Editing Abiotic stress (section)

===Impact on food production===

Abiotic stress mostly affects plants used in agriculture. Some examples of adverse conditions (which may be caused by [[climate change]]) are high or low temperatures, drought, [[salinity]], and toxins.<ref>{{Cite journal|last1=Gull|first1=Audil|last2=Lone|first2=Ajaz Ahmad|last3=Wani|first3=Noor Ul Islam|date=2019-10-07|title=Biotic and Abiotic Stresses in Plants|url=https://www.intechopen.com/books/abiotic-and-biotic-stress-in-plants/biotic-and-abiotic-stresses-in-plants|journal=Abiotic and Biotic Stress in Plants|language=en|doi=10.5772/intechopen.85832|isbn=978-1-78923-811-2|doi-access=free}}</ref>

* Rice (''[[Oryza sativa]]'') is a classic example. Rice is a staple food throughout the world, especially in China and India. Rice plants can undergo different types of abiotic stresses, like drought and high salinity. These stress conditions adversely affect rice production. Genetic diversity has been studied among several rice varieties with different genotypes, using molecular markers.<ref name=":03">{{Cite journal|last1=Yadav|first1=Summy|last2=Modi|first2=Payal|last3=Dave|first3=Akanksha|last4=Vijapura|first4=Akdasbanu|last5=Patel|first5=Disha|last6=Patel|first6=Mohini|date=2020-06-17|title=Effect of Abiotic Stress on Crops|url=https://www.intechopen.com/books/sustainable-crop-production/effect-of-abiotic-stress-on-crops|journal=Sustainable Crop Production|language=en|doi=10.5772/intechopen.88434|isbn=978-1-78985-317-9|doi-access=free}}</ref>
* Chickpea production is affected by drought. Chickpeas are one of the most important foods in the world.<ref name=":03" />
* Wheat is another major crop that is affected by drought: lack of water affects the plant development, and can wither the leaves.<ref name=":03" /><ref name="S.

* Maize crops can be affected by high temperature and drought, leading to the loss of maize crops due to poor plant development.<ref name=":03" />
* [[Soybean]] is a major source of protein, and its production is also affected by drought.<ref name=":03" />
