An Econometric Model of the Tobacco Industry [PDF]

The Review of Economics and Statistics, 1969
N thi's paper we describe an econometric model of the American tobacco industry for the period 1949 through 1966. The model contains 19 equations and is divided into three major blocks (1) leaf production, (2) leaf price, and (3) cigarettes. The objective is to explain the behavior of the tobacco industry over an 18-year period.

Returning ryegrass to continuous cropping soil improves soil nutrients and soil microbiome, producing good-quality flue-cured tobacco

Frontiers in Microbiology, 2023
The widespread and continuous cultivation of tobacco has led to soil degradation and reduced crop yields and quality. Green manure is an essential organic fertilizer that alleviates obstacles to continuous cultivation.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Root exudate monosaccharides modulate the pathogenicity of Ralstonia pseudosolanacearum

Frontiers in Microbiology
The Ralstonia solanacearum species complex (RSSC) is a devastating soil-borne pathogen that causes bacterial wilt in solanaceous crops. However, the response of RSSC to monosaccharides—key components of root exudates released into the rhizosphere—remains
