Data for "Ozone-tolerant rice for air-polluted environments"

Description of dataset This dataset provides data from a project aimed at breeding of ozone tolerant rice lines. The lines were developed by introgressing previously reported ozone tolerance QTL (Frei et al. 2008) into the Bangladeshi elite rice varieties BINA dhan11 and BRRI dhan 28. The genetic markers and genotypes of the resulting lines are documented in the file ‘Sequence and Genotyping’. The different lines were then tested in a greenhouse experiment and field experiment (ozone concentrations, see file ‘Ozone data’). The remaining files present physiological and morphological data of the different breeding lines under control and high ozone conditions. Abbreviations - O3 = ozone - ppm = parts per million - ppb = parts per billion - KASP = Kompetitive Allele-Specific PCR - LBS = leaf bronzing score - NDVI = normalized difference vegetation index - Lic2 = Lichtenthaler index 2 (representing carotenoid/chlorophyll ratio) - SC = stomatal conductance - PhiPS2 = Quantum efficiency of photosystem 2 of light adapted leaves - A = CO2 assimilation rate - MDA = malondialdehyde References - Frei M, Tanaka JP, Wissuwa M (2008) Genotypic variation in tolerance to elevated ozone in rice: dissection of distinct genetic factors linked to tolerance mechanisms.
