Plants and CO2 Uptake
Plants absorb carbon dioxide from the atmosphere. Exactly how fast this might occur is not clear. The capacity of terrestrial ecosystems to absorb carbon dioxide emissions from human activity may be greater than previously thought, according to a new study published in Nature Climate Change, which looks at how plants react to environmental change. The authors say these results improve our ...

Tobacco plants advertise their defensive readiness to attacking leafhoppers
Empoasca is not a typical pest of wild tobacco. When this plant grows in its natural habitats in North America, however, it is attacked by tobacco hornworm larvae. This specialist insect is resistant to the toxic nicotine, which the plant produces as a defense against its enemies. When researchers used particular transgenic plants in field experiments, they noticed that these plants were heavily ...

Deterring signals: Tobacco plants advertise their defensive readiness to attacking leafhoppers
Following herbivory, plants produce jasmonic acid, a hormone which activates several plant defense reactions. Scientists found that leafhoppers can evaluate whether tobacco plants are ready for defense when attacked. If jasmonate-signaling is activated, leafhoppers desist from feeding and test other plants. If the hormonal signaling system is dysfunctional, the herbivores start their attack. In ...

Plants could use light even more effectively for food production
Scientists have concluded that it is possible to develop plants that produce even more food by reducing the level of pigments which make no contribution to photosynthesis. The conclusion is based on research into the effectiveness of photosynthesis in various light conditions. The scientists discovered that leaf pigments not directly involved in photosynthesis ‘dissipate’ light by absorption ...
