Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. Botanists have demonstrated that it is based on the activity of a certain factor, ...

More than 95% of container-grown longleaf pine (Pinus palustris P. Mill.) seedlings had roots growing downward vertically (geotropically) when examined 7 to 8 mo after transplanting into sand.
