Dataset for: Homoploid F1 hybrids and segmental allotetraploids of rice subspecies are similarly more tolerant to N-deficiency than are parental lines

The study compared the phenotypic performance of two diploid rice subspecies indica and japonica (Oryza sativa L.) with the derived homoploid F1 hybrids (9N and N9) and segmental allopolyploids (99NN and NN99) under normal and low nitrogen conditions. Total gene expressions of 18 genes in critical growth-related pathways along with genotyping data by Sequenom MassARRAY of the plant groups were also analyzed to reveal the molecular rationale behind the morphological and physiological observations. The study shows that both hybridization and whole-genome duplication can confer rice better tolerance to low nitrogen conditions. The data were collected at the population level and fell into mainly 3 parts including i) phenotype (morphology and physiology) measurements of above and underground parts for the plant groups under normal and low-nitrogen conditions; ii) qRT-PCR quantification of the 18 involved genes by ΔΔCT method, and iii) genotyping dataset generated from Sequenom MassARRAY platform.The total expression of the gene "Chl-7" by qRT-PCR in 9N and N9 under N-limiting conditions were failed to be quantified; some other data points in total gene expression and genotyping datasets are missing.
