When cultivated tobacco is crossed with a wild relative it erases lethal genes, allowing normally fatal hybrids to survive.

Researchers have identified 14 genes that thale cress express more when responding to five specific stressors, as well as eight genes that the plant suppresses.

Nitrogen is such a crucial nutrient for plants that vast quantities of nitrogen-containing fertilizers are spread on farmlands worldwide. However, excess nitrogen in the soil and in drainage run-off into lakes and rivers causes serious ecological imbalances. A recent study has uncovered the regulatory mechanisms at work when plants utilize nitrogenous fertilizers in their roots, a positive step in the quest to generate crops that require less fertilizer while still producing the yields needed to feed the world.

Researchers recently discovered the protein inhibiting the formation of organic nitrogen compounds in plants. This protein, if manipulated, could potentially be used to encourage plant growth and improve crop harvests.
