Abstract The European black poplar (Populus nigra L.) has been used as a
germplasm resource for the breeding of new poplar varieties around the world. The
identification and screening of its high nitrogen use efficiency genotypes could
enable the breeding of new resource-efficient poplar varieties. The accessions were
screened using MALDI-TOF MS genotyping technology for ammonium
transporter (AMT) and nitrate transporters (NRT) genes against phenotypic data for
seedling height and ground diameter traits, in both low and high nitrogen
environments. Allele re-sequencing of seven genes related to root development
was carried out using the minisequencing method. By cluster… More >
