Many commercial crops are susceptible to natural stresses — diseases, insects, drought, temperature extremes — and genes from tougher wild relatives can make them more robust.
The seeds are a source of genetic diversity critical as farmers look for plants to withstand climate change and develop new varieties better adapted for drought, temperature extremes, salinity and disease.
Over this next decade and the decades to come, being able to develop varieties of crops that are more resilient to drought, temperature and other weather events is going to be a big challenge for us, but one that I also think there is a good likelihood that we'll be able to deliver for the farmers.
While rising atmospheric CO2 levels could provide benefits to mediterranean plant species [34], the effects are altered when multiple factors of change are considered, including fire, drought, temperature increase, nitrogen deposition, and invasive species [35] [38].
Curcin 2 was isolated from leaves that had been subjected to drought, temperature, and fungal infection stresses [ 57], suggesting a role in plant defense.
In such periods, rhizobial cells are exposed to the action of environmental factors such as nutrient limitation, pH, salinity, drought, temperature variation, heavy metals, and oxidative stress [ 3– 9].
As you are conducting your research, look for information about the country that make it more or less susceptible to outbreaks of infectious disease, such as droughts, temperature, rainfall, other climatic factors, wars and conflicts, number of births, population growth rates, infant mortality rates, etc.
Floods, droughts, temperature and biotic interactions have potentially quite different impacts on cholera seasonality.
OO Drought, High Temperatures 'Leaves 36 Million People Across Africa Facing Hunger' as an unusually strong El Niño, and record-high temperatures, has had catastrophic effects on crops and rainfall across southern and eastern Africa.
But it is a different kind of drought because temperatures are warmer.
