In uranium leaching, Acidophillus ferrooxidans oxidizes U4+ to U6+ with O2 as an electron acceptor. 

However, Uranium leaching depends more on the abiotic oxidation of U4+  by Fe3+ with A. ferrooxidans contributing to the process mainly through the reoxidation of Fe2+ to Fe+3, as in copper leaching.

R gene Mi-1 confers resistance to aphids and whiteflies

Rice R gene Bph14 confers resistance to the brown plant hopper

Melon R gene Vat confers resistance to the cotton aphid. 

All of these R genes encode NBS–LRR receptors.
