An extremely narrow or wide tiller angle adversely affects rice yield. Thus, a suitable tiller angle is considered a major factor to achieve ideal plant architecture in rice. In this study, we identified a major quantitative trait locus (QTL) that controls tiller angle and cloned the gene, TILLER ANGLE CONTROL 5 (TAC5), which encodes a NAC domain-containing transcription factor. Epigenetic variants at the CG site in the TAC5 promoter were stably inherited and associated with TAC5 mRNA expression. The TAC5 epiallele with a hypermethylated cytosine in the promoter exhibited an immediate response to gravistimulation with a simultaneous elevation of H₂O₂ levels at the early stage of gravistimulation. Furthermore, TAC5 affected the expression patterns of transcripts involved in reactive oxygen species (ROS) generation and the response to excessive ROS. Population genetics and evolutionary analyses revealed that TAC5 alleles for the narrow tiller angle originated from a wild progenitor and were selected independently in temperate japonica and indica subspecies during domestication. Our results provide insight into the genetic mechanism of tiller angle control in rice and suggest potential applications of TAC5 in developing rice varieties with an ideal plant architecture.</p>","PeriodicalId":21408,"journal":{"name":"Rice","volume":"18 1","pages":"44"},"PeriodicalIF":4.8,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144161830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the risk of flooding during germination and at the early seedling and vegetative stages is high. Therefore, the capacity for anaerobic germination in waterlogged soils, as well as tolerance to partial and complete submergence, are both essential. It remains unclear whether anaerobic germination and flood tolerance are linked or if they act independently in the environment. Therefore, it is timely to investigate the relationship between these two traits in the context of progressing climate change. We investigated the submergence tolerance of 4-week-old plants of three African landraces, which had previously been shown to possess anaerobic germination capacity. Additionally, we included one submergence-sensitive check and two tolerant checks. These six genotypes were evaluated at three time points: initially (prior to submergence), after three days of submergence, and at the time of desubmergence following 29 days of submergence. We measured survival, key photosynthetic traits (leaf gas films, underwater net photosynthesis, chlorophyll concentration), and carbohydrate reserves. We found that the African landraces tolerant to anaerobic germination all outlived the submergence-sensitive check, 'IR42,' during 29 days of complete submergence. Moreover, all tested genotypes exhibited significant declines over the 29 days of submergence in gas film thickness, underwater net photosynthesis, leaf chlorophyll concentration, and leaf water-soluble carbohydrates and starch. However, no significant differences were observed among the genotypes. The underlying mechanisms of anaerobic germination tolerance in the three African landraces remain unknown, as they do not possess the gene Anaerobic Germination 1 (AG1). Furthermore, it is unclear whether the three genotypes contain the gene Submergence 1 (SUB1); however, SUB1 confers submergence tolerance only and does not provide tolerance to anaerobic germination. Based on the present study, we cannot rule out the possibility that the novel anaerobic germination tolerance observed in the three African landraces is somehow linked to submergence tolerance as well. A thorough bioinformatic analysis is therefore needed to further characterize these landraces.</p>","PeriodicalId":21408,"journal":{"name":"Rice","volume":"18 1","pages":"45"},"PeriodicalIF":4.8,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144161838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These challenges may be addressed by adopting climate-resilient practices and using advanced agronomic techniques. These challenges are being addressed through innovative applications of plant biotechnology and microbiology, which offer targeted solutions to enhance sorghum's resilience. For instance, biotechnological tools like CRISPR/Cas9 enable precise genetic modifications to improve drought and heat tolerance, while microbial inoculants, such as plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF), enhance nutrient uptake and stress tolerance through symbiotic interactions. However, biotechnological tools lead to the development of sorghum varieties with heat, drought and salinity tolerance, while marker-assisted selection significantly accelerates breeding for stress-resilient traits. When genetic engineering is introduced, genes encoding heat shock proteins, Osmo protectants and antioxidant pathways are introduced to increase plant resistance to abiotic stress. These compounds stabilise cellular structures, protect enzymes, and maintain osmotic balance, enhancing the plant's ability to survive and function in adverse environmental conditions. At the same time, it is reported that microbiology offers beneficial microbes, nitrogen-fixing bacteria, phosphate-solubilizing microorganisms, and arbuscular mycorrhizal fungi that help enhance nutrient availability, soil health and water uptake. Combinations of endophytes and microbial inoculants enhance plant immunity to pests and diseases while increasing tolerance to stress. Biocontrol agents such as Bacillus and Trichoderma contain suppression of pathogens and need less dependence on the use of chemical pesticides. On top of that, genetic modification increases the nutritional quality of sorghum biofortified. This is where biotechnology and microbiology work together to deliver sustainable farming systems reducing environmental impacts, boosting yields and securing food supply under environmental stresses. This review aims to examine the synergistic integration of plant biotechnology and microbial interactions as a strategy to enhance sorghum's resilience to climate-induced stresses, including drought, elevated temperatures, and nutrient-deficient soils. It highlights recent advancements in biotechnological tools such as gene editing, marker-assisted selection, and tissue culture, alongside the emerging role of plant-beneficial microbes in promoting stress tolerance and improving soil health.
