This study evaluated a diverse collection of 31 rice cultivars for resistance and the role of cytochrome P450 genes in resistance or susceptibility. The phenotype of the resistant was characterized by the ability of the variety to support no or few emerging Striga. The presence or absence of the cytochrome P450 gene was determined by Multiplex PCR analysis. Upon examination, it became clear that five cultivars showed good resistance to , while twenty exhibited intermediate resistance and six were very susceptible. In contrast, the resistant genotypes had few or no emerged . emerged early and rapidly in susceptible genotypes, supporting a higher number of emerged and attached and dry weight per plant. Multiplexed PCR analysis showed that 87.1% of the cultivars possessed the 93-11/Bala alleles, and 12.9% had the Nipponbare/Azucena alleles for strigolactone biosynthesis. Evaluating the variability of the 3 000 rice genomic data in these genes revealed similar results. The outcome of this research identified genotypes that are resistant, tolerant, and susceptible. This finding may be useful in breeding program for resistance. The next steps for this research could involve testing the resistant genotypes in the field or using them as a starting point for a genetic experiment.","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"50 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140154211","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}

Notably, the number of prominent rice individuals also increased, and their plasticity was enhanced following AMF inoculation. AMF led to an increase in the net photosynthetic rate and antioxidant enzyme activity of rice. In the AMF treatment group, the Cd concentration in the rice roots was significantly higher (19.1%‒68.0%) compared with that in the control group. Conversely, the Cd concentration in the rice seeds was lower in the AMF treatment group, indicating that AMF facilitated the sequestration of Cd in rice roots and reduced Cd accumulation in the seeds. Path coefficients varied across different treatments, suggesting that AMF inoculation reduced the direct impact of soil Cd concentration on the total Cd accumulation in seeds.

Flooded soils play a significant role in methane production, where the anaerobic conditions promote the production of methane by methanogenic microorganisms. Rice fields contribute a considerable portion of agricultural methane emissions, as rice plants provide both factors that enhance and limit methane production. Rice plants harbor both methane- producing and methane-oxidizing microorganisms. Exudates from rice roots provide source for methane production, while oxygen delivered from the root aerenchyma enhances methane oxidation. Studies have shown that the diversity of these microorganisms depends on rice cultivars with some genes characterized as harboring specific groups of microorganisms related to methane emissions. However, there is still a need for research to determine the balance between methane production and oxidation, as rice plants possess the ability to regulate net methane production. Various agronomical practices, such as fertilizer and water management, have been employed to mitigate methane emissions. Nevertheless, studies correlating agronomic and chemical management of methane with productivity are limited. Moreover, evidences for breeding low-methane-emitting rice varieties are scattered largely due to the absence of coordinated breeding programs. Research has indicated that phenotypic characteristics, such as root biomass, shoot architecture, and aerenchyma, are highly correlated with methane emissions. This review discusses available studies that involve the correlation between plant characteristics and methane emissions. It emphasizes the necessity and importance of breeding low-methane-emitting rice varieties in addition to existing agronomic, biological, and chemical practices.

The grain 2AP content is strongly influenced by environmental and management factors during cultivation as well as post-harvest conditions. This review pinpointed the major abiotic and biotic factors that control grain 2AP content. Abiotic factors refer to water, temperature, light quality, fertilizer application (both macro- and micro-nutrients), and soil properties, including salinity, while biotic factors include microorganisms that produce aromatic compounds, thus influencing the grain aroma in fragrant rice. Post-harvest management, including storage and drying conditions, can significantly impact the grain 2AP content, and proper post-harvest conditions can intensify the grain aroma. This review suggests that there are rice varieties that can serve as potential sources of genetic material for breeding rice varieties with high grain aroma content.
