Signals for Survival
If plants had brains, they'd be single-minded, indeed. Their mantra would be
"survive and reproduce." But plants don't use, or express, many of their genes
until absolutely necessary, such as when they are under stress. The ability of
genes to hibernate saves precious energy, says IPG member Shuqun Zhang, associate professor
of biochemistry. Zhang has recently earned high praise in the scientific community
for his studies of the complex internal signals plants send when they are
subject to stress, including extreme heat or cold, viruses or ultraviolet
light.
Fighting Malnutrition in Africa
Each day, hundreds of millions of people suffer with disease, blindness and
other problems associated with malnutrition. Now, one IPG member has joined an international consortium in an effort
to improve the nutritional value of sorghum, a staple of the African diet,
as one way to combat this problem.
Understanding How Plants Bend Toward Blue Light
Plants need light and water to grow. These necessities, however, are not always
readily accessible. While plants may not be able to move to a better location,
they do have the ability to orient their leaves, stems, and roots to optimize
their access to light and water. IPG member Mannie Liscum and his lab are using various genetic approaches to understand how plants bend toward blue light.
