Genetic Engineers Aim to Soup Up Crop Photosynthesis

Article Abstract:

Genetic engineers are trying to enhance photosynthesis of crops by altering the enzyme ribulose-1,5-bisphosphate carboxylase-oxygenase, or RuBisCO. This enzyme is the main catalyst of photosynthesis, but is one of the slowest enzymes of all. Scientists are hoping to increase the pace of photosynthesis by adding the more effective RuBisCO of red algae or molecular superchargers to the normal enzyme.

A Species' Fate, By the Numbers

Article Abstract:

Population viability analysis is a technique used to predict the possible fates of populations of threatened animals. The technique was developed over 20 years ago and a 1999 conference on PVA attracted 330 scientists. Problems discussed included possible misuse of PVA software, refining the technique, and including human influence in the models.

Crop Scientists Seek a New Revolution

Article Abstract:

Scientists will have to discover a way of increasing the productivity of grain crops to accomodate the forecasted 40% increase in demand by the year 2020. Farmers are producing grain at record levels already, so that scientists must find a way for the farmers to increase capacity to grow the grain through genetic engineering.
