Invertase PtrNINV1 and sucrose synthase PtrSUS1/2 positively regulate wood development by enhancing carbon supply in Populus trichocarpa

Shuang Zhang, Qiaoyi Zhang, Hongye Guo, Ruhui Chang et autres

Sucrose, the main carbon source for plant growth, is hydrolyzed by invertases (INVs) and sucrose synthases (SUSs), which are critical for carbon allocation and sink strength. However, their specific roles in xylem development in Populus remain unclear. Here, knockout mutants of PtrNINV1 …

PtrVINV2 is dispensable for cellulose synthesis but essential for salt tolerance in Populus trichocarpa Torr. and Gray

Shuang Zhang, Lina Cao, Danyang Chen, Ruhui Chang et autres

Invertase (EC.3.2.1.26), a key enzyme in sucrose breakdown, is crucial for cellulose synthesis. However, the function of the vacuolar invertase (VINV) in woody plants remains unclear. In this study, transgenic lines of Populus trichocarpa Torr. and Gray were generated to investigate the …

Overexpressing GLUTAMINE SYNTHETASE 1;2 maintains carbon and nitrogen balance under high-ammonium conditions and results in increased tolerance to ammonium toxicity in hybrid poplar

Xue Leng, Hanzeng Wang, Lina Cao, Ruhui Chang et autres

The glutamine synthetase/glutamic acid synthetase (GS/GOGAT) cycle plays important roles in N metabolism, growth, development, and stress resistance in plants. Excess ammonium (NH4+) restricts growth, but GS can help to alleviate its toxicity. In this study, the 84K model clone of hybrid …

Network Analysis of Metabolome and Transcriptome Revealed Regulation of Different Nitrogen Concentrations on Hybrid Poplar Cambium Development

Shuang Zhang, Lina Cao, Ruhui Chang, Heng Zhang et autres

Secondary development is a key biological characteristic of woody plants and the basis of wood formation. Exogenous nitrogen can affect the secondary growth of poplar, and some regulatory mechanisms have been found in the secondary xylem. However, the effect of nitrogen on …

Structure and Expression Analysis of PtrSUS, PtrINV, PtrHXK, PtrPGM, and PtrUGP Gene Families in Populus trichocarpa Torr. and Gray

Shuang Zhang, Wenjie Wang, Ruhui Chang, Jiajie Yu et autres

Exogenous nitrogen and carbon can affect plant cell walls, which are composed of structural carbon. Sucrose synthase (SUS), invertase (INV), hexokinase (HXK), phosphoglucomutase (PGM), and UDP-glucose pyrophosphorylase (UGP) are the key enzymes of sucrose metabolism involved in cell wall synthesis. To understand …

Identification and expression pattern analysis of PtCarA and PtCarB genes in Populus trichocarpa under different nitrogen treatments

Zhibao Hu, Shuang Zhang, H. Zhang, Leran Cao et autres

Carbamoyl phosphate synthetase (CPS) catalyses the synthesis of ammonia carbamoyl phosphate (CP), which plays a key role in the biosynthesis of arginine and pyrimidine nucleotides. There are two subunits of the CPS enzyme in Populus trichocarpa, CarA (small subunit) and CarB (large …
