Genetic analysis indicated that the ligule was controlled by two recessive genes, which were mapped to chromosomes 2AS and 2DL. The mutant allele on chromosome 2AS was named , and it was fine mapped to a 1 Mb physical interval. The mutant allele on chr. 2DL was identified as , a novel allele of with a missense mutation in the second exon, which was used to develop a cleaved amplified polymorphic sequence marker.

Plants with the genotype had 58.41%–82.76% smaller flag leaf angles, 6.4%–24.9% shorter spikes, and a greater spikelet density (0.382 more spikelets per cm) compared with the wild type. Plants with the genotype had 52.62%–82.24% smaller flag leaf angles and no differences in plant height or spikelet density compared with the wild type. plants produced erect leaves with an abnormal lamina joint.

Although previous studies have highlighted the functions of Si application timing and strategies in mitigating Cd-stressed rice, the precise mechanisms underlying the health restoration of Cd-toxic rice and the assurance of grain safety remain elusive. This study explored Cd translocation and detoxification in the shoots of rice regulated by various Si fertilization regimes: Si(T) (all Si added before transplanting), Si(J) (all Si added at jointing), and Si(TJ) (half Si added both before transplanting and at jointing). The findings revealed that the regime of Si(TJ) was more beneficial to rice health and grain safety than Si(T) and Si(J). The osmotic regulators such as proline, soluble sugars, and soluble proteins were significantly boosted by Si(TJ) compared to other Si treatments, and which enhanced membrane integrity, balanced intracellular pH, and increased Cd tolerance of rice. Furthermore, Si(TJ) was more effective than Si(T) and Si(J) on the Cd sequestration in the cell wall, Cd bio-passivation, and the down-regulated expression of the Cd transport genes. The concentrations of Cd in the xylem and phloem treated with Si(TJ) were reduced significantly. Additionally, Si(TJ) facilitated much more Cd bound with the outer layer proteins of grains, and promoted Cd chelation and complexation by phytic acid, phenolics, and flavonoids. Overall, Si (TJ) outperformed Si(T) and Si(J) in harmonizing the phycological processes, inhibiting Cd translocation, and enhancing Cd detoxification in rice plant. Thereby the split Si application strategy offers potential for reducing Cd toxicity in rice grain.","PeriodicalId":501058,"journal":{"name":"The Crop Journal","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141506959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is little research on the function of C-14 sterol reductase in rice. Compared with the wild type, an mutant showed dwarf phenotype and premature aging in the second leaf during the trefoil stage, and abnormal development of leaf veins during the tillering stage. The mutant showed signs of aberrant PCD, as evidenced by TUNEL staining. This suggested that high ROS buildup caused DNA damage and ROS-mediated cell death in the mutant. The mutant also showed decreased chlorophyll content and aberrant chloroplast structure. Sequencing of the mutant allele revealed a non-synonymous G to A mutation in the final intron, leading to early termination. Here, we identified the allele, cloned it by Mutmap sequencing, and verified it by complementation. HPLC-MS/MS assays demonstrated that the mutation caused lower phytosterol levels.
