In rice, these kinases actively participate in immune responses against a variety of pathogens, including fungi, bacteria, and viruses. However, research on the specific response mechanisms and the spectrum of different kinase activities against various pathogens remains insufficient. This review provides an in-depth and comprehensive overview of the types and functions of RLKs and RLCKs involved in disease resistance, emphasizing the central role of certain RLKs and RLCKs in the plant immune system. These kinases can recognize specific molecular patterns of pathogens and rapidly initiate an immune response in rice. Furthermore, the activity and functional regulation of these key kinases are tightly controlled by various post-translational modifications, such as phosphorylation and ubiquitination. This meticulous regulation ensures that the rice immune system’s response is both precise and timely, effectively balancing the intensity of the immune response and preventing potential issues caused by either hyperactivity or insufficiency. By synthesizing current research findings, this review not only broadens our understanding of the role of RLKs and RLCKs in plant immunity but also provides new perspectives and strategies for future research on disease resistance breeding in rice. Future studies are expected to delve deeper into the signaling networks and regulatory mechanisms of these kinases, exploring their potential in agricultural production to develop rice varieties with enhanced disease resistance.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"31 6","pages":"Pages 643-658"},"PeriodicalIF":5.6,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143178331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aerobic irrigation methods have proven to be efficacious in mitigating CH₄ emissions in paddy cultivation. The promising role of compound microbial agents in refining the rhizospheric ecosystem suggests their potential as novel agents in reducing CH₄ emissions from paddy fields. To explore a new method of using compound microbial agents to reduce CH₄ emissions, we conducted pot and field experiments over the period of 2022‒2023. We measured CH₄ flux, the redox potential (Eh) of the soil, the concentration of dissolved oxygen (DO) in the floodwater, and the gene abundance of both methanogens (<em>mcrA</em>) and methanotrophs (<em>pmoA</em>). The results showed that the application of the compound microbial agent led to a significant increase in the DO levels within the floodwater and an increase of 9.26% to 35.01% in the Eh of the tillage soil. Furthermore, the abundance of <em>pmoA</em> increased by 31.20%, while the <em>mcrA/pmoA</em> ratio decreased by 25.96% at the maximum tillering stage. Applying 45−75 kg/hm² of the compound microbial agent before transplanting resulted in a reduction of cumulative CH₄ emissions from paddy fields by 17.49% in single- cropped rice and 43.54% to 50.27% in double-cropped late rice during the tillering stage. Correlation analysis indicated that CH₄ flux was significantly negatively correlated with <em>pmoA</em> gene abundance and soil Eh, and positively related to the <em>mcrA</em>/<em>pmoA</em> ratio. Additionally, soil Eh was significantly positively correlated with <em>pmoA</em> gene abundance, suggesting that paddy soil Eh indirectly affected CH₄ flux by influencing the <em>pmoA</em> gene abundance. In conclusion, the pre-planting application of the compound microbial agent at a rate of 45‒75 kg/hm² can enhance the Eh in the rhizosphere and increase the abundance of the <em>pmoA</em> gene, thereby reducing CH₄ emissions from paddy fields during the tillering stage of rice growth.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"31 6","pages":"Pages 740-750"},"PeriodicalIF":5.6,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141707327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that the increased respiratory carbon loss under high night temperatures (HNT) could be compensated for by increased photosynthesis during the day following HNT exposure. Two rice genotypes, Vandana (HNT-sensitive) and Nagina 22 (HNT-tolerant), were exposed to HNT (4 °C above the control) from flowering to physiological maturity. They were assessed for alterations in the carbon balance of the source (flag leaf) and its subsequent impact on grain filling dynamics and the quality of spatially differentiated sinks (superior and inferior spikelets). Both genotypes exhibited significantly higher night respiration rates. However, only Nagina 22 compensated for the high respiration rates with an increased photosynthetic rate, resulting in a steady production of total dry matter under HNT. Nagina 22 also recorded a higher grain-filling rate, particularly at 5 and 10 d after flowering, with 1.5- and 4.0-fold increases in the translocation of ¹⁴C sugars to the superior and inferior spikelets, respectively. The ratio of photosynthetic rate to respiratory rate on a leaf area basis was negatively correlated with spikelet sterility, resulting in a higher filled spikelet number and grain weight per plant, particularly for inferior grains in Nagina 22. Grain quality parameters such as head rice recovery, high-density grains, and gelatinization temperature were maintained in Nagina 22. An increase in the rheological properties of rice flour starch in Nagina 22 under HNT indicated the stability of starch and its ability to reorganize during the cooling process of product formation. Thus, our study showed that sink adjustments between superior and inferior spikelets favored the growth of inferior spikelets, which helped to offset the reduction in grain weight under HNT in the tolerant genotype Nagina 22.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"31 5","pages":"Pages 572-586"},"PeriodicalIF":5.6,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on F_5:6 generation plants derived from inter-subspecific crosses (Nipponbare × KDML105) with low (LS) and high seed-setting rates (HS), in which normal pollen fertility was observed. However, LS plants showed a reduced number of pollen grains adhering to the stigma and fewer pollen tubes reaching the ovules at 4‒5 h post-pollination, compared with HS plants. Bulked segregant RNA-Seq analysis of pollinated pistils from the HS and LS groups revealed 249 and 473 differentially expressed genes (DEGs), respectively. Kyoto Encyclopedia of Genes and Genomes analysis of the HS and LS- specific DEGs indicated enrichment in metabolic pathways, pentose and glucuronate interconversions, and flavonoid biosynthesis. Several of these DEGs exhibited co-expression with pollen development genes and formed extensive clusters of co-expression networks. Compared with LS pistils, enzyme genes controlling pectin degradation, such as <em>OsPME35</em> and <em>OsPLL9</em>, showed similar expression patterns, with higher levels in HS pistils pre-pollination. <em>Os02g0467600</em>, similar to cinnamate 4-hydroxylase gene (<em>CYP73</em>), involved in flavonoid biosynthesis, displayed higher expression in HS pistils post-pollination.
