive and adapt to harsh environmental stresses. Although ERF109 is linked to drought tolerance, its exact role remains unknown. To investigate this, we generated mutant alleles of the <em>OsERF109</em> gene in an indica rice cultivar and studied their response to simulated drought conditions. Our findings show that the <em>Oserf109</em> mutation exhibits no visible effect on plant growth and development under optimum environmental conditions. However, the <em>Oserf109</em> null mutant demonstrated improved drought tolerance and survival rates. This improvement is due to reduced transpiration, lower canopy temperature, and better plant water status. The <em>Oserf109</em> mutant maintains cellular hydration and membrane stability by increasing proline content under drought stress. The <em>Oserf109</em> mutant also exhibits enhanced water use efficiency and improved gaseous exchange, which boosts photosynthetic efficiency, strengthens antioxidant defenses, and preserves chloroplast integrity, protecting the plant from oxidative damage during drought. Additionally, <em>Oserf109</em> knockout plants showed increased tolerance to osmotic stress and reduced sensitivity to ABA, resulting in better seedling growth and higher germination rates. Our research reveals that the <em>Oserf109</em> mutation enhances rice crop resilience and yield under adverse conditions. These findings illustrated the inhibitory regulatory role of <em>OsERF109</em> in the drought tolerance mechanism, with the mutant form of this allele demonstrating potential implications in developing resilient rice cultivars for drought stress.</div></div>","PeriodicalId":34736,"journal":{"name":"Plant Stress","volume":"15 ","pages":"Article 100701"},"PeriodicalIF":6.8,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098948","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}

In nature, plants encounter a wide range of stressors, including both biotic and abiotic factors, which can negatively impact their growth, development, and overall fitness. Plants therefore need to develop coping mechanisms to these stressors. Key players in these regulatory processes include transcription factors, kinases, and various signalling molecules. MicroRNAs (miRNAs) are a class of small, non-coding RNA molecules that play a pivotal role in plant stress tolerance. MiRNAs are increasingly recognized as key players in orchestrating how plants and other organisms adapt to a multitude of environmental stresses. However, little is still known on the function of miRNAs in plant responses to multiple stresses. This systematic review aimed to provide a comprehensive overview and analysis of the current state of knowledge regarding the role of microRNAs (miRNAs) in plant responses to multiple stresses under the changing environmental. The review paper has synthesized the existing research, highlighted key findings, and offered insights into the significance of miRNAs in enhancing plant resilience to various environmental stressors.

Transcriptomic changes in the host support increased susceptibility to the pathogen while the <em>in planta</em> fungal transcriptome suggests prioritization of survival in the drought-stressed host. Upon rewatering, changes in the host transcriptome suggest allocation of resources to stress responses at the expense of growth and carbohydrate storage while that of the pathogen indicate downregulation of some fungal metabolic pathways potentially because the pathogen takes advantage of changes in the host.

This study aims to investigate whether exogenous application of proline and its encapsulated form can effectively reduce the adverse effects of high temperatures compared to optimal conditions. The treatments involved two temperature conditions: 25 ± 2 °C (CT) and 40 ± 2 °C (HT), along with various proline sources, including distilled water (C), proline (Pr), and encapsulated proline (N-Pr), each at a concentration of 20 mM. The findings of this study revealed that high-temperature stress led to a decrease in PIP1 gene expression which plays a crucial role in regulating water transport and maintaining cellular hydration, and linoleic acid content in pepper plants. The application of proline resulted in improved growth traits under optimal temperature in comparison with control and N-Pr. Furthermore, electrolyte leakage (EL) decreased by 45 % with the application of Pr under high temperature compared to control. Under heat stress, the application of N-Pr enhanced the chlorophyll index, phenol, and proline concentration by 24 %, 102 %, and 147 % respectively.
