Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. An international team of plant biologists has demonstrated that it is based on the ...

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.

The outcome was that no more lateral roots were formed. This result was confirmed by another experiment in which the two biologists treated either the leaves or the roots in the dark with a solution ...

Scientists identify genes affecting root length that could make it easier to breed drought-resistant wheat. Wheat is a key crop for ensuring global food security, but drought associated with climate ...
