The training dataset was generated using EarVision: automated ear image quantification of mutant vs. wild-type allele transmission from competing pollen, letting us determine effects (strong reduction in fitness vs no effect) for >300 GFP-marked mutations in pollen-expressed genes.
Building a large(-ish) gene-specific quantitative phenotype dataset: A. A mix of 1:1 GFP-marked mutant and wild-type pollen compete to generate seeds on a maize ear; B the EarVision platform provides GFP vs WT kernels counts that quantify mutant effects on pollen fitness.

Really happy to see this paper out! Bioengineering PhD student @sebastian--mueller.bsky.social led work building machine-learning models that use omics data to predict reduced pollen fitness for specific maize mutants, with strong performance. academic.oup.com/plcell/artic...

Successful predictive modeling of pollen fitness phenotypes is enabled by measures of expression specificity
Abstract. The ability to predict phenotypes from genotypes in multicellular organisms remains limited despite rapid advances in genotyping and phenotyping

The growth of #plant leaves is highly dynamic and should be coordinated, but how is #leaf flatness preserved? @roederlab.bsky.social &co show that global coordination of growth across the leaf blade is needed to maintain flatness in #Arabidopsis @plosbiology.org 🧪 buff.ly/QUMxOcF
While WT leaves progressively flatten, jaw-D leaves curve at the base. Gaussian curvature displayed as heatmaps on wildtype (left) and jaw-D mutant (right) leaf meshes. Gaussian curvature represents both the magnitude and direction of curvature such that values further from zero represent greater curvature. Orange arrows indicate high positive curvature that develops at the base of jaw-D leaves. Black scale bars = 200 µm.
