Microbiome structure variation and soybean's defense responses during flooding stress and elevated CO.

Introduction: With current trends in global climate change, both flooding episodes and higher levels of CO have been key factors to impact plant growth and stress tolerance. Very little is known about how both factors can influence the microbiome diversity and function, especially in tolerant soybean cultivars. This work aims to (i) elucidate the impact of flooding stress and increased levels of CO on the plant defenses and (ii) understand the microbiome diversity during flooding stress and elevated CO (eCO).
