Transformation of HBsAg (hepatitis B surface antigen) gene into tomato mediated by Agrobacterium tumefaciens

Czech Journal of Genetics and Plant Breeding, 2011
The plant expression vector pBRSAg was constructed as suitable for transformation via Agrobacterium-mediated approach. It contains all elements for plant expression, such as CaMV 35S promoter, both left and right border sequence for transferred DNA (T ...

Response of soil carbon fractions and enzyme activities to mowing management on in a coastal wetland of the yellow river delta

Frontiers in Marine Science, 2022
Coastal wetlands are considered as important “blue carbon” sink, and mowing management induced by anthropogenic activities is anticipated to profoundly affect soil carbon stocks in coastal wetlands.

Effect of Wetland Restoration and Degradation on Nutrient Trade-Off of Carex schmidtii

Frontiers in Ecology and Evolution, 2022
Plant nutrient trade-off, a growth strategy, regulates nutrient stoichiometry, allocation and stoichiometric relationships, which is essential in revealing the stoichiometric mechanism of wetland plants under environmental fluctuations.

Soil Microbes from Saline–Alkali Farmland Can Form Carbonate Precipitates

Agronomy, 2023
The formation of soil inorganic carbon in saline–alkali lands is of great significance for enhancing soil carbon sequestration. As for the formation mechanisms, in addition to the discovered abiotic mechanisms, the microbial mechanisms remain unclear. To

Increase in Soil Carbon Pool Stability Rather Than Its Stock in Coastal Saline—Alkali Ditches following Reclamation Time

Agronomy, 2023
Extensive drainage ditches are constructed to reduce soil salinity in reclaimed saline–alkali farmland, consequently forming plant growth hotspots and impacting soil carbon stocks therein.

Influence of Gate Dams on Yellow River Delta Wetlands

Land, 2022
Nested Delft 3D and Hydrus 1D models were applied to simulate variations in the hydrological process of tidal creeks, soil water, and salt transport in the soil profile of the reconstruction area in the Yellow River Delta under six gate dam scenarios.

Wetland Landscape Pattern Evolution and Prediction in the Yellow River Delta [PDF]

Applied Water Science, 2021
Abstract Starting from the overall pattern of wetland evolution in the Yellow River Delta, The combination of CA-Markov model and MLP model is studied. Based on the low-medium resolution Landsat data and the field survey data, the evolution trend of wetland landscape pattern in the Yellow River Delta is simulated and predicted by using the ...
