Functional Descriptions:
- PuHox52 promotes coordinated uptake of nitrate, phosphate, and iron under nitrogen deficiency in Populus ussuriensis.
- Functionally characterized PuHox52, a Populus ussuriensis HD-ZIP transcription factor, whose overexpression greatly enhanced nutrient uptake and plant growth under N deficiency.
- PuHox52 was specifically induced in roots by N deficiency, and overexpression of PuHox52 promoted N uptake, plant growth, and root development.
- Our results revealed that PuHox52 directly regulates a master nitrate-responsive gene, PuNRT1.1, two key phosphate-responsive genes, PuPHL1A and PuPHL1B, and an iron transporter gene, PuIRT1, after N deprivation, thereby coordinately regulating nitrate, phosphate, and iron uptake under low N condition. These results, taken together, unraveled novel multifaceted roles of PuHox52 in enhancing nutrient uptake under N deficiency in P. ussuriensis.
- PuHox52-mediated hierarchical multilayered gene regulatory network promotes adventitious root formation in Populus ussuriensis.
- PuHox52 is rapidly induced by cutting and promotes AR formation at the basal ends of in vitro stem cuttings of P. ussuriensis.
