Replication data: Shallow rooting as a means of increased Zn-uptake by Zn-deficiency tolerant rice genotypes

Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Increased root numbers of rice genotypes have been attributed to its tolerance to Zn deficiency. However, its role in soil Zn uptake by plants and productivity in Zn deficient soils remains unclear. Here, we examined the  root numbers of rice genotypes (Zn-efficient, Zn-inefficient and popular variety) at different soil depths (soil surface, 0-2, 2-4 and 4 cm below) including their role in  soil Zn uptake , yield or productivity and grain Zn biofortification grown under Zn deficient soil at the IRRI experimental station. The root numbers at each soil depth [soil surface (P<0.05), 0-2 (P<0.01), 2-4 (P<0.0001) and below 4cm (P<0.001)] were significantly different among genotypes and the Zn-efficient (IR55179) genotype showed the highest root numbers among genotypes on the soil surface and at 0-2cm soil depth.
