Transcriptome and metabolome analyses reveal molecular mechanisms of anthocyanin-related leaf color variation in poplar () cultivars.

Introduction: Colored-leaf plants are increasingly popular for their aesthetic, ecological, and social value, which are important materials for research on the regulation of plant pigments. However, anthocyanin components and the molecular mechanisms of anthocyanin biosynthesis in colored-leaf poplar remain unclear. Consequently, an integrative analysis of transcriptome and metabolome is performed to identify the key metabolic pathways and key genes, which could contribute to the molecular mechanism of anthocyanin biosynthesis in the colored-leaf cultivars poplar.

Pancreatic necrosis and severity are independent risk factors for pancreatic endocrine insufficiency after acute pancreatitis: A long-term follow-up study.

Background: Pancreatic endocrine insufficiency after acute pancreatitis (AP) has drawn increasing attention in recent years.

Aim: To assess the impact of risk factors on the development of pancreatic endocrine insufficiency after AP.

Methods: This retrospective observational long-term follow-up study was conducted in a tertiary hospital.

A putative soybean GmsSOS1 confers enhanced salt tolerance to transgenic Arabidopsis sos1-1 mutant.

The cDNA of GmsSOS1, a putative plasma membrane Na(+)/H(+) antiporter gene isolated from Glycine max, Glycine soja, and their hybrid, was constructed into plant expression vector pCAMBIA 1300 and then transformed with Agrobacterium tumefaciens under the control of CaMV 35S promoter to Arabidopsis thaliana wild-type (WT) and mutant (atsos1-1) plants. By hygromycin resistance detection and PCR analysis, transgenic plants (WT35S:GmsSOS1 and atsos1-1 35S:GmsSOS1) were obtained. Seed germination, seedling growth, and Na(+) contents in roots and shoots were analytically compared among WT, atsos1-1 mutant, and their transgenic lines under salt stress.

Ionic effects of Na+ and Cl- on photosynthesis in Glycine max seedlings under isoosmotic salt stress.

Ion-specific stress effects of Na(+) and Cl(-) on photosynthesis of seedlings of two soybean (Glycine max) cultivars (the salt-tolerant 'Lee68' and the salt-sensitive 'N23674') were studied and compared under isoosmotic (-0.53 MPa) solutions [PEG-6000, NaCl, Na(+) (without Cl(-)) and Cl(-) (without Na(+))] for 6 d. The results showed that the chlorophyll contents and the ribulose bisphosphate carboxylase/oxygenase (Rubisco) activities of seedlings of both cultivars were inhibited to a less degree by PEG-6000 than by NaCl, Na(+) (without Cl(-)) or Cl(-) (without Na(+)) solutions.

[Relationship between chloride tolerance and polyamine accumulation in Glycine max, Glycine soja, and their hybrid seedlings].

The seedlings of the F4 hybrid strain 'JB185' selected for salt tolerance generation by generation, their parents Glycine max cv. Jackson and Glycine soja population 'BB52' were treated with different NaCl concentrations and iso-osmotic (-0.53 MPa) PEG-6000, NaCl, Na+ (without Cl-) and Cl- (without Na+) solutions for 6 d.

Effects of salinity on activities of H+ -ATPase, H+ -PPase and membrane lipid composition in plasma membrane and tonoplast vesicles isolated from soybean (Glycine max L.) seedlings.

The effects of NaCl stress on the H+ -ATPase, H+ -PPase activity and lipid composition of plasma membrane (PM) and tonoplast(TP) vesicles isolated from roots and leaves of two soybean cultivars (Glycine max L.) differing in salt tolerance (Wenfeng7, salt-tolerant; Union, salt-sensitive) were investigated. When Wenfeng7 was treated with 0.

Tonoplast H+-ATPase activity in barley roots is regulated by ATP and pyrophosphate contents under NaCl stress.

The changes in ATP and PPi contents in roots under NaCl stress, and the effect of PPi on tonoplast H(+)-ATPase activity were studied with two barley cultivars differing in salt tolerance. The results showed that tonoplast H(+)-ATPase activity in salt-tolerant barley cultivar "Tanyin 2" roots increased obviously under NaCl 200 mmol/L (containing half-strength Hoagland solution) for 2 d, and decreased gradually. Tonoplast H(+)-PPase activity always decreased under NaCl stress.
