    Boron toxicity, a widely observed abiotic stress, affects the yield and quality of the crops especially in arid and semi-arid agricultural regions. The biggest challenge in dealing with B toxicity is the genetic variation in plants. Puccinellia distans (Jacq.) Parl., a boron toxicity tolerant grass species, is found to endure extremely high Boron concentrations. We have conducted different experiments on Puccinellia species to reveal possible aspects of its B toxicity tolerance. We estimated the physiological, biochemical and chemical changes in Puccinellia under Boron toxicity; outcomes of transcriptomics and expression analysis highlights its interlink with several biological processes. B toxicity is often associated with salt stress; in one of our experiments, characterization of B and Na efflux proteins directs towards B uptake and transport in plants roots that may have major role in maintaining plant homeostasis. We are also trying to determine the association between Puccinellia species and mycorrhizae that may have a significant role in soil reclamation. New crop development processes conducted by the breeders may further be empowered by novel B toxicity tolerant resources acquired from the knowledge gained from the detailed screening of P. distans species.
