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 endophytes enhance the photoprotective mechanisms and photochemical efficiency in the Antarctic Colobanthus quitensis (Kunth) Bartl. Exposed to UV-B radiation
(2020)
Antarctic plants have developed mechanisms to deal with one or more adverse factors which allow them to successfully survive such extreme environment. Certain effective mechanisms to face adverse stress factors can arise ...
Maternal exposure to ozone modulates the Endophyte-conferred resistance to Aphids in lolium multiflorum plants
(2020)
Plants are challenged by biotic and abiotic stress factors and the incidence of one can increase or decrease resistance to another. These relations can also occur transgenerationally. For instance, progeny plants whose ...
Integration of physiological and molecular traits would help to improve the insights of drought resistance in highbush blueberry cultivars
(2020)
Water deficit or drought is one of the most severe factors limiting plant yield or fruit quality. Thus, water availability for irrigation is decisive for crop success, such as the case of highbush blueberry (Vaccinium ...
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 ...
A tradeoff between fitness‐related traits mask facilitation in a semiarid ecosystem
(2020)
In stressful environments, a nurse plant can ameliorate harsh biotic and abiotic conditions for another plant species that grows within its canopy. This canopy can act as a barrier for herbivores, reducing damage to the ...
Positive interaction between shrubs and native orchids in a Mediterranean ecosystem
(2020)
In the Mediterranean portion of Central Chile, where anthropic disturbances are common and severe, precipitations could drastically decrease and temperatures increase due to climate change. In this ecological context, ...
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 ...
A systematic review on the effects of Epichloë fungal endophytes on drought tolerance in cool-season grasses
(2021)
Symptomless fungal endophytes in the genus Epichloë are repeatedly mentioned to increase tolerance of cool-season grasses to a wide range of environmental stress factors, mainly drought. However, the generality of this ...
