Exogenous melatonin induces salt and drought stress tolerance in rice by promoting plant growth and defense system

open access: yesScientific Reports
Due to global climate change, crops are certainly confronted with a lot of abiotic and biotic stress factors during their growth that cause a serious threat to their development and overall productivity. Among different abiotic stresses, salt and drought

From osmotic imbalance to germination arrest: key physiological nodes in the drought-alkaline interaction of alfalfa

open access: yesFrontiers in Plant Science
Alfalfa (Medicago sativa L.) is often constrained by factors such as drought and salinity-alkalinity in cultivation. This study aims to investigate the differential response characteristics and physiological-ecological mechanisms of alfalfa during the ...

Exploring plant tolerance to biotic and abiotic stresses [PDF]

open access: yes, 2007
Plants are exposed to many stress factors, such as drought, high salinity or pathogens, which reduce the yield of the cultivated plants or affect the quality of the harvested products. Arabidopsis thaliana was used as a model plant to study the responses

The importance of periodic droughts for maintaining diversity in the freshwater environment [PDF]

open access: yes, 1996
Whereas some species may rely on periodic drought conditions for part of their life histories, or have life strategies suited to exploiting the habitat or changed environmental conditions that are created by drought, for other organisms it is a time of ...
