Summary: This study successfully produced tobacco plants with A622 gene knockout using gene editing technology, and these mutant plants showed significantly reduced nicotine accumulation in field and greenhouse experiments. However, reducing A622 activity also resulted in significantly reduced growth and development of the plants.

Summary: Tobacco is a widely grown crop with high adaptability to different soils and climates. The chemical composition of tobacco leaves varies among different locations, which is important for the tobacco industry. This study evaluated the effect of variety, area, and cultivation period on the yield and content of nicotine, sugar, and nitrate in tobacco leaves. The results showed significant interactions between variety, area, and cultivation year on yield and nicotine content. Sugar content was significantly affected by all factors. The study also found that certain varieties showed better adaptation and higher yield in specific regions.

Summary: The study demonstrates that NtLTP4 plays a critical role in enhancing tobacco resistance to Ralstonia solanacearum by upregulating defense-related genes, enhancing antioxidant enzyme activity, and promoting stomatal closure. The interaction between NtLTP4 and WIPK, as well as their epistatic relationship, sheds light on the mechanisms underlying disease resistance in tobacco. This research provides valuable insights into the function of the WIPK-NtLTP4 module in enhancing plant tolerance to bacterial wilt disease in tobacco.

Summary: This research identified several tobacco introductions with low alkaloid phenotypes through phenotyping and genotyping analysis. Some introductions achieved lower alkaloid accumulation by deleting specific genes, while others achieved low alkaloid phenotypes through the deletion of another gene. In addition, a new genomic region that may affect alkaloid accumulation was discovered through quantitative trait locus mapping.

Summary: Leaf senescence in tobacco is regulated by the BAG family of proteins, with NtBAG5c and NtBAG6a-b being upregulated in senescent leaves. NtBAG5c interacts with heat-shock protein 70 (HSP70) and sHSP20, and its silencing reduces lignin content and affects superoxide dismutase (SOD) activity and hydrogen peroxide (H2O2) accumulation. Silencing NtBAG5c also downregulates the expression of senescence-related genes. This study provides the first identification and characterization of tobacco BAG protein candidate genes.

Summary: Leaf aging is a crucial process during herbaceous plant senescence, influenced by internal and external factors, with chlorophyll catabolism being a key metabolism pathway resulting in leaf yellowing. Proteomics techniques, such as iTRAQ-PRM, can help identify proteins related to photosynthesis showing differential expression during senescence in tobacco plants. This study provides valuable insights into the regulation of tobacco leaf senescence at the proteomics level.

Summary: The study found that adding tobacco biochar in karst regions can increase the organic matter and fertility element contents in soil, although it may lead to an increase in soil CO2 emissions. This increase in CO2 emissions is compensated by the higher tobacco productivity and reduced sulfur content. Additionally, tobacco biochar amendments also increase carbon storage in soil.
