Response to drought stress in soybean germplasm. Signaling pathways to cope with drought stress conditions at the molecular and biochemical levels. Limited water availability and extreme temperatures induce ABA-dependent or independent pathways, including the synthesis of water channels, the expression of signal transduction molecules, and transcription factors that regulate such pathways. At the biochemical level, this type of stress activates the accumulation of osmoprotectant sugars, modified amino acids, and anti-oxidative enzymes.
