Graphical Abstract:


Salt stress is one of the main abiotic stresses that limits poplar (Populus spp.) growth and yields in many regions of the world. To cope with salt stress, poplars have evolved complex saltresponsive mechanisms in the proteomics level. Several proteomics-based studies have recently been conducted to characterize the molecular mechanisms in poplar. In this review, we summarize the effects of salt stress on the proteome of poplar. There are 84 salt-responsive proteins in poplar. These proteins are involved in a diverse range of reactions, including photosynthesis, scavenging of reactive oxygen species, carbon metabolism, energy metabolism, signal transduction, protein metabolism and disease resistance protein. These pathways play an important role in poplar under salt stress, with adjusts to the ability of salt tolerance. This review will likely contribute to a more thorough understanding of the different cellular activities in poplar exposed to salt conditions, with implications for the breeding of new poplar cultivars with improved traits.

Keywords: Protein, proteomics, poplar, reaction process, salt, stress.
