Rice is highly susceptible to prolonged flooding, with a drastic decline in yields if inundation persists for more than 7 d, especially during the reproductive stage. Although the <em>SUB1</em> QTL, which confers tolerance to complete submergence during the vegetative stage, has been incorporated into breeding programs, the development of alternative sources is crucial. These alternatives would broaden the genetic base, mitigate the influence of the genomic background, and extend the efficacy of <em>SUB1</em> QTL to withstand longer submergence periods (up to approximately 21 d). Contemporary breeding strategies predominantly target submergence stress at the vegetative stage. However, stagnant flooding (partial submergence of vegetative parts) during the reproductive phase inflicts severe damage on the rice crop, leading to reduced yields, heightened susceptibility to pests and diseases, lodging, and inferior grain quality. The ability to tolerate stagnant flooding can be ascribed to several adaptive traits: accelerated aerenchyma formation, efficient underwater photosynthesis, reduced radial oxygen loss in submerged tissues, reinforced culms, enhanced reactive oxygen species scavenging within cells, dehydration tolerance post-flooding, and resistance to pests and diseases. A thorough investigation of the genetics underlying these traits, coupled with the integration of key alleles into elite genetic backgrounds, can significantly enhance food and income security in flood-prone rice-growing regions, particularly in coastal high-rainfall areas and low-lying river basins. This review aims to delineate an innovative breeding strategy that employs genomic, phenomic, and traditional breeding methodologies to develop rice varieties resilient to various dimensions of flooding stress at both the vegetative and reproductive stages.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"32 2","pages":"Pages 160-176"},"PeriodicalIF":5.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143820803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a lack of literature reviewing the measures and mechanisms to regulate the regeneration rate, as well as the challenges in the production of ratoon rice. This study explores the effects of different varieties, climatic conditions (light and temperature), and cultivation measures (fertilizer management, cropping system, harvest method, water management, and plant growth regulators) on the regeneration rate and grain yield of the ratoon season. It summarizes and analyzes the possible mechanisms that affect the germination of regenerated buds from the perspectives of material accumulation and transportation, hormone metabolism, and molecular mechanisms, and identifies main factors currently limiting the development of ratoon rice. A significant positive correlation between the regeneration rate and grain yield of the ratoon season was found, regulated by varieties, temperatures, light resources, and cultivation measures. Improving the regeneration rate can effectively increase the production of ratoon rice. Notably, rice varieties with high regeneration ability exhibit characteristics such as a suitable growth period, a developed root system, high single-stem weight, a relatively small ratio of grain number to green leaf area, and strong lodging resistance in the main season. Additionally, the germination of regenerated buds is regulated by the accumulation and transport of endogenous hormones (indole-3-acetic acid, gibberellins, and cytokinins), photoassimilates (non-structural carbohydrates), and reactive oxygen metabolism. To further demonstrate the grain yield potential of the ratoon season, improvements are needed in three key areas: the cultivation system of low-stubble ratoon rice, the development of specialized harvesters, and the breeding of rice varieties with high-temperature tolerance during the main crop and low-temperature tolerance during the ratoon crop.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"32 2","pages":"Pages 177-192"},"PeriodicalIF":5.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143820804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we identified proteins interacting with OsCERK1 and uncovered a novel heavy metal-associated domain-containing protein, OsHPP08. Our findings demonstrate that OsCERK1 phosphorylated and stabilized OsHPP08. Through structural analysis using AlphaFold, a yeast sensitivity assay of the Cu uptake-deficient yeast mutant, and Cu level measurements in <em>oshpp08</em> mutants and overexpression plants (<em>OsHPP08OE</em>), we revealed that OsHPP08 facilitated Cu uptake. Additionally, rice seedling infection assays demonstrated that OsHPP08 positively contributed to blast resistance, with both OsCERK1 and OsHPP08 being essential for Cu-modulated blast resistance. Further analyses suggested that OsCERK1 and OsHPP08 likely enhanced blast resistance by regulating the antioxidant system and increasing H₂O₂ accumulation. In conclusion, OsCERK1 promoted Cu uptake by stabilizing OsHPP08, and together they contributed to Cu-modulated blast resistance, likely through the modulation of reactive oxygen species accumulation.

Analysis of the methanolic extract of the cyanobacterial- bacterial biofilm (CBB) showed the activity of antioxidants, such as 2-methoxy phenol and pentadecane, which are proven to improve plant-microbe interactions and plant growth, respectively. Treatment of rice seeds with CBB extract at 100 mL/kg or 200 mL/kg showed significant enhancement in germination rate and seedling length. Therefore, a pot culture experiment with the CBB formulations was carried out, and different growth and yield parameters were recorded. Principal component analysis showed that plant growth, yield, soil dehydrogenase activity, and soil chlorophyll content were positively correlated with rice plants amended with vermiculite-based CBB at 2 kg/hm² followed by a spray with aqueous CBB formulation at 5 mL/L at 15 and 30 d after rice transplanting grown with a 25% reduced level of nitrogen/phosphorus/potassium chemical fertilizers than the recommended dose. Further, Pearson correlation analysis showed that yield was positively correlated with soil dehydrogenase (<em>r</em> = 0.92**) and soil chlorophyll content (<em>r</em> = 0.96**).

In this study, we conducted a metabolomic analysis on both blast-resistant (Digu) and -susceptible (Lijiangxintuanheigu) rice varieties to uncover novel metabolites that enhance blast resistance. We found that 24 and 48 h post-inoculation with <em>Magnaporthe oryzae</em> were critical time points for metabolomic profiling, based on the infected status of <em>M. oryzae</em> in rice and the observed differences in shikimate accumulation between the two varieties. Following metabolomic analysis, we identified nine flavonoids that were differentially accumulated and are considered potential candidates for disease control. Among these, apigenin-7-glucoside, rhamnetin, and spireoside were found to be effective in controlling blast disease, with spireoside demonstrating the most pronounced efficacy. We discovered that spireoside controlled blast disease by inhibiting both spore germination and appressorium formation in <em>M. oryzae</em>, primarily through disrupting cell membrane integrity. However, spireoside did not induce rice immunity. Furthermore, spireoside was also effective in controlling sheath blight disease.
