In the context of climate change, associated with increasingly frequent
water deficit and heat waves, there is an urgent need to maintain the
performance of soybean the most extensively grown legume before it
declines. The objective of this study was to explore which plant traits
improve soybean resilience to heat and/or water stress, with a focus on
traits involved in plant architecture and nutrient uptake. For this
purpose, two soybean genotypes, already shown to have contrasted root
architecture were grown under controlled conditions in the
high-throughput phenotyping platform 4PMI where either optimal
condition, heat waves, water stress or both heat waves and water
stresses were applied during the vegetative stage. Under stress
conditions the two genotypes displayed contrasted architectural features
traits such as root width, root angle branching or number of roots. By
correlating architectural to functional traits, related to water, carbon
allocation and nutrient absorption, we were able to explain the stress
susceptibility level of the two genotypes. This cross analysis of plant
ecophysiology and architectural traits under different stresses provides
new information on the adaptation of soybean and can inform future crop
design, particularly under changing climatic conditions.18 Apr 2024Submitted to Plant, Cell & Environment 18 Apr 2024Review(s) Completed, Editorial Evaluation Pending
