Circumventing boron toxicity to ensure enhanced yield of wheat in Australia

Circumventing boron toxicity to ensure enhanced yield of wheat in Australia

In the 3rd July, ‘14  issue of Nature wheat breeders at  the Australian Centre for Plant Functional Genomics at the University of Adelaide’s Waite campus have reported that they have identified the genes in wheat that control boron tolerance  significantly. This discovery will help wheat breeders advance more rapidly new varieties for increased yields to help feed the growing world population. It may be mentioned here that productivity is limited by many factors such as drought, salinity, subsoil constraints such as  boron toxicity. The presence of too high levels of boron is  a global problem. This can be mitigated by breeding boron tolerant lines of wheat because boron tolerant  lines can maintain good root growth. The concerned molecular breeders think that they have identified genes responsible for adaptation to boron toxicity which affect more than 30% of soils in Australia and is considered to be a  global problem. It may be mentioned here that boron tolerant lines of wheat can maintain good root growth in boron toxic soils whereas intolerant lines suffer from  stunted roots.
