Summary: In this study, 36 expansin genes were identified in the Populus genome, and their molecular structure, chromosome localization, evolutionary relationships, and tissue specificity were analyzed. The study found that these genes were differentially expressed in different tissues and were closely associated with plant development and responses to phytohormone and abiotic stress. This study provides a basis for future functional research on the expansin gene family in Populus.

Summary: Long-term non-fertilization leads to minimal availability of nitrogen in the soil, which affects the yield and quality of tea. Lower nitrogen application promotes the biosynthesis of specific amino acids, including theanine and glutamate, while higher nitrogen application enhances flavonoid synthesis.

Summary: A study found that soybeans grown in western Canada have lower seed protein content compared to those grown in eastern Canada. Molecular biology and gene expression analysis revealed that this difference may be related to variations in key pathways such as amino acid metabolism and starch metabolism. Specifically, it was observed that western-grown soybeans had persistent upregulation of asparaginase and persistent downregulation of asparagine synthetase, and these enzymes were positively correlated with seed protein content and free asparagine in developing seeds.

Summary: Environmental or abiotic stresses pose a common threat to all plants, including rice, and studies have shown that salicylic acid (SA) plays a significant role in regulating abiotic stress in rice. However, the mechanisms behind this role are still unclear and further research is needed to understand the potential mechanisms controlling SA-mediated stress tolerance in rice.

Summary: Heat stress during the preflowering panicle initiation stage has a serious impact on rice grain weight by affecting physiological processes such as assimilate supply and phytohormone regulation. The effect of heat during this stage is more significant than during the grain-filling stage. Alterations in phytohormones caused by heat stress inhibit photosynthesis and carbohydrate accumulation, reducing grain size and plumpness. Understanding the molecular pathways underlying the reduction in grain weight during the panicle initiation stage is important.

Summary: In recent times, the demand for food and feed for the ever-increasing population has made it crucial to prevent crop yield loss. Abiotic stress in plants diverts energy needed for growth, leading to reduced plant yield. The application of phytohormones and nutrients can enhance plant tolerance to abiotic stress and improve metabolic activities.

Summary: Jujube is a valuable crop in South Korea, used for its medicinal and economic benefits. However, anthracnose caused by Colletotrichum spp. is a significant problem for jujube growers, leading to economic losses. In this study, two species of Colletotrichum, C. gloeosporioides sensu stricto and C. nymphaeae, were identified as the causal agents of anthracnose in jujube orchards. The isolates showed high sensitivity to azoxystrobin, highlighting its potential as a control measure. This study is also the first report of jujube anthracnose caused by C. nymphaeae in South Korea.

Summary: This study investigated the role of WRKY and bHLH transcription factors in cadmium stress tolerance in tomato. Genomic analysis revealed duplication events and gene loss in Arabidopsis and tomato during evolution. Transcriptomics analysis showed differential expression of WRKY and bHLH genes in response to cadmium stress and their involvement in stress-signaling pathways. These findings provide insights into the transcriptional control of WRKY and bHLH genes and have implications for improving stress-tolerant tomato varieties.

Summary: We identified a new quantitative trait locus (QTL) for lodging resistance in rice, specifically related to typhoon resistance. Through observation and analysis of a rice population's resistance to typhoons, we detected five QTLs for lodging resistance. The locus RM3343-RM20318 on chromosome 6, particularly the loci qTyM6 and qTyH6, exhibited significant effects on lodging resistance. Further analysis of the genes within this locus revealed potential candidates for improving lodging resistance. This study provides valuable insights into rice breeding and improving resilience to typhoons.

Summary: The gelatinization temperature of rice plays a crucial role in its eating and cooking quality, as well as consumer preference. Alkali digestion value (ADV) is a commonly used method to assess rice quality and is highly correlated with gelatinization temperature. This study utilized QTL analysis to identify genetic factors related to ADV in brown and milled rice. Through this analysis, 12 QTLs related to ADV were identified, and a screening of candidate genes in the chromosome 6 region resulted in the selection of 20 genes. Among these, OsSS1q6 showed a high expression level and has been found to interact with starch biosynthesis-related proteins. Therefore, OsSS1q6 may play a role in regulating the gelatinization temperature of rice through the control of starch biosynthesis. This study provides valuable insights for breeding high-quality rice and offers a new genetic resource for improving rice palatability.

Summary: Amino acids are crucial for plant species, such as rice, as they serve as the fundamental units of protein building blocks. This study aimed to investigate the amino acid profiles of four rice genotypes under NaCl, CaCl2, and MgCl2 stress. The results showed that the content of essential and non-essential amino acids significantly increased in cultivar Cheongcheong under NaCl and MgCl2 application, while total amino acid content increased in cultivar Nagdong under all three salt types. Salt-sensitive cultivar IR28 and salt-tolerant Pokkali exhibited lower levels of total amino acid content under different salt stress conditions. The findings suggest that the amino acid profile of each rice cultivar is influenced by its origin, immune level, and genetic makeup.

Summary: Rice is the main source of calories for the world's population, but the whitebacked planthopper (WBPH) is an insect that causes losses in rice yield. In this study, the possibility of using rice extracts (C7 and cq-9) as insect repellents was investigated. The results showed that C7 and cq-9 had low attraction for WBPH, and spraying them did not negatively affect plant height. This research is valuable for managing WBPH resistance and avoiding environmental pollution during rice cultivation.

Summary: Rice is a vital food source for most of the global population, but its yield is declining due to extreme climate change. Nitrogen fertilizers are commonly used by farmers to boost yield, but excessive application has negative effects on plants and the environment. Nitrogen fertilizer contributes to environmental pollution through the release of carbon monoxide, which reacts with greenhouse gases and affects global warming. This study focused on collecting carbon monoxide emissions from paddy fields after nitrogen fertilizer application. Adequate nitrogen fertilizer application can increase rice yield, but excess application negatively impacts grain quality and contributes to global warming through carbon monoxide emission.
