Plants sense water in soil to grow roots in the right direction

Scientists have discovered how the presence of even small amounts of water can influence the structure of plant roots in soil, a finding that opens up new possibilities to improve water and nutrient foraging for important food crops. Significant improvements in crop yields are urgently required to meet the 50% increase in world population by 2050. The degree of root branching determines...

Selecting for plants with thinner roots could improve drought tolerance

Plants with thinner roots can grow deeper, a trait which could be exploited in lands affected by drought and nutrient deprivation. New research, to be presented at the Society for Experimental Biology meeting on July 5, shows that maize roots which have fewer cortical cells in the outer layer of their roots are more efficient at accessing water and nutrients. A research team headed by...
