But before they can do this, they need to understand more about which genes are responsible for the changes in a plant's growth
rate under drought conditions.
The company is currently testing a variety of GM corn in the U.S. that can produce up to 10 % more
yield under drought conditions than corn without the modification.
Before this study — the largest of its kind — conducted by a team led by Professor Dirk Inzé, scientists had little insight into the genes and genetic processes that drive some plants to limit their growth
under drought conditions while others grow normally.
The drought sensitive cultivar» 1110» benefited from the AM
fungi under drought conditions, resulting in increased biomass, improved photosynthesis and improved nitrogen - use.
In March, the monsoon is not present, meaning low water flows in the Ganges under normal conditions, and even less
so under drought conditions such as this year.
Even though these gains were substantially less than runoff gains during pluvials, additional
runoff under drought conditions could help lessen the impact of predicted climate - driven losses in hydrologic connectivity important to native fish in the Salt and Verde watersheds [64].
«First and foremost, we found that corn and soybean yields were the same across the three systems,» said Pimentel, who noted that although organic corn yields were about one - third lower during the first four years of the study, over time the organic systems produced higher yields,
especially under drought conditions.
Under drought conditions and without useful AM fungi, the drought tolerant wheat cultivar performed better.
CAM plants are unique in
that under drought conditions their stomates (leaf pores) are open at night rather than during the day (as is the case with most plants).
