Illustration showing a human brain in the background representing biological neural networks, overlaid with an artificial neural network model in the foreground. Input nodes represent combined plant stress factors, such as fungal infection and waterlogging, which are integrated through interconnected layers to predict plant traits. The output highlights predicted plant height, demonstrating how machine learning models can analyze complex stress interactions and their effects on plant growth.

In the upper left, a circle with three arrows on it represents extrachromosomal circular DNA containing the GS2 and EPSPS genes. On the right, a section labeled "Metabolic herbicide resistance" depicts an irregular shape representing a cytochrome P450 protein containing a heme domain shown as facilitating the metabolism of the chemical bentazon by adding a hydroxyl group. In the lower left, a section labeled "Horizontal gene transfer in parasitic plants" depicts a clipart of a mustard plant connected to the amaranth by tendrils of the vinelike dodder plant.

Flower color variation in Digitalis purpurea comprised violet, pink, and white morphs that were distinguishable in bee vision, whereas the inner nectar guides remained largely conserved across morphs, potentially limiting pollinator discrimination. Bumblebees were the main pollinators in all populations, but visitation patterns were population-specific, and morph frequencies were not associated with soil composition despite regional differences; only soil phosphorus was slightly lower beneath violet individuals. Reproductive fitness varied among populations but not consistently among color morphs, indicating that floral color variation is not driven by pollinators or soil conditions and is more likely maintained by local or neutral processes.

For each species dataset, an alignment of 10 random leaf outlines including 100 pseudo-landmarks extracted from each species dataset. The tip of each leaf is marked with an orange circle, and the base of each leaf is marked with a blue circle. The vertical black line next to each leaf represents a 1 cm scale bar. For each species dataset, the total dataset mean leaf is represented by a black outline, which is superimposed onto the colored species mean leaf. Image credit: Hightower et al., 2026
