Biologists identify chemicals affecting plant growth in response to gravity
A team of biologists from the University of California, Riverside has used chemical genomics to identify novel compounds that affect the ability of plants to alter their direction of growth in response to gravity, a phenomenon known as gravitropism.
The researchers screened a library of 10,000 small molecules, the practice is known as chemical genomics, to identify those that could positively or negatively affect gravity’s effect on plant growth, which is closely linked to the movement of proteins through plant cell membranes, a process known as endomembrane trafficking. “Well-characterized bioactive chemicals and their targets identified in the model plant, Arabidopsis, can be used in non-model species to improve agronomic traits and increase crop value,” said research team leader, Distinguished Professor of Plant Cell Biology Natasha Raikhel.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
