Two small molecules that are produced by the plant Arabidopsis thaliana are shown to have the opposite effect on how fast its leaves age. The molecules are peptides, short chains of amino acids.
Using a computer model that reveals how plants grow thicker over time, biologists have uncovered how cells are activated to produce wood tissue. Understanding the genetic and molecular signals behind ...
For example, plants need boron, which is taken into the ... University's Graduate School of Agriculture identified a mutant line of Arabidopsis thaliana in which the boric acid channels are ...
