tobacco plants spreads via something smaller than a bacterium.
And they took us deep into the natural world, as we invited scientists to consider what makes ecosystems on land and water resilient, and explored how organisms as diverse
as tobacco plants and bacteria have evolved resilience strategies that offer lessons — or at least metaphors — we humans could embrace.

young tobacco plants and a protein expression system to make and harvest the proteins in the leaves.
After 2 days at 47 °C — comparable to summer in the Sahara —
normal tobacco plants withered and died, but the transgenic plants survived.
Scientists have tried to re-create the effect in plants before: In the 1980s, researchers added a firefly's luciferase gene into
tobacco plant cells.
Genetically modified
tobacco plants turn on photosynthesis faster when shade follows dangerous sunlight
The most recent breakthrough was made by a team of British and American biologists who report they've successfully
infused tobacco plants with bacterial genes — a first step towards engineering crops that grow faster, offer higher yields and use less fertilizers.
We found approximately 69 % of the transgenic
tobacco plants responded to the ligand (Table S1), typical for transgenic plants requiring expression of two T - DNAs.
Two of the modified plant lines tested showed 20 percent higher productivity, and the third showed a 14 percent increase, compared to the
unaltered tobacco plants.

from tobacco plants and is thought to have an anti-inflammatory effect.
Genetically
engineered tobacco plants, chosen to test the concept, managed the unusual feat of growing 14 to 20 percent more mass — meaning more crop yield — than untweaked plants, says Krishna Niyogi of the University of California...
Transgenic tobacco plants in which the gene encoding chloroplast omega - 3 fatty acid desaturase, which synthesizes trienoic fatty acids, was silenced contained a lower level of trienoic fatty acids than wild - type plants and were better able to acclimate to higher temperatures.
He used this genetically altered version as a Trojan horse to implant the protein
into tobacco plants, which could then manufacture their own pesticides.
He focused first on haemophilia B. Adapting a technique that he had previously developed to delay the onset of type 1 diabetes, Daniell and his group genetically
