Genetic diversity of Prosopis juliflora in the state of Qatar and its valuable use against postharvest pathogen of mango fruits
( Nature Research , 2022 , Article)Mango (Mangifera indica) is the second most internationally traded tropical fruit in the world. The fruit has high nutritional value. Its susceptibility to postharvest diseases and chill injuries increases its storage cost ... -
Global patterns in endemicity and vulnerability of soil fungi
( Wiley , 2022 , Article)Fungi are highly diverse organisms, which provide multiple ecosystem services. However, compared with charismatic animals and plants, the distribution patterns and conservation needs of fungi have been little explored. ... -
The Global Soil Mycobiome consortium dataset for boosting fungal diversity research
( Springer , 2021 , Article)Fungi are highly important biotic components of terrestrial ecosystems, but we still have a very limited understanding about their diversity and distribution. This data article releases a global soil fungal dataset of the ... -
Hydropriming with moringa leaf extract mitigates salt stress in wheat seedlings
( MDPI , 2021 , Article)Salinity is the major constraint that decreases the yield and production of crops. Wheat has a significant value in agricultural food commodities. The germination and growth of wheat seedlings are a big challenge in ... -
Impact of ambient temperature, precipitation and seven years of experimental warming and nutrient
( Elsevier , 2021 , Article)Global change is causing changes in temperature, precipitation, and nutrient availability. Alpine and polar regions are predicted to be among the most vulnerable for these changes. We applied a seven-year factorial experiment ... -
