Rapid deforestation of a coastal landscape driven by sea level rise and extreme events.

Ecol Appl 2021 Apr 4:e2339. Epub 2021 Apr 4.

Department of Biology, Duke University, Box 90338, Durham, North Carolina, 27708, USA.

Climate change is driving ecological shifts in coastal regions of the world, where low topographic relief makes ecosystems particularly vulnerable to sea level rise, salinization, storm surge, and other effects of global climate change. The consequences of rising water tables and salinity can penetrate well inland, and lead to particularly dramatic changes in freshwater forested wetlands dominated by tree species with low salt tolerance. The resulting loss of coastal forests could have significant implications to the coastal carbon cycle. Read More

Int J Mol Sci 2021 Mar 19;22(6). Epub 2021 Mar 19.

Department of Life Sciences, National Chung Hsing University, Taichung 40227, Taiwan.

To date, soil salinity becomes a huge obstacle for food production worldwide since salt stress is one of the major factors limiting agricultural productivity. It is estimated that a significant loss of crops (20-50%) would be due to drought and salinity. To embark upon this harsh situation, numerous strategies such as plant breeding, plant genetic engineering, and a large variety of agricultural practices including the applications of plant growth-promoting rhizobacteria (PGPR) and seed biopriming technique have been developed to improve plant defense system against salt stress, resulting in higher crop yields to meet human's increasing food demand in the future.

Cells 2021 Mar 6;10(3). Epub 2021 Mar 6.

Biosciences Division, Oak Ridge National Laboratory, Oak Ridge, TN 37831, USA.

It has been challenging to simultaneously improve photosynthesis and stress tolerance in plants. Crassulacean acid metabolism (CAM) is a CO-concentrating mechanism that facilitates plant adaptation to water-limited environments. We hypothesized that the ectopic expression of a CAM-specific phosphopyruvate carboxylase (PEPC), an enzyme that catalyzes primary CO fixation in CAM plants, would enhance both photosynthesis and abiotic stress tolerance.

Prunus Hexokinase 3 genes alter primary C-metabolism and promote drought and salt stress tolerance in Arabidopsis transgenic plants.

Sci Rep 2021 Mar 29;11(1):7098. Epub 2021 Mar 29.

Instituto de Investigaciones Agropecuarias CRI Rayentué, Av. Salamanca s/n, Sector Los Choapinos, Rengo, Chile.

Hexokinases (HXKs) and fructokinases (FRKs) are the only two families of enzymes in plants that have been identified as able to phosphorylate Glucose (Glc) and Fructose (Fru). Glc can only be phosphorylated in plants by HXKs, while Fru can be phosphorylated by either HXKs or FRKs. The various subcellular localizations of HXKs in plants indicate that they are involved in diverse functions, including anther dehiscence and pollen germination, stomatal closure in response to sugar levels, stomatal aperture and reducing transpiration.
