A strategy for generating large numbers of peptides from a relatively small number of precursors based on photosynthetic combination in the gas phase is presented. In this approach, electrospray ionization is used to create a combination of proton-bound dimers from a specified set of peptides prese...
41 Even plant can run a fever, especially when they’re under attack by insects or disease. But unpke human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared(红外线)scanning technology developed for miptary purposes and other sa...
The relationships between CO2 assimilation rate and biochemical components of leaf photosynthesis, such as ribulose-bisphosphate (RuP2) carboxylase-oxygenase activity and electron transport capacity are examined and related to current theory of CO2 assimilation in leaves of C3 species. It w...
In the sea, photosynthesis by marine plants and algae, especially phytoplankton, removes great quantities of carbon dioxide from the atmosphere. Hence, the greater the growth (productivity) of phytoplankton in the sea, the greater the removal of carbon dioxide. But what controls the ocean ...
Climate change has been partially mitigated by an increasing net land carbon sink in the terrestrial biosphere; understanding the processes that drive this sink is thus essential for protecting, managing and projecting this important ecosystem service. I
10. This fraction of the visible light in the S2 treatments may have altered leaf photosynthesis; nonetheless, further studies are needed. Additionally, a < 1 °C shift in air temperature and < 5% change relative humidity with shading conditions may cause only a marginal effect in ...
