Differential gene reactions reveal drought response strategies in African acacias.
Article in The Plant journal : for cell and molecular biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Drought tolerance involves a complex series of genetic reactions that expand over time as water stress intensifies. We investigated gene expression reactions over 43 days of drought stress in two widespread African savanna trees: the umbrella acacia (Vachellia tortilis) and the splendid thorn acacia (Vachellia robusta). Using 80 transcriptomes from droughted and watered individuals over time, we developed and implemented an analytical approach to identify genes with different reactions between a watered control and droughted treatment population of each species while filtering out genes changing similarly in both populations as part of normal growth and development. Our results show that both species use similar genetic systems to modulate photosynthesis, redox homeostasis, and hormone signaling, but they activate these systems using different sets of genes and on different temporal scales relative to the intensity of drought stress. We also find strong evidence that drought tolerant umbrella acacias demonstrate a surprisingly limited and relatively passive transcriptional response to drought stress, while splendid thorn acacias attempt to actively combat drought stress and maintain a steady state of growth and photosynthesis. Our study provides the first transcriptomic analysis of African acacias and a new model for investigating transcriptomic reactions over long periods of stress.
