Drought Stress in Legumes

About this Research Topic

Plants are challenged by diverse environmental constraints, among which drought stress is increasingly important. Meteorological models predict an increase in the areas prone to be affected by drought in the future. Legumes are important sources of fiber, oils, and protein constituting an essential amenity in the global economy. Additionally, legumes contribute to nitrogen input in the biosphere due to their ability to establish symbiotic interactions with diazotrophs, collectively named rhizobia. Therefore, efforts to decipher the metabolic, physiological, and agronomic responses are crucial to contribute novel strategies to aid drought tolerance in legumes.

This Research Topic is focused on including the latest advances dealing with legume responses to drought. Increasing the knowledge of metabolic adjustments in plant tissues, through metabolomics, proteomic and transcriptomics, can be an important tool to identify key molecules or pathways to be used in crop improvement. Also, a special interest is focused on the interaction between legumes and associated beneficial microorganisms (rhizospherical, endophytic, epiphytic or symbiotic).

The aim of the current Research Topic is to cover promising, recent, and novel research trends in the legume responses to drought stress. Areas to be covered in this Research Topic may include, but are not limited to:

- Effect of drought on biological nitrogen fixation.

- Biotechnological approaches to overcome drought stress in legumes.

- Reactive oxygen species and antioxidant system responses in legumes exposed to drought.

- Impact of drought stress on reproductive traits in legumes.

- Microbiomes associated with drought tolerant legumes.

Please note: Descriptive collections of transcripts, proteins, and metabolites, including comparative sets as a result of different conditions or treatments, will not be considered for review unless they are expanded and provide physiological and/or mechanistic insights into the system or process being studied.


Keywords: Legumes, drought stress, ros, microbiome, nitrogen fixation


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
