Tomato spotted wilt virus (TSWV) is an economically important virus of flue-cured tobacco. Activation of systemic acquired resistance (SAR) by acibenzolar-S-methyl (ASM) in flue-cured tobacco was studied under greenhouse conditions by challenge inoculation with a severe isolate of TSWV. ASM restricted virus replication and movement, and as a result reduced systemic infection. Activation of resi...

EXECUTIVE SUMMARY This document serves as a DOE post-project assessment of a project in Round 3 of the Clean Coal Technology (CCT) Demonstration Program titled, "Demonstration of SO 2 Removal Using Gas Suspension Absorption Technology." In October 1990, AirPol Inc. entered into a cooperative agreement to conduct the study, with the Tennessee Valley Authority (TVA) as the host and co-sponsor. Th...

A variant designated "cherry-red" is frequently observed in common flue-cured tobacco varieties. This variant has a dappled red coloration of the cured leaf. Cherry-red and red-free selections have been obtained from Nicotiana tabacum, L. cv. 401. Analysis of these selections for alkaloids showed that the cherry-red selection had a much higher nornicotine content than the red-free selection. Co...

In the article entitled " Economic and energetic analysis of capturing CO 2 from ambient air, " House et al. (1) drew an analogy between air capture and other gas separation processes. It concludes that (i) " unless air capture significantly outperforms these systems, it is likely to require more than 400 kJ of work per mole of CO 2 " and (ii) " costs of air capture systems will be on the order...

Abstract The composition and content of aroma substances in flue-cured tobacco ( Nicotiana tabacum L.) will affect the quality tobacco. To investigate correlation between various K326 before after flue-curing, their impact on diversity, this study employed middle leaves KRK26 as test materials. Samples were collected both flue-curing for untargeted metabolomics analysis. results showed that 584...

BACKGROUND Topping is an important cultivating measure for flue-cured tobacco, and many genes had been found to be differentially expressed in response to topping. But it is still unclear how these genes are regulated. MiRNAs play a critical role in post-transcriptional gene regulation, so we sequenced two sRNA libraries from tobacco roots before and after topping, with a view to exploring tran...
