Other claims from this paper (12)
- Observation OsNAR2.1 was mainly expressed in root epidermal cells, unlike the five OsNRT2 genes.
- Intervention effect Nitrate up-regulated OsNAR2.1, OsNRT2.1, OsNRT2.2 and OsNRT2.3a.
- Intervention effect NH(4)(+) suppressed OsNAR2.1, OsNRT2.1, OsNRT2.2 and OsNRT2.3a.
- Intervention effect High root temperature of 37 °C suppressed OsNAR2.1, OsNRT2.1, OsNRT2.2 and OsNRT2.3a.
- Intervention effect Light increased expression of these nitrate-transporter genes.
- Intervention effect External sugar supply increased expression of these genes.
- Observation Root transcripts of OsNRT2.3b and OsNRT2.4 were much less abundant.
- Intervention effect Temperature did not affect root transcripts of OsNRT2.3b and OsNRT2.4.
- Intervention effect OsNRT2.3b expression was insensitive to nitrogen-supply form.
- Intervention effect OsNRT2.4 expression responded to auxin supply unlike other NRT2 genes.
- Mechanism The OsNAR2.1 promoter region -311 to -1 contained elements necessary for nitrate-dependent activation, but not light- or sugar-dependent activation.
- Observation A conserved cis-element was difficult to define in nitrate-regulated OsNRT2/OsNAR2 promoters.
