Web29 de abr. de 2024 · Nitrate transporter 2 (NRT2) plays an essential role in Nitrogen (N) uptake, transport, utilization, and stress resistance. In this study, the NRT2 gene family in two sequenced Brassica napus ecotypes were identified, including 31 genes in ‘Zhongshuang11’ ( BnaZSNRT2s) and 19 in ‘Darmor- bzh ’ ( BnaDarNRT2s ). Web1 de ago. de 2007 · Nitrate and ammonium present in the soil solution are the two major nitrogen sources for higher plants. Root nitrate influx is mediated by two distinct systems, the HATS and the LATS for the high- and low-affinity transport systems, respectively, operating when the external concentration of nitrate is below or above 1 mM [1].
