Majority of the genotypes showed adaptive responses to low P condition. Based on phenotype behaviour using the best linear unbiased predictors for each trait, genotypes were classified into, P responsive, low P tolerant and P non-responsive types. Based on the overall phenotype performance under Pdef, 10 genotypes were identified as low P tolerants. The low P tolerant genotypes were characterised by increased shoot and root length and increased root hair induction with longer root hairs under Pdef, than under Psuf. Association mapping of P response traits using mixed linear models revealed four quantitative trait loci (QTLs). Two QTLs (qLRDW.1 and qLRDW.2) for low P response affecting root dry weight explained over 10% phenotypic variation. In silico synteny analysis across grass genomes for these QTLs identified putative candidate genes such as Ser-Thr kinase and transcription factors such as WRKY and basic helix-loop-helix (bHLH). The QTLs for response under Psuf were mapped for traits such as shoot dry weight (qHSDW.1) and root length (qHRL.1). Putative associations of these QTLs over the syntenous regions on the grass genomes revealed proximity to cytochrome P450, phosphate transporter and pectin methylesterase inhibitor (PMEI) genes. This is the first report of the extent of phenotypic variability for P response in finger millet genotypes during seedling-stage, along with the QTLs and putative candidate genes associated with P starvation tolerance.","2017-08-18","published",,"PLoS ONE",,,"Public Library of Science",,"1-27",,,,,,"10.1371/journal.pone.0183261",,,,,"TRUE",,"1932-6203",,,,,,"","http://dx.doi.org/10.1371/journal.pone.0183261","https://scholar.google.co.in/scholar?hl=en&as_sdt=0%2C5&q=%3A+Identification+of+putative+QTLs+for+seedling+stage+phosphorus+starvation+response+in+finger+millet+%28Eleusine+coracana+L.+Gaertn.%29+by+association+mapping+and+cross+species+synteny+analysis&b","pub",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
