Arbuscular Mycorrhizal Fungi Mitigate Drought-Enhanced Herbivore Performance in Maize.
Article in Plant, cell & environment, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 events are becoming increasingly frequent and intense, posing major challenges to crop productivity. Beyond direct water stress, drought can indirectly affect plants by enhancing herbivore performance. While arbuscular mycorrhizal fungi (AMF) have been proposed to alleviate drought stress and to enhance plant resistance to herbivory, their role in mediating plant responses to the two combined pressures remains poorly understood. Here, we examined the individual and interactive effects of drought, AMF colonisation, and herbivory by Spodoptera exigua on maize (Zea mays) performance by combining a semi-field experiment with growth chamber assays. Drought reduced maize biomass (by 21.5%) and chlorophyll content (by 8.2%), while AMF improved reproductive traits. In particular, AMF colonisation increased the number of ears (from 1.1 to 1.4) and ear length (from 22.5 to 24.3 cm). Interestingly, drought transiently decreased DIMBOA-Glc levels in maize leaves, an effect that was exacerbated under AMF colonisation. Consistently, drought increased leaf herbivore performance by 32%. However, AMF colonisation mitigated the drought-induced increase in herbivore performance, even though leaf damage levels remained similar, indicating a post-ingestive resistance effect. This study highlights the need to consider multi-stressor interactions to harness AMF benefits in agriculture under increasing drought pressure.
