Recent studies have expanded the conditions that are directly impacted by translational regulation. This control can balance responses to developmental, environmental, and diverse stress stimuli. Processes with evidence of translational regulation include: immunity to bacterial pathogens, symbiotic interactions, abiotic responses, hormonal perception, light-dependent metabolism, and developmental programs for lateral root initiation, root hair growth, and sepal initiation. Translational control modes rely on the sequence and secondary structure of mRNAs due to the presence of upstream open reading frames (uORFs) and/or internal ribosome entry sites (IRES), protein-binding regions or structures, and the decoding of the epitranscriptomic mRNA modifications such as N<sup>6</sup>-methyladenosine, N<sup>4</sup>-acetylcytidine or pseudouridine. In addition, the post-translational modification of ribosomal proteins and eukaryotic initiation factors such as eIF4G, eIFiso4G, eIF2, as well as changes in ribosome protein composition contribute to translational control. These factors, mRNAs, regulatory proteins and other RNAs can be confined by the formation of biomolecular condensates such as stress granules, processing bodies and others, resulting in paths that modulate translation both globally and specifically. The covered topics place translation as a hub for cell responses during development and within the environmental context. Current understanding of translation has allowed the development of applications in crops, reinforcing the relevance of the study of translational control in plants.</div></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":"88 ","pages":"Article 102799"},"PeriodicalIF":7.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ribosomes require massive nutrient investments, accounting for as much as 50 % of organic phosphorus and 25 % of organic nitrogen in leaves. Optimizing ribosome levels could therefore reduce crop plant fertilizer requirements, an urgent goal for agricultural sustainability. Disruptions to ribosome biogenesis often cause surprising developmental defects, however, and there is substantial confusion and debate among plant geneticists about how to interpret mutant phenotypes caused by defective ribosomes. Here, we propose to adopt the conceptual framework of “ribosomopathies”, human disorders caused by defects in ribosome biogenesis, to better appreciate why some plant developmental processes are more sensitive to ribosome levels than others. We argue that understanding plant ribosomopathies as a broad class of mutants that affect ribosome homeostasis, rather than a series of distinct cases impacting specialized, heterogeneous ribosomes, will encourage productive mechanistic studies of specific ribosome-sensitive developmental processes that could be engineered to circumvent the deleterious effects of restricting ribosome availability.</div></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":"88 ","pages":"Article 102791"},"PeriodicalIF":7.5,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145154983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because plant cytokinesis is brought about by the microtubule-based phragmoplast, the actomyosin system must be required for the centrifugally expanding phragmoplast to recognize the cortical division zone established by the microtubular preprophase band (PPB). It has been intriguing to learn how the two cytoskeletal elements communicate with each other in the two temporally separated cytokinetic apparatuses of the PPB and the phragmoplast. Half a century later, it is now clear that the PPB recruits the actomyosin system to the cortical division zone where the Myosin XI motors form macromolecular assemblies with Kinesin-12 motors and other microtubule-associated proteins. These Cytoskeleton-Associated Motor assemblies at the PPB site (CAMPs) play critical roles in the maintenance of the division site established by the PPB. They receive microtubules emanating from the edge of the expanding phragmoplast so that the developing cell plate can be inserted into the spatially defined position. Therefore, the actomyosin system joins microtubules to orchestrate the recognition of the PPB-defined position by the phragmoplast in order to execute cytokinesis in a spatiotemporally regulated manner in somatic plant cells.</div></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":"88 ","pages":"Article 102790"},"PeriodicalIF":7.5,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145148081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
