Genotoxicity of oxidative stress and UV-B radiation in Antarctic vascular plants
(2021)
For plants, reactive oxygen species (ROS) and ultraviolet B radiation (UV-B) stand out as important genotoxic agents. Hence, the genetic damage among the Antarctic vascular flora, whose individuals frequently experience ...
Fungal symbionts enhance N-uptake for Antarctic plants even in non-N limited soils
(2020)
Plant-fungi interactions have been identified as fundamental drivers of the plant host performance, particularly in cold environments where organic matter degradation rates are slow, precisely for the capacity of the fungal ...
Root endophytic Penicillium promotes growth of Antarctic vascular plants by enhancing nitrogen mineralization
(2020)
Fungal endophyte associations have been suggested as a possible strategy of Antarctic vascular plants for surviving the extreme environmental conditions of Antarctica. However, the mechanisms by which this occurs are still ...
Symbiotic interaction enhances the recovery of endangered tree species in the fragmented maulino forest
(2021)
Beneficial plant-associated microorganisms, such as fungal endophytes, are key partners that normally improve plant survival under different environmental stresses. It has been shown that microorganisms from extreme ...
Functional roles of microbial symbionts in plant cold tolerance
(2020)
In this review, we examine the functional roles of microbial symbionts in plant tolerance to cold and freezing stresses. The impacts of symbionts on antioxidant activity, hormonal signaling and host osmotic balance are ...
Antarctic root endophytes improve physiological performance and yield in crops under salt stress by enhanced energy production and Na+ sequestration
(2020)
Climatic change is pointed as one of the major challenges for global food security. Based on current models of climate change, reduction in precipitations and in turn, increase in the soil salinity will be a sharp constraint ...
