SCIENTIFIC REPORTS, 11(1).

By: J. Lu n, N. Chandrakanth  n, R. Lewis n , K. Andres n, L. Bovet*, S. Goepfert *, R. Dewey n

MeSH headings : Biomass; Environment; Flowers / genetics; Gene Expression Regulation, Plant; Gene-Environment Interaction; Genetic Association Studies; Nitrate Reductase / genetics; Nitrate Reductase / metabolism; Organ Specificity / genetics; Plant Development / genetics; Tobacco / physiology; Transcriptional Activation
TL;DR: It is shown that plants expressing a constitutively active NR construct, designated 35S:S523D-NR, display an early-flowering phenotype that is also associated with a substantial reduction in plant biomass, and the mechanism by which yield was restored differed markedly between the two crosses.

Transgenic and Mutation-Based Suppression of a Berberine Bridge Enzyme-Like (BBL) Gene Family Reduces Alkaloid Content in Field-Grown Tobacco

PLOS ONE, 10(2).

By: R. Lewis n , H. Lopez n, S. Bowen n, K. Andres n, W. Steede n & R. Dewey n

MeSH headings : Alkaloids / biosynthesis; Alkaloids / chemistry; Gene Expression Regulation, Plant; Mutation; Plant Proteins / antagonists & inhibitors; Plant Proteins / genetics; Plant Proteins / metabolism; Plants, Genetically Modified / genetics; Plants, Genetically Modified / metabolism; RNA Interference; Tobacco / genetics; Tobacco / growth & development; Tobacco / metabolism
TL;DR: Transgenic doubled haploid lines of tobacco cultivar K326 carrying an RNAi construct designed to reduce expression of the BBL gene family were produced, indicating that a range of alkaloid phenotypes could be produced, with the triple homozygous knockout genotype exhibiting greater than a 13-fold reduction in percent total alkaloids.
