Dr. George Karlin-Neumann, Stanford University. Microarray experiments
like this one allow a global analysis of gene expression in plants responding
to different stimuli such as temperature, drought or pathogen attack.
The information gained from this type of study will be essential for
researchers to zero in on the groups of genes that work together to
modulate particular plant responses. Many of these responses are of
agricultural importance. Microarray analysis is thus going to be an
important part of the design of tomorrow's crops.
