Identification of the sucrose phosphate synthase (SPS) gene family reveals the positive role of NtSPS5 and NtSPS6 in drought stress tolerance of tobacco

Chemical and Biological Technologies in Agriculture
Background Sucrose phosphate synthase (SPS) is an important enzyme in the sucrose synthesis of plants, governing the accumulation and distribution of photosynthetic assimilates, which is essential for plant growth and stress tolerance. Results This study

Demand Analysis under Price Rigidity and Endogenous Assortment: An Application to China's Tobacco Industry [PDF]

arXiv
We observe nominal price rigidity in tobacco markets across China. The monopolistic seller responds by adjusting product assortments, which remain unobserved by the analyst. We develop and estimate a logit demand model that incorporates assortment discrimination and nominal price rigidity.

Histopathological study on goldfish (Carassius auratus) gonads exposed to tobacco smoke [PDF]

arXiv
Ornamental fish have various positive effects in human life. Due to the effect and importance of aesthetics and artificial reproduction of these fish, which may be enclosed in aquarium environments and come in contact with cigarette smoke, the effects of tobacco smoke on the gonad tissue of goldfish were investigated.

Regression prediction of tobacco chemical components during curing based on color quantification and machine learning

Scientific Reports
Color is one of the most important indicators to characteristic the quality of tobacco, which is strongly related to the variations of chemical components. In order to clarify the relationship between the changes of tobacco color and chemical components,
