Agriculture:

Drought-resistant plant genes could accelerate evolution of water-efficient crops — Oak Ridge National Laboratory
Scientists at the Department of Energy have identified a common set of genes that enable different drought-resistant plants to survive in semi-arid conditions, which could play a significant role in bioengineering and creating energy crops that are tolerant to water deficits.

Thin tidings: Christmas tree supply tightening as demand increases — AgWeek
